Title: Wayne's boosted 8 project
Post by: Mr Spiller on March 14, 2020, 10:48:44 AM
Morning all
Thought I’d better start a project thread rather than keep adding to my “I’m new here thread “
So after two successful Greddy turbo conversions to my 8 it’s time for the next project ..
After reading Clive’s race car build thread I was inspired to lose the last bit of hair I have and copy it . So I’ll be selling the Greddy kit and replacing with an FD engine . I know it’s a lot of work but I’ll still have my standard engine car for Trackdays in the meantime .providing Trackdays go ahead due to the current pandemic .
I’ve been trolling for sale pages for the last few months and appear to have bought the basics to make a start , RX8 FD engine mount , engine , manifolds and a few other bits . First thing I’ll be doing is assembling all on the bench to see how it  bolts together and see what’s missing .
So if anyone has  any photos of a fully built up engine  with ancillaries on a bench please feel free to post them up . This will help me a lot as I don’t even know how it all bolts together yet .

I wish you well with your "new" project and know it will be a lot of work, but it will make an awsome road/track car

Loom injectors..brap brap...
If your following clives build rx8 loom..electric throttle. Rx8 pcm with a piggy back adaptronic for boost...nice throttle control and idle. Rx8 dash will work then etc...

Loom - got 2 of them
injectors - just primary so far
brap brap...ha ha
If your following clives build - unless there’s another way to do it ?
rx8 loom..electric throttle. - this is where I’ll need to learn a lot of using the RX8 throttle body
Rx8 pcm with a piggy back adaptronic for boost...- I have the new modular one so will need to find out what special stuff that can do compared to the piggy back one
nice throttle control and idle. Rx8 dash will work then etc...
Thats how id do it!- just like that lol

Looking at some photography from the last track day I done it seems I have bent the front splitter up in the middle whilst loading it on the trailer
(https://uploads.tapatalk-cdn.com/20200404/a31c55c9b3ededc1d366e404cdc13a50.jpg)
If you zoom in it’s pretty clear
Whipped the bumper off and found the culprit - a bent metal hanger (https://uploads.tapatalk-cdn.com/20200404/de20c6b93255902a90f4404112e9afa8.jpg)
Time to invest in some caravan ramps to put under the rear wheels of the van to make the loading angle of the trailer better .
It’ll be touch and go weather I need to trim the back of the diffuser slightly too (https://uploads.tapatalk-cdn.com/20200404/e5b30e3b3bfcd7a51c4cc6a30c1dcbe1.jpg)
Got a car to strip in next few days then it’ll be time to start the build
Can’t wait , but also am feeling quite nervous as I don’t know a lot yet . reading about it is one thing - putting it together - totally different

I’m not sure what capacity the adaptronic modular has yet .
Plan for the minute is get it sitting in the donor car , which is just an old 192 which has sat down bottom of drive for last 5 years , put on what I’ve got , check it fits
See what I’ve got and do a shopping list .
This will take a while to complete
Oh yeah
And read clives  build again ...........

Soon as you have mede some engine mounts everything should be fairly straight forward.

The fd engine mounts from the rear and the rx8 mounts from the centre

If you are making this a full on racing car then I would honestly just get rid of most of the rx8 crap you can

Stick the Adaptronic part number up Wayne! Ill do some research. Be nice to have working 8 dash cluster etc...Clives is a piggy back Adaptronic works in conjunction with std ecu. Runs everything Rx8 fans hvac dash etc. Then the adaptronic takes care of the engine tuning. Its rather nice and neat.

Cool...same as Clives i believe. Upto you if you use cable throttle or fly by wire...id use Fly by wire...i know the 8 will go into limp if the throttle is not power cycled by the etv relay after ign 2. Whether the adaptronic ignores that im unsure.
Youll get nice idle!! Retain peddle etc...just gotta make a plenum like Clives.

Should have explained myself better
Yes it plugs in , but origanal Ecu is binned and it takes its place , no piggy back like I had In T1
To try and work abs etc ( for us novice drivers) is quite difficult as it’s done  in percentages I think rather than real time which the piggy back handled better like the DSC too

