Hi, i was just wondering why i have never read of a gtr running meth? I have it in most of my cars (evo, sti, diesel trucks and suv) . Am i missing something?

 

[paparazzi]

This has been raised before. Aquamist in conjunction with Akuma brought out a GTR specific kit but for one reason or the other it never really took off.....if it did nobody's really giving feedback.

Maybe the Akuma boys can chime in

I'm using this in my car. Running 100% meth and have run into no problem whatsoever. It lets me to run 4-5 points of additional timing through the rpm range @ 22 psi. That's my low boost setting and have picked around 50-55 whp and 70ish wtq with the addition of methanol injection. here is a picture of how i installed it in my car located on the right corner (the tank in white color is the methanol tank and behind the tank is where aquamist pump & control module) :

Conclusion: As long as the system is properly setup and maintanenced (proper installation, proper check up for line defects etc), it will add some safety margin for the engine and yield net power gains. It gets more beneficial for people that has no access to premium fuel (anything above 92 oct)

Risk Reward. If any single component in the methanol system fails then you risk engine failure. If the system works flawlessly, then you gain 50 hp.

Not much reward for that type of risk.

Better options exist to gain 50 hp. Just my opinion though.

We have a few running our Aquamist kits. The new kits are actually very affordable...$550 plus install. They are good for 50+ HP depending on mods and tuning(possibly more). The Aquamist kits are very good and no other kit comes close in the market.

I can get you pics or install details if you want them.

Regards,

John

@heacuva, why do you need to run 100% meth? I understand it is bad for the pump and seals? Do you do it for additional fuel or for cooling?

IIRC, if you tune your car with the meth off, this will make things safe in case of meth kit malfunction, but I'm not very sure bout it. I really like the cooling effect of the meth kit. It really reduces exhaust temps.

Wow 550.? I got mine in may for 900. ++ minus the tank. What model is this and is it easy to install? The low end devils own and aem were easy because they were either voltage or boost controlled. But the aqua mist is kinda tricky to install. I had to take it to 2 different shops before they made it run properly. Can post pics? I might be interested in a kit for the gtr, thanks.

Agreed. This method is safe.

Heacuva's method might be a bit more risky if a component malfunctions. Probably why the caveat is "As long as the system is properly setup and maintained"

Seems there are just safer ways to gain 50 hp. Might I be alone in this thinking? Possibly. But I doubt it. Then again, a 2012 only costs 90K.

@sleeprz, i also agree, plus when doing long drives you need to pack extra meth with you which occupies more space in the small trunk. But then is also nice to have it

if we are talkin about hp/$, no you don't have any other option that will give you the same power for this kind of price.

talking about part malfunctions, gladly the aquamist system comes with a in cabin gauge where it visualizes the status of system components and gives you an error message in case something is wrong (like methanol level getting low etc)

can the pump fail? yes it might fail but you won't be blowing your engine because of a failed meth pump. Worst you would be seeing is the boost gauge flashing due to knock. If you fail to see that probably you shouldn't be driving a modified car as you might get the engine blown just because of a bad gas you got just because you didn't see the boost gauge flashing (assuming you are running cobb ap). make a search about failed walbro pumps which most of us are running. you'll see more failed walbros than the failed aquamist pumps. which one would be more dangerous for your engine when it decides to die @ 18+psi and 6000 rpm? Clearly your fuel pump but still we are using them because the odds for fuel pump failure is low. so is the meth pump dying. i said the system should be properly installed and maintenance is required because this part is a bit more complicated to install than your avarage midpipe so its better to make sure you have someone with the knowledge to install this part.

also the cobb gives us the option to run several maps. i'm using map 0 for when i don't have the meth injection online and running map 1 & 2 for meth injected maps. that gives me the option to swtich the meth kit on and off whenever i want.

running out of meth? unlikely. i tracked the car for 1:10 hrs last week to get the meth finished. should give you an idea about how long it takes to dry it off.

i believe the aquamist system is stated to be safe for running pure meth.

I'm sure your system runs well for you. My post was not a knock on your specific setup. Cheers to you for having figured it out well. Didn't mean to offend you.

I'm more referring to others who might see this post and advance there timing by 4 or 5 degrees and run 22 psi, simply by adding a "meth" injection system. Hard to do without a tuner though, but there are many incompetent tuners out there. Yes Walbro pumps fail, but there are a much greater number of walbro pumps in service compared to aquamist pumps. So if they failed at the same percentage, you would hear more about the walbro pumps. But other components can fail as well. Low volume sensor, clogged injector, valves, leaking lines. etc... The ecu doesn't pull back the timing or psi if any of these components fail. It may just wait until knock is detected. The question is, how much damage has occurred until the ecu responds.

This was the risk I was referring to. Just seems like dollar for dollar, even just getting a tune from a site sponsor without other supporting mods might be a safer route. Again, just IMHO. That is why I surmize you don't hear about many meth systems on GTRs. And that was the OP's original question.

I have the aquamist system installed by Akuma. I run a 4parts meth to 1 part water mix, and John used my windshield washer fluid tank to hold the fluid. I have run the system since about June and it has been great. A little light turns orange and lets me know that I need to add meth, and it blinks green when the meth is being injected. Seems simple enough. Not totally sure I see 50whp from the set up, but that may also be because I am not running 22lbs of boost.

I will not speak for John (Akuma) but, he seems to tune for the safer side, opposed to more aggressive. I believe that I was running 19psi, and he was talking about upping it to 21psi. Hopefully I will have the car back from the dealer today, and John can send me the new map. Going to hopefully take the car to the drag strip next week.

As far as Akuma goes, they have been really great to deal with. John explains everything, and pushes NOTHING. He will educate you as to what your options are, and then you direct him from there. My experience with them has been great.

Not offended at all mate, sincerely sorry if my post gives such an impression but my aim was to share my experience about this modification. Probably should have used more emocations lol

By the way its not likely that a few occasional knocks will kill an engine(unless you are drastatically pushin the setup over its limits), that happens even while tuning these cars. Danger lies when it happens repeatedly due to some bad tune or pushing the car over and over again while seeing it knocks

Agreed. Sagligina!

Haha cheers mate

Hey john, can we run 100% meth on the aquamist kits without fear of damaging the seals and pump? Thanks

 

[alexdavis]

What are you using for your source for methanol?

Alexd

 

[EVO killer]

Alexd, what do u mean by which source are u using for methanol?

 

[alexdavis]

Alexd, what do u mean by which source are u using for methanol?

Purified methanol from a chemical supplier? Industrial methanol from a hardware store? Winter window-washer mix?

I.E., what are the supply considerations, if any?
