Don't the pro stock boys run ice water on the block and heat the oil either in the pan or outside like in the trailer and pour it in before leaving to run ?
Cold engine, very thin oil for Pro Stock. A very bad idea for a bracket car or street car.
If the OP is worried about cold start issues he should be using a 5 winter grade oil, or even a 0 winter grade.
I had a buddy that would only run 20w50 oil. He was stuck on that because that's what he always used, and like everyone else, he had a superstitious streak as big as Texas.
So I set him up on the loose side and let him use his oil. And naturally, every spring and fall, cold starts and even starting for eliminations could send the oil pressure through the roof. Sitting for a hour on a 55-60* day will drop the oil temp pretty quick.
So he decided on off season to install an oil heater. Did all the research. I said let's run a quality 5w30 oil, tighten up the bearing clearances and forget all that crap. He wouldn't budge.
The first thing he learns is it takes a while to heat the oil. You can't just get to the track and plug in the heater and an hour later be ready to go. So he decided it was better to leave the car out of the trailer and load up the day of the race so he could leave the car in the shop and leave the heater on.
Well, that didn't work too well. By the time he loaded up and drove the hour and a half to the track, the oil temp was back down to close to ambient. Back to the drawing board.
Somehow, he came up with a way to run the heater while the car was in the trailer. Went through all kinds of gyrations to make it work. The car could be loaded the day before and he could leave it on the heater over night and on the trip to the track. IIRC, he came up with some sort of way to control the oil temp so the pan heater didn't run all the time.
That worked ok, but it was a PITA for multiple day races. He either had to run the generator real early in the morning to get the oil heated, or hook it up to the system in the trailer, and use his two rig as a generator.
Finally, he decided it want worth it. We went in and freshened up his stuff, closed up the clearances and used a top quality 5w30 oil.
Problem solved.
