well i installed a aeromotive adjustable regulator on my car a couple weeks ago but i didnt have a gauge to read the pressure. so a friend of mine let me borrow his auto meter 1.5" gauge and fitting that screws on to the rail. we played with the pressure and ended up leaving it at 46, thinking this was more then enough. well i took the car to the track and ended up blowing the head gasket, i was baffled, i was running less timing, more fuel and an ic fan, i figured this all added up to a less potential for detonation. at the track it detonated bad but before i could let off the head gasket blew out. i figured i must have had just too much timing and the fact that there was 131k on the engine. but today i stumbled across the real reason i was having problems. i went ou tand bought my own 1.5" gauge so i could give my friend his back, well before i took his off i checked my pressure and it was at 46 static just like i had left it, then i put my new one on, and whatta ya know it read 30 static, i then realized my friends gauge wasnt even reading 0 when it was off the car, it started to make sense, i had set my FP to what i thought was 46psi when it was only 30psi, OUCH! i then set the pressure to 43psi according to the new gauge and took the car for a spin, wow, it runs mint now, no hesitation, detonation or lack of power. im kinda pissed that i lost a head gasket due to a faulty gauge and i missed out on fun ford weekend, but i guess it was good it rained today cause i was gonna go back up and try again, but instead i decided to put my new gauge on. anyhow sorry for the long post but i figured id share my experience with you guys, maybe this is the reason for the other threads on here where people are getting lots of detonation thinkin they are running good FP, everyone check your stuff! a head gasket is bad but a melted piston would be worse. just lookin out for you all.
