just wonering guys is their any reason not to use a cossie 4wd manifold on a 2wd engine for a 380/400 bhp car on a 34.63 turbo?

i have read they allow for a better torque curve

 

Aren't they NOT needed for that power James???

I know that's no great help, pmsl

I may be wrong of course

 

In short no there isn't.

 

sorry guys just edited to say exhaust manifold ,it just looks tidier than a 2wd one in the bay lol

 

You goon

 

im a gooner pete

 

I could be wrong but i'm sure it was said by reputable tuner once that over 500 a 4x4 becomes restrictive.

 

Over 400 odd I believe, but intake manifold has same problem @ 400 elbow restriction.
Apparently better response on 4x4 Manifold (due to it shorter length) but I am told by a tuner drag chap that this is not nes true .


Tim.

 

not a hope of me getting near 500 ,so should be ok


better reponse would be good tim
