My objective when buying this car was to see what the car would dyno at in stock form, then add just a supercharger too see how it would react. Keep in mind I only added the 2.9 with the 123mm CAI and 72lb injectors. I am still using the stock exhaust, TB, and pulleys. Cars base dyno runs were at 430rwhp. After the install and a tune from Jon Lund, the car put down 600rwhp. 170rwhp increase with just one bolt on is insane. Keep in mind its only pushing 14psi. Next up is exhaust followed with the TB, then the boost will increase. I am thoroughly impressed with these cars every day and their potential. There is not another vehicle out there in this price range that can compare. Special thanks to the Lethal Camp and Jon Lund and the whole GT500 community. Here are a couple recent pics of the setup.
