Outlaw wanted to know the outlet pressure of the fuel pump. I did not know, so I ordered a 0-60 psi fuel pressure gauge. When it arrived, I put it at the inlet of the fuel pressure regulator at the front of the engine. I got 28 psi, which had no meaning to me at the time. I had always thought it was around 17 psi. I was remembering the old BG 400 system from the last car.
The reason for the high pressure out of the pump is to overcome the high backwards pressure from launch that would slow down the flow of fuel from the tank be located in the rear of the car. This is why many very fast cars that leave real hard, have their fuel tanks and fuel pumps located the the front of the carburetor(s).
This car has a Magna-Fuel 500 fuel pump with filter and by-pass built into it. The factory setting is 28 psi. So, I am right where I need to be, both out of the pump and out of the regulator. The regulator outlet pressure is set at 7.5 psi to the carburetor. PHOTOS
I also changed the oil. I am going with Lucus 15W-50 non-synthetic. I am adding one qt. of Lucius Oil Treatment to the 5 qts. of regular oil. This is due to the high amount the gasoline that went into the cylinders and oil pan when the carburetor was dumping gas.
Last but not least, while looking around under the car after the oil change, I noticed a flat spot on a front tire. Cords were showing. The other tire had the same flat spot and exposed cords.
What is really something (blessing) is; just before I saw the flat spots, I had just said a prayer for Outlaw to be safe while driving at the track! Nothing but Jesus could have made me look at that tire…
These tires are about 2 years old. Outlaw had to avoid a car at the top end, that cut across him and hit the wall a few months ago. This is most likely where those flat spots came from.
This just tells me that I need to pay more attention to the front tires. A blow-out at 150 MPH, at the top end, might have been tragic. I ordered two new tires today.
