Hellcat Pulley Size

Shouldn't need a tuner since they have MAF sensor. That should adjust for additional boost. Additional rpm would help but will need the tuner for that. I'm more concerned with traction at this point! Extra boost will come later.. Spinning ain't winning.

Well I'm in Pa so my car won't be on the track or road for awhile! I'll let some of these other guys be the guinea pigs for all this stuff and see what happens. Like to get a few stock runs to see where were at before making changes. 30+ years of drag racing taught me one change at a time!
