WRC vs 4wd
Someone knows the advantages from a wrc exhaust manifold vs 4wd manifold ? How will a TT T38 perform with the wrc manifold ?

It will perform well
The wrc is a even pulse manifold
The last t38 engine on wrc manifold made 460 bhp

Thanks. Is the 4wd a even pulse manifold to ?
My Mountune built engine is already 450 bhp with the 4wd manifold, do you think the wrc manifold would make it better

Depends who you use to map it, speak to the person who will map it and see what they advice, but slightly below the standard 8:1 cr is the norm

.
The engine is finished long ago, it's a mountune engine with roller barrel, 8,2:1 comp, 4wd manifold and TT T38.
Why do you think Mountune went for slightly higher comp ?
search youtube "mountune escort cosworth"

They are used to doing rally engines so probably try to stick to quite a high compression ratio, I guess, other wise I don't know !
