Our custom intake porting is a fine addition to releasing every bit of horsepower from your performance upgrade. You can see from the picture below how the intake runners on the LS2 intake are rework. We open them up and smooth out the runners while matching them with the intake ports on the heads. 

This in turn makes for smoother air flow while increasing air volume into the engine. We are seeing horsepower gains of 10 to 20 depending on performance upgrades. This is a big jump in horsepower and gets the same horsepower as most aftermarket manifolds.

You do not need to have one of our performance packages install to have this done. If you would like this done for you GM vehicle. Just contact The Corvette Doctor.

The picture below is a example of intake porting and not our own. We have a special way of doing it and we do not like to give away our secrets.
