Or do they make more boost without needing to be spun faster?
I rev to 8250. That puts my blower into a 5% overspin. I hit 22psi boost cut on the dyno. The smaller blowers can be spun faster then the larger ones but the larger ones supply more air/rpm. I never could figure out why the 8th gens didn't make boost but the kits just don'tseem to do it
