Default Is it safe for a daily?

My previous owner had ran meth for years so the setup is already there. I just need a new tank and the mix. Basically, what I'm wanting to know is it safe to run a meth/water mix on a daily driven car? I do some spirited driving occasionally, and maybe even a quick pull better or there. It's not being tracked or dragged at the moment, so if that info helps. I appreciate the input in advance!

Yes, I did water/meth the worst way possible, made most mistakes that could be made, and the car kept going. Set it up, run just water if you are really worried about it, and go about your business until the tank is low. What kit is installed.

Yes water/meth injection is safe for a daily driver. I agree with shaman, if you want a good safe setup just inject distilled water. Will provide lower cylinder temps and knock protection. You just want to be careful how much you inject because you will need to be tuned for the appropriate amount. Since the mixture isn't injected until you are going WOT, there won't be any difference between meth and no meth while just driving around normally so daily driving won't be a problem.

Excellent info guys. I was assuming it would be alright, but I wanted to get the general consensus. I can't remember the kit brand/name at the moment. I'll look later. It's already installed, as I said. However, the tank was taken out and I never got it off the p/o. I'll have to order one up. Any suggestions? Can you mix and match brands?

I've talked with my tuner on the matter and he's versed in meth/water and tuning with it. So he's gonna help me get all that straight.

Does size or type of tank matter? Ive looked at both of those sites, and Im not finding much that looks like a meth/water tank lol.

Size is dictated by how much you plan on using it. You could use the 12L tank that mounts to the back of the back seats, you could pick up the sprayer tank that mounts behind the wheel well in the truck, or you can do your own thing. The material you want is HDPE. If you want to figure out what you are looking for, you can search for tanks here or iwsti. If you want to find tanks on those website, pull up devil's own or snow performance, and they compare their tanks to what you see at flambeau or us plastics.

i used to run a 1 liter tank that would last as long as a tank of gas.

Umm yea, I'm not wanting to mess with it every time I fill up. I found a 2.5 gallon tank. Might go with that one. I'll post up what I decide.

My methanol system uses the windshield washer tank in the engine bay. I mix 50/50 meth water. It's my daily driver and I bought a 5gallon jug of m1 methanol from vp racing fuels. Its less than 30 bucks and will last you many years. My system is tuned to inject once boost hits 11psi. I drove multiple long distance trips and didn't use a drop of methanol....you only use it when your really having fun.

The only unsafe part about it is that if it fails to inject or is empty then your combustion goes lean, since the fuel map assumes its getting the meth/water mixture plus the fuel being sprayed in. It's two standalone systems that don't really communicate. But say you are empty and not racing the car, then you have nothing to worry about because your fuel map isn't in the range of needing to inject the non existent water/methanol.

I hope this answered some questions and didn't confuse you. Btw I have the smc kit

That's great info man! Thanks. What kind of power gains did you see after running it? Are you on 93?

Yes I'm on 93 and the power gains aren't directly from the w/m injection. The power is from more boost. The injection makes it safer to run more boost.

W/M is a safety feature. And as I described before its safer until your fuel map sends a little less fuel anticipating the addition of the w/m volume but instead that volume is taken up my more air. Which is where problems occur because then the air fuel ratios become lean. It would be amazing if the ecu knew when the pump failed or mixture was empty and would run a different fuel map but that doesn't happen.

Hope that cleared things up. You shouldn't worry about using w/m injection. I would suggest considering using the washer fluid bin in the engine bay to minimize lag and possible leak in the hoses, which would have to run a long distance.

Gotcha. Yea I understand how and why it's safer. I've been reading up quite a bit on it. My car already has a kit setup, I'm pretty sure the tank was mounted in the trunk. However, everything is there but the tank. So I'm looking for a new tank and some mixture. If you could recommend some sites like others have, that would be great.

Sorry I don't know of any sites to get tanks. Iv had my system for a while and never needed a tank. But some members have given some suggestions and I'm sure others will too. Good luck

some systems have a failsafe between a high and a low and will cut to spring pressure i think you need the truboost for that

Actually, when it is injected is often during positive boost (iirc, starting normally at about 7 psi and going to full flow at 15psi and up), not just WOT. Unless it has been set up to only inject on WOT.

This could be a possibility for stock application. But the concept is right the system is attached to the turbo reading. It injects past a set psi reading not from the throttle position sensor. Read a few parts back to see how mine is set up

I've heard mixed reviews on the AEM one, but I've been eyeing the Stage 2 Snow Performance kit. I see the kit sells for around $450 shipped, but the tank it comes with looks pretty small.

How long does a gallon of fluid usually last?
Edit: Read the FAQ; about 2-3 gas tanks.

I use a Devils Own stage 1 system using a pressure switch in my current car and I've had no issues with it.

well the aem kit brand new runs around 380-400 without a tank.
and the failsafe brand new cost me around 280.
youd spend almost the same amount as an aquamist kit, but its all on your preference i guess.
im satisfied with my AEM kit.
although ive never used another kit before so i cant compare it.
