It isn’t Hennessey’s first rodeo twin turbocharging the new Camaro (see the HPE800), but the 4th of July fireworks came early in Texas with our latest HPE1000 twin turbo Camaro hitting the Dynojet for a follow-up to it’s initial 855 rwhp 93 octane tuning session that warmed up its 427 cubic inch LSX engine.

Using C16 race gas for good measure, the HPE1000 was repeating its earlier performance with ease, able to make mid-800 wheel HP pulls on mild boost settings. After things felt dialed in enough, it was time for a cool down and a jump from 18 to 21 psi to see if it could crack the 1,000 wheel HP barrier without having to dial up the boost any further.

How did it go? Check out the video to see the final result:

1021.46 rear wheel HP and 1027.73 lb-ft torque… on the FIRST run, safe as can be. The ease in which it made nearly 1200 crank horsepower (at the motor) gave every indication reaching even higher numbers would come just as naturally. Certainly, the same numbers on pump gas are easily attainable with a few tweaks to the tune.
