400+ WHP E92 M3 on Ethanol [Flex Fuel]

Nice, that makes more sense. That is appropriate cost of well designed exhaust system cat back or in this case a full system. I feel like the e85 fuel system at 1200 is high too. Not sure if anyone has reached out to BMS, and I know this wouldn't work on NA, but the JB4 with fuel flex wires can be had for a little over 600. I wonder if BMS would be interested in designing something for this platform and enable flex fuel wiring?

Vishnu made a few piggyback for the E9xM3. Not flex fuel but multi tune capable -- pump gas, meth, or you could program your own. Unfortunately, NLA.

U mean for the 335 lol

[pbonsalb]

No, I mean for the E9xM3 -- I have had one on my 08M3 for 4 years. I run 70/30 meth/water plus 93 with higher timing targets, about the same as you could run with 100 octane. Many of these cars underperform in hot weather, but not with meth. E85 would be even better.

They made an E9x M3 piggyback too. All it did was meth integration and code clearing

I just ordered my flex fuel Kit From BPM, my car is supercharged ESS VT2 650 kit and makes 505 WHP on a SAE corrected hart breaker Dyno. Yea yea some of you my find this numbers low but remember a Dyno is just a tool, base line before and after= gains or loss.

All I know I pull pretty hard on JB4 and Turbo back M4's and other 625 kits.

Time for some korn power and BPM Magic!

Lmk how it works out for you. Pretty sure the fuel pump and injectors can't handle a full tank. Was told 50% mix works though.

I think at most 40%

Looking into it for the cooling issues alone that I get here in vegas.

We've been selling the AFD Flex Fuel Kit and we think it's an excellent built kit with great support from the guys at AFD. We're authorized dealers and have them in stock!

Love seeing results like this!

Would highly appreciate where to source bigger fuel Pump and more injectors for my ESS SC I have Bosh baby blue injectors.

Thanks in advanced.

Mike from BPM will take charge of this upgrade but any advice on a well taken.

Best thing to do is measure injector duty cycle. The blue 650 kit injectors will run out of room before the Green 42# Bosch injectors will. With more than 50% E85, I suspect that these will run out as well or will be near the fuel pump capacity. Only way to tell is to measure twice and cut once

Mike Benvo did you get my pm?

I haven't checked.

I will by Monday. Sometimes I'm on the forum for pleasure instead of work

Thanks for sharing your experience, may follow your lead at some point. Need to see if there is E85 near COTA.

Finding Ethanol is really the hardest part, we don't get pump ethanol here so we buy 5 gallon barrels and just fill up all day long lol. For the power gains, nothing beats it on a naturally aspirated car.

What injectors and fuel pump would allow a 620 kit to run 100% e85?

Yup, supercharger won't work in this heat, unless I set up the car with cooling mods and do like 1 or 2 hot laps then cool down (something I do not prefer doing).

Mit_Boost Bmw doubles definitely agree that the SC is the way to go for HP/$, but for a track car I really think E85 is the most reliable way of getting decent power out of the engine. I would skip headers if I am on a budget.

Wise words Mike.

I just buy a 55 Gls E85 Drum from Sunoco Race fuels.

Is that estimated crank HP, or actual wheel HP?

I don't like Dynodynamic dynos for that particular reason - they have a shootout mode that basically inflates the numbers to be like a dynojet (which is the standard) or calculate crank HP.

HP at the wheels. To me, the difference between the previous tune and the current one and the gain after adding ethanol is what I am after. My car might put more or less on another dyno, but I am certain I am now making extra power using ethanol (estimated to be 30 WHP based on the dyon runs).

Have never on any car seen that much gain on motor with e85. Boost yes and spray yes but 30 wheel from maxed out pump gas tune to maxed out e85 tune. I don't see it at all.
