Hi Iain,
CT is Connecticut USA and they are on Eastern Standard Time..
Smokey Yunick as one of the first to recognize that the flow of the coolant was not just important to making and controlling HP, but significantly important to the successful creation of HP in the higher RPM ranges. The Reverse Flow systems would concentrate the input of the cooler water from the radiator into the heads first to control combustion chamber and valve pocket temps, then the pre-heated water would be ushered past the cylinders where the least amount of cooling is actually needed but the stability of the higher temperature aids in the control of the cylinder-wall / ring interface as well as allowing tighter clearances for the pistons. Later they came up with the higher silicone content pistons that are now known as Hypereutectic pistons.
For the purposes of my GT40, I will be using remote electric cooling and may well do a reverse flow system - but first I need to do more research and have a better understanding of the current SBF cooling system design. |
