As I forgot I bidded on this, but i just one a RsT MFi inlet manifold, it has been gasflowed ported and polished out, sell claims it adds 15-20 bhp is this right? I'm not fussed what it adds or not add.

from what is said ther it sounds like evry thing on the inlet side of things would have to be ported and polished to notice a diffrence , charge pipe , inlet , throttle body , head etc

Don't quote me on this ok, but all that will do is allow the air to travel less restricted. Problem is, if the head isn't done in the same way, or throttle body, the air will go rough to smooth to rough again. If what I think is correct, you wouldn't gain much from this as a singular modification

Well I'v got a throttle body in garage and another charger pipe, so i think il finish polishing the out side of those and do try and do the inside my self to. and wait to fit it i start the enigne rebuild and get the head gasflowed and ported and polished.
