HEMI Hump Day!!!
We built this motor a few years back, & since then, it's undergone some upgrades with the 3.8L Whipple Superchargers, Transcended Fabrication & Performance titanium intake, Fore Innovations, LLC triple fuel hanger.
We added a little bit more boost with the ZPE Inc. GripTec supercharger pulley, & dialed in the Modified by KC calibration via HP Tuners
We've gotten this one to run 9.0 in the 1/4 mile, & have a really good feeling about boost weather getting ready to set in over the next couple of months.

This 2015 Camaro SS needed a clutch to be replaced, but wanted more power at the same time. We pulled the motor to upgrade it with a Texas Speed & Performance F35 camshaft & long tube headers. When we pulled it apart we found one of the exhaust valves to have a broken tip when we went to upgrade to the PAC Racing Springs & retainers. We also installed the CHE Precision Inc. trunnion kit.
We mated the long tube headers to a CORSA Performance Xtreme catback as well.
