Yes I did run a Paxton for a while.
Only made approx 8-10 psi & ran low to mid 12's on pump gas w/no intercooler.3400 lb car.
I always wanted to run a turbo,I believe w/a turbo it will make the most power over a procharger or others.
When running a high boost blower,you would or should mod the crank & use a more stout crank key set-up to drive the high boost blower,takes a lot of power to turn a blower for high boost.
With a turbo,,it is basically free power to drive it,but,,,there is a restriction in the exhaust,but,there are no belts,no slipping belts,no belts to change & so-on.
All depends on what you want out of it.
W/a turbo & auto trans,you can boost launch much easier than a centrifugal blower.
My Syclone has a stock original 2100 stall torque converter.
I can boost launch @ 0,5,8,10,15 PSI or more & still only be @ 2100 rpm. Cant do that,(generally speaking ) w/a centrifugal supercharger.
A centrifugal supercharger,boost will come in slowly(for the most part)which is good for getting traction,so generally speaking,a centrifugal blower will not launch @ 20 psi, the boost pressure comes in gradually ,but when it gets to full boost,look out,it will scream!
So ,it all depends on how you set it up centrifugal supercharger.
But w/a turbo,boost pressure it almost lmitless.
