Hellion brings a sneaky Scat Pack Challenger to SEMA

by Patrick Rall on

Most of the cars on display at the SEMA Show are modified in a way that creates as much attention as possible, but the Dodge Challenger Scat Pack in the Hellion Power Systems booth was the complete opposite. In fact, when I looked under the hood of this Mopar muscle car, I thought that it had a stock engine. In reality, it has a twin turbo setup that is as sneaky as it gets, so if you want a twin turbo setup that maintains the stock look, this is one that you might want to consider.

When I approached the Scat Pack Challenger in the Hellion booth, I expected to look under the hood and see a bunch of custom piping – possibly in some flashy color – running boost to the throttle body. Instead, I saw a stock 392 Hemi, complete with the factory air box. You can’t send boost through a plastic air box, so it seemed that this car was not turbocharged.

That was odd, considering that Hellion is known for their high performance turbo kits, so I walked around to the side of the car. As you can see in the pictures, it was elevated off of the ground, with a large mirror laying under the car. From that angle, I could clearly see the dual turbochargers tucked up into the chassis with all of the proper piping running to and from the remotely-located turbos.

I began to wonder if this was one of those SEMA project cars that didn’t get done in time. Maybe it has the turbochargers mounted under the car for display purposes, but they weren’t hooked up to send the forced air into the engine. I walked back to the front of the car to examine the engine bay more closely, and there was no sign of forced induction piping leading to the throttle body. Maybe this car just had the turbos hung underneath and a flashy livery to draw attention.

It was at that point that the person working the booth came over to ask any questions. I did have questions and fortunately, the person who had greeted me was Hellion Power Systems owner John Urist. After introductions, I asked him if the turbochargers were not functional yet. He replied by telling me that they were fully functional and that this particular Challenger made around 600 rear wheel horsepower. He then explained that the system on display was their Hemi Sleeper Twin Turbo setup, and that the charge piping that runs to the throttle body is routed through the factory air box, so the engine looks completely stock, but it is actually boosted to make far more power than stock.

Since the show, I had a chance to exchange emails with John Urist and I got all of the key details on this build. If you are looking to build a sleeper Challenger Scat Pack, this might be the setup for you.

Hemi Sleeper

The Challenger Scat Pack on display had laid down around 600 rear wheel horsepower with the Hemi Sleeper Twin Turbo setup with the “base” 62-millimeter turbochargers. That was on just 5 pounds of boost, which is safe for the internal components of the 392 Hemi. With forged internals, the 392 with the Hellion base twin turbo setup can make upwards of 1,000 horsepower.

The Hemi Sleeper Twin Turbo setup is currently only available as a “tuner kit”, which includes the headers, the turbochargers, the intercooler and all of the necessary piping for $7,995. This is a 100% bolt-on kit, no cutting and/or welding is needed for installation, but because it is a tuner kit, you will need to provide some of your own parts, including the engine tune, a tuning device and larger fuel injectors. Hellion plans to sell complete kits with the tuning device and fuel system upgrades, but for now, you
