Setting up a new MFI fuel system: main bypass adjustment to control the air to fuel ratio adjustment of the combination of the main bypass and nozzle sizes to maintain an optimum fuel pressure range from the lowest to highest engine RPM. Changing the main bypass jet for tuning affects the air to fuel ratio […]
Outlaw ProMod drag racing setups with mechanical fuel injection are hitting over 4,000 horsepower. The oversize PSI screw blowers at high overdrive ratios are common. These are not legal in most national drag racing classes. But in eighth mile outlaw racing, they are common. Horsepower levels in the 3,000’s are typical on the launch with […]
When we released our latest book, High Horsepower Tuning for Mechanical Fuel Injection, we received a very kind letter from Jim Kinsler of Kinsler Fuel Injection: To: Bob Szabo I have enjoyed reading through your “High Horsepower Tuning for Mechanical Fuel Injection”.

We are now developing techniques using our jetting calculator to set up idle air to fuel ratio for really good MFI racing engine tuning. Idle settings in many MFI racing engines are key to superior performance from engine temperature and off idle response. That is done by adjusting the combination of idle vacuum (throttle blade […]
