I race dirt oval so the motor never really gets a chance to rest and the races are only 5min long even the main. I read your tuning guide and I think it will be a big help I printed out so I can reread before next weeks race!
I don't have a GX series motor the motor I have is a modded 3 port
R2500-M00HSG that has 1/2 gallon through it. Does this motor adjust the same as a GX series? I know I'm using a sport motor for a racing application but the club I race with most guys run Dynamite sport or platinum series 21. I don't want to get too get our club into a high dollar motor war so basically we have a gentlemans agreement to keep the motors under $200.
Changing pipes can change engine temp. id say the 053 had a different top end pulse from the baffle .. this may have slowed gas flow out the pipe and kept heat in the engine. Yes you can use the engine tuning guide for the RTR range .. its designed to get you in the ball park or at least have somewhere to refrence.
