Really appreciate the feedback. Thank you. I currently run gas and I am moving my CR up to 13.5 to 1. It was pretty low before 10.6. I was considering trying E85 and was interested in what other people have got up to in CR using it.
Originally posted by SR6223 Monza: BG77 I am sorry I misread about CR I should have caught that . My motors are 13.9 & 14.1 and I haven't had any issues.
Not a problem at all and I appreciate the feedback. Sounds like it can be a great cost savings if you can find true 85. If going to drums it sounds like 6 of one have a dozen of the other. For consistency it sounds like reported improvements by many but I understand the tune plug combo can be touchy. Does anyone run any specific pump volume. I dont know if what I have will be sufficient. Just trying to spend my budget wisely. Already into more than I planned for this winter but it is racing so you will have that.
I run a Barry Grant 280 with a rear mounted fuel cell through -10 line to the regulator and a dedicated line to front and rear bowls , with no fuel log with -6 lines. Fuel pressure is @ 6lbs initial and will fall back to 5.5 on the mat. Im sure you have already read a lot of different material on it so I wont bore you with details. It does use about 30% more fuel than race gas.
