Well time to start again i think(track car)

[od404]

on the subject of the end tanks, pointless. why arent they flowed to the bottom of the core? you may as well cut it off where the end tanks finish.

This was my first thought when I looked at the photograph.  The bottom corners are just going to be full of stagnant air, which would effectively reduce the efficiency of the intercooler as your frontal area is no longer being completely utilised to cool the charge that\'s passing though.  
 
Admittedly it\'s hard to get full useage of the area due to the charge needing to be turned by 90 degrees to enter the core, but I would have thought you could get the majority of that out of the way by having full length end tanks?

Another thought on the exhaust idea is the exhaust has to pass the fuel lines and the starter motor and then pass back over to the correct side. Seen that kind of setup you talking about but with the exhaust still on the drivers side and WI pre turbo and the turbo connected straight to the manifold (a 1st gen drag car)

I think we are concentrating a little too much on the intercooler....lets see how well it works when the car is finished

I think Im really missing something here....but why would you want to? As long as the turbo is low enough and far enough away from the LIM then what is wrong with it in its standard place?
 
We have removed the standard pedal box so that has created a lot more room in that area. It seems to becoming overlly complicated here!
 
Remember the car Homer designed?

i just mainly thought that running the exhaust across the front would look good!!:Giggle:Giggle and it makes the piping into the IC easier, just a little straight piece. instead of 90*bends that a lot of people get carried away with saying that "they will restrict flow...blah blah blah" etc.
 
you could just get one of these Lee for when you get the man size turbo

 that would fill the gap nicely and you could run the exhaust down the original side of the engine??
 
and you could just attach that charge cooler onto the turbo, even less piping.

iv seen that car, i think runs on methanol though so theyre not too worried about heat.
 
that would be seriously awesome to drive, instant boost probably!!:rollin:burnout:burnout

I was completely agreeing. My downpipe is close to the LIM, with some ceramic coating on the Turbo and Down pipe and a heat blocker coating on the LIM I haven\'t seen any silly temp rises from the setup. I\'ve been more concerned about my filter position, need to get colder air at the start of the process.

why would you send it back over the drivers side, seems a strange direction change and its just adding more bends into the mix.

If your going to all the hassle of building a race car then i wouldnt run the stock fuel tank, this removes any blockages from running the exhaust on the passenger side.


what ive been thinking about today is a exhausts with my stock turbos.

being honest without fitting big boxes im never gonna get it to pass noise tests at different trackdays and the money i earn means ill only be able to do maybe 6 a year.

with that in mind i might just run an open downpipe with a little 90* downward angle at the end, i dont live far from donnington and they have days with no noise limit(about 6 a year)

It would keep the weight and price down and allow me to run more power due to less restriction(less EBP)

Except the floorpan.

erm... i thought this "race car" was being built for time attack?? thats what you said anyway?

[Grant Monkhouse]

i dont think it matters what he uses the car for, as like with most people, it comes down to money.
 
i think its a good project for everyone to see regardless of what he does with the car, most people compromise when building RX7\'s, whereas this is being buillt for racing only as it wont be street legal without lights etc.
 
when people compromise so that they can do everything, drag, drift, race, daily drive, weekend toy they end up with something that doesnt reach the full potential of what their car could be, i know i compromised with my last FD simply because it was a uk spec car, but if i knew then that it would only be worth the same as any other rx7 when i sold it i would have done it completely differently, interior would have gone straight away, roll cage in, i would have cut the arches to take on a wide kit etc, but because i wanted it to remain possible to turn back to standard, it never was what i could have made it.
 
Lee\'s car however is a no compromise car in my eyes, for one purpose only. RACING, in what ever form takes his fancy.

[MaLicE]

im not disputing that fact, it just seems a lot of things are being said as gospel then it gets forgotten...

couple months back it was being made for time attack... tyres etc were discussed was looking forward to seeing that but now its just a road car and track day car?

[turbotoaster]

well time attack is technically racing, even though really its a glorified qually session.

But at the time i didnt realise the new control tyres would be as bad as they are and dont come in the sizes i want.

Hence i need to look at what i can realistically afford to do with it.

Cant afford to put on the road as its a waste of money, id never use it and the cost of lights, insurance, tax, mot, set of road wheels and tyres will cost me about 4k, thats money i dont have at the moment.

Id rather just use it on a few trackdays a year when i have the spare change.

then maybe next year i can get into racing when i have set the car up properly and know what i can afford.

im hoping when its finished that it will be a \'jack of all trades\' so i can go drag racing as well as circuit work, hence why im so anal about weight, jon knows that if the car weighs more than 999kg ill not be impressed.

the final aim is this

1.5 60 fts and high 9 quarters
1.5 lateral g on track
200mph at bruntingthorpe
sub 1000kg(excluding driver)

alot of people will think im talking out of my arse, but as people can see from the build so far, its not like i havent dont much to it.

im not disputing that fact, it just seems a lot of things are being said as gospel then it gets forgotten...

time attack is mentioned above, plus i refuse on principle to have to buy the tyres from a company that are more expensive than the normal retail price, they should be discounted, not the other way around!

ill still be running 18x10 front and 18x12 on the rear, but most likely slicks as i can get them cheaper than track semi slicks.


its a track/race car, doubt ill put it on the road as id never use it.


will write a little update on the ignition system im ordering aswell as custom dash, clocks when jon puts some more pics up

[RobMatthews]

Any idea what the car weighed when jon raced it?

[AtomicRex]

With the Seibon parts it was weighing in at just over 1000kgs.  Our GRP parts are actually lighter so im hoping it will bring the weight sub 1000kgs

[Grant Monkhouse]

is there a difference in weight between wet and dry carbon?
 
what is the choice between carbon & GRP? the fact that  carbon is stronger and doesnt break easily, or choose GRP because it easier to repare?
 
when i said Racing Turbotoaster i did mean any kind, just meant that the car isnt going to be built soft to take abuse on the roads as a street legal car.
