Books and Information for racers
Tips and tricks from Bob.
Several hand sanitizers are reported to be contaminated with methanol. Among those reported on Fox Business News are Saniderm Advanced Hand Sanitizer and several others manufactured in Mexico. Our 5000 Horsepower on Methanol tech manual has an entire chapter on methanol hazards to skin, lungs, eyes, etc. It is reported that methanol cannot be made […]

TIRE BALANCE NOT SHAKE Years ago at a drag strip in Michigan, I was testing my funny car. I thought it had a tire shake problem. Some passerby’s in the pits said “If you can’t drive through tire shake, you don’t belong behind the wheel!” The next run, I launched and the vibration was so […]
Recently Bob and Jennifer contributed content for an online publication. The amount of information they needed was minimal but Bob and Jennifer decided to expand on the content and provide it for anyone who might benefit. Key elements to engine tuning Optimum Air/Fuel Ratio in drag racing Is Ignition Timing the First Thing to Dial […]
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 […]
