High HP from Rons MFI Throttle Bodies

Rons Fuel Injection provided MFI throttle body flow data so that we could analyze the power potential of these low cost, simple fuel injection systems. Racing engine sizes and horsepower potentials were determined at these flow cfm numbers for 100% air density, and are included. Rons FI MFI Toilets 3-3/4″ = 1240cfm: can feed 595 […]

Pulsing the Fuel Curve

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 […]

Those racer builders were the performance leaders of the time with amazing achievements!   Front mounted superchargers were common. Fuel splits of around 15 to […]
