The ideal Temps for any car much less a race car is 195*degrees on the water and 220*degrees on the
oil.
If the
oil got up to 300-350*degrees, there would be a failure coming with conventional oil .... at 270* regular oil tends to start coking and loses it ability to lubricate and keep parts away from each other. That is why
Synthetic oils have become big in the market..... because race cars and street cars are operating their engines at much higher temperatures especially with Turbo's that generate tremendous heat.
All of our Race motors run at the ideal temperatures above and we never use or need a oil thermostat because it requires to much additional plumbing and fittings that will restrict the oil flow to the motor.
Like you said, cover the oil cooler to get more heat into the motor if needed.
And BTW .... the oil we use is 0w50 Mobil 1
Synthetic in our GT cars as well as our Indy Motors.... has the best Clingability, Lubrication when first start up especially if a motor sits for many weeks at a time, and has a lot of ZDDP for the tight tolerance's we use in specific situations, along with the ability to handle the Heat of racing conditions with Turbo's as well as Normally Aspirated motors.
