guys running water/meth
Where are you tapping it in?I thought about the rubber boots that come from the s/c to the top intake manifolds but thats positive boost and Im afraid the boost will leak out.
can we spray water/meth through the superchager like right before the tb?

Yes supposedly you can spray through the SC, this is not what I did. If you spray past the IAT sensor the computer will not realize the reduction in Air temp and will not make timing corrections. My placement is just across from the map post IC. Yes this means pulling the SC but if you’re considering Water meth this should not be too big of a concern.

i have a split fogger system running a smaller fogger into the SC and the larger fogger where sneakyneon said (in front of the temp sensor after the blower). i may change this in the future and o with dual foggers post-SC pre-sensor

i have been chatting with sneakneon for a while now since i really want to do this mod on my car. I have been researching water/meth kits and have come to the conclusion that Devil's Own make a kit at a reasonable price, their tech and customer service people are top notch they know their stuff. I have decided to purchase a stage one kit which consists of a Hobbs pressure switch that triggers the spray at a set psi. I plan to set it at 7-8psi. the reason I choose a stage 1 rather than a stage 2 with a progressive controller is that at 7-8 psi the charge air is hot enough so it can benefit for maximum spray. i don’t plan to trigger the system at 3-4psi so the progressive controller is not needed for me.
Hopefully with this setup my IATS will be low enough at WOT so no timing is being pulled. Maybe a custom tune with some additional timing will be beneficial

I might go with a snow performance stage 1,its about 300 bucks.I will spray it right at the tb and see how that works.
I really wanted it to go threw the s/c because the thing gets so hot and it might pull more heat out.The only thing is I might need alot more meth/water if I spray it there.
I can consistantly pick up 2mph at the drags from just icing the s/c for 20 min before a run

where can I pick this up?Im about to order lol
edit-stupid question but can we get under ambient with or close to it?I know a few that run 100% meth and not sure if there doing that for octane boost or just for temps

get the D10 nozzle for post blower and a smaller one for pre blower. the stage one comes with 2 nozzles of your choice. call them up it is easier to order that way. make sure you tell them to throw in a fluid level sensor and LED waring light for low fliud, they include it at no charge

i am sure when the weather is a bit cooler this setup will run close to ambient at WOT. 50/50 mix is good enough straight meth can be very dangerous in case of a leak in the engine bay

Be careful when tuning for meth. The modern kits have lots of failsafes but if for some reason your car stops pumping the meth and you are still running the agressive timing map you can have major problems.
Meth is awesome! All these IAT problems are fixed with meth. You just have to keep refilling it lol

Cooling is the e55s biggest problem,I just logged mine and never went over 104 with 77 ambient temps...stock pulley tho,my 168 is lost in the mail so not on yet

that is why the timing is not going to be too agressive so if in case something goes wrongs the engine timing is still in the upper threshold of the safe zone and can still run safely without meth.
i will probably have one file with very agressive timing that i may just sue for 1/4 mile passes not for daily driving

so is everyone using the the windshield washer tank or a rear mount tank?
upside of windshield washer tank: has a low fuild check in place, less tubing to run
down side of windshield tank: have to clean it throughly, mounting pump in hot engine bay
upside of rear tank: pump can me mounted in the trunk, maybe just looks cool in the trunk
downside of rear tank: have to run all the tubing and wiring to the trunk and back.

BlownV8 thanks for your input, before making the decision on meth kit i logged my car which i daily drive for week. my communte to work is about 1.5 miles. During the week my car never sees boost, lol i know i have a very conservative drving style. hopefully i wont have to refill the tank that often.

You want to inject after the supercharger. If you inject before, the mix will become hot with the intake charge and will not really have much of an effect.
It will help your IAT's and will keep the power going for longer before the engine becomes heat soaked. The meth/water mix is awesome for controlling the heat but is really not the best solution. It is the cheapest solution in the short-term but is a pain in the long run.
I ran a meth/water from the windshield washer tank. It is easy to do with most kits. The bad thing is that the washer tank does not seem large enough and I was always refilling but if it is used at the track it will last a long time. Just driving it around and using it all the time will get you a couple of days before it needs refilling. Some aggressive drivers would be refilling daily.
A methanol injection kit is just a band-aid for a poorly designed intercooler system. In my opinion, given it is a daily driver, you are better off investing in an upgraded intercooler system with a larger heat exchanger and trunk mounted tank that can be iced down for drag racing. With the ice, you can get the IAT's below ambient and you will have some real power gains.

For you guys that already have it, is 50/50 really necessary? I know people who use washer fluid and have great results. Obviously not as good as 50/50, but it's cheap and very easy to come by.

Not too familiar with the E55s (i'm a CLS55 guy but figured the setup was the same). Is there no liquid/air heat exchanger on the E55?
CLS guys have added ones in series or upgraded the size of the stock one, but maybe there's more room up front on the CLS?
I like doing the occasional road-racing track with my pig for ****s and giggles, but the last time out was painful since the SC kept overheating and shutting off. I haven't done the pump replacement yet, but thought that I might do a bigger cooling system upgrade while I was at it and the water injection seemed like a possible option if the upgrade won't work how i want...

Would the upgraded cooling system keep the SC 'on' during road-course racing? I know you do drag where i can see why you could still benefit from water/meth, I'm curious if that would be necessary for other racing types.
