Methanol injection

[Greenie]

Kind of been thinking about a methanol injection kit for my car, just wanted to get some feedback and where to buy it from or if its even a good idea.

how much boost do you plan on running? A meth injection kit will increase power and give you lower air temps going into your car as well as reduce knock and emmisions(like anyone cares..) id recomend the AEM one, it is not a bad system at all for the price. here is the link to aems website with some information on the system, hope this helps you out!



AEM Water/Methanol Systems for Gasoline Engines - Water/Meth Kits - Wideband O2 UEGO, Water/Methanol, Stand Alone Engine Management, Piggyback F/IC, Tru Boost Controller, Gauges, Automotive Performance Electronics

planning on running between 14-18 psi around town

planning on running between 14-18 psi around town

meth injection will increase power but at that boost level its not really worth it.

at that boost level a NOS kit would be a better injected power adder.

Yea, meth injection won't get you much with boost that low... I have the AEM nozzles; they're great because they have the check valve integrated right in with em at the end of the line, so you get minimal leakage/drainage after you're done spraying.

I thinks amazing I've seen a guy run it on the dyno with it and then with out it. It works wonders helps to keep temps lower, free from det.

i have the aem kit and the only thing i don't like is the controller . they should of had dials to adjust the low and high boost settings other than that it does its job . i have the largest nozzle and run 27 to almost 30 psi seeing only .07 counts of knock . last pull i did it showed 401 hp with 44lbs of air through mass air sensor.

Also running a small nozzle pre turbo can move your compressor map over.

I fitted the Devils Own Stage 2 progressive kit to my old Evo III and it was the best bang-per-buck upgrade I did. Wrote a review of the install here:

The only downside is that it does add another point of failure. If you're at WOT and the meth packs in for some reason, you might be in trouble.

Run more boost before considering a meth kit.

I personally would go with an Aquamist kit.

 

[spadepro22]

At what amount of boost should you start thinking about meth inject?

 

[ariman]

^^ what is the best moment for to start meth inject with 28 psi

 

[cl1ckclack]

A lot of it really depends on the fuel that you are running, and how your tune is. Personally, running on 93 octane, i wouldnt want to run any more than 20-22 psi in my daily driver without it.

It's dependent on the car's set up and tune.
You really need to start tuning and see what your max is.

 

[Black'95]

I ran around 25psi without it, but everyone's setup is different. Right now, mine's activated by DSMLink, and I think it comes on around 17-18psi. Without the meth, I was only able to run 6* max timing, and spraying about a 50/50 mix with a single large AEM injector, I was able to run 17* timing. Quite a difference, I tell you!

 

[bradselph]

like i and everyone else said your not pushing enough boost to heat up the air enough to really need meth injection. will it still make more power with it yes, is it worth it at the boost level your running probably not.

now in my case i need a kit because right now im pushing 24psi at 45-46 lb/m on 93 octane and max timing at 8* before i get knock

Also running a small nozzle pre turbo can move your compressor map over.

You aren't worried about the damage to the compressor's blades?

My 50/50 system was at the throttle-body elbow for exactly this reason: do not inject anything until after the CBV so that there's no chance of any water droplets hitting the compressor's blades. I would also avoid anything that might allow a pool of water to form in the intercooler.

 

[Blurred Talon]

^ I would only run 100% water pre turbo. Meth can eat away at the turbine wheel.

Aqua mist makes an.....adapter let's call it that allows a nozzle to be aimed perfectly at the compressor nut. There's a big thread on the Aquamist forums about pre turbo injection.

 

[boost97gst]

I can see cooling the air pre turbo helping overall IATs. However the risk/reward probably isnt all that great. Cooling the IAT, no matter how its done, or at what boost level, WILL make more power. Its just not necessary at lower power levels IMO, the gains would be minimal in theory.

years ago we had a dyno day and i installed 6 of these kits on a evo in one day

aem has an updated injector nozzle v3 and it works great. my knock almost totally went away at 30 psi of boost. there is a video on it check it out .

 

[Lou98GSX]

i am glad someone finally saw my post cause that new meth nozzle design atomizes the meth better . i have seen close to 32 pounds of boost with 0.7 counts of knock on a 2nd gear pull .
