2008 Silver Challenger GSS HP2

This is not a gentleman’s muscle car.  This car is simply big and bad.  It’s a Challenger on steroids.  The idea behind this was that we wanted to build a streetable Challenger that could also run on the drag strip.  In order to do that, we had to make a lot of changes.

It all started with the engine internals.  Because of the extremely high horsepower, it required new rods & pistons.  The cylinder heads and cam shaft were reworked.  Headers, exhaust system, Meth injection were also done.  There were a lot of parts that we had to beef up just to handle the power, such as the drive shaft and transmission.  At the end of the day, we built a really fun car that you could drive to the dragstrip and run in the 10’s (you had to turn off the A/C to run in the 10’s, though).

This was a very successful car and we made sure to change the appearance to reflect it.  We added a Superstock style hood with blackout treatment on the hood and rear deck.  Special stripes to let you know what you were looking at.  Big meaty tires left no doubt that this was a car that was built to go fast.  It was a blast and I’ve had a lot of fun with it.
