Difference between Tubular and Cast Manifold
Well im am going to be running a FP red this summer and meth injection.. Im shooting for 450-500whp...
what would be the gains from a stock cast ported n jeted mani vs a shearfab tubular mani
would i see a 20whp + gain with the shearfab?

This is an interesting question, I'm willing to bet the answer would depend on your boost levels. But with the red 450-500whp, I'm guessing 29+PSI. And the more HP, the more flow you'll want. I was under the impression the tubular manifolds provided this. However, I've heard the thermal properties of the cast manifolds are better. Call this post a non-answer bump for someone more knowledgeable to notice.
