Minimum staging oil temp

with aluminum block and rods ruining .00045" clearances on rods and mains also using brad penn nitro 70 et what would be the minimum staging oil temp?

 

That seems tight on the rod clearance. Temp doesn't matter on a blown app. It's gets hot no matter what. After a burnout is plenty of oil temp. Why are you asking?

 

we have always run an oil heater in the tank. We have the oil up to 130-150 everytime before we crank the engine. We run LUCAS 70WT and have been very happy with it. I have spoken to a couple of people at Oil companies whos job it is to know , they all tell you warm oil works far better than cold oil. Have it warm before any RPM is put on the motor.

 

Good advice.

 

i know warm oil lubricates better than cold and aluminum rods are less brittle with some heat in them just curious what temp the majority of you guys stage at , and my clearances might seem tight but once warm with all aluminum probably a lot looser at operating temp? Just curious what most guys are staging their cars at?

 

I'm hoping you just typed an extra 0 in for your rod clearance, otherwise you should be running Pro Stock oil in there instead of 70wt.

But yes, warm oil lubricates better because the viscosity is a little thinner and can get to all the nooks and crannies with tight clearances and allows more volume to flow at higher velocities at any given pressure. Synthetics/blends usually don't thicken up like traditional base oils because there are less natural parrafins in the base oil to help thicken it, so there can be less difference between hot and cold pressure.

Never really used a temp gauge on the oil, but I know after the burnout the return line is typically lukewarm to hot, so probably in the 110-130 degree range. Unless the ambient temp is in the low 60's or less, never really worried about pre-heating the oil for startup since we've always pre-lubed everything while assembling and servicing. Just depends on how it poured into the tank on whether we heated it. Start and idle, maybe trim the fuel shutoff to get heads and oil up to temp before introducing any throttle.
