LAKE TEST POST-INSTALLATION CHECKLIST After installing the Whipple supercharger kit it is imperative that the following checklist be performed. Failure to perform these simple tests may result in severe engine damage. 1. Make sure 91 octane or higher is in the vessel. If unsure, then drain the tank completely...
Install a quality fuel pressure gauge to the extra port at the auxiliary fuel rail added by Whipple (1/8” pipe). Attach the fuel pressure gauge with a long enough hose so that it may be visible during operation. Under WOT, full boost, max rpm, the fuel pressure should be 45 lbs (+/- 2lbs).
