ROAD///RACE Ported & Powder Coated Intake Manifold
Anyone have the RR intake manifold? If so how is it, power gains, install problems, ex.
Thank You

IMO just pick up a used stage IV IM.

please try a title search. this has been discussed many times and one thread comes to mind in the past three weeks.


RRM is a good IM. the only dif is, they dont cut off the back and port out the plenum.


none the less, it is a good IM and i believe they post gains. you can probably expect 10~15hp

you get that big gains just from an IM?

10-15 seems a little too high, especially for a ported stock Intake Manifold. I would say no more than 5-6 whp.

eh hem, did u see a whp after my number?



anyways, ngm claims 24whp off of their stage IV which is bs. they claimed 17whp i believe off of their stage III. again, my dyno did not show such bolt on gains. actually a loss of 2whp due to a/f going down to 9.8:1. in all honesty again i say expect 10-15HP...... not whp.

NGM claims a 24 whp gain from 6000-6800 rpm which is not BS, they never claimed to gain 24 whp at peak. Ravensfan and I both saw a 20+ whp gain at around 6500-6800 RPM. It added almost nothing at all to the peak numbers but I wasn't really expecting it too.
