looking good either way. I want to do that to mine. i got a 99 limited. my friend put a supercharger on his tacoma and loves it!

 

It was the best thing i did to my truck so far thats for sure. Totally changes the way it drives.

 

Just got the new Meth kit in today!

Looks pretty good, now just got to install it and wire it up then we can see how it works.

 

Well, got started on the meth install today, most of the day was spent on trying to get the new controller to connect to my laptop. Seems my USB to Serial adapter doesn't like it.

Rigged it up in the house and it connects fine to the desktop. So ordering a new adapter but gonna go ahead and finish the install of the main unit now, It should work at least good enough to get me running again and i might play around with using the MAF voltage instead of the smart controller to see how that works, have a feeling it will go rich in the mid-range but i could be pleasantly surprised and that would make the setup cost a lot less for the rest of you!

I already know i won't knock even with no extra fuel up top and AFR's in the high 13's, heck it doesn't even pull timing but for peace of mind i would like them to hold a bit more steady up top. You would be fine with using the CMGS or possibly some other meth injection kit that can use a MAF voltage, heck even my AEM did the job just not as good as i like.

I think this setup will work out pretty nice once I get it finished. Like always will keep you updated.

Oh, i also now have the CM10 nozzle, so i think i will be putting together a video comparing it to the Devils own and AEM nozzles i have as well, see how they really stack up.

 

Got the new Serial adapter in today, this one works perfect, if anyone needs one i highly recommend the Keyspan unit.

So i can start working on the install over the next few days now that it is supposed to warm up.

Oh, i also decided to put in some more water in the meth injection to see how power was effected. Once again Meth makes WAY more power then water. After i get the new setup finished gonna do some more official testing of timing and such with different mixtures.

 

Well got the new meth controller wired up today, gonna finish up the install tomorrow most likely.

Found the first thing i do not like about this setup, for some silly reason it does not come with a mounting bracket for the gauge, forcing me to have to spend a half hour+ making a custom bracket vs them just stamping out a 10 cent bracket for them.

Not smart IMO seeing as all 52mm gauge pods are basically the same and will use the same basic mounting bracket. Every other guage i have every had (and thats a lot) comes with a bracket and not had a problem yet with one not working.

/End rant

Besides that though the install is pretty straight forward and not that bad. Will see how it works once i finish.

 

Basically finished up the install today. Got all the old 7th injector parts removed and finished all the wiring ect.

Decided it was not worth my time to make a bracket for the gauge, so I just broke out the hot glue gun and glued the sucker in.

Also made a custom EGR blockoff plate that i now have the meth nozzle installed into.

All thats left to do is check it over and then run the new lines for the meth nozzle.

Will make a new thread tomorrow most likely detailing all of this and showing exactly what i bought and how to do it yourself.

Also did some testing with a few different nozzles today, got a new youtube video about ready and gonna do some testing with meth vs water vs washer fluid.

 

Got the meth kit install finished today!

Started playing with it some and have to say i think it is going to work perfect!

Will make the writeup tomorrow after I can snap some pictures and post all the details then.

I also did some testing before hand with using pure water to see how the knock was to know if it is safe. Cause i know that some people will say they don't want to do this because they can't get pure meth or it costs too much ect.

The good news is that even with pure water I got ZERO knock at all and I know my EGT's were lower from prior tests on other cars.

AFR's got as lean as 15:1 but the ECU was actually running MORE timing then before. Now it was not NEAR as fast with this setup but it is safe and backs up what i have seen in other tests

So using plain water in a pinch is NO problem at all and would be safe.

You could tune it and set it up to be safe with basically any mix of water/meth. The more meth you use the more power you will make though but you will be safe either way.

Seeing as washer fluid is a whopping $2 a gallon, it is cheaper then gas! and the more you inject of it the less gas you are using. This would make for a perfectly safe setup to run every day.

For those that can get pure meth, they are in for a real treat!

I am VERY VERY happy with my choice to ditch the 7th injector kit and go with the meth injection.

The 7th is officially for sale BTW, all pulled off the truck and good as new.

 

Oh, and for those asking i can also confirm that even down on power due to running on pure water my 4runner is a fair amount faster then a new VW beetle up to i had to let off since my tires are not exactly up to high speed runs.

 

Thats very exciting to hear!!! I guess i will be diving into the world of meth injection after all.

 

At what throttle position did you get 15:1? Because if it was WOT I'd hardly call it safe. Also keep in mind every truck is different, to say its safe in every different truck based on testing in one is just plain reckless IMHO. I just caution over-selling this.

 

Yes it was at WOT and yes i stand behind it being safe with the 10gph nozzle i have.

There have been MANY tests over the years showing that a fraction of the water i am injecting can make it safe to run WOT at AFR's of 14.7:1. I posted one of the links earlier in the thread i am pretty sure.

Anything over 15:1 actually has lower EGT's and as long as it is not knocking there is no damage being done at all.

