Looking for some fact based opinions here. I plan on running 116 octane at the track at around 26# boost, mid 20's on timing. Heading to the chassis dyno soon and plan on doing a strip and street tune. What I'm wanting to do is run a 93 and E85 mix for the street so I can run more than 16#'s with the timing around 18*. Just looking for less of a wimpy street tune and not burn $12 a gallon 116 or mix it w/ 93 for that matter. I like the feel of the car on the street at 20-22#'s and 18-20* timing on 100 octane, 11.8 a/f. Please keep in mind I want to be safe here and have absolutely no detonation. Currently no knock retard on the tune above.
Here is the set up.
Stock fuel lines, adjustable regulator, 255 lph pump, hot wired, 60# injectors, TT chip v6.xx wideband, power logger, AEM wideband o2, Bison turbo (basically a TA60), rpm won't exceed 5k.
Thinking run 25% E85, 75% 93, to raise octane to 96 or so......
Can my fuel system keep up?
Concerns on rubber fuel line components?
Can I run more than 25% E85?
If this is possible start the a/f ratio around 10.5?
Or is this a totally bad idea, and I should live with a super safe tune on the street?
All comments welcome! Thanks, Jeremy.
