hmm, I like this idea, It wouldnt take much e85 to help out quite a bit on pump gas, Ill be doing this in the winter time.

 

Yeah, if its available to you guys, I would be all over it, the benefits are awesome for anything boosted or over 11:1 compression. I am fortunate to never be more than 5 miles from an e85 pump here in MN, its everywhere. It literally is $2.69/gallon race fuel.

 

Just curious, did the mileage drop much when you switched? I have an e85 gas station about 5 blocks from my house.

 

I have ran a 25~50% E85 mix and it worked out really well you just have to add to your PE multiplier to keep AFR in check. If you have a rich 10.5:1 tune it will be about 11.8~12:1 with a 30% mix. Don't do try the mix unless you have a AFR gauge! Once you get past a 30% mix you will prob have to start messing with your VE table to keep it crisp.

 

What afr do you shoot for with 30% e-85? with 100% e-85?

 

hmmm i think im gonna try this! i think my dual 255's and 80lbers will be enough to support 25-30% e85

 

Mid 11's on the wide band calibrated for gas. I run 68lb injectors with 62psi fuel pressure, and 2 meth jets. Without the meth it starts to run out of fuel around 12-13 psi.

 

yal havent heard about winter blend and summer blend...??? they say that in the winter blend its e70 not e85 and on the summer blend its e85, not sure if its true but that is what i heard, can anyone answer this..?? btw is e98 any good..??

 

winter blend e85 IS true. Cold starts are a big issue fot e85 cars in cold weather. they drop it to approx e70 which changes the tune as well...

 

Yeah my stock 02 tahoe will not start when its under 20 degrees, it take 5 or 6 trys then I have to keep at 2500 rpm for a while. Thats why I think this mix idea will work good in the winter.
