I currently run water/meth and I love it, however if e85 was available in Canada I wouldn't hesitate a second to switch. If you have it available take advantage of it!

water meth or E85

What are you guys doing about your fuel level sensors? Just guestimating?

Perfect Example!

Today I was playing with my boostbox trying to get it dialed in, car wasnt running right, something was up.

I ran my tank nearly empty playing with settings and had an air bubble in the line from the truck to the engine, huge pain in the ass to remove.

Wish I had E85

I ran e85 on my evo and it made a lot more power over running water/meth. Ill be tuning my srt on e85 as soon as it warms up. Reccomend it hands down.

One last thing, if e85 is roughly 105 octance and pure meth is 110 or so, couldnt you inject meth and get an octane rating above the est 105? You should be able to depending on nozzle size and flow...

Dangerous yes, but also i think possible

water meth or E85

^ wrong octane buddy.


E85 is roughly 96 Oct. meth 117.

Next with e85 u can run all the timing U need and can cross over mbt and be losing power by the time u knock.

You think 100% of the fuel in your chamber is burned on every compression stroke? Even with pump fuel (all fueling) there is ample fuel in the chamber that cools and wets piston tops

E85 cools plenty as it burns (I'll say it again). And having run both (I'll say it again) in the real world I can tell you the water does nothing for performance (tried it on the dyno)

go ahead...change yours too now; again

I just went to a salvage yard and nabbed 3 units from 3 00-04 neons i found. They should last awhile for sure. They were only $12 each, too. One is from a Chinese replacement canister one of them had. I'm curious how it holds up.

E85, being mostly Ethanol, has a much lower in chamber combustion temperature then that of gasoline. Simply put, it burns cooler.

E85 has a lower octane rating than methanol yes, but seriously, have you ever heard of someone complaining about knock with e85. It CAN happen, but legit knock with E85(a good batch) occurs far beyond what you could have even achieved with Water/Methanol injection to begin with.

More then a few people have backed this up with Dynosheet's and track run's.
