did i do something wrong or is that normal?

and ive noticed it really use's a lot of the meth.. i did about 6 WOT logs and the tank dropped about an inch. is that normal?
what do you mean by it got richer ? Are talking about tuning it on a dyno ? Essentially (maybe Dan can comment on this ), you should leave the pump pressure alone and stick with adjusting the nozzle size until you get to the point where the car begins to misfire. Once she misfires, go back down to the smaller nozzle size. Then you can adjust the pump if it still make sense.


how long time was are your WOT runs ?


Dan, am I wrong here at all ?

How rich are we talking, like is it dropping from 12 to 10 or is it dropping from 12 to 9...

yea you got it, with an evo on stock based turbo the 375 ml with pump left at stock settings is usually more than enough...I have tuned several evos with that setting and all have came out great...

on 93 my a/f is around 11.3... when i hooked it up it was at 10.8. so i cranked it up a little more and it went down to 10.2 and wont go any richer than that.. so i have the pump set to force the car to run a 10.2 a/f

cheers!

your a/f mixture at 10:2 is leaving some power on the table. I would retune the car and put the pump back at where it was originally. The ideal a/f on pump gas at wot is 11:5:1 approximately. You can have a second program with h20 to run leaner if you prefer or keep the same program and run more boost.

Couple questions for Snow:

1. How do the Snow kits control alky flow? Does the pump pressure change?

2. How is the new pump on the website better than the old one?

new pump:

Thanks!

1 4 ways, boost pressure switch, or maf progressively, boost progressively or 2d with maf and boost progressively

2 its been out for a little while now and its basically got a couple new features that make it even better than before, like the built in check valve...

Does the pressure in the system go up and down with the amount of flow commanded by the the controller?

Dan, you could have told me about the "Solenoid Upgrade"
Shut off solenoid is used when mounting the injection nozzle lower than the reservoir or the reservoir is rear-mounted to prevent gravity flowing. It is also used to prevent siphoning when the injection nozzle is mounted after the throttle body or carburetor and is exposed to vacuum.

this is what I need!!!! hook me up
Part# 40060
...this replaces the unit in the pump right?

to those using the factory washer tanks. are you leaving the wiper motors/tubes hooked up or leaving all that uninstalled and just using the tank for the meth kit?

I plan on using just washer fluid at this point.
