So if the Stage I SC has more torque than the Stage II SC, does anyone care to have an educated guess as to which would be quicker from 0 to 62mph?

So my question above kinda got swallowed up in that 0-60 Vs 0-62 explanation. Anyone care to take a stab at it?

It runs anywhere from 7.5 to 8.5 psi on the average. It's impressive how responsive these engines are to small increases of boost. Good luck with your project.

Im guessing its partially to the high compression ratio?

Higher compression can help get response up but the main reason for the responsiveness to boost is the engine design such as the heads (port size\flow), cams, VVEL.
