I also change oil filters after each race and cut it open to see what is trapped inside. A well built TR race motor can easily do double those hours on the bottom end. In my opinion the key to long tern motor health, assuming a good build, is a high quality race oil. My choice is Joe Gibbs Driven XP-3 10-30, I have bearings that look almost new at 50 hrs. using this oil. No such thing as “cheap” racing oil. “Never be beaten by parts” K.
