Notice the smoke coming from our competitors engines, this is evidence of incomplete combustion.  This loss of  initial power allows us to make more passes at the beginning of a race. Even after warm up laps,  a smoking engine at the start of a race is evidence that there is power loss due to cold combustion temperatures”  Once teams started using the Hot Head engine heater “Our pre-heated engine it starts right up without using the choke.  Our engine does not smoke, that’s evidence that we are getting maximum power at the starting line.
