No no noooo! Sickly, don't make me use auto math or I will be at 944 hp or better We did 644 with a glitch in the propane system. I went from 515 on diesel to 581 with lpg. That's about 40 ponys shy of normal. I filled the tank Sunday morning and maybe I should have perged it to get the air out. I'll work the bugs out of the propane system and turn the twins up for May Madness.

Well, 644 isn't over 650

so my overvalved cousin is struggling with propane, nitrous, and twin turbos. That very trying 44 pump, even with multiple boxes and reprogramming, just won't do what the mighty P7100 does (so easily?--easier said than done!)
644-609=35 hp extra with all that junk

609-515=94 hp advantage to the real deal, the P7100

HVAC, maybe it's time you left the dark side and put a real pump on your overvalved engine. That'd fix your rpm problem too

Then all you would need is the real head. Get rid of those Briggs&Stratton sized valves!
12 valves rule!
Time to sneak back to my side
