again this is a normal HR intake Manifold which has longer intake runner Vs the VHR intake ,
Longer runner vs short runner is = more Mid-power Vs top end

now their testing was with an unmodified HR Vs a modified VHR which already has an advantage in the top end 7000+rpm Vs the HR which their advantage is the mid-range

unless you are running most of your time in the 7000+rpm, a similar modified HR intake manifold will yeild better result.

dont get me wrong , im not bashing their work.

It's hard to tell which lines are which, but if we know m370 makes low - mid power over stock, than this does too, but not as much and has better top.

edit: let me clarify. We know the Z1 mod will make power in low, mid and top over stock, but low - mid is not as good as M370. We need a M370, Z1 and stock best run graph to actually see all of this.
