Used FR500 intake manifold. Sounds perfect for you [and 99% of everyone else in these forums]
We couldnt agree more (at least as far as n/a engines are concerned) The STR (which is our n/a manifold) is designed for serious street cras where the factory manifold (even if ported) is a restriction (this is usually around 400+), a combination that would suit the STR or vice sersa is a high compression (11.5 +), Big cams (.500 + lift and long duration), stroker or BB.
For those that are saying that the losses are where I drive the car everyday, this is true, but no different than installing a big cam on the same engine..there will be losses on the bottom and big gains on the top.
At the end of the day it is important to select the correct intake for your application, this manifold is not for the mild street car that most drive, the point is even when used on an incorrect application this manifold has made more peak power, that doesnt mean it is a great intake or even a bad intake, it just means that there is a place for this intake when used the way it was intended (serious n/a cars and forced induction applications) , a great example is drag race application where bottom end is not a concern on the street but beating the guy next to him at the track is (in an enviroment where the gains far outweigh the minor losses)- and this is the choice any person makes when choosing any cams or intakes.
We are always here to help and if someone would like to see if this intake will benefit their own particular needs we are always here to discuss them!
