Hey guys. I am really considering doing meth on my car here soon. My main question is if there are no down sides and meth is supposed to actually be good for your engine how come more people arnt doing it? Seems like this would be done way before you would get dp's or intercooler as it takes maybe 2-3 hrs to uninstall at max and gives you more gains then both fmic and dps combined when on jb3 or procede tunes. I just dont know why this isn't one of the first mods after tune and intake? The guy the other day was putting 410+whp and 430wtq with procede/intake/meth.....

[zsapphire7]

because DPs and FMICs are still good supporting mods to reduce the stresses on your turbos maybe..

[Jeff@TopGearSolutions]

Most of the reason is for lack of knowledge of how it works, install etc etc

Soon as I had someone show me how its done, its so "simple" to me now.

AS long as fail-safes are in place its very safe.

[kennejp]

That was what I thought that it might be lack of knowledge. But everything I am reading is that all it does is lower your temps and allows you to run higher boost and more aggressive tunes because of it. It seems like a pretty straightforward install and would be a TON easier to remove then the dps and fmic

[cuban335i]

its scary



lol jk but i don't know why i didn't install it... i already have a shit load of stuff on my car and its already going to be a bitch to take off for warranty work so that's probably the main reason (not to have something else to take off)... also, i don't drive my car that much at all so i wouldn't want the meth just sitting in my trunk for long periods of time..

Doing DP's, exhaust, fmic will put Less stress on turbos. They will last longer.

Lets see:

1. It fucks up your oil. You need to change the oil at least every 2500 miles.
2. You constantly have to refill the meth tank: can be costly and/or time consuming to keep making your own mixture.
3. If you get the mixture wrong it could be damaging to your engine parts. Meth corrodes aluminum on contact. Also, this is not a direct injection. You are spraying inside the intake tract, which means sooner or later meth will hit the aluminum of your engine components.


I'd venture to add that I am yet to see a long-term survey on the effects of meth injection on the emission systems. I am leaning towards the idea that meth may be detrimental to catalytic converters on the long run

A little exaggerated but good points.

2500 miles is a little extreme, most get away with 5000 and find no problems in their oil.

As far as "constantly checking" I pop my trunk everytime I throw my gym bag in the trunk, a quick glance is all it takes. Probably last 500-700 miles

Get the mixture wrong? What is the wrong mixture? I run 90% methanol. You're talking about aluminum charge pipes or similar? Do you know how many years of methanol that would take? Maybe decades.

At the end of the day between emissions cats and long term, I'm not keeping the car long enough to worry.

[kennejp]

Ya that seems a little exaggerated to me to. Cant take more then a few min and not much money at all to fill the tank. And seems like a little excessive at 2500 but even so I did it every 3k on my built e36.

Cost me $4 gallon to fill up my meth. No complaints. My meth tank gets about 650 Miles a gallon like I said.

This discussion just convinced me to do Methanol Injection along with my FMIC and DPs.

Uninstalling is the main reason I have chosen to stay with meth/intake/tune. It really isnt that hard to take off and especially if you have a dedicated meth elbow.

[oc_bimmer]

Just go for it. You won't regret it, I promise. Meth is the second most important mod for our cars (after the tune) IMHO.

I only have jb3, DCI and meth, and I run on race maps (map 8)

My car loves it. I only have to refill my meth tank once a week. Absolutely no big deal.

It won't destroy your engine. It'll only benefit from this mod. Meth will evaporate and burn immediately in the engine, and won't contaminate your oil at all.

If your paranoid, change oil every 5000miles as others suggested, but this risk is more just a myth.

Has anybody heard of a corroded/destroyed engine block that was caused by properly installed meth/water injection? Me neither.

+1 and if you can stay out of the throttle you will use it very little. Ive had a few weeks where i havent really had time to take my car out for fun and I didnt have to refill for 2 or 3 weeks. I have a relatively small tank aswell.

[scottp999]

More people will be doing it, it's just getting past the early adopter phase. I just did mine a few weeks ago after I saw some others report good things.

I don't see any downside with the safety features built into my tune and the logging I've done to get the settings good.

[OpenFlash]

+1
As much as I hate building PnP meth kits by hand, I can't think of a better mod after the tune itself. 100-120whp gains with just a tune, DCI and a meth kit. For what, around $2000?

No real downsides either. If it runs out, no biggie. The tune will just dial itself back until you fill up the tank again.

im still trying to understand it, maybe one day

[BoostedCosta]

Why more people dont do Nitrous first?

[themyst]

Because it costs more to do

nitrous kit, clutch (for 6MT), filling the tank, etc

[kennejp]

lol those dont work the same at all!!!

notrous kit is the same price as a meth kit
cutch is expensive but not needed in a AT
filling th tankisnt too much...$60
so there! lol
