Lethal Performance Unleash 800HP Mustang GT500 on Camaro ZL1

Video / Comments

The stock 2013 Ford Shelby GT500 is more than a match for the ZL1, so imagine what one with an additional 170hp is capable of.

It hasn't taken long for a member of the tuning community to get their oily hands on the 2013 Ford Shelby GT500 and decide that 662hp and 631lb-ft of torque isn't quite enough power. First blood goes to Mustang specialist Lethal Performance, who picked up a model fresh off the production line and immediately dynoed the car, the result being a figure of 590hp at the rear wheels.

Then it was time for modifications, the first of which was a Lund SCT tune and a new three-inch midpipe for the exhaust system.

That only had a minimal impact on performance so they simply fitted a 150hp boost of nitrous oxide and the result is what you see in the attached videos. Final eye-watering figures were as follows: a total gain of 173.9hp for an output of 763.9hp at the rear and 859.9lb-ft of torque. To see how all that power translated to performance, Lethal Performance took the almighty GT500 to Palm Beach International Raceway where a serendipitous meet with a tuned ZL1 resulted in yet another matchup between America's finest pony cars. As you can imagine, the Camaro received one hell of a beating.
