As you may remember, a couple of = weeks ago I lost most oil pressure.  I dropped the pan and found the p= roblem.  I safety wired the culprit up and put my engine back together and back on the = ;back of the Velocity and cranked her up and got significant oil press= ure as expected.  I could see it pumping freely out a hose I left= open when I cranked the starter with pumps/coils/injectors off earlier.

Now, my question is, w= hat is considered correct oil pressure at different power settings?  B= efore when I ran the engine at idle (on my engine, usually 1500 - 1650 rpm,= my oil pressure would be around 33-35 psi.  I remember this cuz, on my EM= 2 it is p= reset to start flashing an alert if the oil pressure goes below 35 psi, so = I was always bumping up the idle a bit to keep it from flashing the alert.<= /DIV>=0A
 
=0A
Now, however, it seems that at about the s= ame RPM I am getting only about 30 ish PSI at the same RPM and have to rev= up to about 2200 rpm to get the pressure to 35 or above.  IIRC, when I apply = power to about 6200 rpm the pressure goes up to the mid 50's or a little more..= .maybe hitting 60.

I had thought I read so= mewhere 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 correct for lo= w pressure.

It does seem I have mostly gotten my hot st= art process worked out.  No prime, mixture at about 2:30 and a few rot= ations it sputters alive.  I think I had been flooding it before. = ; I also have to turn off the fans as the extra energy seems to be needed t= o get it to spark up.  I do think I need to replace my batteries as I = have kinda beat the hell out of these two.  Cold start has never been much= of a problem.  Usually 4-6 primes and a bit of mixture advance and it= is usually good, throttle about half way open, then pull back to idle once= it engages.

Perhaps=  I am killing the engine now with the different oil pressure, (new fil= ter, new oil) but the engine seems to be running damn strong otherwise.&nbs= p; 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.
