Hey i have been searching for an evo to buy for a while now. i found one i really liked but i noticed that it had a methanol tank in the trunk. now i was just wondering but i dont know anything about meth injection. is this bad for the car? especially on a daily driver? does meth actually destroy the motor? or is it fine to run? i talked to a friend and he said i can always just unhook the nozzle and hook it up if i randomly want to run it. but if it does no damage and is ok to run then i dont mind. please any advise would help. the car has basic bolt ons a tune and this meth injection. i had a mechanic look it over and he confirmed that it was a good install it wasn't rigged or installed poorly it was a good job. any advise would be great please help thanks!

 

I dont know too much about meth injection either, but i do know that as long as it is hooked up right it isint really bad for a car. Also the meth isint physically injected in the motor until you race the car. Meaning if you shift at 2500 your not going to use any meth, but if your constantly red lining your going to be filling up that tank in the trunk quite often.

 

ahhah yeah i know what you mean. well the guy did say the tank last a good bit. but is it bad to run with the meth hooked up even if its empty? and i know for a while since i have driven a boosted car that for atleast a week im going to enjoy the **** outta the car haha. but i mean i guess im just wondering what exactly is meth? like if its not bad for the motor what does it do?

 

meth doesnt destroy anything.... bad tune or failed part is most likely the reason for anything to fail.

when meth is setup properly, its very safe to run

 

really? thats good um but what exactly does it do? and how can i tell if it is set up properly what would i look for? the dealers mechanic said it was hooked up good but i would like to check my self

 

I dont think you can really hook it up bad lol but like someone before me said, its all about the tune. If it has a bad tune then it can be bad for your engine, but a bad tune can mess up your engine even if your not running meth. Also yes, it is bad to run your car with the meth tank empty, is just like putting regular gas in an evo thats tuned for 100oct. You'll get huge amounts of detonation.

 

ahhh. well how ofter would you say the tank will stay filled for? and were do you even get meth

 

Meth is a good thing and bad thing, it is a good cheap way to make alot of power, its bad because unless you had direct port injection then it is impossible for each cylinder to have an equal amount of meth thus cylinder #1 in most cases resulting in catastrophic damage and a dead motor due to cracked pistons.

Even with the proper failsafes in place this can happen.

As for running the system without meth in the tank you would have to make certain that the system electrically is shut off because dependent on what kind of pump you have in the car you can very easy fry the pump if you run it when it is dry.

I had meth in my car up until my recent build that I am undergoing, my rebuild isnt the result of meth failure, I was fortunate enough not to have anything major happen to my motor thankfully but I have also decided to turn away from it because E85 is around here and if you have a heavy foot you will go through meth very quick, a couple of good runs 10 min or so of a heavy foot and you can easy fly through an half tank or more.

Its fun but in my opinion now since I did have it your really playing with fire if you dont have a direct port injection to insure even distribution.

Do some searches on this, Mike from AWD has posted countless times about getting motors in his shop that are blown due to meth injection, its a pretty scary sight.

Even if the tech who looked at the car you are looking to buy says its good to go you never know whats lurking inside the motor unless he takes it apart, it would be horrible to buy it and somewhere down the road have what happened in the link happen to you...

 

^ not entirely true. Mike's thread has been determined to be biased and one sided. All fuels can be dangerous if not tuned properly.

 

what if it is directly into each cylinder is that ok to run daily? and if i were to have it taken out how much do you think it would cost to take out and like have tuned down i guess

i dont know if it helps but here are pictures of it dont know if it will help

polish_pounder, answers like this is what creates panic and misinformation. Go on and click that link and read it through from the beginning to the end. You'll see posts from me and a number of experienced water/methanol users.

Now I would suggest that you really educate yourself about water/alcohol injection before you fill that tank and start going WOT. Read alot threads on the water/alcohol section of Evom. Search the internet. One of my favorite and very informative sites is the Aquamist site:http://www.aquamist.co.uk/. Join their forum, it's a wealth of information. Also ask the previous owner what kit he had installed? What brand methanol he was running? Was it 100%? Was it a water mixture?

An educated, well informed water/alcohol user is the only way to make sure you keep out of trouble.

 

I cant tell from the pics if it is a direct injection kit, if it is there should be 4 separate injection points usually for each runner located in/around the intake manifold. If not then the injection point is probably in the UICP

What kit is it? Is it an AEM kit, im just guessing based upon the 5 gallon meth tank that is in the pic.

 

I didnt provide "misinformation" if you actually read what I wrote rather than trying to pounce on someone then you would realize that I did say it was my own opinion and I dropped that thread for him to read to make his own educated decision.

That is how Mike@AWD kind of started his thread. An intro to scare. Not trying to pounce on you. The rest of what you wrote is right on. We all trying to help the op .
