Hey Chris,
We briefly met at TT. I was running Razor's PAC system then, but had many other problems, so I didn't get to REALLY test it.
I recently took my '87 GN to the track in Medford and ran consistent mid to low 12's with a best of 12.2 @ 112 mph.
I'm set up with a TE44, 3"THDP, 36# injectors, Powerplate, 9" K&N, 2,800 stall 12", denatured alky, and a Casper's Thumbwheel chip tweaked for the alky setup.
I was running 23#s of boost w/ 2 gallons of 110 and 6 gallons of 92. Not bad for an engine w/ 152,000 original miles. I hear about people running 25+ #s w/ just pump gas, but I can't get near that w/o more octane. Tired engine w/ lots of carbon build up probably part of the problem.
I think Razor's kit is very nice, and I'm confident that I'll be able to see those higher boost levels after the upcoming overhaul.
You can save a some $ on the kit by buying your own pump from Northern and buying your own hoses. However, the PAC unit is a must in my opinion.
