Fuel Numbers for my "Speed Demon" (not)

[PipeDreamsMarine]

Miles... I'd get a good Tach before I'd start playing with wheels. I have a good number of years messing with inboard boats. But it's your choice if you beleive me or not.. But your not turning up to max RPM's (if the new tach is right)with the 17/15 wheel. 1 inch of Diam is 1000 RPMS and 1" of pitch is 500 rpm's. Your at 3800 with the 17/15, knock 1" of Diam. off and your up to 4800 that's about 200 over max for your motor, so add a little cup and it should be just right. The 16/17 is allmost the same wheel, just at lower rpms(idle speed)your gonna move faster. I'd look at a 16/15 with a cup, A case of beer says I hit it right on the money [img]images/icons/shocked.gif[/img]
