I was wondering what people's thoughts of running a water-methanol system on a turbo slingshot? I have ran them on diesel applications and was impressed. I am local to Snow performance here in Colorado, so I think I might give it a try on the Sling.
Water-Methanol System

Sine you evidently already are running a turbo, I'd email Bob from MEFIburn and ask what he thinks. I'd be concerned about unexpected influences on the ECU's feeding of the fuel system. Better safe, than sorry.
-
MY understanding of the mixture could be wrong, but I believe the water functions to delay the combustion process, yet the methanol is designed to produce additional energy. My main concern about using such a mixture would primarily be focused on the additional energy introduced into the combustion process by the methanol, since the ECU has no programming to allow for it. Might be a non-issue, but I'd want additional info before proceeding.

Would gain you a few extra HP on a turbo setup. It would definitely keep the tops of the pistons clean
...You would have to run an ECU that knew you were adding it into the mix. Not sure if the stock ECU can keep up with an additional component adding in the mix. It may. But I'm not sure it would be worth the effort in our situation. Maybe
....If one of y'all does it let me know how it works for ya..

well just picked up snow performances stage 2 water-meth kit. Guess I'm going to be the first sling with this system. Will let you know how it works.
Just noticed your post. Keep us in the loop on how this works for you. I am curious. -
I did Meth, my teeth came out.

rabtech I am running a Hahn at 9 p.s.I right now. I am mainly looking at the benefit of not going lean as boost is added more t h an anything. I am sure I will gain some power with it. Should have it installed this weekend.

We have installed a lot of water/meth setups on the Solstice setups and definitely prefer water/meth over running E85 for extra power. The water/meth setup does some really nice things, it keeps your intake valves and pistons really nice and clean from carbon buildup, it effectively raises your octane and allows you to run more timing advance. Typically we see around a 10% gain in power when running water/meth when tuned for it. That being said, if you do not tune for the water/meth, you typically will actually lose some power since the octane is higher and the slower burning charge will not be taken full advantage of. Without tuning, the water/meth setup will help prevent detonation though, but a tune is highly suggested to take full advantage of the setup. If you have any questions while installing it, feel free to ask we have installed the snow and AEM systems quite a bit in the past.
Have fun with it!

Although I'd still like to see a comment on using a water/methanol injector, from Bob at MEFIburn, This is beginning to sound like it might have potential to avoid one of the biggest problems facing turbo users, so I'll be following this thread to see what happens.
-
But wouldn't you always need to be running the methanol if it was tuned for it?
-
Yes, If you are tuned for it, you would always have to have it spraying. The controllers though are setup to typically start coming on at a certain boost setting and do not spray all of the time. We usually set them up to start spraying at around 6 psi and then the controller ramps up to the max boost psi. With the Solstice/Sky we typically tie the water/meth controller into the boost control solenoid, so when the water/meth tank is empty, or if the system encounters any other issues, it will limit the boost to a lower level that is safe without the water/meth. Then once the system is filled back up or the problem is corrected, the system goes back to full boost.

I think I likey!
-
Sounds interesting. How large a reservoir do you use and how many miles between filling the methanol/water reservoir?
I hadn't realized that setup had its own controller and ASSumed it was like older injection systems. My Bad! -

I got my Hahn turbo kit back in November 2016 and then learned of the swing-arm recall. I plan on installing the turbo once the current recalls are done. Thanks for posting this and bringing it to my attention.

Well the Snow kit is installed and I think my motor likes it, seems smother on the top end and don't have to wrory about detination as i build the boost. I have the stage 2 with vc-50 digital control. I have it start spraying at 3 p.s.I all the way to 8 p.s.i. I will have to find a dyno in my area to see if there are any true power gains, but as of now it is a great kit. I placed the motor and resovior in the passenger box. I couldn't find any spot under the hood that It would all mount.
I know a shop in the area that can dyno it. I have been waiting till everything is installed before I go and have them dyno mine.
