umm, if you mean "torque converter", no of course not. i inadvertantly used TC for tranny cooler and got myself mixed up - will fix up above...

Sorry for going slightly off topic with lame brain ideas - I was going to just spray the IC but try to hit the tranny cooler in the process.

 

+1 to that!! after my clutch and flywheel i think a new tune is nessecary but just wanna get some feed back on w/m

 

got it!

 

booger,

You do not have to have an Fcon/AEM/Motec to do this. You jsut can't use the cheap Snow PErf-type stuff..

Here are the two that can do what i described in a standalone fashion:

Aquamist 2S and FJO's w/i setup with the stanalone computer option.

FJO seems pretty slick, but I just have not seen one at work). It's certainly much more elaborate than Aquamist's setup with respect to programming. It has a fully calibrated solenoid drive, and full 3d maps configurable by a laptop.

You can do the same with Aquamist, but the programming is done in a more arcane fashion. I am going to do Aquamist 2c (whcih will accept a PWM input from the Fcon) from GTM. Aquamist has been shown to work extremely well, by a wide variety of racers/entusiasts. And their stuff is very very reliable. I have not seen any user input on FJO aside from one, hence my choice.

the water meth kit richened up a 15 psi car from about 11.4 to 10.5 on the shot he wanted to run. i really dont see any advantages of it after playing around.


yes it cools the charge, yes you can richen it up BUT it made less hp so i would rather richen it up and turn down the boost some...

i am sure on a motor that could possibly hold 10 psi, adding a 50/50 mix to it and turning it up to 12 psi could have its advantages. i personally wouldnt want my motors lifespan to depend on it...

 

So after you installed the meth you didnt lean it back out to 11.4? and you saw a drop in power?

 

yeah the 50/50 mix took about 30-35 hp away on the 535 hp car, the only thing that i dont know is the amount that he was spraying. i think i would rather not use it and keep stuff simple and effective. the 50/50 mix actually richened it up to 10.6 from 11.4.


we then tried adding nitromethane to it and it didnt really do anything.


i now want to do some fun stuff. i want to inject Gatorade into AJs motor for fun, we might really try it. Maybe some Monster energy drink!!

 

That's the beer talking!!!

Tomorrow he will think.... boy that was stupid idea! Lets put sticky sports drink in there. It will be a fire ant magnet.

we were actually talking about trying some Moonshine!!


we thought about that, but the ants cant get into the piping??

 

JT.... not one of your better ideas! Trying to get a Gatorade sponsorship? Try drinking it!

Yea i know it should richen it up a bit but once it richened up did you guys pull fueling back to 11.4?

 

I have been keeping my eye on the aquamist kit as well... I would like to see if I can run 20psi on 93 octane using straight meth, no water...

I have some supra buddies that are using this and running 700+whp on pump gas...

I think it can be done, but need to do some more research. It is interesting to know that the Aquamist kit will take a PW signal from the Fcon... That may be the way to tune it. I am also wondering it there is a way to tell the Fcon to jump to a submap if the meth does not activate properly (i.e. you run out of it)...

 

Thanks...I'll look into it

 

Jeremy...did you lean the A/F back out to what it was or leaner ? You can actually run leaner because of the cooler intake and add timing back in to make more power than with out it .
Running the SC at 18 to 20 psi , the w/m makes me feel better that the intake temp is much lower .

 

I understand how beneficial this can be with turbo applications where max boost comes on relatively low, but airflow still increases until redline. But how beneficial will this be with superchargers like Vortech? Centrifugal SC's that reach max boost at redline (usually only hitting between 7-10 psi), so max airflow and redline would be at the same point. I believe with the Snow kit, you can vary the spray pressure in increments of boost, so at 2-4-6-8 psi. Because boost changes with airflow almost in parallel, a snow kit would be sufficient I believe. No?

 

I am no tuner here, but it doesn't sound like you were properly tuning for the meth injection. You should have leaned the car back out, ran more timing and been able to make more power at the same boost level -> mainly due to being able to run a more agressive timing map.

Maybe his injection kit was not optimal, but it doesn't seem like you were doing what was needed to take advantage of it.

 

From my research, it will help a lot of superchargers. Their charge temps are fairly high and meth/water injection cools those charges temps.

 

Some have claimed a power gain from water/alcohol but that hasn't been my experience. I have used it for a total of 14 years on two different turbocharged street bikes and have drawn the following conclusions.

1) Water alone does a great job of preventing detonation. I initially used 50/50 water/methanol but found straight water worked just as well without the corrosive side effects.
2) While cooling the combustion process it did not by itself increase HP I believe because the water displaces some air/fuel. It does how ever allow a much higher boost level but you need a bulletproof system if it’s the only thing preventing detonation.

I currently use a AquaMist pump which works well but a warning to anyone considering it for use on a car engine is that my pump is max'd out supporting 350hp. This is why many people are using larger pumps.

 

I was referring to Gurgen's post saying that its better to go with a kit takes into account airflow rate instead of boost pressure.

 

i know we didnt take advantage of the meth, he just wanted to spray it on top of it so the tune wasnt dependent of it.


and i was letting you know what it did, if we would have had more time , we would have leaned it out to see what we could do with it.
