2sTrokeLove Posted March 13, 2014 Author Report Posted March 13, 2014 Trying to get close on my jetting also... Quote
2sTrokeLove Posted March 13, 2014 Author Report Posted March 13, 2014 (edited) He just suggested that when I did call him and talked with him. He wasn't the builder, that's why I did call him. I was just curious if I could even run premium at all but ok guess this site isn't for asking questions, just for assholes like you to fuck up every thread you can like normal.... But typical coming from you thanks. Edited March 13, 2014 by 2sTrokeLove Quote
swhitey917 Posted March 13, 2014 Report Posted March 13, 2014 Jeff knows his shit. I would stick to his recommendations and ask his advice for what is needed to get away with lesser grade fuel. If it was me, I would stick with the +7 and 110 fuel. Quote
2sTrokeLove Posted March 13, 2014 Author Report Posted March 13, 2014 It's already to go with the 7 and 110 I was just curious on the premium but I'm a moron for asking on here... Quote
2sTrokeLove Posted March 13, 2014 Author Report Posted March 13, 2014 Was it that big of a deal to ask about premium fuel from someone else's view? Just thought I could get good opinions from previous experiences.... Quote
locogato11283 Posted March 13, 2014 Report Posted March 13, 2014 Who is the builder of the motor? Who did the clean up? Who did you buy it from? Quote
2sTrokeLove Posted March 13, 2014 Author Report Posted March 13, 2014 Bought it from pastrykiller, he said it was cleaned up by cam at redline. I called and talked with Jeff and got domes and other parts that he suggested I just wanted to see if it was possible to get away with premium with my compression. I'll just give him another call. Didn't think it would hurt to ask on here to see what others thought. Quote
Deadbeat Posted March 13, 2014 Report Posted March 13, 2014 why not just run it at +7 and 110 for a while...if your that desperate to detune it and save money using 93oct do it later Quote
2sTrokeLove Posted March 13, 2014 Author Report Posted March 13, 2014 I am going to, just have to travel a bit to get the 110. I was only curious if I could get away with premium. Quote
Deadbeat Posted March 13, 2014 Report Posted March 13, 2014 quite a few peeps are running 160ish comp on 93 but its the ragged edge, maybe start with 0 timing then bring it up, doesnt take much deto to suck months/years of life out of your bottom end Quote
2sTrokeLove Posted March 13, 2014 Author Report Posted March 13, 2014 Ok thanks, I'll run this and see how she does, and if I need pump domes I'll hit Jeff up again. Quote
