New Rotrex C38R Supercharger

tiller

around $2750 for the c38r unit not $700, if it was $700 I would have ordered 4 of them, iam waiting on more test results before I pull the trigger. but I do know my c38-91 is a great unit already, and jinnxx, we can get a few more pounds of boost out of them now to, ill let you know how it works out, iam gona be the guinee pig for this test and ill post how it goes.

Are you looking at trying to change the impeller on the c38 to get a few more lbs of boost ...I was looking at that myself ..but needed a backup plan if I trashed the unit....back up plan being a c38r lol

No, got 80mm pulley, 85mm is close to maxing our sc, but I did all the math and by bringing the cars redline to approx 7k I should be fine, that be close to 15lbs of boost or more, I don’t redline my car a lot And like to make as much torque as early as possible, with ecutek tuning it’s a simple trial, if not Just switch back to 85mm.

Some added jwt cams, flywheel, clutch etc etc will contribute also

And then wait for c38r result so cuz you all know I’ll get it know matter what
