87sheerips Posted May 8, 2007 Report Posted May 8, 2007 Well im guna sound cheap, but gas is a minumum of 3.20 a gallon here in MI. Anyway, im at a lil over 160 in each cylinder, at +4 timing. I have run 50/50 93/110 since i bumped the timing. I guess it would be a matter of testing, but i dont want to blow her up because of detonation. Think i have to stay with 50/50 or could I run just 93 or 94 octane. Let me know what u think, and sorry i know this has been discussed a bagillllion times Quote
CRAZY-SHEE! Posted May 8, 2007 Report Posted May 8, 2007 well, actually with 160 you should be safe with just running premium pump gas.. at least.. IMO. Quote
Bansh-eman Posted May 8, 2007 Report Posted May 8, 2007 you wont catch me running pump at 160... let me know how it works out for you... id rather spend the extra few bucks and have the peace of mind... Quote
fastrthnu Posted May 8, 2007 Report Posted May 8, 2007 I was always told that 150-155 was the borderline. So thats cutting it close. Quote
Washburn Posted May 8, 2007 Report Posted May 8, 2007 I would atLEAST run a 25-75 or go to a small airport and buy AV gas and run that straight. Detonation is not hard to hear but a little detonation here a little there (Rattle crrrrrakakaka tsssss ping crinkcrinkcrakakakaha) and you need a new motor. Better safe than sorry or go up a size on your domes and that would suck! Quote
dajogejr Posted May 8, 2007 Report Posted May 8, 2007 25/75 or 50/50 will be safe. You might be able to run 92 or 94 octane pump gas IF you put the timing back at 0...but why??? You can try pump gas....but you better be sure your jetting is spot on, keep an eye on those plugs AND listen to the motor.... I'd rather be safe myself.... Quote
Leadfoot350 Posted May 9, 2007 Report Posted May 9, 2007 I would try one gallon race and fill the rest of the container up with the highest pump. My container usually holds about 6 gallons. If you do that with 93 octaine and 110 race that will give you 95.8333333. That will work for sure. Quote
wheatez Posted May 9, 2007 Report Posted May 9, 2007 i would run AV fuel if i were u.. Just check all the airports around u.. u can usually get a decent deal on it Quote
87sheerips Posted May 10, 2007 Author Report Posted May 10, 2007 thanks for all the suggestions boys, but i think ill stick with the ole turbo blue and 93 50/50. Its just sucks when i go to the UP and have to worry about carting race fuel around! Quote
jlsparky7 Posted May 10, 2007 Report Posted May 10, 2007 Drop the timming and run 94. Then you have the peice of mind and you dont have to spend all the money and gas as well as hauling it along Quote
