Key elements for drag race engine tuning are having a well-tested fuel system setup, tracking the weather for changes in the amount of oxygen in the atmosphere, and properly adjusting the engine for the current climate. One element specific to mechanical fuel injection tuning is idle adjustment for a good starting line temperature. Engine oil […]
Spark plug discolorations after a run are an accumulative indication of engine temperature. The spark plug plating discolorations after a run indicate the portion of the spark plug that experienced higher temperature somewhere on that run. Spark plug readings are most effective when a strong baseline is developed. If spark plugs are not discolored after […]
Testing for maximum 60 foot performance should be done first. Jetting, accelerator pump, transition circuits, float level, and/or fuel pressure adjustments should be done for this first phase of drag racing performance. After carburetor adjustments are done to optimize the 60 foot time, then further adjustments can be done for mid-range and high-end performance. Specific […]
For many classes and national events, both the fuel and often the fuel supplier is specified. In that case, there is no fuel choice. However, for many others such as local bracket racing gasoline setups, that is usually not the case. The selection of gasoline is first dependent on leaded or unleaded. Racecars driven to […]
How important is data-logging? Data-logging is most valuable if the data is analyzed and understood. Bob spent 5 years as a rocket scientist for General Dynamics Aerospace. There were 10 pounds of data for every pound of manufactured rocket metal. All that data was analyzed to fine tune the finished product. We am seeing the […]
For a new setup, a conservative ignition timing value should be the first thing a tuner should dial in. Other setups, including the fuel system and the chassis, should be optimized before the timing is extended beyond a conservative value for more performance. The amount of timing depends on the strength of the ignition. For […]
Video: How to set up fuel injection jetting in a ProCalc calculator A baseline is the default jetting setup. It is the starting point for tuning for air density changes at a subsequent race. It may also be the starting point for a new FI setup. ProCalc provides an easily retrievable record for precise numerical […]
