Here is the before and after Dyno. The car achieved great gains as the factory exhaust was very restrictive. The 3 inch piping increased exhaust flow alot as well as helped with the extreme boost drop you saw on the video screen. Boost went from 14psi down to about 8psi but with the exhaust, it was held strong. That is why we see a great gain in HP and TQ. The AFR was kept consistant and as you can see by the Dyno Sheet, all variables remained the same. With our new exhaust test, the room was actually 8 degrees hotter!
No other mods have been done to the car. We will be testing our crank pulley next.
