[QUOTE="Lamar, post: 801554, member: 16675"] Dear Comet; Heat is NOT an issue with NASCAR rides, my friend! Keeping the heat CONSTANT is the issue though! In stock car racing, keeping the engine at a constant temp is very important to keeping the engine performing at the same level throughout the day. NASCAR rides don't use t-stats, instead they use restrictors, which are nothing more than a large washer with a hole in it.