It is not knocking for sure, the ECU was running MORE timing (peak of 22 degrees vs 21 and a few more degrees everywhere else as well) and EGT's should be much lower as well.

The only damage that comes from running lean is

A: knock

B: High EGT's

With a nozzle of around 4gph people have ran 14.7:1 and more timing then stock with no knock and lower EGT's.

I am running a 10gph, with that much water I am positive that my results are better.

I know of a celica that is running pure water in a higher HP turbo car and tuning for 14.7:1 across the board under WOT on purpose and has no problems at all, and he does have an EGT gauge. His EGT's are lower under WOT with water then they are cruising down the highway. And no knock at all.

So i do have facts backing up my statements, I have done a TON of research on water/meth injection over the years, it has been a pet project of mine (as shown by my mother of all meth injection systems for my MR2, over 8000cc of meth being injected, literally a garden hose being pumped into my engine).

That said, pure water is only for those in a pinch, Like taking a trip and running out or something. In a pinch it is perfectly fine to use to get you where you are going. I don't recommend it on a daily basis when you can get plain blue washer fluid for so cheap and it will add fuel as well.

Pure water also has a LOT less power then meth so no one would want to run it unless they had to anyways.

Washer fluid or a 50/50 mix i DO fully recommend, i will do some testing later today with it to see what it does before moving to pure meth. With it you should be able to keep AFR's basically in check and there will for sure be no knock or EGT issues.

Now the best option is obviously pure meth, it will give the most power and work the best for sure. This new setup is fully tunable and progressive allowing me as much control over the injection as the 7th injector only injecting meth instead of gas.

It is basically the same setup as the 7th when you think about it, only it does a lot more then just add fuel.

 

You will not regret it, having gone back and forth between meth injection and the plain 7th a few times in the last few weeks the difference in power is VERY noticeable. It also just seems happier with the meth.

 

So what EGT are you hitting? I often hit 1450F and sometimes a little over and that's with water/meth injection and a good tune.

 

I don't have an EGT gauge on my truck, never said i did. But going off of past results and many other tests i have seen with the size nozzle i have the EGT's are gonna be no higher then a proper tune.

Like i said, I have seen lots of cars running pure water injection and running at 14.7:1 AFR's have lower EGT's and run more timing then stock. I see no reason this engine would be any different. I know for a fact it is not knocking, EGT's I am assuming are fine.

I actually do have a test for EGT's of sorts. My headers run right by some of the heat shielding in the engine bay, when i was on the 7th kit after a hard pull if i pulled over the heat shielding would be glowing/smoldering due to the EGT's.

Since going to meth injection that has not happened since. I checked it last night as well to make sure, did a hard pull then slammed on the brakes and checked it out. Not a hint of high EGT's the heat shielding was not even effected.

So i am pretty sure the EGT's are at least lower then they were with just the 7th kit.

You also have to remember, i am NOT recommending pure water in this setup, only stating that it can be used in a pinch to get you where you are going. I am recommending a 50/50mix/washer fluid as the lower end of the scale or pure meth as the best option. Those will work great.

What size nozzle do you have? That plays a big role in it.

 

I'm using the Aquamist 2d system with a .9mm nozzle. I also have a .8mm and 1.0mm but the .9mm seems fine for my setup.

 

The 2d is the old style pump right? the one that is low pressure and low flow right? Came out of a printer or something IIRC.

With that nozzle and pump you only have about 65psi of pressure and 300cc of flow tops. That is a BIG difference between 250psi and 800cc+.

If i was running that setup i would not even recommend running it without the 7th injector at all weather it is pure meth or any mixture. That type of setup is purely for added safety for an already good tune. Plus that pump will simply not flow more then ~350cc IIRC.

The setup i have built is literally years ahead of that one, aquamist has since got rid of those old style kits since they really are not that great and use a setup basically exactly like what i have now.

I guarantee you that if you upgraded to a modern meth injection system running a larger nozzle you would see more power and lower EGT's.

Your setup is fine for a safety net for an already good tune though.

Water is better at lowering EGT's then meth BTW.

 

Out of a printer??? WTF

This is the pump, yes I'm also using an accumulator:

 

I know the solenoid in the old Aquamist kits was out of an inkjet printer, it seems like the pump was as well but not real sure, it might have been out of something else.

The pump itself is a lot smaller, most of that is just heat sinking they added to it so it would not burn up.

It was out of something real odd though and once you knew what it was no one wanted to use it anymore which is why they had to change the kits to the modern design using the shurflow pumps once it came out what the kits were made up of.

Either way, like i said it works fine as an add-on to a good tune but would not work in a setup like i am talking about by any means.

Oh and also a note about running pure water. I used over 2 gallons of water last night while playing around, much of it at WOT and no issues at all. I beat it pretty hard too.

 

Yeah I wouldn't dream of using just that for my fueling needs. I also run 6 318cc fuel injectors.
