It's not often that I'm surprised by the power output of any specific combination, but that changes today. This Hellion Street Sleeper setup put down some INSANE numbers on our Dyno. We have done quite a few of these on stock engines but this car has definitely set the bar for pushing this kit to the limit. The car was put together by Rarefab, our local partner in building some of the baddest cars on the planet. And it also features some killer MPR Racing Engines custom camshafts which are a key piece in this big power! Check out the video to see some BIG NUMBERS!
