VIDEO: KP Racing's “Fast ZR” - 2010 Chevrolet Corvette ZR1

KP Racing builds a 1,105 rwhp ZR1 – and breaks a record doing it!

When the C6 ZR1 was released at the end of 2008 as a 2009 model, it set the world on fire. It received rave reviews from Corvette fans and critics alike, and it raised the performance bar for Corvette to a whole new level. With 638 supercharged horsepower at the crank, as delivered from General Motors, it paved the way for tuners to sink their collective know-how into the LS9 platform.

Last week, our friends at KP Racing sent us this video of a 2010 ZR1 that they had recently built for one of their best customers, RC Cox of Willis, TX. RC’s ZR1 isn’t a stocker, nor is it the average bolt-on car trying to make waves in a world full of 1,000 hp street machines. It’s in fact, anything but.

The car made three visits to KP Racing, and each time, it picked up a ton of horsepower. Bone stock, it put down 534 hp to the tires. With KP’s tuning, it would manage almost an additional 600 ponies to the tires – more than doubling its original output. KP Racing’s Amber Huneycutt sent us the specs, in stages as they were performed, on RC’s ZR1. See them below, and watch the video above!
