I have reads a lot about how great Meth is and all the benefits but I dont hear much about the risks. I am a complete newb to this world and dont know much at all but from my research i have found its like using race gas and lowers the temp. of the engine at the same time. I obviously have to do a lot more research but wanted to know the risks. I would do it where I would connect it to the JB3 so that the JB3 would change maps if there was a shortage or cut in the flow. I also would get the gauge so I could watch the flow rate. I just see how it seems like everyone is doing it and had seen all the benefits but not the other side to the story. Thanks

i dont know much but here is what i do know:
1. it is HIGHLY flammable, so any kind of leak in the system is very dangerous.
2. you will have to constantly buy meth and refill just as you would gasoline

I didn't know much, but the magical search button told me everything I needed to know.

[vase330]

Very helpful!
Care to elaborate? Not for me, for OP. Why? I don't want a habbit car is fast enough without it for all the legal roads I can find in the US.

[kennejp]

I HATEEEEEE when people refer to saying search. I have been on many forums for many years and always give helpful advice. If you dont have anything to contribute dont type anything. I said that I am a newb and am doing research and even stated I have a ton more to do but most forums are on benefits and installation not risks and downfalls. Thanks

The 335 is pretty shit fast without Meth. Maybe I'm crazy.

Meth can potentially be a fire hazard in your car if your system is not properly installed or you develop a leak. If you run a water/meth combo (almost all do) you'll need to change your oil more often as water contamination is a distinct possibility. You'll need a tune to take full advantage of a meth injection system. The tune + meth will make more power which WILL shorten the life of your engine.

That last issue is fairly complex as some mods, meth included, are actually "healthy for the engine.
-Downpipes reduce exhaust pressure making life easier on both your engine and your turbos. All engines are essentially air pumps. Make it easier for them to breathe and they'll thank you for it.
-An fmic reduces charge temperatures ultimately allowing for tighter timings which means less heat lost to the block and head. Heat kills stuff via thermal cycling/fatigue.
-Meth will keep those intake valves nice and clean

With all of that said, if you had two identical N54s on the bench, one tuned for 300bhp and one tuned for 400bhp, at the very least the bearings on the latter engine would give out sooner.

Pay to play, no free lunch, that's the bottom line. Life is short, I say play but ultimately YOU have to run your own intertemporal analysis of the costs and benefits of
modding your car.

bad.

1. its highly flammable

2. it hard to uninstall for service issues

good


1. better benefits than a upgraded FMIC

2. cheaper than race gas

3. safer than Nitrous
____________________________


All in all its a great mod if you aren't scared of the risks because its dangerous but its just as dangerous as running a tune. their is a risk of doing any type of performance mod to your car but people still do them because either they like speed or its a hobby, for me its both. But dont do a mod that will bother you because its dangerous do what you are comfortable with.




BTw if you get everyone to stop saying search your a very great man becuase its almost impossible. Welcome to E90post.

a 2.5 gallon tank and you will not buy Meth that much. Plus you mix it with distilled water. You add a Meth kit to run race maps on pump gas. Therefore you SAVE a shitton of money because racegas is 9$/gallon and Meth is 4$/gallon and you can do a 50/50 mix which brings cost down even more. You only use Meth when WOT or close to it. So an 80/20 mix (being generous on Meth use) in a 2.5 gallon take would be 2 gallons of Meth which could cost you 8$ and could last weeks.

I think Meth is the best mod you can do after a tune. You can be running 116mph+ with only Tune, Methanol, intake on pump gas everyday. Who cares what you trap on racegas as it's just a glory number and not a real-world everyday number.

Isn't Meth Corrosive? Can anybody speak to how corrosive it is and which part of the car does it affect?

It is in liquid form. You have to understand this is vaporized almost instaneously. There is never any liquid that will sit on the inside of your engine.

[huyner328]

I've even read that it cleans your engine!

It evaporates almost instantly dude so no worries.

here's a Quote from cooling mist..

If so, every one that has torn apart an engine would have noted this and you would be hearing alot of people complaining about it. There is a reason you hear alot of people asking the question about meth being corrosive, yet not very many documented cases (I have yet to see any).

To be clear its 100% fact that meth is corrosive to viton, alumimum and most rubbers (EPDM and BUNA-N excepted), however it must be in constant contact. The flash vapor combined with the heat of the engine and air flow make this a non issue. There are more important things to worry about.

FYI, dont make a customer alumimum tank for your meth. If you plan to, make it out of plastic or stainless steel or it will pit and corrode the tank.

downfall of my Meth...........it runs out

[Kroy]

downfall: prone to excessive speeding

[cn555ic]

the gains outweigh the risks....only risk really is that its flammable, but if its installed right the chances are minimized

[GreenPlease]

You'll get crappy gas mileage because you'll be flooring it as often as possible.

Your traction control light will be flickering a lot

why is everyone saying it flammable?
if u use a 50/50 mix its not flammable so its not dangeroues at all
and even if you were to use 100 percent meth or anything higher than 50/50 what are the chances of it being caught on fire? i think pretty slim
but other than that...
Increase horsepower obviously, Lower air temperatures, Reduce cylinder temperatures, Allows you to safely run more boost and timing, Removes carbon build up from combustion chambers, Increases octane when you need it under boost

That is wrong. Let's make sure we are using accurate information. Light the 50/50 methanl/water mixture with a match and you won't see a flame, but put your hand over the mixture and you will indeed see it is on fire with an invisible flame.
