725 HP Turbocharged 426 CID Engine Upgrade       

HPE700

426 Cubic Inches of Forced Induction Fury

"The result is a tire-shredding horsepower increase of nearly 75%" – Autoblog.com

After turning your stock 6.1L Hemi into a forged and balanced 7.0L 426 stroker – complete with lowered compression pistons to maximize boost – a custom 67mm ball bearing turbo kit takes full advantage of your new powerplant's potential.

When all is said and done, you'll be cruising in one of the most powerful late-model Hemi's to ever pound the pavement.


The HPE700 Challenger goes 11.25 @ 125 mph:
