VP Q16 ?
are all the internet post about the Q16 true or bull about the up to 30 Hp gains. in other words has anyone here ever tried it and proved it to be a Plus or no not. I'm running 15.33 to 1 Compression in a 434 with 230 Dart heads and 950 ultra H/P now it's running 670 Hp. I tried the 110 octane Vp oxigenated. and it made no changes. then the man tells me it was because I needed the 116 Octane because of my compression ratio. I'd like to know if anyone has tried it before I go spend $65.00 on fuel that I don't need.
Thanks Andy
