Post by: Timrxmotors on April 21, 2005, 09:43:10 PM
Here I will post some details of my monster turbo 12A,as work progresses.Should be ready for Rotorstock.Well,I hope someone is interested!
Here is a comparison of the stock ports with the new ones.I figured they need to be 3 times as large,as I want 3 times the power.:D

here is the exhaust port and a ceramic coated rotor housing.

Tim...........well done that man, ports look HUGE and ceramic coating, interesting, are we likely to see some dynos prior to RS11? Come on what Turbo, have you given in to some form of IC?

Looking sweet, can\'t wait the see that baby fly up the strip:bandit

Is it me or are there combustion and water seal groves in the 12a sideplate you\'ve just ported? thought the 12a\'s had the grooves in the rotor housings:confused:

Ta,

Hi Tim,
Glad to see some people are not secretive about there work.

Did you manage to get your rotor housings ground for a little clearance?

Looks your next restriction is going to be that tiny little 12a turbo inlet manifold.  Do i feel a custom built LARGE one coming????

Regards

Tony

If you look at the rotor housings you will see there are grooves in them,   I think you might find the end plates may be 13B but its just a rumour.


Tim,
Do you put an o ring in each or do you just leave one groove empty?

Turbo is a GT42 ball bearing one.Manifold is divided,which apparently is a good thing.No intercooler,I have water injection.
Should see the dyno before rotorstock.
Rotor housings were ground to spec,so now my rotors fit.I just hope the coating stays on.
More pictures soon.Expected RWHP? Secret! :)

Is that a standard 1st gen gearbox too ?

its looking interesting, I look forward to seeing it at RS2 (other tuners please take note and post more engine photos :D )

Hi Tim, was there any hassle mating the turbo II box to the 12a? also would you mind me asking what clutch you are running?
  Sorry for all the questions but is that also a turboII throttle body welded onto the stock manifold?
 It looks great by the way.
  Cheers, for any help. If I am being to nosy just tell me my place. thanks, michael.

Gearbox bolts straight on,starter has to be modified to fit.Clutch is a 6 puck solid centre plate on an EGI flywheel.TII throttle body is bolted on.I did consider welding it!

Your right Brian, to me it looked like an FD with a 1st gen body :D He did a good job with that engraving tool on the housings to change the \'13b\' to \'12a\' though dont you think? :D

It has some nice Turbo 2 end plates though!
Bigger inlet port runners than 12a stockies.
still has 12a rotor housing\'s though.
Great job Tim.

It runs.:D .Engine is very smooth at 1500 rpm,anything below it goes Brap,Brap,and the car rocks from side to side.Done 30 miles,it seems to boost very easily,even on part throttle.Next job is to tidy the wiring,honest! Here is a pic of the modified bonnet,with the help of an angle grinder.

I don\'t really need a fan,that radiator is amazing,hot at top,and very cold at bottom.

I\'m sure if he had slammed the bonnet shut hard enough it would have fitted ...
Title: purple peril progress
Post by: Timrxmotors on May 12, 2005, 08:37:53 PM
Done 75 miles now,all is well.Air flow must be much more,as everywhere it is lean A/F\'s.I have so far put in 15% more fuel,and it wants more.Easy on a \'Microtech\' ecu,just press the button til it says 15%,try that on an Apexi!
Been stopped by the police already,he thought it was rather loud,so I said it wasn\'t broken,and is fine.The car didn\'t start for him to hear it when he asked,something to do with that plug I pulled from the ecu.                          :D
Does anyone Know the legal noise limit? Antinuk?
Title: purple peril progress
Post by: antnicuk on May 12, 2005, 08:44:07 PM
Hi Tim,
You know that isnt my specialised area,   but from memory, as long as there a no holes its ok for a roadside tug,  not sure if there is a decibel limit for mot\'s either.  I know there is for SVA but that wont effect you.  As long as you have a silencer and no holes you should be ok.

Does it still go Brap Brap?
Title: purple peril progress
Post by: MikeLMR on May 12, 2005, 08:58:36 PM
1. The vehicle shall be fitted with an exhaust system including a silencer such that the exhaust gases shall not escape into the atmosphere without first passing through the silencer.

     2. When -


(a) the vehicle is held stationary on a level surface such that there is an unobstructed area not less than 3 metres wide all around the vehicle; and

(b) the engine by which the vehicle is propelled is run at a constant rotational speed of 3/4 S, the noise measured at 0.5 metres from the exhaust outlet at 45 degrees to the axis of the outlet pipe in a horizontal plane, shall not exceed 101db(A).
Title: purple peril progress
Post by: MikeLMR on May 12, 2005, 09:02:00 PM
I think thats the SVA limits but you are welcome to search the HMSO site for yourself as it will also be in the construction and use regulations somewhere and I\'m pretty sure the SVA test will be based on those regulations anyway

