i see forced induction setups more on this site than any other, why does nobody use e85 on here. i know it takes more volume "20-25%" if i rem right (more fuel mods) and little worse gas mileage (if your goin FI in the first place you shouldnt be worried about MPG's) but i find the benefits to out weigh spraying meth and using another pump. im planning on switchin over in something else i go fast in, just thought id ask why ive never seen any mention of it on here..

oh i also know some places still dont have e85 pumps readily available, but as long as you dont live in the sticks i dont think it would be too hard to find..

 

I agree. I was just looking into it. Don't know what it is going to take to switch everything over. I thought with the 105 octane that would help with timing and cooling. Anybody ever run this on a FI set up??

 

I'm running it Zero knock with 19lbs of boost and 20 degrees of timing. It pulls pretty hard with the extra timing E85 allows. On 92 octane I'd probably be capped at 10 degrees of timing at this boost level. The cost savings along with the increased need for fuel (about 20%) make it a wash cost wise with premium fuel. Not bad for 105 octane at a couple bucks a gallon.

 

i live in mississippi and have not seen one sinlge e85 pump here yet..... i wish they would hurry up

 

I was considering it until I read that the inconsistent nature of the fuel affects your tuning. I guess it doesn't much matter to a car that is designed to automatically adjust for the percentage of gasoline to alcohol, but in a vehicle with a fixed tune, it might be disastrous to your engine if the guy mixing the E"85" at the plant isn't paying close attention. I understand that the ratio changes a lot, to compensate for winter/summer, or even other reasons.

 

yes there are 3 different blends if i rem right, depending on your location in the country and seasons factors into what mix you get, living in somwhere cold you might only have the strongest blend 2mths out of the yr. where as southern people would likely have the strongest blend all yr long. the stronger the % of ethenol the harder it is to start in colder climates.

and yes people say some mixes vary, but arent you depending on a steady current mix% now at the pump on your fixed tune.. either way i was on id be monitoring it if taking it to the edge on FI.. just my thoughts on it

 

This isn't my 1st E85 vehicle running w/o factory E85 programing. The winter blend around here dips closer to a E70. Unless you are careless with the amount of timing your running saying it might be disastrous is a bit of a stretch IMHO. Comments like yours usually come from someone who doesn't have any experience running it.

 

e85 is 105 octane right. so e70 from ive looked up is 98-99 octane?? and thats the winter blend. so id assume 98octane is still better than 93+meth octane wise right..?

 

what does it require to run the e-85?

 

No E85 fuel available in this state. Too bad. It seems like the E85 concept never really took off like expected.
