E85 results

Any idea how much rwhp the E85 upgrade (alone) made?

Im not sure as we use the driving to tune and the track for dialing in data. As far as ETs i haven't had the trans and other issues dialed in to see lower ET's, but i can you tell you there is no doubt a nice feel of power behind the car now.

Not to take this off subject, but it would be interesting to see a UOA, "used oil analysis" from one of you guys running 100% E85.

Terry Dyson from Dyson Analysis is seeing great results on a few of his customers running E85. The major benefit is a cleaner burning engine. I wish I could get it around here. I would run it even in my 02 Silverado.

Well I can tell you from my personal experience that you will burn MORE than 30% fuel compared to 93. If the old mileage computer if is correct on my 2010 I get an average of about 6.5 MPG on E85.

Of course i have a triple FORE system and run about 21 pounds of boost which results in 1015 RWHP so to me, I am happy with that. Having said that, I didnt expect the mileage to be that low but I just dont give a shit frankly.

We were debating on using a dual or triple pump system but at these power levels using E85, it is a requirement. ON the good side of this I am able to safely run 18 degrees of timing but I also have methanol injection that helps with that as well.

Your tune might be perfect for max hp on the DYNO with good afr readings, but it's not correct for daily driving in the 1,700 to 2,200 rpm range if you are only getting 6 to 9 mpg, I'm making right at 800rwhp on E85 and was getting 10 mpg and had the cruise area looked at with logs and a timing adjustment was made and now I get 18 mpg, you might log in the low rpm area, I'm sure it will help you.

Is the rest of the stock fuel system satisfactory for e-85?

YMMV. I got +129 with my TT setup tuned yesterday. Still trying to figure out the idle surging but that's another issue altogether (was there before).

No. I wouldn't go that route without a large twin pump setup. I'd honestly be skeptical running the LPE twin pumps where they are only rated for 800hp at the crank, there isn't a lot of room to grow.

With E-85 I'll be close to 800rwhp so that setup wouldn't work for my goals. I went the ZL1 pump route and now I'm having to swap that out for the squash setup.

I've been seeing 85-100rwhp gains on some of the blown cars out here that have to run 91 and make the switch to E85. That is the biggest reason I'm making the switch. That and it's almost half the price of crap 91 here.

The reason you can get more power from running e85 vs 93 or 91 gas is because you can run more timing with e85. With an 11.3 to 1 compression motor and 21 pounds of boost I can still run 18 degrees of timing On 93 octane you would have to run at least 10 degrees less timing. So that would probably mean 80 to 100 hp Less than the E85 combination

I will say though than E85 cars are much harder to start once the air temps get below 45 degrees. I would never run e85 if I lived up north. Lol

I upgraded the plugs, spark plug wires and ignition coils since I'm in kansas and it help cold weather starting a lot this past year, the year before it was hard starting in cold weather for sure.

Well, that's interesting. Never heard that one before. I live up in WI and a lot of our spring and fall "test days" at the drag strip are in the 40's. Can anyone else confirm the "hard starting" issue with E85. Obviously I don't drive it in the winter, but I still don't want to worry about any potential issues.

[swiftkart]

You will not notice a difference at 40 deg, not until you get down to 10 or so I'm talking real winter weather and why do you think the winter blend is E70 vs summer E85, for better cold starting they add 15% more gas and less ethanol becuase gas ignites better, a quick search will show you there can be cold starting issues, its not as bad as you are thinking, but it does get worst when the temps drop.

who tunes for you swift??

Flex fuel makes a lot of this no issue. Gets cold, run 91-93, or just blend it. Car will automatically adjust for 0-100%. No worries about if it is e70 or e85, or e10. Just fill up and enjoy.
