hi everybody!!!!! what gain would an fc have for performance if you put an fd upper intake manifold in in fc 13bt engine? would it have a better air intake flow? more torque? or horsepower? please give me some tips...

think of it like circumsizing... kinda doing it for the looks, but no actual gains...
you need an adapter or modify the studs/mounts/or manifold for it to work... kinda like you have to wear boxers for a circumsized ***** to work

 

its gonna cost you a few hundred dollars for no performance gain

 

Huh?
Is this info in the FSM and why was I not informed?

 

no performance but it looks great on a FC

 

I have yet to see any real numbers on performance gains. Some people over in the holy forum claimed to have heard of 30HP increase, others volunteer to DYNO the difference but never do it, other on this forum claim there are NO gains while some Claim SOME sort of gain through out the whole powerband. Iceblue had a good post on this too.

I had the same question except that I SEARCHED for the answer and THEN made a thread about it.

 

I have been wondering this same question. It looks really good if your going fmic, but I havent heard anything on power gains. I would like to test this theory on the dyno.
