I have a Sun ignition box that is good for 30+psi on E85 stock gapped stock plugs with zero misfires ever.

It's not a matter of not enough spark. The problem is that the EtOH does not atomize below a certain temp. It just doesn't go "bang". If we are still going to run 85% in cold temps, we need to get some heat into the head, intake mani, fuel rail, or fuel itself.

That, or go down in EtOH % to get it to atomize at a colder temp . . .

Stock IX with just a Megan TBE (Invidia O2, TP), ETS Intake, ETS IC Kit, 255 FP and 1000cc. Put down 380awhp/364awtq at Reese Tuning last week. Stock Cams, stock turbo, stock ECU, no porting. Corn Guzzler!

That dyno reads high and this dyno reads low. Or maybe Scot likes to lean his tunes, which was the case last time he tuned mine, using no WB at WOT with almost 12.5, and knocking like crazy.
The point is, I went from 328/326 to 380/364 on the same dyno. That's a 52awhp/38awtq gain with just injectors and a E85 tune. I have dyno charts to back it up.
What was your number before? And do you have dyno charts for just the E85 switch? Meaning what's necessary ONLY for the switch, not what other parts you put on at the same time.

Another downside is too much torque stock clutch needs to be replaced!

On an uncorrected DynoDynamics I put down 356hp/371tq at 28psi, stock I was around 220hp/240tq.

here you go car was breaking 400wtq on its way up to peak tq but clutch had had enough. No parts added just e85 baseline for 91 was same day 20 min earlier. 28psi

332awhp on a stock VIII with just intake and exhaust? I knew that dyno read high, but not that high. Wow! The Dynojet I'm tuned on, with a VIII with those mods typically put down 292awhp, just as a reference.
I'm at 26psi not 28psi. Will have dyno charts up tomorrow.

I have a IX with o2 housing 2.75dp test pipe greddy ti ets fmic and arc box. My car is stronger than most IX im putting down higher numbers then most do with cams. To answer your question about the dyno reading really high I put down 317 on gsts mustang dyno with those same mods so the difference is only 6.9% do you know what stock IX's put down on reeses dyno?

You need to change your "Drives:" part Brian.

Here in Brazil we have ethanol for more than 20 years on pump. We have flex fuel cars for almost 5 years too, and flex and ethanol cars, have a cold start sensor, that under a given temp this sensor will inject gas for cold start.
It's pretty easy to do a system like this. You don't need the sensor, you can do it with a button on the dash a reservoir and a washer pump. If you guys need a picture, just let me know.
I also recommends that if you do not drive your car at a daily basis, you should have your injector cleaned more often. At least we do it as we have pure pure ethanol on pumps.

The corrosion issue, is not a problem anymore and if you have a stainless steal exhaust you will be fine for several years.

On Reese Dynojet, my IX with Megan DP TP CB, ETS Intake, ETS IC w/LICP and UICP put down 328/326. This is in line with most IX's on stock Cams and stock Turbo on 91oct. We only added 3psi w/1000cc and E85, with a gain of 52/38.