Started emptying the boxes to see what fits . I was told the manifold would need some adapting but it’s a good start .
Had to remove the water filler by the thermostat but I’m not sure if the electric water pump may help there . I’ll
Dig that out next (https://uploads.tapatalk-cdn.com/20200501/62467c200559d0fa8121fc6c642d2d8a.jpg)
Temporary bolted the turbo on
Bloody hell its heavy
Needed a socket extension bar to hold the engine to stop it from toppling . Might need a support bracket (https://uploads.tapatalk-cdn.com/20200501/7314a8b8947a98c63008a98e65889448.jpg)
(https://uploads.tapatalk-cdn.com/20200501/6e2e4e03a7678f9b979a1600a195b07b.jpg)
Exhaust pipe is too close but not far off
(https://uploads.tapatalk-cdn.com/20200501/d618856938dc7cf28927b834a3a41ab0.jpg)
Slow progress but plenty of time . Just hope I’ve put it together correctly , biggest turbo I’ve played with is Greddy which is the size of a large clenched fist.
I’ll take the upper inlet manifold off and offer in tomorrow and see how mush of the firewall needs adjustment
Reference what grant  said about the rx8 throttle body , seen this earlier 
Should do the job (https://uploads.tapatalk-cdn.com/20200501/f08108963f1f320db0f6c8850b446312.jpg)

Ha ha yep
I bought a load of stuff together and that was one of them
Just had a look online , judging by the numbers stamped it’s a
Borg Warner air works S400SX3-75/S475( T4 turbine )
Possibly a bit too big for what I need ,
Worth a try I guess

That a frickin big turbo! I mean, I reckon its far too big for you... Boost comes at 6000rpm, and hits you like sledgehammer

Adapter is a real easy route. I will confess the reason I devised a different inlet was that I did feel an adaptor didn't flow into the FD plenham properly and would rob power so I devised my own inlet . You will also find that either the engine will have to sit very low (too low), or you will have to modify the bulk head where it sweeps forward.

Thanks for sharing the info and photo Clive
I’m going to offer the engine in without it and see how much needs adjusting .
Looks quite a lot so may need plan B.
Where could I get a set of studs /(https://uploads.tapatalk-cdn.com/20200502/cb033b52b3264bc857d8e618d7f5ef84.jpg)

That is a big turbo, what porting are you running?

I'm running an s366, which is smaller than yours, good for 600hp, I have a full bridge port motor, but I have also got a small 0.88 rear housing as It is a single entry turbine housing.

If I used a dual entry turbine housing I would go up to the 0.96 rear housing.

The turbo should spool really quickly with the porting

However I am looking at getting another turbo, an S480 with a billet compressor wheel, 1.32 at turbine House on a T6 dual entry. Should be OK for drag racing, maybe not so much for track car due to slower response.

What size is the turbine housing? If you got a smaller one you would probably have clearence and it will spool faster

Yeah, cause mine is S300 series, even tho its Shwitzer, but basically same as Clive has. With 1,16AR it can do around 530 horses @ 1,6 boost and it spools around 3000-3500 rpm. And with big big D shape exhaust ports and BridgePort...

So, that size turbo wont spool, ever

The engine it’s on at the mo is supposed to be full bridge port , with ported inlet and exhaust ports . I bought it cheap without a compression test , just seen videos of it running .
It will eventually  be going a different engine which apparently has Cosmo end and centre plates , the inlet ports  are much bigger I’ll get some measurements and photos up over the next week .
That engine hasn’t been run since the rebuild , this is the one I had the turbo with .
As for turbo sizes etc I dont yet have a clue  , this is another learning curve for me so I’m open to any help and advise
Thanks

Cosmo plates, nice. Wouldn't mind some of those myself. They have the largest stock ports of all the plates

If I use electric water pump like this (https://uploads.tapatalk-cdn.com/20200502/22329767c4f79459c4af4375858fe210.jpg)
I then won’t have a thermostat .
How long would the engine take to warm up properly without one .
With my RX8 I always make sure I have decent oil temp rather than water temp before I turn it off when starting from cold

Wayne, the race car has always had an electric pump and it warms up probably no longer than a normal car, make sure you wire it to run all the time though, as that way you will never run the risk of damaging the engine by forgetting to turn it on.

I see you have a side mount alternator bracket.
That was the biggest mistake I made because a stock alternator won’t fit because the chassis rail is in the way.

If you read my thread, first of all I ran a small motorsport alternator and it couldn’t keep up with the fuel pumps.
Cost me a fortune having a custom alternator made using the small body with special internals.

Clive I remember reading about your alternator , it cost you a small fortune
I plan on using  SPA gauges which I had with the electric water pump which SHOULD kick the pump in and keep it running when it hits target temperature
Sounds  good
Not sure yet tho .........

Yes you will be getting rid of that throttle body if you are converting to an rx8 DBW throttle body

Have you thought of using an fd gear box instead of an rx8? They're longer so engine doesn't have to go back as far or are you having to move it further back to sit on the mount you have?

Just so you know your not the only one to struggle with clearence,, this is as close as I can get mine, actually wanted it further forward another 20mm but just makes the job harder with more cutting and stuff, my gear box is almost in the stock mx5 position.

