SMIM Showdown! Lets figure this out once and for all!

Yes balanced flow has it's place and is important in that place. Where did the stock 1g manifold rate?

Please don't stop testing!!!! Good stuff. This is why I registered to this forum. I think you should go to the next level since you have the manifolds (if you get permmission). Do better than what the vendors do. Log the volume flow difference on a common setup like 272s and a stock exhaust manifold varying from 20-30psi and typical intercooler piping diameter and typical intercooler. There's lots of variables there, but so many choose close to the same thing WRT sizing and cams, that you will find good data for many.

Hmm apparently tubulance had no effect on flow numbers as some manifolds flowed less and had less turbulance than others and some runners of the same manifold had more turbulance but flowed in the same area or more than others.
