A friend of mine is running about 25 pounds boost with E-85 on his Big Block, without an intercooler.
Also, how much of a safe boost increase might E-85 allow on a stock shortblock? With lower combustion temperatures and greater resistance to detonation, I'd think the stock pistons would be less stressed, and there would be less chance of butting the ring end gap. I'd be darned surprised if it wasn't good for another 150 hp. Anyone try to explore the limits with this?

I haven't seen anyone. But I Gurantee you a stock shortblock record could easily be broken with e85. I would bet money with upgraded rod bolts you could have it hold over 1000rwhp for a while. One of the magazine companies just did this with a 5.3 stock short and some eBay twins and made 1200hp. I don't believe it was on e85 though.

I run a non I/C maggie with e85 and haven't really seen the heat soak issues that many complain about with these blowers. On the dyno with no cool down period my numbers varied very little. In fact I put the numbers in my sig down on the 4th pull.

I figure since with the 3.6 liquid cooled KB blower, the e85, and the cooling affects/cold air of the blower sticking up through the hood, if I have any heat issues at all I will just take a sledge hammer to it anyway

Torco worked for me for a year until I wised up and went E85. There isnt even a comparison between the two. If boosted its a no brainer. If you have E85 available and a fuel system to support it then continuing to use Torco or any other octane booster is just.....goober

Thought I'd re-look into E85 after seeing this thread. No go for me though since E85 is only 2 cents cheaper than 93! This is on Ft. Benning, GA BTW and is the only spot around to fill up. Maybe in time though. (Oh I DD my V so mileage is a small concern).

Major downsides are the cost of the fuel system, limited availability, and the need to check on/tweak the tune so often due to the different blends. For me I think it outweighs the pros. I'll do 93+meth most of the time. C16 when I want to crank it up.

right now I been running e85 for almost a year and it is great. No downside other than filling up more frequent. I just ordered the ID2000. Once I install will see what more I make. I was limited to the injector size before I made 650@12-13 psi I am going to try and make 14-15 psi and see if I make it to the 700 club

The only real downside I see there is the availability for some people. Luckily we have 5-6 stations in our town. Fuel system cost isn't much more if any extra than what you have to spend on a meth system for 93 octane. I have a friend who runs the same tune all year with all three level of blends and never touches the tune. Sure it runs a little rich in dead winter, but still much safer of a fuel compared to 93 and meth in my opinion.

I'll be switching to full e85 in about 1-2 months I will post some info. I will be using the stock fuel system minus what comes in the A&A Kit. Just a fun test to see what I can do on eth for the cost of an hour tune. I will likely be maxing my injectors but I dont drive my car much so not too worried about that for now.

Thats ridiculous a station is only that much difference. The Chevron station here E85 (its not Chevron fuel btw) is $3.59 and pump 91 is $3.93.

I agree! Although its a federal installation that requires our flex fuel vehicles to use E85. Probably drives up the price from AAFES because they know we HAVE to use it in our government vehicles.
