ACM | Melbourne Red shop car with headers on the Dyno

After months of having the ESS VT-2 supercharger on the car, we knew there was still more we could get out of this setup. It has been said that the stock headers are high flowing and not restrictive; therefore minimal gains if any would be made with aftermarket headers on a N/A S65. However, this wasn't proven on a supercharged car so we decided to change that. We picked up a set of Schmiedmann Headers to be paired with the full Akrapovic GT4 exhaust. Today's dyno run had put down 548 wheel horsepower number proving a gain of 18 wheel horsepower from the headers.



The baseline run we did a few months ago before the headers put down 530 wheel horsepower.




Here is the comparison of the Schmiedmann Headers(Left) vs Stock(Right)



We installed them with the block in the car.



Full Akra GT4 blued, man we love Titanium!
