Is a Mandrel bent system better then our pressure bent system?
Our competitors are once again claiming that a Mandrel bent system would out perform our pressure bent system.
We decided to run another series of Dyno tests just to find out. This time we ran the experiment on a 1967 Camaro with a small block 350 in it. The 350 was originally out of a 1991 Chevy truck with only a performace cam added to it. It was converted over to standard carburetor from the original fuel injection.

We installed a Mandrel bent system and ran two pulls on the Dyno then installed our system and ran two more identical tests.
These results couldn't be more clear. Our system out performed our competitors system throughout the test on both torque and horsepower.

The highest number obtained during our four runs are highlighted in red.

The machine tested rear wheel horsepower using the WinPEP Dynojet Performance Evaluation Program.