If I had an rx8 box and clutch it would require me to do as your doing as the 8s is shorter

Thanks Grant
It is currently sat on the mount so that would have to be adapted if I put an FD box and I have a selection of 5 and 6 speed boxes here for the 8 .
Good news on the throttle body then as the 7 one is huge .this will mean a lot less cutting of the firewall .
Wow yours is tight  , but not that bad , at least you still got room for brake lines .
There’s  always the option of getting one like Clive had made I suppose
Food for thought I guess

I think  some of the aftermarket lower inlet manifolds, excessive and elite rotaries, help lower the upper inlet manifold. Would that help if the upper inlet was lower for clearence?

Added benefit of those is also better air flow per rotor  and they have 4 Injector ports on the LIM so you just use 1 fuel rail.

Iv very rarely come across any second hand but they are around.

If you have the rail with 4 injectors then you can block off the Injector ports in the centre iron Or run 6 x 1000cc Injectors OR some 2200 CCs if your looking for some huge power out of that turbi

I'd go for the excessive too as with the elite you would have to buy the whole Intake instead of just the LIM

You are going to make more than 350 with that turbo for sure, just on how much air it flows, plus the bridge ports, your going to most likely pushing 450-500 at 1 bar at a guess

Best start soaking my balls in manure to make them grow for that BHP
I’ll just ha e to check how much lower it is than standard .
But , realistically , it’s needed due to the increased air speed so I’ll need to order u less there’s a cheaper / better one on the market .
I’m all good for saving money but if it’s needed I’ll just have to bite the bullet  and order it

Couple of things.

Use the RX-8 box as the first four ratios are the same as an FD box with fifth just a little higher.

Don’t use the 6 speed box, I broke 4 and 2 while mapping !

Grant you can use an FD box in an 8 or visa versa, by changing the bell housing and tail shaft cover, so every thing stays in the correct places.

For 350 brake, stay with 1680 secondary’s and the lilac coloured 550cc for primarys (you will also find good MPG when off boost)
You wont need any more injector for that and I only use 1680 / 850's for 520 brake   

p.s. have 5mm off each flange face and that would help but I still think the sump will sit too low. ( I flattend two sumps on track)

What do you have to change if you use an rx8 gear box bell housing on the fd gear box? Will the clutch need changing?

I'm definately going to get an rx8 5 speed gear box as fd ones sell for a lot more

You use the stock RX-8 push type clutch with the RX-8 belhousing or  FD bellhousing if you want the pull type .
 
Also RX-8 boxes have a kinder life with less power going through them.

I worked out that you are forever  hearing about S1 and R3 boxes dieing but not 192 boxes.

Good idea
You mean shave the bush on the engine mount ? I like that I’ll try it . Sump is currently same height as the Greddy on my 8 . so it’ll run another 10 mm lower , I could get some harder compound bushes made I guess .
I don’t suppose you kept any templates for the the intake manifolds you had Built . Judging by the photo you added it seems to work a treat ?

I’ve been through 2of the 6 speed boxes in my 8
3-4 gear starts grinding /  falling apart
I’ve used the 5 speed box and it was brilliant , real strong .
Only problem in the 8 , the jump between 3 and 4th was huge and it struggled to gain momentum in 4th

I worked out that you are forever  hearing about S1 and R3 boxes dieing but not 192 boxes.
Just looked at ebay for how much GD gear boxes are up for sale, 500 quid.

5 speed rx8s are 100-150

Is it shorter clutch slave  cylinder or oil filter housing  location ? (https://uploads.tapatalk-cdn.com/20200503/ca0337d9fe41216e60d6b53dc3457457.jpg)

Couple of things.

Use the RX-8 box as the first four ratios are the same as an FD box with fifth just a little higher.

Don’t use the 6 speed box, I broke 4 and 2 while mapping !

Grant you can use an FD box in an 8 or visa versa, by changing the bell housing and tail shaft cover, so every thing stays in the correct places.

For 350 brake, stay with 1680 secondary’s and the lilac coloured 550cc for primarys (you will also find good MPG when off boost)
You wont need any more injector for that and I only use 1680 / 850's for 520 brake   

p.s. have 5mm off each flange face and that would help but I still think the sump will sit too low. ( I flattend two sumps on track)
Clive
Good idea
You mean shave the bush on the engine mount ? I like that I’ll try it . Sump is currently same height as the Greddy on my 8 . so it’ll run another 10 mm lower , I could get some harder compound bushes made I guess .
I don’t suppose you kept any templates for the the intake manifolds you had Built . Judging by the photo you added it seems to work a treat ?

As for the oil filter, if its tight for space I would get a relocation kit, as you don't want to be struggling to change filter, which we do often on these, even more so on a track car.

