Anyone have a e85 n/a Before and After dyno sheet Looking for a Before and After e85 dyno sheet showing the gains on a na set-up.
I've been hearing a lot of good thing about switching over to e85.
Just looking to view a few dyno sheets.
How much compression can it support na?

I think I do remember a stock LS2 vette that they converted to e85 with no other changes ended up gaining about 15 rwhp.
The biggest hassle with e85 in a DD is availability.. AND you need to carry a tester to make sure the blend is right. There are 3 e85 blends and if you run the low blend on a high blend tune it's like putting 87 octane in and you'll blow your **** up.

My tune is 3 weeks out. Pushing the stock bottom end limits with ptv and fly cut depth, sitting at 12-1. It will also be an SD tune. I'll post the dyno sheeet when it's done.

I may look into this now. i only drive my t.a on weekends and e85 is right down the road 1mi from my place.
SLICKVERT-Is the only way to know the quality of fuel is to test it? they don't tell the rating on the e85 pump?

from tuned on gas to tuned on e85 the gains are minimal, 4-6 hp at peak and 6-9 ft lbs. I have done it a couple hundred times. It doesnt matter what the blend is (again done this MANY times) N/A is minimal gains, large vs. pump gas on forced induction. We have run alot of motors north of 13:1, up to 16:1 actually, although that is the limit (14.5ish would be about the edge of comfort)

And it absolutely DOES matter what the blend is. It's the reason some tuners won't tune e85. In fact a sponsor here told me that they won't do it because those guys blowing up their cars without testing the blend will reflect bad on their business.

When your choices are much more expensive 100+ octane or having to lower your compression and timing for 93 on a N/A car, e85 is worth more than 4-6 and 6-9

No, it really DOESNT matter (very little anyway) what the blend is. I have guys running low 8s for 3 plus YEARS on PUMP E85 (they dont even check it any more) I've made over 1500 to the tire with multiple cars for a number of years now (started getting popular in 2007) If you run the ragged edge with your tune up you can blow **** up, I dont care what fuel you run. A good tuner that has experience with e85 will tell you the same, not someone who reads the internet. I've run 30-40 plus pounds of boost of big dollar engines and dont think twice about getting fuel from the same gas station I've been buying it from since I started playing with it in 2005-6. I have tested specific gravity, tested with the kent-moore tool I own (since 07) and sent it in for lab testing as well.
If you want real world results and not theory, this is what I have experienced time and time again. If you have a car that it would make a difference on, I would suspect you would not be calling a tuner that was a sponsor, you would ask your crew chief of your top fuel program. There is differences in the blend, but not relavant at the level 98% of the people of this website are at.

I believe OP asked a comparo vs pump gas, and I stand by my statements. If it is high compression (above 11.8-12 or so) the gains go up in an exponential manner.

I'm in south Dakota. I have spent quite a bit of time in Illinois with our dyno, as well as spent time on other dynos in illinois doing dyno tuning for people that had us come to tune as well as 5.o mustang magazine tech article done at Anderson ford. E70 is still 101 octane... If you blow your **** up by changing blends on an n/a motor, you should find a different tuner.

IMO you cant beat 105octane fuel for $2.19 a gallon. and if you're worried about winter blends my suggestion is buy a winter beater and keep the hot rod out of the snow since the tracks are closed anyway.

Thanks for all the good info. I have a few more questions
Where can I get a kit to test e85 octane?
Do you need to change to a different heat range spark plug?
Is there a way to increase the octane of the fuel for safety for those with high compression?

I apologize and retract my info as related to a 12-1 N/A 346. You are right about the E70.
