Guesses as to what it makes!
It’s finally about time to take my car in to convert to e85! I have had a fuel sending unit issue since I bought the car so while I am replacing the sending units I figured it would be a good time to take advantage of some e85! Curious as to what you guys think I will pick up?
Currently the car makes 555/508 on one dyno and 579/528 on another, the car was tuned on the lower number dyno and will be going back to that same dyno. Those numbers were made on 93 octane. BTR Stage 3 Heads milled .030 Melrose 1 7/8” with Hi Flow Cats B&B PRT Halltech MF 103 NW 102 Mamo MSD Walbro 450 FIC 850’s DSX Flex Fuel Kit When the car was tuned, he said that he did see some knock with 93 so hopefully this turns out to be beneficial! |
I’m going to guess u pick up 20rwhp and 20rwtq but u were on 93 and looks to be a conservative dyno. So 10/10 but I believe it will make a good difference in the mid range from what I’ve seen |
Depends on how conservative the 93 octane tune was. If they saw knock and pulled some timing you'll pick up more. I'm going to guess on the low end: 10whp/15wtq
|
I’m guessing on the low end as well, then if it picks up more I’ll be pleasantly surprised! He said that he did pull some timing when he saw the knock just to keep it safe.

Can’t argue that:lol: But e85 is half the price of 93 here so it won’t be bad.

I get better mileage on E85 because of the cost. Just have to fill up twice on E85 per 1 tank of 93. If you look at it that way, of course.

Yeah it should end up being close to a wash between the two fuels. Not like most of us really picked these cars for their gas mileage :D

The first dyno with the lower readings is what you want 588 525....the other dyno is reading high looked like std numbers..

Getting over 30mpg on the highway when it was stock was pretty awesome. LOL

Awesome enough to go back to stock? I didn't think so, me either. :D

Hey Jared, looks like your car is coming along nicely! I’m not surprised on the dyno differences, my two baseline dynos were off about the same amount when Mike moved to his new shop. Interested to see your net gains, your plan makes sense. :thumbs:

Good plan Jared, tuned in for results!

I'm running a flex fuel setup on my HCI and did not gain a single horse on peak numbers, gained about 10hp and 20tq through the midrange though. Only difference was my heads were not milled and the sensor was reading only 70% ethanol. Not sure how much difference that makes
