I'm on Meth

[yagey]

but in the meantime, this is the setup on my 2.7 A6 -

Interested why you have a sprayer in each cylinder like that? I'm def. no expert, but I thought the idea was to spray a mist far enough away to allow the fluid to absorb heat and turn into mist before reaching the chamber? In my 300z I basically put large sprayers just after the intercoolers.
Also, any chance you are in CA and have to get visually smog inspected? I like your stealthy install

There's a few different ways that water/meth helps with knock. One is to cool down the intake charge, in which case you want the nozzles far enough from the combustion chambers that the water has time to fully evaporate and cool the air.

Another way is by slowing down the flame-front, essentially raising the octane rating of your fuel. For this, you want the water droplets still fully in liquid form.

Wow! Like the stealth install, and welcome!
Been busy with work gals and guys, not much posting lately(@ work right now). Can someone chime in and let me know exactly how the nozzle jets are installed in the Y pipe? I mean, anything special for tapping? Should I just install jets just after the Wagners?(sorry for the TJ)

[4everRS]

IMO you should mount them close to the throttle body. This will allow you to access them in the future if you want to change the nozzle size. Use a new tap when doing it. Go slow and use lube. That aluminum sticks to the tap so bad.

How they mount depends somewhat on the kit you use. Generally it's just tap a hole and thread in the nozzle. Also, some of the company's offer mounting options for soft pipes (if you wanted to mount them in a silicone hose).

A good option is about 8-12" before the IAT sensor, so the ecu sees the cooler air charge and can give you the most benefit.

[4everRS]

everything is such a pita to get to input engine compartment, it makes our sensible options very limited. A mount in the hose would be great right before the Y pipe, but then you need to hope to never change it.

Good thing is with our cars that the IAT sensor is inside the intake manifold by the drivers side fuel rail (according to pat), being about 6-8 inches away from the TB, so it should be able to make a timing difference. BTW, anyone know off hand what log block IAT's are?

[MaxRS6]

Hmmm- I may need to consider this while they have the engine out...However; I don't know if I need to throw another item into the mix considering the march I've been on. However; I need to give this serious thought seeing that I'm located very close to the devil's gate. It was 102 here yesterday and I could barely manage to get in and out of the golf cart while chasing the white ball..LOL

[Pit Viper]

If nothing else, you could have fittings installed for the jets while the engine is out, and just block them off until such time as you decide to install it.
I live in Phoenix, and I'd never run a turbo car here without it.

^ Thanks for the input Viper

Just logged IAT's over lunch. Results are no water/meth vs. (you guessed it) water/meth injection. Measured in degrees C. Ambient temp is 30 C

Pit Viper, where can I get that cool trick gauge pod?

[snoopra]

OK, will do.

Find a good fiberglasser.

Randy the meth injection really works, especially when u step on it, I have not dyno'ed since, but I have been running this system for 4 months....well worth it.

[ttboost]

have had it on my 996 turbo for a couple years now...HUGE inprovement on that car...

[peiserg]

anyone interested.. i've got the meth system i took out of my NSX... it's the Alkycontrol 3d progressive setup. includes everything, including newly rebuilt (by alkycontrol) pump. PM me here i guess.
