Default Meth & Flex Fuel and Supercharged

Anyone out there running the flex fuel system, meth, and boosted? Just curious if anyone could share their setup and performance. Thinking about adding flex fuel to my setup to see the benefits of E85 and like the idea of flexibility to run 93 when needed as well.

Any tuning issues when the computer switches back and forth?

Thanks,

TA

I've been running meth a long time on Turbo Buicks, I'd say keep it simple. Run one or the other and tune for that. It appears you already run meth, so I'd assume you run increased boost with a boost controller of some sort. To run just E85, perhaps, depending on your setup, just turn your progressive alky controller off and lower the boost a bit and see what happens, then start messing with one thing or another to get more out of E85, timing, boost, fueling...

We have done quite a few C7's that are boosted, flex fuel, and meth. We offer a C7 fuel system that will take you to 900 rwhp on e85 in a manual car, so a little less in an auto. I will be glad to answer your questions, give us a call during the work week 8-6 az time. We will be closed on mon though.

Thanks Joe. Appreciate the input.

I'm not looking to do full e85 I'm just very interested in being able to use it if I want with the flex fuel system. Just don't want to spent the money if it's not really worth it.

Assuming the fuel system you're referring to is for full e85 setups?

What kind of power numbers have you seen at 10psi, meth, and flex fuel?

dont waste your time if your not planning on being able to run full e85, otherwise you have to always watch your ethanol %. don't have anyone running 10psi on e, but 14 with an a6 auto, our longtubes we make, our cam, novi 1500 we are seeing 841 rwhp.

Really?? I thought that was the beauty of the flex fuel kit though. It monitors the ethanol content and notifies the computer to adjust accordingly. One day I could run E and the next 93...

Is it not that smooth? I don't want to run full E all the time because there's only limited places to buy it in Dallas,

Interesting. Running those mods with e is the car daily drive able?

Mileage is probably awful but that is not the goal of these builds

There are people doing it. Depends where you are at with your fuel system. From what I understand no tuning issues. DSX Tuning could answer that as they make the e85 kit and he tunes.

I think your misunderstanding me. You can run any variation you want in the tank, but when you tune it you need full e85 in the tank. After the tune you can run 50/50, 60/40, 30/70..etc,etc. But you need the system to be able to keep up with full e85. Otherwise if you tune it on 60% ethanol and the next time you put e85 in the tank you have to be sure you don't fill up to much e85 and go over that %.
And yes it's a super smooth transition and zero side effects other than crap gas mileage lol.

Just for reference I get 20 MPG on E85 vs 30 on 93, highway only. As advertised, 30% decrease in mileage but the E85 is 1.60 and the 93 is 2.80, which is 57% cheaper so even with the mileage decrease I am getting what is almost like race gas for less than pump gas.
