Also, where do list people install the tank? Trunk?

Most installs I have seen mount the tank in the trunk on the side wall. Pump is mounted below the tank under the trunk liner.

Is it challenging to run the lines from the tank all the way to the engine area?

Not at all, it's actually pretty simple. It slips behind the trim that runs along the floor board/drivers door(s) area.

And the tank holds a water/methanol mixture, correct? 50/50?

I might have found someone to install it but won’t know for sure until Monday. If all fails, I’ll have to install it myself although it looks pretty scary.

I literally fixed that within 5 seconds of first posting it. You must have beat me to it within that time. That’s iPhone spellcheck for you...

Hahaha. Damn iPhones.

But yeah. That tank holds the water/methanol or any alcohol mixture for that matter. I use Ethanol instead of methanol.

It's really not that bad of an install. Just gotta read the install manual step by step.

Hi guys,
So i just got back to modding my car after spending weeks fixing the boost leak ( bad gaskets), now i'm getting a W/M kit really soon. I just have 1 question: I've read on the forum that people are using the kit for varied purposes, some using it for additional fuel, some using it for cooling. Is there any difference for the setup or just depending on the fluid that you put in the tank?
Thank you!

Only the fluid changes the purpose really. Higher percentage of methanol aids in fueling, higher water percentage aids in cooling/lowering IAT's.

Charge pipe injected kits tend to be used for more of a cooling and fueling combo. Port injected methanol kits are used mainly to add fuel/meth, not so much for cooling. Port injection also ensures the meth is getting evenly distributed.

How’s your custom tune going?

I found shop that will install any meth kit I bring them and now I’m deciding between the BMS kit and AEM. Might have to call both vendors because I have so many questions. The BMS kit is better I think with JB4 because that’s the controller, but I don’t want to spend money on JB4. AEM already has the nice controller. Might end up getting the AEM kit + BMS stealth tank.

The custom tune got cancelled as I wasn't happy with the way the tuner was making adjustments. He honestly didn't know what the hell he was doing in my opinion, basically just threw boost at the tune and that was it, I'm surprised he's even in business. They guy offered me a full refund as long as I wouldn't bash his name, so there for, I can't say who my tuner was.

Anywho, I ran the time at the track (11.87@116) I was looking for with the 2H E30 OTS Map. Cooler ambient temps and the meth kit shaved off over 4/10's of a second which is pretty huge in my opinion.

I have experience with BMS, AEM, and Snow Performance kits. I tried the JB4 stack and wouldn't put a JB4 on my car again if you paid me so the BMS Kit would be strong no for me.

The AEM kit is easy to install and wire. My opinion is this. Install an AEM kit without the kit figured into a custom tune. Use no more than a 50/50 mixture and you'll have a nice octane bump for the shit fuel on the west cost as well as cool intake temps. It's a win win for you guys.

Yeah, I’m strongly leaning towards the AEM kit with the 3 gallon BMS stealth tank.

So you’re saying no custom tune?

As long as the meth kit would allow me to run the Stage 2H map well, I’d be very happy. I think the car ran “reasonably” well with it as it is, but the added cooling and octane from the meth kit should hopefully smith out the ignition timings and eliminate knocking.

Correct. I wouldn't get a custom tune for a meth kit unless you're going to spray meth/alcohol percentages above 50%

Does the AEM controller allow you to chose how much meth you’re spraying and is it throttle and boost dependent?

The AEM kit is activated by boost pressure. So you set it to start at a desired boost pressure. I had mine set to start spraying at 5psi and then ramp up to 100% pwm at 20psi.

The kit itself won't adjust the water/meth mixture percentage. That is only controlled by the end user in the tank.

What I meant was, for example, how much does it spray at 5psi compared to 20 psi? Can you adjust how much liquid comes out of the nozzle when it sprays?

Oh, sorry lol. Yes, the starting point equals 25% pwm and then it progressively goes up until you reach your desired full psi.

So a 5psi starting point would equal 25% spray pressure from the system and ramp up from there.

So if you’re spraying 100% at 20psi...is your turbo really hitting 20psi? Is that because you’re running E30? Isn’t that a lot of boost for this turbo? With the Stage 2 91 oct map I’m hitting around 15 psi max ( it was 16.3 max with the Stage 2H map)

My turbo was hitting and holding 21psi with the custom tune I was running. Timing was just lower than normal. Timing wasn't horrible, just wasn't as high as the less aggressive OTS maps.

I believe these stock EWG turbos are stronger than most people know. I mean, most Pure stage 2 people are running mid to low 11's. To run an 11.8 with the stock turbo shows it's pretty strong in my opinion.

That's the reason I chose to jump to an F80. I can't justify dropping 3-4K for an upgraded N55 turbo for 0.6-0.8 second faster 1/4 mile times.

Tuners are also losing sight of the N55 with the B58 really starting to shine in the tuning development. Just my opinion though.

Wait...your jumping to an F80?

Yeah, I can’t justify getting upgraded turbos myself. The meth kit will be the last power upgrade I make. I may not break into the 11s like you because I won’t be running E30 but it should still be pretty beast. I’m already pretty happy, let alone with the meth and hopefully running that nice Stage 2H map that I’ve been obsessed with ever since I’ve tried it.

Also, i plan on keeping the car another 3-4 years or so and don’t want to invest thousands upon thousands of $$$, and then hopefully move on either to a C8 or if my career change takes effect...to my dream car (that’s “somewhat” in the realm of “affordability”)...a McLaren 570s.
