I thought you built your motor Keith? When you had the cam issue? or did you just fix the cams? E85 is awesome!

Beast! Sounds like a monster on that sweet E85. I also cannot wait to see the 60-130 times. Congrats Prototech & Protomotive!

Blue Max 2150cc.
I have so many logs all over my computer - I couldnt locate any files with reference to injector ms at 1.5 bar with the 2150s. I did find one at 1.4 bar though. The injector duty cycle (IDC) was ranging between 45-50% across 6000-7000 rpm.
These injectors have enough in them to easily support 1200 whp+.

Averaging 13 mpg in the city per tank combined with some periodic full throttle runs here and there. If I take it easy and just drive it works out to 15 mpg. Steady highway driving will get up even higher.
Definetely still worth it by far compared to race gas.

this is awesome. Not enough E85 out here on the east coast in my area. One thing, I think your consumption figures will slide a bit as you'll probably get considerably less MPG with E85 than the race gas, no? IE you'll use more than 87.5 gallons per month of E85. this link here shows a 26% reduction in MPG. Still worth it though, IMO.

Already took care of that.
Right after I switched over from 93 octane to E85, I ran the stock fuel filter at first using the factory fuel pumps and 80 lb injectors.
It wasnt until a month later that Prototech pulled that filter out and replaced it with a brand new large fuel filter that was a better fit with the larger fuel lines.
Heres a pic of the filter:

With no changes in performance mods, has anyone out there compared their 60-130s in summer temperatures and in winter temperatures to see the difference?
For those of you that have, what were the temperatures (that you recall) and what were the time differences?

Our set up is utilizing E85, Aqua Mist (water/meth) and dual injectors accounting for a total of 2650 cc's. Due to the elimination of the vario cam we phased in the second injector (on each cylinder) so as to obtain a smooth idle and low end.

On winter 20 degrees Celsius i did 100-200km/h 5,6sec best.
Now the weather is like 34 degrees Celsius, humidity is 90% i do 100-200km/h 6,5sec best.
Those runs were performed at night. I believe that if i try my car now at day dim were the temp is around 43 degrees Celsius it would be another 0.5 sec slower
.I hope this helps

Awesome info!
After running E85 in my last 2 cars I love it vs. race or pump
The problem with running e85 here in Michigan is that it is only E85 during 1 month of the year (July). In the winter it is E70 & changes in spring to 75,80,85 then back again in the fall.
Here is a chart for all of the states: http://www.e85mustangs.com/regions123.html
So 2 options?:
1. Tune with e70 & run it that way all of the time so tune has a built in "safe" level (only problem is your leaving extra power on the table when it switches to anything above e70)
2. Have an ethanol content sensor wired into a standalone ECU that switches maps based on ethanol content (anybody dealt with this or something similar? ideas?)
Thanks!

Yes

This would be another way to compensate for varying ethanol ratings.
