oil pressure drops at topend of the track
I ran my car for the first time this year on Friday. I saw the oil pressure was down to about 15 to 20 psi as I crossed the finish line at a little over 6,000 rpm (I shift at 6500}Idle oil pressure is fine as well as driving around the pits. I changed the oil before racing since the car has set all winter with 20W50 VR1 and a wix oil filter. I also noticed when I let off pass the finish line it took a second to return to normal pressure. Do I need to worry about this or could it be a gauge problem? The motor is a 12.6 to 1 383 sbc with Eagle 4340 rotating assembly Dart pro 1 heads and a solid flat tapped cam with a high volume oil pump (not a melling I think its a speed pro). The motor has been together for about 7 years but has not been ran very much. The motor has a 7qt pan with trap doors in and I am running the 1/8 mi. any ideas?