I remember changing the oil on my rx8 and it was a pain in the arse and that was a stock engine bay

Yeah, 6 speeds are crap. Even tho its based on mazda box, its not, its built by Aisin. 5 speed is basically the same that FD has. However, 6 speed from R3 is built by Mazda and its quite strong, but they are rare.

Clive had a good point on those clutch types. I recommend that you choose RX-8 type. Reasons :
-its easier to modify
-you can buy 8's bellhousings cheap
-with that power, 6speed it is not an option
-with that power, you will destroy boxes, so its better to destroy cheap 5 speed boxes than FD boxes


Also, some one said, Im not sure tho, that 8's boxes PPF mounting area is stronger than FDs box

Morning Wayne,

Interesting point on the gap between 3rd n 4th.
 I bought a 5 speeder for the rotus, and obviously if you’re running a huge turbo you probably won’t notice the gap so much with super torque delivery.

I’m hoping the lightness of the rotus will overcome that gap a bit. I was just wondering what diff you were running while you had the 5 speeder in? If you had an r3 diff or the earlier rx8 diff.

Again I bought an r3 one to close the gaps up a bit. But I’ve not ran anything yet do I don’t have anything to compare it to

You’ve made my day
This is something I do know a bit about
Standard 4.4 diff with 5 speed box will show around 112 mph on the dash speedo in 3 rd gear
I tried the R3 diff with the 5 speed and it’s down to around 95 mph
I’d stick with the 4.4
I done a comparison in Mallory park where Matt had  R3 diff and 17 inch wheels which then roughly equates to a 5.1 .
From the tight  hairpin I’d be first gear with the 4.4 diff
He was second gear . From there we would change gear near enough in same place but I was  always one gear lower
So bottom of straight he was 5th gear and I was 4th
Gerard’s bend he was 4th I was 3rd
I’d that makes any sense ????
What size wheels will you be running ?
And what weight will routs be ?

You've noticed the steering rack is in the way of the turbo manifold? I also have this crap problem. Mine is hitting on the universal joint.

My solution is going to be to put a "dimple" into the rear housing pipe where the UJ hits. My pipe diameter is quite large so should be perfectly fine, what diameter is your piping as you don't want to choke it too much if the piping is small.

Solution 2, get a left hand drive chassis

The turblown ones are very expensive I don't know if they will even work on rhd still

Why are you wanting to reduce it down?

If you are doing then do it as for back as possible, people generally step up the exhaust size to help the exhaust "flow" (the term flow is what a lot of people use and I just don't get it)

If you reduce the pipe down then you are going to increase back pressure which is not good for rotaries.... However if your not measuring these then you won't know will you so doesn't matter

If that is going in to turbo from air filter, do not reduce it. Turbo intake size needs big bore to lett air flow freely.

If reduction is absolutely necessary, you can reduce size for very small lengt but still its not a good idea.

If reduction is for after turbo, so called pressure side of piping, it doesent matter so much. However, really big reduction can cause "friction"

Cant explain it properly...

No I'm going to run methanol for fuel. It just makes things easier in the long run, oxygenated racing fuel is really expensive. Methanol is a lot cheaper even though you have to use more to make the same hp, But you can make more hp with methanol because it has oxygen in it etc

Also mean I can sack off using an intercooler too.

I'm not ordering them just yet, as I'm waiting until I'm back at work as I'm getting a lot of stuff at once from Australia.

Need to make sure your ecu can control the injectors, which I think it can, because it's a new one. Something in the back of my head tells me you had to do something when using a 1680cc Injector on the apex ecus used in rx7s, something to do with low/high impedance

I think Clive mentioned earlier that most people use 2 x 850 in the primaries and 2 x 1680s in the secondaries which is 5060cc worth of Injector

At idle you use just the 850 which just inject into the primary runner which to me, I'd rather be injecting fuel across all 4  ports

Plus you are using this car for track aren't you so having lower engine speed idle isn't too big of a deal to help save mpgs lol

I would want to run 4 x 1000cc or In your case you will be able to run 6 x 1000cc as the excessive LIM runs 4 x Injectors, plus you can run another 2 in the centre iron

All depends on hp goals, what your ecu can do and what the person tuning it recommends

I'm going for the big ones because of methanol.

I'm yet to figure out what fuel pump to use.

Do you know what fuel pump you are using?

Yeah, Grant is right. Running with methanol needs massive injectors. Basically you have to burn more methanol to get same result as gasoline. Like lots more! Same thing with fuel pump and coils, needs to be BIG!

With smaller injectors, things like idle is easier to control. With only 4 injectors, primarys and ofcourse secondary has to be massive.

Friend of mine is building semi PP with ethanol setup. Injectors will be 1300/2200 +one mega, I even dont know how big! Problem here is to build large enough fuel system to support those...

However,  methanol "runs cool" and reduses knocking. If you get it right, you will have awesome power...

