Was just watching the races I recorded from yesterday and usually freeze frame different parts of the runs or cockpit shots like I just did on Erica`s car and the oil pressure is about 10 lbs. at a 1900 rpm idle. That totally goes against what we usually tell ourselves or others and most cringe at 20-30 at idle.............. shruggy

Maybe that low so it won't be too high at the 10500 redline. These engines do not sit and idle like a daily driver car.

A.J's MPH is starting to step up and that's a real good sign.

Nothing unusual for most any non blown heads up deal. Especially with 0W5 or the typical 0W10 oils they use. Mine is at 20-25 at idle. Biggest issue with light oils are valvetrain/spring problems.

He had a slightly higher MPH than Anderson today, but Anderson may have hossed the gas on him. It did look like Allen's car spun right at the hit too.

They will only have 40 pounds at 10,000 too. You can turn a fully assembled ps short Block by hand using the balancer lol....amazing to me.

I don't know if it's true or not, but I was once told that an old superstock trick was draining the oil and running it, less windage I suppose but bye bye motor. Maybe someone else could confirm or deny that?

Back before synthetics came around Lyn Smith told me you wanted just enough oil in the motor so the pressure just dropped to 0 at the stripe. He would run 3 quarts on heads-up runs.

3 quarts maybe but no oil wouldn`t fly I would think.......

I wonder how many bearings got scorched before figuring out the minimum he could get by with?

Had an Indy oil pump seize up on a new engine start up. it was idling nicely at 1200 rpm, almost dies when the pump seized, and then sped up to 2000 rpm when it was no longer turning the pump. amazing how much power the oil pump takes to run.

I seen the oil pressure also. I thought it was 0 though. I was waiting for it to go boom on the pass,

IMO any max effort N/A program from stock to pro stock should only have minimum oil pressure, minimum oil flow, minimum oil cSt, & minimum bearing surface areas to do the job.

Been as low as 35 lbs. @ 8500 rpm in a wet sump super stock.

That was common on both SS and modified Chevy racers shruggy I never heard of any BB Mopar racers doing that work I did have one of the better SO CA dyno shops make a comment on loosing HP by adding one aditional quart of oil one of my 440 motors I was dynoing there and they where shocked when adding the fifth quart didn't make any measureable differences in torque or HP on that motor work They did a lot of dynoing NHRA Chevy and Ford class motors, SS, Comp and blown alcholol motors shruggy They did share that using the zero weight Royal Purple synthetiic oils in a N/A Comp eliminator motor was good for one pass only, those motors would run faster the first pass on that oil and break on the second pass if you didn't change it shock That was back in the late 1990s and early 2000s shruggyMaybe things are better now with those type oils shruggy

Thumper
Back in early 70's Gene Snow ran a funny car and Wolf's head Racing Oil ran an add in National Dragster and several magazines at the time. Stating he drained the oil to change it, but forgot to put the new oil in to complete the change. Then he made a full run down the track as I remember it and had no issues when he pulled it apart back in the pits. Not sure if it was true or not, but he swore by it.

If you think about it a garden hose is nominally about 25-30PSI, if you have sufficient volume of a thin oil I see not much issue of a motor living on fairly low pressures compared to old school 30/40/50 weight standards.

I remember that Gene Snow ad....heck, Wolfs Head had enough Pennsylvania Parrafin wax in it the bearings couldn't spin if the motor sat after the run for 40 years!

That`s crazy and maybe the bearings/motor was treated somehow cos Bob Pettis told me years ago that the family was coming back from up north and he lost oil pressure many miles from home. He figured screw it and if it blows oh well which it made it back home and they pulled it down for inspection, and it was in good shape considering. His tried n true trick is Pro-blend which is where he gives credit and it apparently coats the vital areas w/something special and actually worked............

That's because of the skirted block. The windage is horrific in a non dry sump skirted block with a little oil or a lot of oil, so it didn't matter
