2001 GSXR600 optimal engine operating temp?

Anyone know the optimal GSXR600 optimal engine operating temperature? A reference or citation would be nice too.

You could attempt to measure BSFC wrt to temperature over rpm ranges your most likely to use in an enduro. But that is of course using my definition of what factors contribute to an optimal temperature, perhaps you should list yours?

As a rule of thumb I would say what the stock thermostat is set to so roughly in the 80 degree Celsius range.

Keep in mind, the type of loading put into our engines is vastly different from a stock form bike and will run hotter. Most engines run optimally anywhere from 80-100 C. Shoot for 90 C and you shouldn't have any problems.

Optimum depends on the engine, and I don't remember us ever doing a hp vs temp test at school, although I'd be inclind to say 150-180degF. On the other side of the coin, the hotter you run the coolant system, the smaller and lighter your radiator needs to be, so really...how much HP can you afford to lose for the weight gain? Keep in mind systems can be made reliable at very high temps. Engines don't 'burn up' when water is 260deg, they burn up because they get localized boiling which allows parts of the engine to get much hotter then 260. To run high temp systems you must have high pressures.

F1 stat of the day: before a max was put on coolant pressure they ran engines at 300degF with a coolant pressure of 90psi. Radiators could be made not much bigger then a FSAE car.

well, we are from venezuela, maracaibo city and the weather here is very hot(100ºF), we run our engine between 180º - 210º F (engine coolant temperature), sometimes the temperature is more high just a little.
