Well, here we are at the end of a long dyno tuning session. Big thanks to Justin at J and J Performance for all the tuning of the car. We never really even hit 10psi today. The highest numbers were made on 9.xx psi (mostly high 9s) The car made these numbers at the very end of the day so they would be even better.

Now for some more information that we have found out today. The car has muffler deletes on it but still factory piping. What we have realized is that the factory piping is pretty restrictive even on the LS3s with no mufflers. With the factory exhaust bolted up, the car was making a lot of torque but the horsepower numbers werent climbing as fast at the torque. This to me meant that the exhaust was too restrictive. We then unbolted the exhaust to see what it would do and the horsepower jumped up a ton. These turbo cars are definitely in need for a larger diameter exhaust.

The numbers with the factory exhaust are 580whp and 604wtq SAE corrected. By simply unbolting the rear section of the exhaust, we picked up a free 30 more hp and 30 more torque to the wheels. If this was my car, I would be headed to the exhaust shop immediately and have someone make a nice dual 3 inch so I could pick up the free horsepower. This car on a cold day with a 3inch dual exhaust would make probably even more power than we did at the end of the day.

We will be working on designing a nice 3 inch exhaust here soon that will match right up to the back of the turbo kit.

Here are the dyno numbers for the car today. It freaking flies on the street and is going to be a BLAST to drive back home for Lawdogg.








Fantastic numbers!

Getting that much power on that little boost is a good thing and says alot about the efficiency of these motors. Boost is a measurement of restriction and when you make more power on less boost, that's a Great thing!

JT, you Guys have really stepped up to the plate and hit a home run with this system! Nice job!

Glad to hear that you made it back safe. Must be the color of the car that attracts the cops. Or maybe its your right foot....

Thanks for the Hooters lunch and it was good seeing you again.

Tom
