Pot of hp stew that'* a good one.

I bypassed all the electronics and wired direct to the pump for testing only.

It is based on MAF not boost.....somewhat related....read up on the SnowPerformance.net site.
"Snow Performance has developed a new Stage-2 Boost Cooler™ water/methanol injection system for ’96 + GM mass air flow equipped vehicles that uses a new Digital Variable Controller that varies the quantity injected with the engines mass air flow. Because the correct amount is injected at all RPM/engine loads, power and drivability is much improved over the typical on-off systems. The Variable Controller features adjustments for onset mass air flow level and full quantity mass air flow level so the injection curve can be maximized for each application and can be mounted under hood or on the dash for adjustments while driving. The Digital Controller reads the frequency output from the GM MAF sensor to the PCM and varies the injection quantity accordingly.

Other Stage-2 features include a 150psi pump and specially designed two-chamber nozzles for even better cooling/atomization."


I redrilled using a 23/64" bit and it was just enough. Any bigger and it would have been too much.
It'* perfect now. The spray pattern is much improved with no dripping. Very good advice Bill, thanks.

Time to button it up and get rid of the Pot.
Now back to wiring....

i would really like to see the results after you are done ... there are two camps on this injection stuff - those that say it works and those that don't.

Good luck!

Of the two camps, those that don't believe in it fall into two categories:

1. Those that haven't tried it
2. Those that tried and couldn't figure it out.

I've been running it for 3 years. It works. Period. The US military used it in WW2 for that reason. Why do you think our supercharged bombers could operate higher than the german fighters?

Glad it'* working out, Paul. You'll need it from 30-60mph against the Zilla.

I agree with Bill. Tuning will be key to obtaining results. If you use this system and don't do anything else, you won't see much gain......but add some timing and boost and look out.

Bill, from the results of your latest efforts with Zilla, I'm gonna need it from 0 - 155.

i'm not saying it doesn't work - i just want to see the results ... Proof is in the Pudding.

Track times before and after, Dyno charts, something showing that the injection worked without other mods. yes, i know the idea is to get rid of KR and still drop a pulley size or two. What i mean is no other mods - like new trans, gen v upgrade, cam, etc. Are you tracking with me?

i am interested in trying it, once someone can show me that it works (and how they made it work - i hate reinventing the wheel, when i can copy it). i almost bought a kit last year, then i found a really good deal on the intercooler(which i still need to install - :( ). i would love to install one of these injection kits instead of taking the next (EXPENSIVE) step to better heads.

Good luck and let us (me) know how it goes.

I think that W/I will work well but tuning is the key. From what Bill has been saying, tuning is next to nothing...

You will find out the results after this summers Meet. I will have better times than you. I will have no other mods since last summer. :P
Seeing that your goal is to beat us this summer, do you really think we're going to do dyno charts for you. Are you tracking with me?
Just get your intercooler installed and you might stand a chance.

are you putting in a cam or sticking with the 1.9s?

do you think you will be that much faster with 1.9s and the injection?

I ran last year with the 1.9'* and have no plans for a cam this year.....PDad is I believe.
I also ran a 3.1" pulley last year.
Your 60' with street tires is impressive. It must have been the track prep. Were you using a 3.4"? What mph did you trap at?