Back to intake and exhaust. I usually say that you have to think rotary as an 2 stroke. They do hate if some thing is restricted. Exhaust or intake. So, best option usually is to" over engineer them". For example, all mods I have done, is done to being cabable to much bigger power. Like my exhaust, its 3,5" even dont it doesent need to be. Same thing with intake, it can do and flow much better than my power goal is...

Reason for all of this: rotarys are bastards and dont like to be done loosely its much better do "over engineer" your components, than broke the whole thing in dyno just because your injectors are too small or exhaust wont flow enough...

Hope this helps, Im bored and drunk

Yeah, Grant is right. Running with methanol needs massive injectors. Basically you have to burn more methanol to get same result as gasoline. Like lots more! Same thing with fuel pump and coils, needs to be BIG!

Yep
The reason I asked about methanol was that I have water meth cooling on my RX8
But not methanol fuelling - I now understand
As for the exhaust , I’m all good
Here’s my downpipe (https://uploads.tapatalk-cdn.com/20200508/e1fcd14eafc6db1b7b5f4fbdcc8fa828.jpg)
And the rest of 2 systems I had with everything I bought
(https://uploads.tapatalk-cdn.com/20200508/fedce47c222a2ca3aaa89d081d611f17.jpg)
I’m sure with a few bends and pipe we can make something adequate .
Good news LIM manifold and fuel rail have left the supplier today
Should see them sometime over the next month or so

Delivery of the goods from across the pond is this coming this Thursday . Shipping is quicker now than it was before lockdown  . The TB adaptor from Russia is ordered but they are on strict look down  I believe so could be a while .
Anyhow , in the meantime I will put the turbo and manifold back on - which means removing the steering column  again ...........
And start figuring out the inter cooler size and inlet / outlet locations for the V mount .
Currently looking at a core size of 450x75x300 . There’s 650 mm between the chassis front rails
Not sure if that’s big enough
Is there a way of working out size required by capacity of the intercooler ? Could possibly go 350 long if required

Oh that looks nice
Main problem is the fuse box on right hand side
I’ve moved the ecu box from the left which does open it up quite a bit more . I’ve got plenty of room for length , it’s the width which is restricted slightly for an Outlet elbow where fuse box  is

Can you put the outlets in opposite corners?

You could just run a front mount? Take out the crash bar thing behind the front pump and put the intercooler there?

All the stock ones I’ve looked at in forge have the inlet / outlets equal whether it’s side /top / bottom etc
That’s why I’ll put it back together,  I can see how many bends would be required . Ideally I think top entry on turbo side them middle exit on the other side .
I’m sure if I get a base lined up it could be easily made up somewhere .
Intercooler could go in front but from what I’ve read the V mounts is much better for cooling so I’ll see how far I get

I think people mainly use V mounts on road cars due to space available, I honestly. Think a front mount will cool better it just mean longer piping in some cases etc

V mounts iv seen look like they stop clean airflow into the turbo and end up sucking hot air in off the coolers

V mounts are good though

I like to look at it like this,

Front mount air has to go through intercooler no matter what due to the direction of the fins

V mount the air can go through both intercooler and radiator at same time, radiator probably run cooler as not getting intercooler air.

How ever the fins on the v mount intercooler aren't angled to help push air up, Imagine them being at 45 degrees to the floor

However they all work its just what works best for you in the space you have got lol(https://uploads.tapatalk-cdn.com/20200510/856b8f2484195823bb5c18be6fa5ad55.jpg)

Not really I can see your point , find would need to sit and 45degree angle to flow direct through
A bit like brake disc groove orientation
It dont matter which way they go on unless the separating fins between them are angled or curved

You can always mount them a different way too. I like the leaning back or forward version, helps you fit bigger cores, leave room to guide fresh air into the turbo and you can get rid of the air nice and easy too.

I don't know which is better, hot air over car or under the car. I do know hot air will have an effect on aero but that's beyond my current knowledge(https://uploads.tapatalk-cdn.com/20200510/3b7f9da95813109e7fd148479353abe3.jpg)(https://uploads.tapatalk-cdn.com/20200510/6d3b23a3c381381729e52a8288093dab.jpg)

Just been doing some forum reading and most people with rx7s say vmount, I still think that's due to space available for a decent sized core and piping length but I came across this gem of a post

IT doesn't matter what style you use, just get cold air into the turbo and it will be more efficient. Colder air in equals colder air out. (https://uploads.tapatalk-cdn.com/20200510/32efaac846f0ac0f8ac73f6676825490.jpg)

I’m pretty sure we can cut that corner off and fabricate it as it’s a strong chunky bit of stuff that the hoist hook is bolted to .
Now waiting on throttle body adaptor which left Russia on 9th May and the oil filter relocation which should be here early next week
Next
Find an intercooler for V mount and get the manifold altered

After a bit of research , not by me . It seems the alternator relocate bracket is made for FC not FD engine .
It sits back 28mm too far back .
So plan is to try and weld another wheel on front of the original , that will line up fine .
Hope it works , or maybe get a longer wheel from somewhere .

