cossy Turbo or cossy V6 24v

[Graham]

Come on then fellow wedge fans, what motor should i put in the racer

V8's are out as much as i'd love to i dont think it would be practical


so the options are 4 cyl cossy turbo ( cos based on pinto block which they fitted to tasmin)

or

the V6 2.9 24v cossy as fitted to the granarda scorpion ( also allowed as baced on the cologne block)


both motor will fit in either the 185 bhp or 285 bhp classes ( or indeed the unlimited)


but as Wedge peeps what do you think ishould go for

V8's rule BUT.. I'd go for a cossy turbo! Surely the easiest to get power? It's lighter as well isn't it?

[Graham]

lighter yes but more complicated and more difficult to fit, and posibly more expensive.

as for power both classes are power capped so you'd end up with the same max out of both..



p.s. your right v8's rule...

It left the factory as a V6 so stay with a V6. Should rev well and will really confuse people...

Graham,

I'd go for the 24V cossie.. a guy turned up at the Surrey meeting with a V6 24V in an "S".

Very nice installation (by Peninsular) .. 3 downdraught carbs..

Nice !

A side benefit is that if you have the right exhaust system the Cologne engine sounds good, the Cossie is just a boring 4-pot.

Graham, I think you know my opinion!! However on the plus side of the v6 option you can pick them up for buttons....£500 for a complete car. It would also be easier to fit especially if you keep your existing gearbox.
I think it's easier and cheaper to get more power from the 4cyl and it does seem a more popular engine for tuning.
If you are limited purely in BHP then isn't weight a major issue?? If so then wouldn't you be better with the lighter engine?? Not sure what the difference actually is, but the V6 looks a lot heavier.....if it's possible for something to look heavier.

[Graham]

there is always an advantage of the car being lighter, but the bhp limit is a power to weight limit so with a slightly heavier car i can run with more bhp.... so it negates the engine weight problem, although it would reduce the weight up the front which would be a good idea..

[19560]

Better to have the extra power.

nope the exhaust would be no good as the 2.8 has 2 port heads and the cossy a 3 port.

what ever engine the exhaust will run through the bulkhead and through waht was the passenger well.

Difficult decision Maybe you need to drive both to compare. Now where are you going to find a Wedge with a 4cyl cossie and a one with a V6........

Graham,
IMHO - for ease of getting bits I'd go the cossy 4 cyl route.
Though the V6 Cosworth sounds superb when tuned (a la 6R4) - Roger Duckworth (son of Famous Cosworth founder) an excellent National Rally driver ran one in his Sierra and it certainly pulled the crowds.
Though it's a sin to say it - go 4 cylinder.

Graham,

I've dug out the cossie 24v 'S' picture .. to give you any idea of what it would look like in a TVR..

[Graham]

mmm looks like whoever wimped out on the ford ecu as it looks to me like that motors running carbs rather than injection

G

[rev-erend]

Yes - it's running 3 * downdraught webbers..

About 280 bhp if my memory serves me right.. more than
enough to scare a few Griff owners I should think !

Said tweeked 'S4' belongs to 'gbgaffer' if you check the profiles for chat he posts on here. It is a south coast car, if you are anywhere near this neck of the woods for a look. As for power 220 at the wheels rings a bell it is far from a standard 24v cossie though, I believe it was a 'hill climb' special which is why I might have seen him embarass the odd 500, bloody quick is all I'll say .
Oh yeh it sounds like a BTCC car on steroids.

[Graham]

Its looking horribly like a YB turbo might end up in there

due to

1) less weight
2) More bits available
3) apparently a couple of Group n complete cars have been located for 3.5 k each..


I do prefere the idea of the 24v motor with it still being a v6 but i want to be competitive..

Interesting one this.

Your Telling me Its a right pain in the arse...

a) locating suitable motors
b) fitting them
c) Deciding on which is the way to go..

The big problem is no bodys knows which way to go as nobody has done it. Ok both motors have been fitted to road cars but not tried on the track...

im half tempted to buy one of these cossies and stick it in the garage. Stick a couple of big valve heads on teh 2.8 and run the 2.8 for the first couple of rounds..

by then if the 4pot is the way to go the bits to do the conversion should be available off the shelf ish and if not i should be able to break the cossie for what i've paid and go and source a 24v..


The other side to that is dependingon what has to be done to the cossies to export them it might be in a state i could track day it for a laugh in the mean time...

Graham,
What about a Duratec V6 - a la Noble. 3.0l with ST220 cams two blowers, MBE ECU and 380 bhp!!
