George raised this question the other day, and it is a good one, with considerable practical and theoretical interest. Tom made an interesting observation about his experience with it. As we all know
Many years ago I raced corvair-powered Porsche in European hill climbs. Before that I had a 283 Chev with a light aluminum flywheel and always loved the way it would grab the revs. I lusted for that
I would think a heavy flywheel would be the best for Bonneville for short tracks like El mirage and Maxton maybe something lighter. Turbo Rick http://www.turborick.com /// /// land-speed@autox.team.n
Dave, we're talking about one of the all-time Masters of Bonneville here, the record book is full of Lattin-Gillette team Ardun records. As to the con-rod breakage risk, that is a fact, not a theory
Your theory or Surtee's theory would be valid if there were no exhaust stroke.. Give it some thought.. every engine cycle there is exhaust stroke with no real pressure above the piston so you are sti
Dave, there is still pressure over the piston on the exhaust stroke as it pumps the exhaust gas, the exhaust valve stays open a long time after TDC. Granted, the pressure is not as much as on the com
Bill I have dynoed a lot of engines and we instrument the pressure in the exhaust. The average is so minimal as to be unimportant with an open exhaust car..Been there done that have data to show it.

Give it some thought.. every engine cycle there is exhaust stroke with no real pressure above the piston so you are still in the unsafe condition you describe for 50% or the time. I believe it would
It really can't amount to more than a 1 atmosphere change. I would suspect what happens is the oiling system has problems to be honest. First you have negative g loadings and the oil goes to the fron

Dave, I agree the pressure in the exhaust system with open pipes will be minimal, but it must be more in the cylinder. The exhaust valve and port are a restriction and the piston is pumping. Cheers B
