On this low-compression engine, we found 32 degrees total mechanical advance (vacuum advance disconnected) at 3500 rpm to be the best configuration for power without detonation. . Cars with higher compression ratios will probably need a little less advance. A too-high compression ratio is the bane of supercharging. Click here to review the installation instructions, click here for FAQs, or continue reading for benefits and an overview of the project.
