If its flowing higher, that just means it doesnt need to spin as fast to produce the same boost. Just because a turbo is bigger, doesnt mean theres more air in 5psi than there would be with a small turbo. Less stress on the turbo yes, more psi in the psi, no.

So "obviously" that's not why. I think the numbers that were throw out there by Z eliminator are pure speculation. I dont think it made GTM look good either. Stage 3 @ 10psi only making low 400 when their actual stage 1 kit is already making 350 @ 5psi.

Wtf is going on here folks? I'm not hating here, but these things aren't making GTM look good for me. I know they are a good company, this isn't necessary or needed.
I don't really know anyone who quotes flywheel HP except perhaps the manufacturer... It's rather misleading.

But yes you're right. Thanks for the "flowing" debunk. Assuming you don't have a closed throttle plate in one of the I/C tubes and you're pumping into the same engine, 5psi is 5psi is 5psi. It's putting the same number of oxygen molecules into the chamber.

With regards to sizing, a smaller SC or turbo has to work harder (spin faster) to make it, which would cause more parasitic losses, but the same amount of air is going past the intake valves into the combustion chamber. The whole "flowing more" is really misleading because the air isn't "flowing" any faster or harder.
