Opinions on HVMCs, pics
The first is of the HVMC header and the second is of the normal header. The high velocity looks like it would be more restrictive giving more torque, but it is supposed to give max HP numbers. Both have the turbulence spike. I'd like to see a cross cut of them. Anyone else thought about this when contemplating spending an extra $450?
Has anyone actually dynoed both on the exact same setup?


I'm definitely going with QTPs I just dont know about that $450.
to a serious racer who is looking for every last bit sure.. but not for the average LS1 enthusiast..
I think itd be lucky to have an extra 8rwhp /6rwtq over the other header in certain areas.
