In our drag racing, we did use air to fuel ratio as a controlled value to get the engine into a linear range. That task is an extensive explanation through out writings. The linear range is where the engine is completely predictable. We achieved that very well in our racing. (more…)
QUESTION: Do any of your books help in areas of tuning with using O2 sensors? I am needing some what of a baseline for a good tuneup using the correct nozzles, pills to help with getting the most or should I say most consistent in drag race ET’s. Of course everything being the same.
Thanks for replying, R. in Texas
Hi R in Texas,
Thanks for your inquiry. Our Jetting for Racing Mechanical Fuel Injection … book has info on O2 sensors including accuracy limits.
REPEATABILITY VS ACCURACY: O2 sensors are a great tool, however, the accuracy (especially for methanol or ethanol) and repeatability may be issues. Accuracy is less of an issue if they are repeatable. (more…)
Jennifer here. I am the webmaster for this site. I am pleased to announce a new project I’ve been developing on the side and I hope it can be useful to a lot of racers out there. I have built a new website that takes real-time weather data and uses it to calculate air density, density altitude, grains of water, and other relevant weather information. I hope a lot of you can get some use out of it.
