The
Oil Thermostat controls the speed at which the
oil Temp get up to temp first....... around 200*degrees ..... especially for Aluminum motors.....
Then the size of the
oil cooler will control the end result oil temp ......
If you run the motor hard and it goes over 250*degrees ....then you need a larger oil cooler.....
220*degrees on the oil is the optimium oil temp at speed......
