The end of another racing season north of the equator. Thanks to all of our fuel injection, methanol, and nitro book customers, my daughter’s ProCalc MFI jetting calculator customers, our ProTune MFI tuning customers, and special thanks to Mike & Tori at Alky Digger, Nashville, TN, USA for all of their support. They are a dealer for ProCalc and a stocking distributor for all of our books.
Special thanks to Kestrel Air Density Meters, Rons Fuel Injection, Engler Machine & Tool Co. (fuel injection), Enderle, Hilborn, and Kinsler for advertising on my daughter’s air density tuning site: https://airdensityonline.com. The site now provides historic air density data back 5 years for most of the USA race tracks and International race tracks listed on the site. Additional tracks were provided for some of the F1 racing, NASCAR, several kart tracks, and many added tracks on most of the continents around the world.
