i wanted to know what kind of hp can you make on the Rev Hard Cast Iron Manifold. wanted to know if you can get 550-600whp with the cast iron manifold.or should i look at getting the Rev Hard Tubular Manifold? or the Mild Steel Equal Length Manifold. if anybody has info dyno charts or has one them self let me know thanks

 

dunno about 500-600. i highly doubt it. i made 320 on my cast iron manifold. i'd go with the tubular or full-race manifold

 

Ive seen 600+ on the rev-hard t4 cast manifold. , and 550+ on the T3.

 

Im pretty Sure Brian from GroundZero is still running a RevHard Mani and hes got like 570 something I think

wow! thats impressive. means i don't have any excuse to get rid of this ugly *** manifold

 

At those kind of Hp numbers (500+) wouldn't a tubular manifold yield pretty significant gains?

yeah, the inlinepro is basically the same, just different material and WG placement

 

Boosted99Si on here layed down 400whp on his revhard mani with a built ls/vtec and 20 psi.

 

wow thats alot thanks for the info. any body else with info or numbers would be nice
