Stock Looking Camaro SS Makes 1387 RWHP On The Dyno! Sleeper?

Most of the time, a late model Camaro SS wouldn’t really fall under the “sleeper” category, but when you roll up on one, even if you hear a gnarly cam chopping up, you wouldn’t expect it to be making more than 700-800 horsepower, and even with a healthy shot of nitrous, it wouldn’t be too much over the 1,000 horsepower mark.

You certainly don’t expect a very understated 5th gen to be hiding a twin turbo kit under the hood that cranks out just under 1,400 horsepower. I mean look at this thing! Stock wheels, no fender exit exhaust, no huge intake sticking through the hood. There are literally no externally visible clues that this thing is rocking a Hellion twin turbo kit that is capable of cranking out these insane horsepower numbers.

The car, for those keeping score and considering a sleeper build of your own, is a 2010 2SS with a 427” ERL block anchoring the twin-turbocharged engine. Brodix heads that have been ported and an MSD Air Force intake that tucks nicely beneath the factory hood. The Hellion kit crams air in while the Fore Innovations fuel system matches the demand for fuel with E85 and a methanol spray keeps things nice and cool, allowing the engine to run happily at 26 pounds of boost.

The dyno runs are simply a thing of beauty, except the first one, when the rear tires screamed for mercy as they spun on the dyno despite being strapped down nice and tight. They grab a few lucky bystanders and add a few hundred pounds to the car to help it hook up, tighten down the straps as tight as possible, and get back to it.

At nineteen pounds of boost, the car laid down a stellar 1156 horsepower and an even more impressive 1155 ft/lbs of torque. Building any car that has such even HP and TQ numbers is a thing of beauty because it results in a smooth power delivery throughout the RPM range, meaning there’s good, useable power at any speed.

Cranking the boost up to 23 PSI, the numbers climb to 1278 horsepower and 1276 ft/lbs, and the final pull at 26 PSI is good for 1387 HP and 1387 ft/lbs, some beautiful numbers from a car that could easily be mistaken for a heads/cam/bolt-on car unless you go under the hood. Now, I want to see what this thing does on the track, on some stock-sized drag radials, and what it does from a 60 kick against some other badass cars!
