Be careful with that high of a meth concentration in you windshield washer tank. I ran 70/30 meth/water ratio for about 3 months and then the meth started leaking out of my tank. All the rubber grommets and the washer pump failed. And my car is rather new (2010).

It's really worth taking the 30 minutes on ramps to run a trunk mounted tank, mainly to prevent the leaking issues, but also to run high meth mixtures without worrying about cleaning your windshield and potentially getting some spray in your face. It appears the WW location is more trouble than its worth as I am hearing the same complaints on all WW setups, BMS and Vishnu kits both.

I mean, what does a 1 gallon tank cost nowadays? $35 bucks, and $15 bucks for 15 feet of meth tubing? Should have no impact on how these kits perform at all. Well worth it in my opinion!

[mattsfeir]

What kind of range should we expect for the meth flow to input for Injection Mode? Are figures of 48 too high?

Does this mean I'm flowing more meth than someone with a setting of 30 or is it due to flow sensor variances?

If I set to 45, then I can make a pull without getting the 5 CEL's that I got at settings of 20 and 30.

So just to confirm Shiv, if I'm running m1/distilled water or pre-mixed JEGS boost juice then I'm safe?

Really? I run almost 100% for the past 6 or 7 months. If that happens I will re-evaluate if meth is worth the hassle at that point. Trunk mount is a pain.

now i'm starting to feel better... I read online though that methanol is highly corrosive to rubber and many synthetic polymers used in the automotive industry. But there are a few materials that can resist damage from methanol fuel. These include polypropylene, polyethylene and nylon.

hopefully those windshield washer rubbers are some synthetic rubber ...

Yep... No problem with either.

With most performance modifications and car's reliability in general, it seems to be the luck of the draw, roll the dice.

Windshield washer fluid IS Methanol.... and water. I am not sure why a higher concentration of Meth would start leaks. I just can't imagine that BMW would pick a product on the washer tank that would start to corrode the rubber knowing it will be subjected to Methanol - even if it is a lesser concentration.

Right. Well I'm not sure what experience you have with methanol thus far, but I can tell you since I have been running higher concentration 70% or more that I've had to replace a handful of things over the course of 3 years in regards to fittings and flow sensors. Many flow sensors are only rated to 70% concentration for a reason, as 100% is that much more corrosive.

So I'm not surprised if there are failures but yes if BMW wanted to do things right they would have made their WW system 100% meth compatible but not for us methanol users but from a reliability standpoint. I believe there have been some WW component failures regardless even with regular old WW fluid. I remember a handful of guys adding meth for the first time and finding their system leaking. I believe that is why we are seeing inconsistency as its the luck of the draw perhaps, or maybe difference in components/materials over the years.

I'm not a chemist but I believe there is a large difference in say a 20-35% concentration of meth in your typical windshield washer fluid VS 80-90% concentration what I run.

Be that as it may, as I mentioned above, roll the dice.

[rismo]

My ww pumps died by the use of 100%... also fitting of the ww resevoir did not survive it... Before I used 50-50 and 70-30 without problems...
Since then I only use 100% when I know I finish the volume on the same day.

I have noticed that my WW Fluid Level Low indicator light comes on when I still have at least half a tank of meth/water. Is this normal? Has anyone else noticed this? I've seen this a few times when I have had the wheel well liner off and can see the tank and my level low light is on.

Finally got around to loading these maps tonight. WOW. Seriously Shiv, good work. Once again, so smooth and so much sooner. Thank you.

Any chance we can get a list of oem items that may possibly need replaced due to running high levels of methanol in our ww systems.

Is the oem ww filter the only oem part that has the highest likelihood of going bad with this meth setup?

Thanks, I'm still somewhat new to meth.

IMOP the washer tank is fine if you plan to run 50/50 or even 70/30. I can tell you from experience, 80/20 and up are not recommended because the tank has an overflow which can cause a meth fire if your down pipes get hot enough to bring the Meth to its flash point. The overflow actually dumps meth onto the under pan. As the meth runs back onto the down pipes it will flash catching the under pan on fire. The under pan won’t burn, but the flame shoots up the side of the engine block. The foam under the engine cover is very flammable and will catch fire.

If you’re shaking your head and you don’t believe me, give Chris at HPF a call. He was in the car with me when this happened to my car. Lucky for me I knew what to do to put the fire out. If you slap the top of the engine cover really hard, the shock wave from the impact will put the fire out. When we drove back to the shop, we took the under pan off and sure enough it was wet with meth from the washer tank overflow.

Overboost wasn’t so lucky. He was running 80/20 when his car caught on fire and burned out the ignition wires and foam under the engine cover. Everyone assumed it was a coil pack that got too hot because only the foam under the engine cover burned. When he put his car back together he found the front axle boot was also melted. Overboost assumed there wasn’t enough fluid left in the washer tank because his dash light was on, but we all know that doesn’t mean the tank is empty, just low. The washer tanks don’t have safety foam in them like some race fuel cells, so the fluid splash around as you drive.

So with that said, if you want to run 80/20 or full on meth, buy a nice trunk mount JAZ PRO CELL w/Foam. The Junior Dragster fuel cell Jaz 230-001-01 or 230-001-05… Easy to install, comes with on/off valve, safety fill cap, aviation safety foam, and it holds 1 us gallon. Doesn’t take a lot of space, only 6x6x12 and it looks great.

Definately a good warning. I also fittied a fire extinguisher in my trunk when I installed my meth kit. Cheap insurance.

The fluid level sensor is located at item #1 of this picture. The level sensor is located at about the 1/3 mark. I have managed to drive for a couple of days even after the low fluid light comes on.

Wedge 1967,

Do you feel that 70/30 or less will not have this flash fire problem?

:Adding Water as we speak:

I already had one car catch fire about 10 years ago.

Thanks for this.... when it bursts into flames... can you just tromp it, get the car up to about 150 mph - will the wind put the fire oiut? (just kidding... adding water tonight - I was running probably 80/20.

[rismo]

Another tip: After I fixed my ww pumps and seals, I hoped that my level indicater would be back normal when filling up the resevoir.... It seems that also the level indicator sensor is affected by high concentrations on methanol.. 80% +....

Hmmm... hmmm...
