[quote=“turbo329is” post=58544]I installed the exact same setup except I have a 90deg AN to NPT adapter instead of the VAC block and got it calibrated at autobahn cc south. The pressure seemed to be reading correctly sitting in the paddock. Idle with cold oil sunday morning was 65 and dropped down to about 23 when it warmed up. The oil light only ever came on before when the idle dropped down to around 500rpm. Sunday morning my light came on nearly every corner right and left and according to the datalog dropped to 7psi on corner 3 (high rpm left). I have a stock pan with a crank scraper from IE and an oil pump that looks like it was used to grind rocks. I used 0 ohms equals 0 psi and 180 ohms equals 100 psi and let the datalink software figure out the rest.
Do I need to bleed the oil line? I figured air can carry the pressure to the sender decently enuogh.
How high on the dipstick is a quart high? I was right around the full line.
I think Jim Levie had previously mentioned drilling out the orifice of the pressure sender. Would that make any difference.[/quote]
It doesn’t sound like you have a calibration problem, but more like an oil pressure problem. Drilling the orifice like Jim suggested will make your sender respond faster. Because you are seeing pressure drops in corners, your sender is plenty responsive.
Your symptoms are indicative of a tired motor with loose rod bearing and possibly main bearing clearances. Also, the IE scraper isn’t enough. You need some sort of baffle to keep oil from climbing out of the pan on hard left handers. Both Metric Mechanic and TC Motorsports have good solutions.
