Vq35hr 20psi stillen blower

Vortech even rates the unit at max boost 17psi. the si is rated at 22psi max but those are outlet pressures so it will be a couple psi lower at the manifold. They are going to have to spin it into the "danger zone" if they want to hit that pressure. the unit has a 52000rpm redline so no more than a 6.9:1 step up without risking ripping the impeller apart.

the charger is already geared 3.6 to 1 so max input pulley speed is 14,444rpm or a little less than 2:1 from a crank speed of 7500rpm.

Stay tuned and we will all see where it ends up after the motor is broken in.

I'll stay positive about it as I know the man building the setup personally and his race history in the industry. I wouldn't doubt him for one second!
