I thought this might be a good thread for people out there trying to get the most out of their e85 tune.

I will start:

3650 lb car w/ driver
131.5 trap speed
11.2 a/f
22 degrees of timing
25 creeping to 26 lbs of boost
6768 turbo, 234" engine
th200 4r trans
2 walbro 307's w/relief pushed in
160# injectors
58% duty cycle
stock fuel rail
-10 feed
stock feed line used as return

No signs of detonation on pump grade e85 that tested at 86% according to my test tube tester.
 
Afr for gas and e85 are not the same. and if you do get lets say e70 it will be richer than e85. so thats why you should aways tune in lamda. same for all fuels.

You mean lambda? The a/f I posted is the gas scale, which is what my ecu converts the lambda reading into. Its an older system that can not be changed to show a scale for e85. I use the gas scale because it seems to be the universal scale everyone seems to use on the internet. 1.0 lambda is stoich no matter what fuel you run. So, if I have e70, e85, c16 or whatever in the car it will have the same lambda number from what I understand. The a/f ratio is just a converted number from the lambda number. What's the difference then if I say im running 11.2 on the gas scale, 7.1 on the e85 scale or .82 lambda? Those numbers may not all equal each other, I just was using it as an example.

Very funny buddy, so gabby did your motor with my same parts huh? And you went 143 mph with a te61... Your full of crap , I actually have videos of my car with that setup your mocking . Lets meet at palm beach at lock up something tough guy.
 
Yeah 143 in a full weight Buick v6 with one 61? Where's the bs flag or where's the rest of the story?

Hahaha who says it's full weight? The things you guys talk about and don't know a damn thing about. Btw, your numbers are PARKED

Yeah you must be at 2000lbs.
Is this a single te61? Is it a 86-87 turbo Buick? Tell us what you have. If its a 3300lb + regal with a buick v6 with all the above I call bs. Te61 on 21 psi?
 
Kevin come on dude, you can't be serous believing or trying get a true story from this troll, the guy only has 2 posts and pretty much copy and paste's my build and says he knows Gab, he's a jealous prick that has nothing else better to do other than talk crap cuz his cars slow, that is even if he has a turbo Buick.
