    Meth injection - questions!

    Hi guys.

    I'd like to know for how long can the meth be inside the tank in the trunk?
    Will there be fumes? Or does it depend on what mixture one is running?
    Do I have to change the meth lines to the charge pipe after x months???

    If there is a FAQ that answers these and more questions - PLEASE link it Click here to enlarge

    Indefinately. Some guys run a vent to the battery vent, I didn't personally. Change the lines if you see a leak due to chafing or any other reason. Being in Canada, I swap lines every 2 years since our weather is cyclical, and extreme.

    It can be in the tank for a while, there is no expiration, but I wouldn't recommend just leaving meth their.

    No fumes, some do run vent hoses, I personally did not.

    As long as you maintain your meth lines (which you have to do) you shouldn't have to replace them.

    Not sure if there is a F&Q but ask away

    I had a single CM10 nozzle and meth going old wasnt a problem I ever had. During two years the lines where fine, I did run the lines inside the car, dont recommend non-metal fuel lines under the car.

    I did have one leaking tank and hated the push-fittings, the tank was prob a first-production-batch error, never had issues with the replacement.

    So I just bought everything (Chargepipe with 1 bung though) Forge DVs, vargas stage 2 and I already got AMS intercooler and catless ardesign dps..

    I just want to remap my car to run like 1.4 bar ~ 20 psi or so as a dailydriver and go with JB4 g5 iso + meth for some rolling races if I get pulled on without meth Click here to enlarge Maybe run 23 psi or so.. I have the alpina b3s biturbo, so lower compression needs more boost.

    Is there any sticky or FAQ for the meth tanks?

    Actually, if I were to run meth lines, I'd run them outside the car right along side the stock fuel and vent lines (and brake lines).

    They are located under the drives side of the car behind the belly pan and the'll enter the engine bay right by your charge pipe.

    So you recommend fuel lines under the car next to the fuel lines and they should be in aluminum?

    No, I probably wouldn't go to the trouble of running hard lines.

    I don't play with methanol, but if it were me...I'd run PTFE lines and quality AN fittings. IIRC, there might even be an extra retention clamp along side the fuel line under the car to hold the methanol line in place.

    Frankly, if something damages the methanol line in that location, you've got much bigger problems than just a methanol leak because you'll likely have a gas leak and you're probably not going to be able to stop either. Click here to enlarge Also, as those lines enter the engine compartment they are also shielded by a metal plate.

    So it looks like the standard lines are fine for the meth application Click here to enlarge I couldn't see those pictures on the phone though

    There was at least one car here that had standard meth lines running under the car zip tied to the fuel line (I think) that leaked badly, this is why I ran my lines inside the car, seems safer and was dead simple to do. But there is no "right or wrongs" here, meth is probably a semi-safe idea at best anyways...
