As you may remember= , a couple of weeks ago I lost most oil pressure.  I dropped the pan a= nd found the problem.  I safety wired the&n= bsp;culprit up and put my engine back together and ba= ck on the back of the Velocity and cranked her up and got signifi= cant oil pressure as expected.  I could see it pumping freely out a ho= se I left open when I cranked the starter with pumps/coils/injectors off earlier.
=0A
 
=0A
Now, my = question is, what is considered correct oil pressure at different power set= tings?  Before when I ran the engine at idle (on my engine, usually 15= 00 - 1650 rpm, my oil pressure would be around 33-35 psi.  I remember = this cuz,= on my EM2 it is preset to start flashing an alert if the oil pressure goes bel= ow 35 psi, so I was always bumping up the idle a bit to keep it from flashi= ng the alert.
=0A
 
=0A
Now, however, it seems that = at about the same RPM I am getting only about 30 ish PSI at the same RPM a= nd have to rev up to about 2200 rpm to get the pressure to 35 or above.&nbs= p; IIRC, = when I apply power to about 6200 rpm the pressure goes up to the mid 5= 0's or a = little more...maybe hitting 60.
=0A
 
=0A
I had thou= ght I read somewhere that the EM2 was set to alert on oil at 30, but Tracy has = had my unit a couple/few times, so I am thinking the 35 must be c= orrect for low pressure.

It does seem I have mostly got= ten my hot start process worked out.  No prime, mixture at about 2:30 = and a few rotations it sputters alive.  I think I had been flooding it= before.  I also have to turn off the fans as the extra energy seems t= o be needed to get it to spark up.  I do think I need to replace my ba= tteries as I have kinda beat the hell out of these two.  Cold start has ne= ver been much of a problem.  Usually 4-6 primes and a bit of mixture a= dvance and it is usually good, throttle about half way open, then pull back= to idle once it engages.
=0A
 
=0A
Perhaps I am killing the engine now with the different oil press= ure, (new filter, new oil) but the engine seems to be running damn strong o= therwise.  Pretty cool now that the temps are only in the low 90's.  I can= bring power up for much longer now that ramp temps are not in the 120's.
