I recently had some fuel issues with my Powerlites turbo. My gauge on my fuel regulator was all over the place and I was always wrenching with it. So I did some research and found that it could be shot and its an inexpensive unit. So I went off to the performance parts store with this old one. I ended up leaving with a universal Aeromotive fuel regulator, with the boost nipple. and 4 open upper ports and a dump in the bottom. As I really never new much about these, I relied on the parts person who was quite knowledgeable with these products. I got a fuel pressure gauge, 3 nipples - one for each site and one for the fuel return line and a plug for the back.
So from the MSD fuel pump I ran it to the one side of the regulator and the other side to the fuel rail, then the plug is in the back and the gauge is in the front. The bottom runs back into the tank. I changed the spring as noted in the instructions for higher pressure. So I ran this, set the pressure at 46, and it ran a bit rich to start, so I turned it up to 49 PSI, my air fuel was between 11.2 and 13.1 and when applying the fuel and a good rate my a/f is at 12.2 to 12.5, which im told is good. The only issue I ran into is when I went back to idle it needed some more fuel, so I turned it up to 50 psi, then its was great all day, went through a tank of fuel and the sled never ran this good, with good numbers and the bog and grunt I had before is gone. It started easy and worked good. Then the next day im looking at my old regulator bracket and it says 2:1, the new one is 1:1, so I phone Dave for some advise and he says if its working good id leave it. If I put a 2:1 on now it would have higher numbers and thats not what I want. This was tested on rolling hills and not in the mountains, and im hoping It works good there. Will it? Or should I be looking for a 2:1, Ive now seen some switch to this and it works great. Any one else change theres?
