Re: Racing main jet calculator
I haven't seen anyone use one for a few years now. Most racers use a weather station and some sort of jetting computer - usually from a NASCAR store.

Re: Racing main jet calculator
Hi Dave. Yes I do and I use it routinely. Richard is correct about most racers using weather stations. I looked at a few and a decent one can run a couple hundred dollars. They are definitely handy but I use the Mikuni "slide-rule" at every track I go to and refer to it throught the day. If jetting is already on the edge and the temperature changes enough on an early morning pass, the slide ruler can help make the decision to jet up and maybe prevent some piston damage. It's a good and inexpensive tool to help guide decisions.
