This is for those who are running cast iron manifolds what kinda hp are you making. I have a f22b2 accord and i'm looking at using a cast iron manifold since spoolinperformance only has 1 f22 manifold left and i won't have the money for a while. I want to make like 330-340 whp. Could you guys with cast iron manifold post dyno graphs?

 

i made 420 to the ground on 17 pounds on a b18 with a cast mani..

 

I am running 15 lbs on a cast ebay mani on a D16z6, I street tuned it so i don't know hp, but i would think in the range of 275 or so, since my 450's are maxed out.

 

A quality cast manifold will hold 400+ no problem. Cast iron is very strong.

 

I made 292 whp @ 10 pounds on my b18c1 with a egay cast manifold.

 

369HP and 291Tq with a SPA top mount cast iron.
