How shit is E70? now that we have had some time.

[niterydr]

Thanks for the good answer man! Very interesting on the amount of timing pull....how much boost was this on?

Nothing crazy, mid 20's.

Well, it more like going under the knife for winter.

JDM rear bumper, clutch, and o2 housing are a few of the things that are going to be tackled.

Sunday night sounds good, I'll give you a call.

Whoah! That does sound like a whole winter's worth of projects :P

Sounds dandy, just give me a jingle!

I have been getting 73% from Kwik Trip that is pretty decent. I'm still running the tune I made 380whp on E78 with. There is a some knock occasionally gunning it at low rpm that I need to get rid of, think I just need to lower my boost spike a little.

Holiday however is selling some really shitty 68-69% stuff that knocks like crazy, I was lowering the boost to 25psi and pulling 4-5* of timing and still knocking. I quit trying to tune for it when I found Kwik Trip still had good stuff.

I dont get why some of the winter blend stuff is so crappy? It should still have a high latent heat for good knock quench. I'm running such a tiny volume of ally in my car and I can still run plenty of timing and 26 psi of boost with no knock. Is it just mixed with 80 octane gas or what?

[merkzu]

I think the Kwik Trip stuff must be mixed with higher octane gas than what Holiday has. I dont think the difference in just the ethanol % can explain it, since I can pretty much run my 78% tune on the Kwik Trip 73% stuff.

Kwik Trip sells E85 instead of premium on all their pumps, and Holiday has a single separate pump for E85. Wonder if Holiday is buying pre-mixed stuff and Kwik Trip mixes it at the pump when you buy it? I dunno but it is definitely a lot different.

Did you notice any smell difference? The E85 I have gotten from Holiday always had a corn smell, while the E85 I got from Bobby and Steve has a much different and bad smell. I ran the Bobby & Steves, if I was going to be racing, because the car felt good on it.

[turbotalon1g]

i usually get mine from the local holiday.

[TalonFiero]

I have been buying all of my e85 at Holiday.

[merkzu]

Do you have a tactrix cable Jim? Log that Holiday stuff and then try Kwik Trip. Where's Bobby & Steve's?

I'll have to check out the smells and see if they are any different