Does anyone have a broken alternator they have laying around that I could have / buy for the wheel ?
Please
In meantime will
Check if one of the RX8 is the same

You could change the front timing cover to an FC and it would fit perfect it think.

That bracket is prety much the same as mine just a different company

Hmmmm
Got me thinking now
If I changed to rx8 one and that worked , I’d have right plug for eccentric shaft sensor for the loom . I think it’s just a bit of machining go to side cover

Wayne don’t fit the side mount, read my thread and you will see it was one of the biggest mistakes I made.

I didn't realise the ECU regulates the Alternator not from inside the alternator, if I had to do it all again, I would have engineered the stock alternator on the car.

Initially I wired up the stock RX-8 alternator wiring before making its own stand alone circuit, lucky I did just grenade the ECU.

The original thinking was from a Race car point of view, use a lightweight alternator  and keep the weight low in the chassis. The stock alternator wont fit down the side.

Also the small alternator had to be remanufactured to give more output as it could not keep up with the draw of two fuel pumps, damn thing ended up costing a fortune. 

Grant you may well have the same issues with your MX-5 car if the ECU regulates the alternator the same way.
Hope this helps

Clive I don't think I'm going to be running an alternator anyway as I have to mount the mechanical fuel pump in the side position where the side mount alternator kit would place it.

Although I have seen some trick things of having the alternator mounted at the rear of the car running a belt off the drive shaft I think nascars do it

The alternator off the prop is an old one from way back, lots of club car specials etc used  and I considered that at one stage when I was having issues,

But it would be a huge task as a metal prop would have been needed to mount a belt drive, plus a big hole in the floor in front of the fuel tank on the passenger side as there's no room under the floor, so effectively the alternator would have been inside the car with a box over it.

OK on a race car as all of this is not a problem,  but on a road car you could end up in traffic stationary and no charge coming out of the alternator.
 
p.s. it cant really run off the drive shaft because of the angle changes unless the alternator goes up and down in the same arc

A question for you , or any one else I guess regarding my track car .
Currently have japspeed ( crapspeed ) adjustable arms on the rear . One broke a while back so am tempted to go back to the standard ones with polybushes
Is the following good that it’s floating or bad because it moving ?
That’s just putting a spanner on the lower arm and moving gently back and forth when in the air

Project cars back in
Only a bit of work but decided to use the RX8 oil filter housing , small bit of machining required (https://uploads.tapatalk-cdn.com/20200717/db23b577f48e1d8dfe7058364326b986.jpg)
And we can use the original metal gasket too
(https://uploads.tapatalk-cdn.com/20200717/4b71d3ad7df94dc0c2836c2dc72de74f.jpg)
Job done
Can easily reach the oil filter from under the UIM as I’ll be using electric water pump . And no fabrication to the bulkhead
Alternator is on , just need to cut 30 -40 mm out of the arm to tidy  it up .
(https://uploads.tapatalk-cdn.com/20200717/f98f53d2e7deba585487ec54c024a0eb.jpg)
All going well should get the Throttle body adaptor on UIM this evening .
Then need to bore everyone about turbo choices again

Customs charges are embarrassing. Honestly iv ordered stuff from Australia before. About a grands worth of stuff and never got charged a penny.

Iv always been charged stuff from America though.

What questions do you have about turbos?

I would first say to you, hp goals, what rpm are you revving it too and how much would you want to spend on a turbo?

Looking at 420 would be sufficient but drivable as it’s a track car so stays in boost rather than loads of lag .
Not sure whether to go internal wastgates or not .
I will have to be careful about noise restrictions on circuits .
I’m told that wastegates  would need to returned into exhaust to keep noise down if the were separate .
And anything I read in the meantime I guess
It’s a rather big learning curve for me so I’m all ears

Plumbed back in WG will be a must. No point turning up to a track and then getting kicked off only to have to get the WG plumbed back in anyway.

420 to the wheels?

Internal WG turbo then I'd say you should look at the EFR turbos. Super fast spooling but they're not cheap at all

You are full bridge ported aren't you?

Probably revving to 9k max.

I will have A look for stuff, but there's loads. Prety much every combo has been done. So there enough info out there

Internal WG turbo then I'd say you should look at the EFR turbos. Super fast spooling but they're not cheap at all

You are full bridge ported aren't you?

Probably revving to 9k max.

