I had been getting a little KR on 93 gas at 16 psi so I have been running a 50/50 mix of 93 and e85. KR is 0, and now I'm at 17psi still no KR. I've been thinking about getting an e85 chip and 60lb injectors to run 100%.

C16 or E85 when it comes to making the most power?

I read more impressive spreads before, but I can not locate them now. What I read before showed more like a 100 HP gap between the two at around the 600 HP range.Thats a Mustang site...we all know how the Ford guys love to lie

Basically E85 adds the low end torque benefits that methanol/ethanol have-with their slow burn rates and higher timing required, and the benefits at the upper RPM range with the gasoline mixture allowing a quicker burn than either pure meth/eth.
If you had just meth/eth you have one temperature that the fuel will burn best at, with E85 since it is a mixture of two fuels, you get two temps that the fuel burns best at, so you get the best of both worlds essentially.
Here's my input, I wouldnt mess with mixtures unless you know your tune and can follow it in the car. I ran 50/50 in my converted 84 GN with 38# injectors on a gas TT chip the entire time I owned the car. It does work and helps spool up and knock tremendously but you really need to pay attention to your car and your tune. Mixtures can be off after you fill up multiple different times so setting your boost based on your mixture is a risk. If you want to run E85 and have over 50# injectors already, just buy a 100% E85 chip. Keep in mind, 50's are the minimum so if you have a big dog set up, spend the money on larger injectors. We mostly use Trick Flow 120's or 80's in every set up we do. It's much smarter to spend a little money to do it the right way instead of risking a motor.
E85, in my opinion was made for our cars. Everyone that I have done conversion for have been jaw dropped at the difference in their cars.

At the time I purchased the 60's, they were the biggest for unmodified ecm. I will be doing 120's, and a double pumper. I have a bigger turbo and know that I could be limited with boost. I can run 18psi on 93 oct. so far. I thought I could put in about 5-7 gallons E85 for fun.

How much HP can 96lb injectors support running E85?
If you know what the total capacity of the tank is multiply it by .28 to be sure of going light on the mixture and the end number is how much E-85 you can use if you fill it to the top.
14 X .28 = 3.92 This is an example so you get an idea.

I believe it's an 18 gallon tank. I just filled up with 93 octane. I will do some testing/tuning tomorrow to use up some gas.

I have to preface this by saying that saturday night i finally got my car back together and running right after valve springs, a power plate, and AFPR. After adding the plate, i tried an extra turn on the boost controller. The SM said "fugeddaboudit" with a kr reading of 4.2. Oh well. Fast forward to tonight:
I was just below 1/4 tank by the time i got to the station. By my calcs i figured 4 gal of E85 and 10 gal of 93 would top it off. The sticker on the pump read "Minimum 70% ethanol". Fuzzy arithmetic later, i decided i'd get 4.5 of E85 and "the rest" 93. It ended with me cramming 10 gal of 93 on top of the 85. I did a few figure 8's in the parking lot of a nearby grocery store to mix it up. Drove around varying speeds for about 15 min (maybe naively thinking the ECM needed to re-learn, and also to get the true mix into the lines). After that, i put the pedal down. Aahh, nothing special...not too impressed. Since i got no kr, i pulled over and put a turn on the rjc bc. Ran it and no kr!!! Starting to feel better!!!!
Put another turn on the rjc bc......no kr!!! Feeling much hotter now!!! I'm also getting a little more nervous. Anyway, put another 1/2 turn on the bc.....no kr!!!!! By yhis time, the stock boost gauge is fully lit up and brighter than i've ever seen it, even with the old pitbull chip. I stopped there for now since it is pretty late.
Anyway, the butt dyno definitely approves!!! I figure i'm running 2.5 psi or so more than i was before with no kr. It is definitely faster. Faster than my last track outing for sure, and this was just on the street. I'm sure the new springs helped with pulling in the top end though.
To E85 i can say... I'll be back. Those hemi's better watch out!! I can already take the 5.7's. Now i wanna run an SRT8 and see what happens!!!

Not sure of total boost - I don't have the Autometer boost gauge hooked up yet. My O2's ran about the same as with gasoline - 775-ish at the top of 3rd. I know the stock boost gauge is not reliable. I did NOT adjust FP either up or down. However, I set my FP to 43 line-off on Saturday. Without alky injection, Boost is just a number; you're only able to run whatever boost the motor will let you without knocking. If that means 14PSI, so be it. I tune for Zero knock and the only knock control I have is to add more fuel via the chip, or to adjust timing via the chip. Before E85, I had my car set up where it likes to be set up which is:
FP 43PSI line off
Timing at 20/18 as received from TurboTweak
Fueling increased to get 02's in line.
Zero knock once the O2's lined up.
My experience with the 4.5 gal E85 to 10 gal 93 mix is that when I change NOTHING ELSE (FP, timing, chip fueling, etc), I am able to run 2.5 turns MORE on the RJC boost controller than with 93 pump gas. As a rule of thumb, one turn on the BC = 1PSI. So I'm therefore ball-parking (yes, guessing) that I am running at least 2.5 PSI higher with E85 mix. If you'd like I can do a temp mount of the boost gauge so that I'll be able to tell you I went from 13 to 15.5, or 14 to 16.5 or whatever. But just because MY numbers do that, it doesn't necessarily mean that anyone else will be able to do those particular numbers.
I think what you WOULD be able to generalize is that - you can run MORE boost with a mix of E85 and 93 than just plain ol' 93. I may be proving a point that's already proven, but it's still fun to do it. And if a dummy like me can do this to increase performance, any of us should be able to do the same!!!
Try it - you'll like it. My plan is to get new injectors, an E85 chip, a big ol' fuel pump, and a few tanks of straight E85 and have myself a good ol' time maxing out the stock turbo!!!!!

I just wonder if, a few years down the road, the short-term gains people are posting would be worth any potential damage / early parts failure caused by using E85. I would love to see what sort of difference it could make in my driver, but I'm just not sold on the idea enough to pump a couple gallons into my car "just for fun."
For the record, I already have a new Walbro pump, hotwire kit, AFPR, 60# injectors, and a 93 octane TT chip.
