you want to run between 20-25% of how much fuel you are using. so if you are running 630's then have both nozzle psi ratings add up to roughly 500-630cc. mix and match the 2 either way you want. i would run the larger one at the TB though. maybe im wrong in my theory, so if so someone please correct me. as i only run one nozzle currently.
i run strait blue -20* washer fluid. it's 60/40iirc. could be 70/30 though.. the more water, the more cooling, the more meth, the higher octane. which a 50/50 mix of water and meth is said to bring 93oct to 104ish. denatured alcohol has not really had great results from the B6 guys. i would just stick to washer fluid. or go get a drum of meth and mix in some distilled water with it to your liking. make sure you log log log if you change any timing settings!
yes, hook it up to the MAF. it's very easy(1 wire) and it's the only way you will be able to control the onset of when the mixture sprays.
and i've heard that it can damage the TB. but only after a very long time-READ 30,000ish miles. and TB's are cheap at the junk yard. so i wouldn't worry about it. meth is worth it!
FWIW, i run an devilsown kit w/ no failsafes. but i also dont run the meth currently for the sole purpose to run race gas timing on pump gas+meth. just bumped up the timing a slight bit and enjoy my very very low IAT's.
have fun and good luck buddy!
TO ALL: You don't just abitrarily select a nozzle size, there is a equation that is based on injector size, boost and Fuel Pressure. Call SCOTT at USRT if you need to know your nozzle size(s) or use their website where the information is hosted.
Sean you don't want to run the larger injector at the TB or just after it's the opposite. You run the larger first in line and then the smaller 2nd, my setup is the 375 ml/min first nozzle and 60ml/min at the TB plate. You also don't want to run a MAF based kit on a non-MAF running car, just won't work. The MAP controlers are more accurate and offer much much more control of onset, since it is boost derived and not airflow. You also will use/waste less h20/meth.
You need one anti-siphon as you can see in my pictures below for a dual nozzle or a trunk mounted tank, but only 1 if running both. The new safe-injection by Snow may be very different than the previous version, but the last version couldn't catch and correct as fast as ME-7 and was proven as mentioned by Nate (gent behind Snow who has left and now has the same kit with a new name). Nate also had a B5 A4 1.8T and that is how I know this.
Tuning wise you either tune for power or you just use the h20/meth for lower IAT's and slight octane increase to allow more timing. I personally have very mixed feelings after running the kit for 10k and when lapping sessions are going on will only run distilled h20.
I run a dual nozzle setup. I run the Integrated TB Plate and the 1/4 npt fitting to screw the 1st nozzle in at the discharge piping at the core. I run 75% Distilled and 25% VP M3 as my mix.
