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

I agree that these tests aren't the whole picture. But, one has to ask the question, "why don't any of these manufactures flow test, or anything other than dyno test their parts."

I plan on showing the constructive critisisim comments to my boss, who will be able to much better answer these questions. One thing I can tell you though, at 30+ pounds of boost, we are forcing much more air through the intake than the flow bench is capable of. Makes you wonder how the incocsistency translates at those levels. I don't think that anybody can argue the importance of having each cylinder having balanced output, which will require balanced input.

It may be because these results do not translate to real life at all, but I am not sure if they do or not. I know when the other SMIM test was done they decided not to do a flow bench because it was not realistic. Instead they put each one on the dyno.

I wish I had more information to help put this together, but I don't. One thing is for sure though, a balanced manifold on the flow bench can't be a bad thing on a real car.

And yes, the air going through a flow bench is not even close to the air going through it at high RPM, the air is at over 200mph in a real car.
