Warming up engine to oil pressure at idle

[Belle66]

Hey All,
Happy New Year! While at the new Year's Nationals at Richmond Dragway i wasn't able to get the engine up to the normal temperature because I'd recently changed the intake manifold and went to a lower thermostat, and it was cold outside. Thinking it through I decided to run the engine until I get a fairly low oil pressure at idle. I made it through a field of 42 cars to the finals. I always warmed the engine until I got the same oil pressure reading.

Any of y'all used this method?

BTW: My car is a DD and driven to the track. Nothin fancy 10.4 second in the 1/8.

Poor mans oil pressure temp is watch the pressure gauge. Oil temp is way more important than many realize.

I have researched "synthetic oil" and from what I have found is that it is NOT important when you are using Synthetic Oil to have the oil temp up, in fact, they say you can run the motor with the oil cold and it makes no differences. The Pro Stock cars actually push them up to the water box to keep the motor cold. They go into the water box with a cold motor and launch it cold...from what I have read.

If there were no difference why is the oil pressure higher cold? Pro-Stock is a completely different animal. look and see what oil they run, Ow or thinner. Especially the guys that run 20w50. The thinner the oil the quicker it'll flow at lower temp. Find a bracket racer that runs cold oil and wins alot.

I was looking a gallon jug of dyno-testing/shoot-out oil that was used for a friend's car. It sloshed like it was thinner than water. Not something to drive around on.

Wow! thanks everyone for input. Being a poor man looks like I stumbled upon something good. Interesting conversation!

My car will usually drop in pressure from 75psi to 50psi at idle from cold to warmed up. If I make a pass with it cold and turn around and hot lap, I gain close to a 1/10th in the 1/4 mile. Normally, I make it a point to warm it in the staging lanes before making a pass. No thermostat.

Exactly, That's why a wise bracket racer monitors oil temp.

I think I could stand to drop down a weight in oil. Running Brad Penn 10w40 now...
