Help Series: Racing Applications

This series of videos demonstrates different applications and how Pro-Calc can be used to tune for each. The whole playlist is approximately 42 minutes long. You can watch it from start to finish or you can look through each video by clicking on the playlist icon in the top left corner of the video.

Drag Racing
Demonstrating setting up jetting for a drag racing application: A normally (naturally) aspirated 540 ci V-8 racing engine on methanol is featured. The presentation is about jetting for the low end without a high speed bypass. That would be for the launch as an example. It is also about jetting for the high end with a good high speed bypass. A Kinsler fuel pump is selected. Jetting is described for optimum fuel mixtures (air to fuel ratios -- AFRs) for both the torque peak and HP peak. Fuel pressure determinations for better engine response and weather corrections are also featured.

Land Speed Racing
Demonstrating setting up jetting for a land speed application: A normally (naturally) aspirated 300 ci 6 cylinder racing engine on methanol is featured. The presentation concentrates on jetting for a good air to fuel ratio for the high end. A Hilborn fuel pump is selected. The setup concentrates on jetting for optimum fuel mixtures (AFRs) for high end operation. Fuel pressure determinations for better engine power and corrections for high altitude are also featured.

Sprint Racing
Demonstrating setting up jetting for a sprint racing application: This video is a demonstration of ProCalc, our fuel injection jetting calculator, for setting up good mechanical fuel injection jetting for great elapse times around a circle track. While it is targeted at stack type FI setups, this tuning would apply to various other applications including tunnel ram / hat or throttle body setups that may be used in auto or boat racing. A normally (naturally) aspirated 305 ci V-8 sprint car engine is featured. The presentation includes jetting for the low end torque peak for coming out of the turns. It also features jetting for the high end. A Waterman fuel pump is selected. The setup includes tuning for optimum fuel mixtures (AFRs) for both the torque peak and horsepower peak. How to determine good fuel pressure for better engine response is featured. Provisions for weather corrections are covered as well.

Tractor Pulling
Demonstrating setting up jetting for a tractor pulling application: A normally (naturally) aspirated 620 ci V-8 mountain moter is featured. The presentation includes jetting for the torque peak as well as the horsepower peak. A Waterman fuel pump is selected. Other fuel pumps from Rons, Kinsler, and Hilborn are also considered. The setup includes jetting for optimum air to fuel ratios (AFR) for a wide engine speed range. How to determine good fuel pressure for better engine response is also examined with ProCalc as well as corrections for weather.
