Euro R manifold and P28 - Tuner-Junction

DCxMagus · #1 (**permalink**) April 28th, 2006, 08:13 PM

OK I noticed that the Euro R manifold only have 1 set of runners right?

So using this with chipped P28 would be like taking out the secondary runners on the stock H22a4 intake manifold right?

so if I wanted to use a P28 and get over the fact I"m going to lose 5-10hp below 5000rpm I would be a good idea to use this intake manifold correct?

actually, its pretty much the same manifold EXCEPT for the fact that those cars didnt have the iab's like you mentioned. and i dunno about losing 5-10 WHP by not having them. i have the p28 from phearable and i didnt notice much of a difference at all.

but that thought process seems correct, like it would be better to use the euro r manifold with the p28. i dont know for sure, but i defenately know what youre saying.

well I think you only lose a couple to the wheels I think it's 5-10bhp and its only in the low low range that it's bad, I would be intrested in the torque loses if any from that in the low end actually.

you wont feel a difference at WOT...plus when are you at 2-3k at WOT?

the plenum on the euro R is also smaller and i believe the runners are longer as well. If you get that manifold, pair it with a 68mm-70mm throttle body and have the throttle body port matched to the IM and have the IM ported. good power
