We don't ever end up with the bad winter blend in DFW. I think the worst blends are typically E79/E80 around here. In the summer some were as high as E86 at the Krogers for whatever it's worth.

It does end up having enough power to put the motor in the danger zone even with just the stock turbo especially when tracking, like Shawn said though the torque hit is awesome and the look on the vette and other v8 owners face when they get drug from a roll is priceless.

I concur however that reliability is greater than max hp/tq figures.

 

I think that you'll see more of an improvement than you think, you will pick up more than 20 ft-lbs of torque.. Why don't you just get dual maps for 93 and e85?

 

I am already making ~360tq on my setup with 93. Unless you are suggesting it would be higher than 400tq. I think even the Cobb dyno's are just shy of 400hp/tq numbers with my bolt-ons and e85. I would agree that is approaching more than I want for sustained output. Daily driving looking like a cowboy, I have no interest in. Map switching is great and all but then you have to worry about the switch and running low or priming the rail to get the good stuff flowing. I do most of my autocrossing out at Mineral Wells and finding e85 out there or on the way is doable but finding space in my already filled up trunk and back seat is another issue entirely.

 

For miserable wells, I'd stop at the Grapevine chevy dealer and fill up and fill up 20g of E85. Make the trip out and typically make it home with the 5g of the 20g I bought left over.

Here's my dyno with E85. 400tq/375hp so you can compare under the curve.

a lot of good info here...i was just about to start prepping for E85. but i don't have a ton of extra cash on hand all the time. i might just stay with basic bolt ons for now and just save up for an fp upgrade.

 

Running E85 with map switching really is not a big deal at all.

Just run until the low fuel light comes on, run a little more, then fill up with whichever fuel is available and flip the switch.

It's that easy.

I'm on E85 now and really the only downside is the difficulty of getting it started on cool mornings like today. The upside is that on cool days like today the car runs like an absolute monster! It's even faster than ever.

^+1,

 

meth injection:
meth injection is an alternative alright..however, if you're not going with aquamist systems (HFS3v2, HFS5or6 or whatever is injecting based on IPW), forget about it. Other than those models i wouldn't think about getting any other. found this the hard way just by exploring. another thing is the 100% meth, there a failsafes alright but to be on the safe side, i'd stick with 50-50. i tested and tuned both mixes and i'm sticking with 50-50 it's all in the tune in that side.

e85:
i'm actually thinking of converting to e85. i'm about on the same boat on you on some of the reasons why not to get e85. don't want to carry extra cans behind me as i have a baby too. if you're traveling a lot, not all areas have the same e%. basically like what all Sean said. if tephramod v2 comes out, this wouldn't be much of a problem as tephra is looking into like the ethanol content thing which would automatically switch maps! to be honest when i saw that, i'm thinking of switching over. the only concern left would be the fuel availability , power gain wise, and the hassle of trunk space if you're going to carry cans with you.

 

I have been running E85 for over a year and a half in my car and I love it. My average is about 180-200 miles per tank. Like Sean said above, all of the low end torque is really nice to have, and it is almost on-demand with the stock turbo. The map switch is not a big deal, and if you coordinate your trip properly, you can avoid pump gas. I can go to San Antonio and back on E85 without putting in pump gas and without carrying cans.

I have a stock in tank pump with a surge tank, Walbro 255 external, and FIC 1100 injectors. I don't recommend the pig tails, so that means soldering on the connectors. The piece of mind from the solder is worth it.

If the tune is adjusted properly, the cold starting and running in the winter isn't bad at all. I drove with no problems last winter when it was 15-19 degrees F outside.

 

So, the RX8 had been great other than being low on power? I always thought it would have been a nice car to track being balanced and RWD

 

Does the stock fuel filter also need to be replaced to be E85 friendly? I remember reading goofygrin's post on another thread about the stock paper filter not being E85 compatible

 

IIRC it's the sock on the end of the fuel pump submerged in the fuel tank. There's a hose or two in there that need to be swapped out as well.
