I sent in my 2.85 upper pulley for the Griptec work. The car still has stock upper pulley,
but I am always wiping off the belt dust. I had great luck with their upper pullies before and even gained 1.5 psi on previous Hellcat going from Metco 2.75 to the same size Griptec 2.75 but I wanted a clutched upper pulley for the Redeye.

Apparently I lost my warranty with the car sitting on the lot not getting the 6 month oil change haha.

Looks awesome, but let us know how it holds up. Stock lower? No idler pulley, right?

Stock diameter ATI just so I can side pin the crank. ID 1300 injectors, and American Racing headers.
I have not fully made up my mind on Barth flex fuel tuning or JonX96.
The car only has a unlocked PCM currently but I have been stalling to install everything.

I highly recommend @Jonx96 he tuned my 16 M6 with very similar setup. He’ll have you fixed up quicker for less $
