FP ? I was wondering this just now what if I just set my fpr to 60psi and dont hook up the boost ref. Will I still have enough fuel for 7psi with spikes up to 9 on shifts? I have #42 lb injectors with the incon supplied intank pump. Till I get a new FPR atleast.

Re: FP ? Assuming you start out at 60 psi and have 9 psi boost with no boost reference then 51 psi fuel pressure at full boost would get you 650 fwhp at 100% duty cycle with the 42 lb injectors.
I guess you still have your aeromotive hooked up to the boost/vacuum line instead of the just boost (you could put a vacuum regulaotr on the line and get 1:1 instead of 2 or 3:1 like your getting). Of course with just boost reference it does not really rise anyway.

Re: FP ? Here's one guy's spin:
"Obviously, another factor to consider in this discussion is how accurately the manufacturers rate their own engines. It's hard to believe that the Corvette and Neon could lose 17 and 22 percent of their engine's horsepower in just frictional losses. Most experts agree that a 10 to 15 percent loss is normal. This does not necessarily mean that the manufacturers are lying. The additional drop could come from a number of causes including variations in engine performance and dynamometer readings. It could also be that the manufacturers are dealing with an expertly tuned engine's running under controlled conditions in a laboratory rather than a mass-produced engine that was put together on an assembly line and sold at a dealer's lot."
