How much boost on 110 octane????

[greeneclipse]

whats the max. boost i can run....safely.....on 110 octane with a re-wired stock pump on my 14b??? I have a logger, but no fuel controller.

18psi is squeezing every bit of power the little 14b has and still may be a ineffient at that range. You really shouldnt run over 15 w/o injectors and logger/afc (or dsmlink)...but you can. I ran 18 on my T-25 on stock fuel system... inefficient as all hell but it worked from at 40-80mph.
