Whipple-Blown Camaro ZL1 Makes 868 HP on Pump Gas, 929 HP on E85

By -

New heads, camshaft, headers and a 2.9-liter Whipple supercharger add about 300 wheel horsepower to this Camaro.

The video above comes to us from the Vengeance Racing YouTube channel and it features a sixth generation Chevrolet Camaro ZL1 stretching its legs on the dyno. This Chevy muscle car is equipped with the 10-speed automatic transmission, so in stock form, this ZL1 would make somewhere in the area of 570-580 rear wheel horsepower. However, this car is far from stock and its dyno numbers reflect that, with nearly 300 extra wheel horsepower on pump gas and roughly 350 wheel horsepower on E85.

The Build

The highlighted feature of this silver sixth generation Camaro ZL1 is the 2.9-liter Whipple that has replaced the standard 1.7-liter LT4 supercharger, but this car has far more than just a blower swap. Owner Jason Leiva initially came into Vengeance Racing for their in-house heads and camshaft upgrade package, along with long-tube headers, a cold air intake, new upper and lower pulleys, a methanol injection setup and the items needed to run E85.

With that build around the stock blower, this Camaro made 770 rear wheel horsepower, but Leiva wanted more power, so he headed back to Vengeance for some new upgrades. This trip included a 2.9-liter Whipple supercharger, a 103-millimeter throttle body, a vented catch can and some engine bay dress-up items. This setup includes a 3.5-inch upper pulley and a 9.1-inch lower pulley, leading to 16 pounds of boost.

Dyno Blast

The video is short and sweet, giving us a chance to watch and listen as this Whipple-blown Camaro ZL1 works out on the dyno. After the quick run up through the gears and the hard pull, we see the dyno sheet with some mighty impressive numbers.

On 93-octane pump gas, this Camaro ZL1 made 868 horsepower and 817 lb-ft of torque at the rear wheels, but with E85, the numbers jumped to 929 horsepower and 868 lb-ft of torque. Those are solid gains over the first build number of 770 rear wheel horsepower, while presenting massive improvements over the stock numbers.
