 |
|
hi there, simple question as i never seen it done:
is it ok to use a powercap for a turbo conversion?
its bigger than the stock LET tophat and even the bigger replacements for it
plus, its facing the left side wich makes it easyer for the tubing..

Will work, but will still need the dounut rubber as it's a wierd shape and will end up reducing down to 2 1/2 or 2 3/4 which ever size it is!
Nice bottom picture, wonder where you got that from

ooops, sorry dewis, took it from google images didnt see the source really.. 
the comparaison is clear, its a MASSIVE diference..
what i fear is the lack of pressure it may cause. you need it somewhat narrow enough to channel the pressure produced by the turbo.
if it too wide, the pressure will be lost when reaching cilinders i supose...

I don't mind mate
I think for your XE turbo conversion this wouldn't be any good as you would lose presure like you said I'd stick to a 2"-2 1/2" I only ran that big cause I have a biggish turbo running 20+ psi 
for your 8-10psi boost I'd keep the boost piping as short as possible to held with response

how about having a T3 turbo doing the job? would it still be too much? even at the very same 10psi? (planning on LET pistons with xe rods)
its a shame having to sell the powercap but it seems that i will have more problems than gains trying to keep it!
