Twincam running temperature ?;

Ok the big problem with not having a thermostat is that the engine will take longer to warm up to operating temperature leading to additional wear due to the components in the engine not being at their optimum operating temperature. Typically the greatest amount of wear occurs during start up. Also the oil is at a colder temperature then it's best operating range leading to additional wear of bearings and other moving components due to them being improperly lubricated. The oil is too thick to flow properly and your engine is at start up temperature much longer then it needs to be.

I once had an engine that actually ran hotter without a thermostat due to the water flowing too fast through the radiator, & the radiator not able to remove the heat from the water. Slowing down the water flow with a thermostat brought the temperature back to normal. But it was a Ford, so who knows !!! :?

what woops and panda said. the thermostat is there to regulate the flow of the water, you can actually have the water flow that fast through the radiator that some of the water molecules straight line it down the tube, not touching the sides, and not absorbing the heat. thats another reason why modern radiator tubes have turbulators inside.

high flow thermostats are for use with larger radiators, as you need to maintain a good speed through the core, just not too fast...

very interesting posts there , the car is getting its final tune done this week so ill double check with the bloke on what a good running temp would be , its currently sitting in the high 80s at the most 90 . will soon see how is goes after giving it a hard time , might have to get an alloy radiator built
thanks everyone for there line of thought
