E85 is the way to go vs 100 or C16..... As far as the blend change you will see little difference between E70 and E85, this is from a year of experimentation. However you should not "skimp" on an E85 fuel system meant for an FI application, E85 and FI are a wonderful combo "if" setup correctly...

I agree. Carlos says that your stock fuel pump on a N/A E85 car is more than enough.

I just did the math and your paying nearly $5 per gallon. You could simply invest in a five gallon if torco for $150 and add as needed. You can buy a simple test kit and figure out how much octane you need. From what I have read it is only in the winter that you have to be concerned about e70.

E85 is really a nice fuel to use when you factor in it's less than half the cost of 100 octane at the pump. ($3.15 verses $7.25 at the pump)
Some benefits.....ethanol runs much cleaner to the point it leaves no carbon residue even on the tailpipes, cooler in day to day driving in as much that I saw a 5-10 degree reduction in coolant temps, and amazingly intimidating. (Oh man you're running E85....I'm not racing you)
Things to note.....yes ethanol percentages do vary by station so a hygrometer is your friend verses the unreliable test kits for sale, bump pump prime time in your tune to help with the lazy starts (not really an issue but it always bugged me), and reduced range.

as long as I order 4 at a time I pay no delivery. I run ms109 not E85 but you should try and get free freight most will throw it in. If not its at least free on the last 3 drums. Truck freight is prices by the foot and 1 drum on a pallet takes the same room as 4

Yeppers. It's in the works right now. A buddy of mine owns a gas station that has E85, 93 and a few other things. We have been trying to talk him into doing the E98 because he blends his at the pump versus already having who knows what mix shipped to him. So he will just take the blender out of one of the E85 pumps and let it be. E98 which will read 100% and we are off to the races haha. Screw that 101,104 and C16 prices crap I am out on that!

It very well may do that but then the question is "how long will it last"... Ask me how I know... Mine did not last long at all which is why I threw away the pos bap and did it right which I should of done the first time.

On E85!! I'd never try it, but as I stated it's been done.. I'm pushing the limits in a NA E85 setup.. I was going to get a RSI kit but decided to push the limits of the stock short block NA.. on my RHS based engine I'll be doing a fuel system for sure..
