As the graph and chart show, the incremental and total amounts of horsepower and torque that were gained are epic

This entire project was conducted on the Dynojet chassis dyno at All Aspects Motorsports in Chesapeake, Virginia, all in the course of a few hours.

As the graph and chart show, the incremental and total amounts of horsepower and torque that were gained are epic. After simply experimenting with the most-basic, hop-up pieces that can be installed on a supercharged Coyote we gained big power.

As pointed out by Roger Dean, we essentially gained more power than the bone-stock, first-gen, carbureted 5.0s (140-157 flywheel horsepower in ’79-’82 engines) had, and not much less than the 175 horses of mid-’80s pushrod bullets that followed.

We’ve done more than our due diligence to stay at the front of the pack when it comes to checking out the new hotness and giving you the first look on these pages