I will have A look for stuff, but there's loads. Prety much every combo has been done. So there enough info out there

420 at fly to start will be plenty

GT 35R or what ever the latest version Garret are offering would probably be perfect.

Clive spec turbo would be exactly what your after too.

Different back housing and running. Lower boost at first be perfect.

Bridge ports will spool up turbos quicker.

You can run a smaller turbo but run a large turbine housing

Turbine housings aren't expensive either so you can just swap them when you want to alter your power band and power range

The new G series also come in reverse rotation options so they can fit better. They also don't bother offering divided entry on the turbine side with them because they are so responsive compared to what they used to be, especially with the billet wheels and ball bearing technology.

The 660 number is what HP they are capable of but when you apply that to our rotaries it means less.

My turbo is rated at 800hp on a piston engine but more like 600-650 on a 13B.

So the 660 probably equates to some where in the 400 range

HOWEVER

Because rotaries run hotter than piston engines we can use bigger turbos as we can spool them faster....

The GT35R used to be a great popular choice for 13Bs, fast spooling etc but they now offer that turbo in the G35-900 and G-1050 whereas before people chose them for 450 hp

Absolute minefield.

Pick your budget then look at different options

The rx8 engine BAY, aswell as my mx5 just isn't that wide compared to an FD and FC RX7.

TURBLOWN offer a top mount manifold and a low mount but there's no picture of the low mount manifold

Running the IWG EFR turbo helps you on space constraints for sure

If you can squeeze a 3.5" exhaust in compared to a 3" from what iv been reading you will pick up some hp with an IWG turbo set up, think its down to reducing the back pressure in the exhaust sytem

You wouldn't damage anything having it pulled apart, slight chance you might need to put new water seals when putting it back together but everything else should be OK I'd say.

Take a picture of the exhaust ports with your flash on, might be able to see if they're larger.

Some people don't open the exhaust ports much, some people open them up a lot.

Do you k ow who did the porting on it?

It’s alleged to have a  race bridge port with ported inlet and exhaust ports . The buy was a bit of risk and reward . If it is as said was very cheap . If it does need work it would still sit under the price of a rebuilt engine .
Came from time attack race car .
Hence why I’d like to get it taken it apart to check .

Dont remember any more... But port placement and size does matter, basically it determines how turbo spools up

In right, is original S5 exhaust. In left is mine. Its Pineapple EP4, with 2mm per side wider, and more agressive opening. So, basically, "full race port".

Some dudes here have basically full D shape to get good pulses to turbo. And it works too. But I didnt want to go so agressive (https://uploads.tapatalk-cdn.com/20200719/9a7696386797a7233f2460ff48943103.jpg)

Just had a nosey, it is 600fwhp which is mighty impressive.

The hx50 is equivalent to a GT42, bws475 etc so it's going to make power at a lower boost as it is simply shifting more more cfm

You would find your S475 achieve similar numbers but I would say it will come on hsrd in a short period of rpm.

 Track car you want a more predictable power band, spool early, peak and hold over a broad power band, just like a V8.

Well.. When it comes to US power figures, I dont believe them. Many of them are announcing powers that their turbos can not produce. Its simple math, and specs of their components...

Like getting massive power with stock ports, little boost and too small turbo

However, there some really good shops that can do quite impressive stuff.

What do you mean normalise it?

If it's a rotary comp tester it should be set up for it?

From memory you have to test it at 250rpm?

Although I think it's dependant on how fast your starter spins

The readings are from my 8 engine , had to change the plugs so thought I’d try the the tester out .
Need to pull my finger out and choose a turbo set up for the REW ......
Pete has bought the turblown cast manifold and a turbo with internal wastegate .
So he’ll be limited to around 400 Hp which is adequate .
I’d be happy with that power ,  however , when I’m used to it I’d like the option to increase HP if I can especially having the Cosmo set up as a stand by . Looked at the turbo source ( turblown ) website about the internal wastegate turbo but  they say a Bridgeport engine is better suited to external  wastegate .
Manifold is the biggest hurdle , loads of Aussie guys run a single wastegate low down in the manifold with great success .
Before I get mine adapted need to find out best wastegate and best position for it to be within the manifold so I’m not restricting the manifold in any way . And not messing everything up ....
Need to try and do a lot more research but not getting a lot of time as I’m Very slow in work only using my left hand navigating a keyboard so work is piling up ..........

Ah right, doh.

He's using a cast manifold that fits the rew engine in an rx8?

As for waste gate placement, best place is in the flow path of the exhaust gasses

90 degrees to the exhaust flow it ok

Iv got a tial 60mm wastegate, you should be good with the same unless you just want to use 2 smaller ones

3 or 4 port boost solenoid is what your going to need though, control that boost regardless of what weight spring you have in the wastegate

Yep. Cast manifold from turblown
As for wastegate , I’ve read best to use two smalll ones but will struggle to get 2 pipes  returned back to the exhaust as there’s so little room
Basically need to get something like this (https://uploads.tapatalk-cdn.com/20200801/b4c19a3a8710d0f7a8f4920d533c2cf3.jpg)
Turned into to something like this
(https://uploads.tapatalk-cdn.com/20200801/bfcf74694ec27acc93b766fd9a04cdd3.jpg)
Which shouldn’t be a problem so long as I know what pipe parts I need to get for the two into one adaptor for the waste gate and they are in the right position .
I shall keep my eyes peels for a boost solenoid

If your wanting to make your own manifold then maybe stainless butt weld fittings as you can get all sorts bends and reducers, eccentric and concreic reducers etc OR get  the thinner wall stainless U bends like I used, although you maybe better reducing the pipe size to suit a T 4 flange however, depending on the turbo you choose it might have a v band entry.

Pick your turbo and work back from there?

The turbo source rx8 manifold with dual waste gates looks great but its a lot and requires custom thermostat discharge according to website I'm assuming that means to go ewp

I certainly won’t be welding it , not a skill I hold
Having just read it I never knew they done one for RHD too
I guess I’m lucky I can adapt the one I have as a base point
Shame I could t borrow one from someone to copy and understand what fittings we need to plumb both piles into one waste gate .
So
Garrett G25-660
Is it best speak to them ask what I would get max output on a rotary ? If it’s only say 440 would I be better going for G25-770
Or going up to a G35 ?

Feels like I had the op again today / absolute agony
Skin was growing through the goz stuff . 3 days late on dressing change
Ouch and double ouch
Anyways , back to turbos
Need some further expert advice
Pete has gone for this (https://uploads.tapatalk-cdn.com/20200803/fe57cdd665039ecd76cb58658af3b341.jpg)
And is told he probably won’t get more than 400 HP from it
As you can see it’s 475-750
So if I go G30-770 will I max out on the same or is it different as that one has internal wastegate ?
Any help or advice is appreciated

The turbine housing may be a limiting factor on the paek hp from what I understand. A bigger rear housing will move the power band up but should give more hp

Time for more reading for me ....... and asking more questions then
Its not that I’m chasing stupid HP
Just want to make sure the turbo I get will be suitable for this and the Cosmo engine too as the exhaust ports are at least 5 mm bigger on that one
I know it’s going to be 2k for turbo + wastegates exhaust etc

As silly as it sounds for me to say this after a lot of discussion BUT stick the S475 on and get it running and then you can see how it works because that turbo will make all the power you want

Only thing is the boost response as in the spool up will be very lazy maybe, which means torque will be less however on a track I cant see you being below 5000 rpm but I would say once that turbo gets going it will pull hard for sure.

Bigger turbos shift more air regardless of the amount of psi. Partly why you can see bigger turbos or a turbo with a bigger rear housing making more hp for the same psi as a smaller one.

The amount I know about turbos is just a hairs worth of the info available.

Tuning a turbo for specific goals is like tuning an engine with regards to cam specs, and valves lol


As regards for running twin turbos, if I had the cash I'd run 2 of those new g series 35 660 just because it would look mint

And would sound even better brapoing away because of zero contamination between exhaust pulse sound waves

That’s funny
It’s a conversation Grayo and I had earlier
I think I need to concentrate on the engine that’s in the car not the Cosmo one on the bench . The turbo came with the Cosmo so it’s clearly not right for the one It  as both inlet and exhaust ports are much bigger on the cosmo
And trying to marry a turbo for both is going to be hard or nearly impossible
a bit like measuring boobs
Like trying to get a a bra to fit a pair of medium then rather large ones
It’s never going to fit both I guess ...

So ....
that’s my thinking
Always welcome to others opinion

Yeah, I agree. I went big too, even tho Im not planning to get big power. Early in my build, I desided to get everything done ready to support if I want to go bigger. Engine might do 450-470 ish figures, but fuel system that I built, can support maybe +600 figures, just by changing injectors. Also, there is everything ready for second big fuel pump, and bigger in tank pump

Overtake on the right..no hang on left...yep left!!
But what do you do if slower car pulls over to left and slams brakes on...you go to the right in a split second decision...
Or you get stuck behind a slower than me suoercharged Aerial Atom for 2 laps until he decides to pit
Its just MSE days Waynes more interested in the Novices than experienced track drivers...not pulling over and pulling over on wrong side should be a black flag offence too imo.
Thing is you went right i went right...2 black flags but slow car fully over on left side at run off from church corner at 120mph plus...gets nothing carry on do it again next lap but not us as were getting a telling off in pitlane.
I might email ED.
