Camaro ZL1 First Tuning Starts: 493 RWHP on Dyno [Video]
When the first examples left the factory in Oshawa, Canada, they did so with a V8, packing 580 hp and 556 lb-ft (754 Nm) of torque at the engine, making it the fastest factory-built Camaro ever.
But for some people that’s not enough! When Fastlane dynoed a stock ZL1, it put out 462 at the tires, which is decent. With a tune they got it all the way up to 493 rwhp. They installed a cold air system to improve the air to fuel mixture and will soon also fit sports cam shafts that stay open for longer.
