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.
Judging by all your post on other threads you obviously know everything about anything, so I'm not even going to waste my time going through specs, danger zones versions, etc...

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!
