Re: DW's 3dr Cossie 24v TT Racecar

[quote=graham bahr;1470020]yes as far as the rules go, but to be honest i think you would have to put a lot of effort into developing a very high reving engine for it to be competitive[/quote
was thinking more of having some fun rather than seriously competing,
I had thought the 2.4 was just a short stroke 2.9 but there are more differences.
would a short stroke 2.9 lump using a 2.3 crank to get under 2.5 litres be possible and would that equate to
say 2.9 could get say 240 bhp then 240 divided by 2.9 times 2.5 would give around 206 bhp
or doesn't it work like that

Re: DW's 3dr Cossie 24v TT Racecar

Why does the cvh need to be very high revving, I thought they made loads of torque and over 250bhp relatively easily with a hybrid turbo, accralites etc

Dave I think Graham was referring to the 2.4 v6 not CVH

My brother mucked about with RS turbos a few years ago and got good power and torque but NOT reliability,the problems he had included:cracked blocks,shattered pistons,head gasket failures and even a snapped crank
He never owned one,they were customers cars,he had cossies both saphs and escort but eventually went on to build a 750bhp 2.4l evo 5 mitsi which actually never broke!

Why not give the TTV6 a try? You could always go 4wd using RS or XR parts.

yes it was the 2.4v6 that was what i was referring to

the 2.4 also has a smaller bore than the 2.9, it all depends on if you want to be competitive, 206 bhp with an iron V6 in a sierra would basically be a mobile chicane as far as all the other cars go

Now that made me laugh

Re: DW's 3dr Cossie 24v TT Racecar

Would save me from being a mobile chicane tho

Re: DW's 3dr Cossie 24v TT Racecar

Appreciate the input chaps, I don't know a lot about cvh turbos apart from the figures that people 'claim' to get, but even if they are true I guess they are spending a lot to get them reliable.
The V6 would only be viable in turbo'd form, or big capacity or multivalved if N/A, all of which would put me in higher classes again anyway.

To be competitive I know we could build a quick class D pinto (once again quite a costly build to get genuine power) or keep the current engine and be able to beat some, but not all of the class A cars. or the third option which would be to base my car on one of these and run in class B with an easy and cheaper 450 bhp....

oh well knock that idea on the head then, perhaps i'll put a 2.9 in and do some track days

Get yourself a cheap boa 24v and you'll have a torquey 200+bhp and loads of fun. The smaller colognes are supposed to be crap to tune and even the 2.9's aren't that cheap to tune

Re: DW's 3dr Cossie 24v TT Racecar

Gonna get the car prepped to go up to the painters in the next couple of weeks now and the plan is to just give it a freshen up and a layer of paint which will just leave us a little bit of plumbing and wiring to do and to get whichever engine it will run with set up.

Would like to get the 24v running just depends on how much need spending on it to get it installed properly. May need different manifolds and such to get it how I want it.

Got someone looking into the small block 302 route too for me which is very cost effective and a lot lighter (ally heads etc) and a LOT simpler than what I have now but we'll see..

Heres how the plenum is fitted now to clear the bonnet with a rough idea of how one side of the intercooler would plumb in. I have enough samcos to do it I think, just need to make a new inlet for the throttle body with a 180 deg bend going either side of the plenum. Also fitted a new V6 rad.
Might put the plenum back round the right way but only if I can get the throttle body on the front without doing too much to the bonnet

Re: DW's 3dr Cossie 24v TT Racecar

Right 24v engine is now officially for sale

The build of the car is still full steam ahead, especially as the mrs and I are now settled into our new home and running out of shit to buy for it

The build is somewhat going off at a tangent (nothing unusual for me I know) but I do have virtually all of the bits to get it done. I've listened to a lot of advise from some wise racers out there and it seems futile to jump straight in at the deep end with a class A car, not to mension the fuel and tyre costs involved. Plus class D is where all the fun's at..
The way its going now is a route I've covered mostly before and therefore shouldn't encounter too many problems. I have a couple of people helping out and between working on Andy Pipes car this one should get done fairly quickly.

I'll probably start a new thread next weekend when it all really kicks off (it's too different a build to keep it here) and in the meantime my T5 gearbox, 24v twin turbo engine etc are to be found in the for sale section on here. Oh and the white 8x18's on it have to go now too..

Cheers, Dave

Looks like clases C and D is where all the fun will be next season what with Billy posibly moving up a class to chase Richard.

Yeah Bill will be a big threat in class D for sure as long as his engine is reliable. My car is much bigger though so along with Andy's 'full fat' spec escort I'm sure we can create a good road block

shame to hear the big 'beasty' is going

best of luck with it david

Cheers, looking forward to using an engine that I can happilly take apart and fiddle with myself