Title: purple peril progress
Post by: antnicuk on May 12, 2005, 09:26:57 PM
thats what the sva guide says,  they checked it when i sva\'d my kit car but there is no road side test for it.
Title: purple peril progress
Post by: Brett on May 13, 2005, 09:10:24 AM
Exhaust noise is subjective to the policeman or the MOT tester at the time.  The MOT book simply says it must be at an appropriate level for the car.  I think if a Policeman (correct me if I\'m wrong) deems your exhaust to be excessive they can ask you to get it changed, in much the way as if your number plate is dodgy.
Title: purple peril progress
Post by: antnicuk on May 13, 2005, 09:37:42 AM
With number plates there are specific measurements that need to be adheared to,  with exhausts there is no way of telling how loud something is without the correct measuring equipment.  Without a specific measurement an officer would look a bit silly in court trying to explain to the judge that it was too loud.
Title: purple peril progress
Post by: WeasleRx7 on May 13, 2005, 10:04:28 AM
Hi, I did a little research on this matter too.  My interpretation on the matter is that basically there are no noise level limits for normal road cars.  As long as the exhaust pipe has not been modified after its been manufactured to make it louder, then you\'re within the law.  So if you buy a straight through pipe from a supplier/manufacturer it doesn\'t matter how loud it is... as long as you dont alter it to make it louder.

Must say since I had the external wastegate put on the car a few coppers have turned and looked at the car - hopefully it was to look at rather than want to gimme an earful!!

It\'s great fun passing cars as the noise reverberates off them lol!!:D

Yours must be extremly loud Tim!!!;)
Title: purple peril progress
Post by: MikeLMR on May 13, 2005, 12:12:18 PM
Simon,
           I think you\'re almost correct in your thinking but the interpretation would be that you are not allowed to modify a cars standard exhaust system in anyway that would make it more noisy. Changing to a peformance exhaust would be OK as long as it as loud or quieter than a standard exhaust system.

I still think that the limit of 101Db(A) would stand in court ... its the limit stage rally cars (must have an MOT) are checked at

Went to Reworx today to tune my car ready for Rotorstock.Made 349rwhp and would have made loads more,but the apex seals decided to rip up the ceramic coated housings.
:mad:
I now have 4.6 bar compression,which is crap,so engine is coming apart:(
Still breaks traction in 2nd,and spins the wheels all the way to 9000rpm,But that\'s what I want in 4th.
Title: purple peril progress

There probably isnt a MOT station with sound checking equipment, my last imp with a full race 998 & 18" straight thru exhaust needed earplugs to drive anywhere, The mot tester did comment on the noise but said he couldnt fail it for noise but put a note on the MOT sheet basically saying it needed looked at

Hi sorry for digging up an old post although seeing as how this car is now running super quick I reckon it is quite relevant. I am using a turbo II throttle boby on the morris minor and after having a good look at it last night I was wondering/hoping that there might be a fair bit of stuff that could be removed to de-clutter it. The pair of really slow to open butterflies....can they be removed?  I have been looking as much as I can to the pics of your throttle body set up but cant quite make it out, i.e what you have removed.
 any advice would be great, but if they are all trade secrets then fair due.
 cheers, michael.
Title: purple peril progress
Post by: travellinbob on October 20, 2006, 09:04:30 PM
Also might be kinda cool to move this thread to the 1st gen section? possibly, although any possible throttle body mods for more power might be welcomed by the 2nd gen brigade also I guess.
Title: purple peril progress
Post by: Timrxmotors on October 21, 2006, 08:19:09 PM
You can remove the extra butterflies,and the shaft,then weld up the holes where the shaft was.I have a single throttle position sensor,which simplified the linkage a lot.The throttle dampers have gone.
The purple peril now has an RX8 gearbox,6 speed,an OS giken twin plate clutch,FD propshaft uj\'s,FD diff flange,and standard diff,with egi LSD,and I am running smaller diameter drag tyres.
Going to SCR on Saturday to do a 10 second run,before Mr 10 second Ellis does.:rollin

The purple peril now has an RX8 gearbox,6 speed,an OS giken twin plate clutch,FD propshaft uj\'s,FD diff flange,and standard diff,with egi LSD,and I am running smaller diameter drag tyres.
Going to SCR on Saturday to do a 10 second run,before Mr 10 second Ellis does.:rollin

Are you trying to get a part in Eastenders or something?

Tim what kind of throttle position sensor do you use? Do you sell them?
  Let us know when you have time. Oh and how fast was it on the weekend?????????

Hi Tim,

I\'ve been interested in your intercooler free set-up for a while, just wondering whether your WI is pre turbo or post, and what sort of air temps your seeing?

I can answer a little bit for tim here I think, intercooler free is a BAD idea imho, tim has been seeing 150o intake temperatures :) I am sure an air cooler of some description is his next mod, im hoping it will be matt strapped onto the bonnet blowing on the turbo piping. :D

I think he likes to reserve Matts energy for blowing something else.

150....lol, rather toasty then :) Would be interested to see how a pre turbo set-up would affect the temps, thats if it aint already

Its was something I was thinking about playing around with a while back, but have since been convinced otherwise, on the look out for an efficient air cooler solution. Im looking to get the most out of the twins so need something will a small pressure drop, ASP/M2 intercooler is tempting, was also thinking CC but worried about their performance on the track
