I've been contemplating the power output that a 93oct tune + WMI would make, and if it's comparable to the power output of an E30 tune with Stock turbo?

My tuner of choice would be Stratified. They dyno'd their ST around 292whp on E30. I dyno'd mine at 299whp 378lbft. Stage 3 + E30 tune running a 2.25" cutout. I also ran a 13.7 @ 103 in the 1/4 on the F1 tires in Joliet, IL in mid 80* weather

My Question, would a 93 octane tune + WMI net the same power levels or around 292whp? I would also probably have to spend $200+ in a custom tune in order to take full effect of the WMI setup.

I love the power gains of E85, but such a pain to mix at two different gas stations, or go to two different pumps at one gas station once or twice a week.

I'm currently running the latest COBB 93 Stage 3 tune for the winter, and damn I love the MPGs! lol But we all know we don't mod cars for MPG ;)


Thanks!

You should be able to achieve the same power on wmi as e30 on the stock turbo, you just have to figure out how much to spray to equal an e30 blend. Stratified should be able to help you figure that out.

At 500 cc my car dropped one full point (Air-Fuel Ratio) from where it was without it on E30.

If all you want is to duplicate what you get with E30, get any water injection system that fits in your budget and go.

Your tuner will have to lean it back down to where it was with E30 when activated but that's fine. Since water is cooling the inlet air much more effectively you can run more ignition timing.

You can run it everyday if you like, if you are a lead foot you will need to refill it more.

With WMI you are gaining several benefits over E30...

1. The cooling of the charge air entering the combustion chamber.
2. More controlled mixture of combustion products entering the cylinder ( vs the inconsistencies between different blends of fuels and tank fill levels)
3. If you decide to go with a larger turbo, the WMI will net you a larger overhead on your Injector Duty Cycle without having to go with other aux fueling, depending on your power level of course.
