No, it's not folk from KY, it's just guys with Eliminators that get the bogus info...

here's the link you need

blown formula, I have the idol pressure set @ 36lbs ( read from liquid filled mechanical gauge on reg.) if I try to run 40lbs or more, the engine floods over and runs rough. How do you run that much pressure? I did have the ECU re-programmed but the injector pulse should only be lengthened on mid range and top end??? Also the boost compensation is on a 1:1 ratio, thats 15lbs. from idol to W.O.T on your set up. How much boost are you running? Are you checking pressure with a mechanical guage or an electrical mounted on the dash? I don't care who makes them, the electrical guages are NOT that accurate ,always off by a few lbs. or more. Your reply is appreciated. Thanks, Frank.

I have the same question about how you can run the base fuel pressure that high. At 38 lbs. I have a black transom and wet plugs. Also, thanks for the link McCollinstn, are you not running any kind of water seperator? Maybe, they consider the Keith Eikert unit high enough flow to suit there specs. By the way I am using a gaffrig electrical fuel guage with the sender on the port of the boost sensitive fuel pressure regulator. Thanks for the help I want to get it right.

blown1500 What kind of spark plugs do you run, stock ACMR-43T's or something colder ? I like to NGK'S 5673-8 in Roots style blower motors with iron heads.

separator AFTER A1000.

Same here seperator AFTER the pump.
I run an idle pressure of about 43 psi, But I had my ECU reprogramed to NOT use the warm up mode as an enrichment. Procharger recomends 35 psi because they know without the stat in place the ECU stays on the warm up mode and makes it rich. Didn't like that set up. Also didn't like running with out a stat, Up here the water doesn't get that warm, and when it does, it's usually late July. So I run a 120° stat with the warm up mode programed for it.

Claude,
Just purchased one of Pro Chargers water temperature signal conditioners. Any ideas how this will effect required fuel pressure? Very rich at idle with 35-38 psi and no conditioner. Anybody use this?

Hum?? Thats new to me Eric. Is it posted on there web site. I went there and couldn't find any info?

the 45# @ idle I run is set with a mechanical gauge @ the fuel rail. There is also electric gauges on the dash.. I am not certain what Arizona Speed did to my ecu, but below 42-45 #, it does not idle well. My transom is still pretty clean even @45#. Better a little extra pressure than run lean when flat out also. Tell me, did either of you guys install EGT sensors & gauges??? If not, I recommend it highly!!
I am, like the others running a "pre-filter" before the pump & a water seperator/filter after. If I knew a year ago what I know now, I'd still have $10 K in my pocket!!

If I understand correctly, the signal conditioner makes the ECU think that the motor is running at full temperature so the rich mode is disabled. This is what allows you guys to run better fuel pressure and have clean pipes.
