93 vs E85 60-100

Just made a video to show the difference between 93 and E85.

not too bad, thought maybe youd get a little more but it is quite noticeable.

Thanks, I was thinking of asking Vince to make it more aggressive. But since the wife gave me the ok to go big turbo (ZZP EFR) I'll leave it alone

night and day difference for me(supercharged).... i broke loose at 70mph getting into 3rd for the first time after switching over. although i did go from gms2 to 2.8", 80s, and e85, so there was a lot more of a difference. definitely worth it.

You typically log about 55 to 100 so you can time the actual 60-100 time with you at full throttle the entire time. I get too much tire spin at a 50mph 3rd gear roll to get a good 60-100.
If you look at it your actually slower on the E85 run than the 93.... i timed almost a 7 sec 60-100 on the e using pause/play timer

the reason i started at 50 was i wanted to be at full throtle and at the full 24 psi. by the time i hit 60

I did the same thing... ~6 seconds on 93 and ~5 seconds on E. Checks out to me for what the OP has listed of the 5.8 and the 5.2 respectively.

What are you on for E? Is this a 50/50 E85/93 tune? Is this just pure E85?

What all do you have to change up to run 100% E85? Just the tune?

I was going to post in Vince's 100% E85 thread, but for some reason my phone won't pull it up

Tune should do it.

Some have ran into fueling issues if you have a ton of mods.

Can also run a 50/50 mix or just about any other mixture of the two.

Would the E85 tune, charge pipes, intake, aftermarket intercooler, downpipe, and exhaust cause fuel issues you think?

Will do bro, so far I do run into the low pressure fuel rail above 120 but only when it wants to. There have been time where it doesnt come on and others where it does?? That has me baffled.... Guess it depends on whether it's a bad batch of E or not?? Really don't know why it does what it doesn't ????

I'd maybe talk to Vince about the problem over 120, but atleast it's at 120+ so it doesn't really affect quarter mile times or anything
