Jeep Wrangler 392 is in the shop. Before we started the tear down process we wanted to get a baseline. Bone stock 392 motor, with a blower, all that flowing through 40's.
Time to get it torn down and turn this thing up.

Mark brought his 2018 hellcat to us with lifter failure. It lost a roller on number 2 cylinder. Yes even "hellcat" lifter can fail. We installed our PD blower camshaft package as well as a lower dampener. The dampener was installed to combat the boost loss from a more efficient camshaft. We put down 738whp and and 656ftlbs on 11psi of boost (stock boost numbers) on 91 octane. We didn't want a risk a before dyno pull but typically stock cats make 620 to 640. Solid gain of 100-120whp. It will be back for e85 in the future!
