Ok, thanks Mike for this explanation, it will help many people to understand timing issues ^^
But here in Europe, racing = geared for 43-45 mph and a 1512 just can't run "cool" in a truggy in this condition, no matter the smoothness of the driver finger... Many people encountered heat issues with the small tekin motor in buggies with theses speed and they use now the truggy version of the motor in their buggy. Sometimes they still have heat issues

.
Maybe in USA where the track are relatively short compared to ours, you can use a 1512 in a truggy or buggy geared for 35 mph, but in the European, the tracks countains massive hard turns with long straight line which requires high gearing, and we just can't use small 1512 motor, mean temp for drivers go over 180F wen its 70 outside :(, and the vehicle is a buggy ...
Many people use then neu 1515 or equivalent Castle, but manage to run them at 140-160 F in buggies. I know someone who run a 1518 in a light hyper 9e and his runtime is better than with his 1515...
Geared for 35 mph, i would say "maybe" it can increase runtime.
But for more than 42 mph, I have serious doubt.
Scooterboy, what is the temp of your motor at the end of one run ?
