    How to flow test and inspect your methanol kit

    Just made a "how to" video, looking for some feedback on it.

    Let me know what needs to be improved, at least to help some people that are new to meth kits.

    Im not familiar with everything available these days, but I still see a lot of meth help threads. I was doing my own today, and figured I might as well tape it.

    Of course, if you need the other parameters of the guage, you will want to watch that as well.

    +1 an external mic would help the gopro record better sound quality!

    I do it old school, take poland spring bottle or measuring beaker, test spray nozzle(s) for 30 seconds, ballpark estimate it

    Nice video, but take the water proof case off next time bro. Like the guy above said it sounds very muffled. I can turn up the volume and hear your voice a lot better but the camera noises get way too loud.

    Why did you put this in N54?

    yea, but a lot of people didnt know what exactly to do. most assume you need a compressor, and all sorts of special equipment.

    I forgot I had that case on it, so yea, sound was lower than it should have been. Ill remember it for next time

    more n54s on meth than any other. move to wherever you want. it would probably help s65 people more these days though

    Cant speak for LM, but its probably because the majority of us run meth.

    Lol take smartphone of choice, turn on stopwatch count 30 seconds or a minute measure meth flow.

    Can't see the video at work, but I know guys who were benching at 12V. It's important to flow at 14.4V if you want a true representation, though not many people have a bench power source without turning the car on.

    good post. I'll be upgrading my meth kit this weekend, I'm definitely going to test it out using the measuring cup method.

    Critical point here, but the point source voltage is usually closer to 13.8v

    The alternator is regulated to 14.4v...but the power goes back to the battery, then through the power distrubution system which results in some loses. (There are actually more loses from going "through" the battery than through the distribution system)

    I have a regulated 40A power supply for doing this kind of testing which I find a lot better than using a digital 12V battery charger. (Tighter voltage regulation)

    All you need to do is run the engine though and you've got a "real" voltage source. (Plug the boost line port)


    Again, great "how to"....I wish more people would take the time to do this type of stuff, even if the sound is a bit hard to hear. Click here to enlarge

    little things that i find myself looking for, or when other people ask me about, id like to show Click here to enlarge

    Question, so, if voltage was low, that affects the pump speed and COULD be why i was about 100ml/mn low right? or is there something im missing?

    Pressure is usually regulated at the pump by a blow-off or recirculation valve. If this is the case with your system, and it is with mine, battery voltage will not affect flow until you get up close to the flow limit of the pump.

    Lets say the pump can flow 1600cc @ 13.8v, and 1400cc @ 12.8v. Voltage will have no effect on your system flow if you are only using 800cc.

    What I've found is that fluid flow and pressure is hugely affected by fittings and transitions. Those little 90 degree plastic push connectors probably decrease flow by 10-15% each. Also, depending on the line length from the pump, there will be some flow losses there.

    The best way to test what is really going on is to have a pressure and flow sensor right behind the test nozzle.

    Some of the better systems on the market account for some of these flow losses as an average when designating flow rates to nozzles, but they can't account for everything.


    Something I did with my 330i was run -4AN line and fittings with smooth bend radiuses. The point wasn't to increase flow potential, as much as keeping system pressure higher at the nozzles to help with misting.

    If you have the flow volume you want, it really shouldn't matter about all those bends....

    XRP has some data on this towards the back of their catalogue which can be found here:
