Most drag racers running automatics talk about their torque converter’s “stall RPM”. They say things like “I’ve got a 5500 RPM stall converter” or “My converter stalls at 6700 RPM”. Then they are somewhat surprised that when they go to a significantly higher elevation the stall RPM drops. Continue reading “How Could My Converter’s Stall RPM Change?”
Things to Consider Before Top Speed Racing at Bonneville Salt Flats
Top speed racing is very much like drag racing, but just on a very long track. In drag racing, it is power to weight ratio which typically determines your performance. However, when the track is very long, and your vehicle spends much more time at high speed, it is power to drag ratio which is more important. By drag, I mean primarily aerodynamic drag or wind resistance. In addition to aerodynamic drag, there is rolling resistance from tires, driveline losses, but the higher the speed, the larger the aerodynamic component of overall drag.

Keeping Track of your Race Car’s Setup has become easier
Have you ever gone to a track that you haven’t been to in a while and you can’t remember the setup that worked so well last time?

If you’re like most racers, you just expect you will remember it. Or, if your one step better, you right it down somewhere. But now that piece of paper is lost, or you can’t really make out what your notes mean. Continue reading “Keeping Track of your Race Car’s Setup has become easier”

Better than Perfect
When we think something is 100%, we typically think it is the best it can be, that is perfect. One way of rating an engine’s breathing ability is called Volumetric Efficiency. Continue reading “Better than Perfect”
