Tuned Port Injection is at a new level thanks to a special arrangement with Affordable Fuel Injection to market these completely brand new, TPI fuel injection systems. The TPI units are completely new castings and not reconditioned. These units are produced with much larger tubes for greater air flow and have been tested to handle up to 500 hp from an SBC and flow up to approximately 870cfm. You still get that great low end torque that the long runner design provides you but you will not lose the top end horsepower that is found with stock TPI units. |
