LISTEN TO THIS SHELBY GT350R HIT 8,200RPM!

by Wes

John Hennessey’s shop strapped a Shelby GT350R to the dyno wearing its new HPE850 supercharger package, running on Shell V-Power 93 octane, and posted a pull that added 311 rear-wheel horsepower and 193 lb-ft of torque over the car’s naturally aspirated baseline. The resulting graph, a dual-scale readout where the horsepower and torque curves cross around 7,400 rpm, briefly confused viewers before the final number sank in. Watch the pull to see what boosting a flat-plane-crank Voodoo V8 actually looks like on the rollers.

Watch the New Chevy Camaro ZL1 Race the Dodge Challenger Hellcat

by Kiril

Fifty-seven horsepower separated the sixth-generation Camaro ZL1 from the Challenger SRT Hellcat, and the Dodge held the bigger number. Hennessey Performance lined them up anyway, and the horsepower column turned out to be the least interesting part of the comparison — because weight, gearing, tire width, and what happens in the first sixty feet decide a drag race long before either car reaches top gear. Read on to find out why 650 horsepower and 707 horsepower end up much closer than the spec sheets suggest.

800 HP Hennessey Escalade vs Camaro ZL1 1LE

by Wes

Hennessey Performance’s 800-horsepower Cadillac Escalade HPE800 lines up against a completely stock 2018 Camaro ZL1 1LE, and the family SUV jumps out front before the Camaro claws back ground at the top end. Viewers immediately drew comparisons to the legendary 1991 GMC Syclone that once embarrassed a Ferrari, and debated whether the ZL1’s manual transmission cost it the race. Watch to see just how close a stock sports car can stay against 200 extra horsepower wrapped in three rows of leather seats.

THE EXORCIST 9.57 @ 147 MPH 1/4 Mile

by Wes

Hennessey Performance turned a Chevrolet Camaro ZL1 into ‘The Exorcist’ — a 9.57-second quarter-mile machine hitting 147 mph, with 0-60 in 2.1 seconds and 0-100 in 4.7. Viewers are just as impressed that it does it all without a dual-clutch transmission, calling it ‘a very impressive job’ on Chevrolet’s part. Watch to see how a factory-based muscle car ended up trading blows with the world’s fastest hypercars.

Hennessey has sold 12 1000hp Exorcist Camaros, Details on How to Buy (Video)

by Kiril

Hennessey Performance took a Camaro ZL1 that already made 650 horsepower from the factory and decided that was not nearly enough. The resulting package carries a claimed four-figure output, a name aimed squarely at a rival from Auburn Hills, and a price that doubles what the donor car cost. A dozen buyers signed up before most people had even seen one run. Read on for what is actually in the package.
