No self-respecting REALracer would suggestNOT using a temp guage.
Who is it that you think invented the use of temp guages?
It darn sure wasn't some backyard basher.
And I've never seen a
blind engine guru at the track
Many 'professional' racers don't use temperature guages. If you know what you're doing, there is absolutely no reason to use a temperature gun to tune a nitro engine. I can tune any engine to peak performance with nothing more than my eyes and ears. That is true for many, many other nitro engine owners as well.
No two nitro engines run the best at the same temperature. Some like it hotter, some run better on the cooler side. If you tune to temperature, youare just wasting yourtime.If you tune to performance, proper operating temperatures will follow.
