USRT Group Buy: Snow Performance water/alky injection

[Scott@USRT]

Why did this chap go with propane injection (which is more typically done with turbo diesels) rather than water/alcohol?

[nutbox11]

im not really sure. 950 to the wheels, i didnt really ask why. ill try to find out.

[Derelict Dub]

Does anyone have a general install for this set-up on a supercharged motor?

[adcockman]

I don't know. But it would be nice to reference another install before i do mine.

i lvoe my wi kit. i have a cooling mist pump and snow var. controller. don't really have instructions i could type up one tho if anyone needs it, here are some pics. btw my intake temps were 74 degrees at 20psi with no timing pull on apr93oct and 93 in the tank.

everything is in loom now and much cleaner.

edit* mine is a water/meth kit which is what you showed in your pics, i tryed running alky and my intake temps went waaaay up.

Has my new kit shipped? You expected it to ship last Wed. or Thurs.

Thanks!

[adcockman]

My new kit has arrived! Let the fun begin!

Thx

You ran 100% alcohol and your intake temperatures climbed? That's an interesting result and probably means that your previous water/alky mix was evaporating fully in the intake tract. Best detonation control comes with a greater percentage of water and with some of that entering the combustion chamber in liquid form. A greater proportion of alcohol generally cools faster, though, and is often less sensitive to tune.

If your intake temps are higher than you'd like, I'd run a greater proportion of water which changes phase more slowly but removes more heat in the process. Moving the spray nozzle farther away from the head (to provide more time for evaporation) will cool more, too.

cool man thanks... i'm running the water/meth now, but if i try alky again then i'll keep that in mind.

ok....i've been interested in this setup for a while now, I was actually part of the GB with dragonfli_x over in the VF forum that didn't seem to have enough 'G' at the time.

I'm running VF's Stg 1 6 psi non-IC setup for a VR6, and i commute 100 miles a day. I'm noticing that when the outside temps begin rising over 70 F or so, it's very obvious that it doesn't accelerate as hard as if it were like 50 F or colder.

Would WAI give me that 'colder' feeling again?

[Scott@USRT]

You've got a non-intercooled VR6 with 6psi boost, eh? Yes, you're going to see substantial gains with the WAI. With it, your engine may be significantly more responsive at the current boost level. What's more, you'll be able to safely increase the boost pressure from where you are right now without fear of detonating. Yes, this parcticular application is a no-brainer.

Wow, is WAI finally catching on around here? It sure seems like it.

Its about time, always knew the truth about it, and always was into it! But about time for others

[dash cunning]

yea i'm glad people are finally seeing the light and what you can do with these systems.

[TnT2theMax]

Scott are you going to be running another goroup buy anytime soon? Or is there any specials?

[EternalXresT]

(3:30 AM 4-30-2006) EternalXresT: any specials going on with water/alky kits????? would like stage two. do you think i should wait for stage 3?

(10:15 AM 4-30-2006) Scott@USRT: The controller upgrade brings a Stage 1 kit up to Stage 2 spec. the difference *is* the controller which is inluded in S2. As for specials, there actually is one going on until May 15th for the S2s at $359 + $15 shipping. The Stage 3 will go on sale in June (maybe for an intro discount off the regular $499). So, you may want to act now to get the most bang for the buck or wait and get a more tunable system. Consider your priorities and make a decision thusly.

[TnT2theMax]

Thanks

[EternalXresT]

No Prob.

yay! this will show stupid tx and their stupid heat whats up.

[Scott@USRT]

Thanks for the orders guys. This promo deal will end May 15th, so come one/come all while the goods are still at "steal me" prices.

[crzygreek]

damn i just missed it

[adcockman]

Scott, I only received the two larger nozzles in my kit. Could I get the 225? I think the 375 may be too large. I have the pump turned down (2 full turns) and also the max voltage turned up past 5 volts. No bogging, but I'm going through a crap load of fluid. I would also think running a higher psi on a smaller nozzle would be better too.

I have the system coming on around 2.9 volts. It doesn't seem to be using as much fluid. But is this too high?

What are your thoughts?

[adcockman]

Guys... I've recently got my kit up and running. I haven't made it to the dyno yet. However, I've been doing some test runs. What can I say... It works. I'm running 3 degrees more timing and it keeps the intake manifold very cool even while beating on it. I suspect I'll be able to run more timing. But I would rather wait for the dyno...

FYI I'm running the 375 jet with the pump turned down to roughly 100-110 PSI.

Scott, what would be the advantage of running the full pressure? Increased control.

[adcockman]

This was the last tune on the dyno today.

This is a comparison of the dyno pull in Jan. vs an earlier pull from today. Note the power and tq increase across the full power band. Also this is pretty incredible considering it was 50 degrees in Jan vs the 100 degrees of today.

Just thought I would share. This was done with the small w/m nozzle.

[beachball6]

what was your 1st dyno run on? 93?

did you re-tune the car at all? doesnt look like it

[Alaska]

just my luck to find this afte the 15th!

as of now being June what have the prices changed to?
I'm running stage3 VF
11psi w/FMIC
Thanks

[adcockman]

Yes... the car was re-tuned.

1. timming
2. proper nozzle size
3. pump pressure
4. just a little love
5. Proper in and out point on the Snow/Meth Controller

I put down 270 or so back in Jan. with minor advance timing. I don't have the print out of where we started yesterday. The final tune had more timming advance than when I went in.

3 inch exhaust will be the next test.

In Jan my base run on 93 was 270 on the same dyno. But the timming was bumped a little. My goal was to get the same number sand not need to run race gas all the time. Goal achieved.

[beachball6]

im sorry, i didnt notice the dynos were the same day. oops. it was layed out as if they were different.

cool so you got 20hp w/o any boost modification just timing. ohhh i cant wait lol. ust waiting on a smaller jet.

[adcockman]

Modified by adcockman at 11:05 AM 6-4-2006

[adcockman]

no prob. The fact is I put more hp and tq down with water/meth than I did with Race/93. Obviously, I wasn't able to run race gas everday since Jan. Now this setup will be much more cost effective after the initial investment.

Good stuff!

[Alaska]

bump for interest and dammit cuz I only get 90octane in Alaska
so my performance gains would be less then that-
Then again my ECU is only programed for 93

*currently I run torrco fuel additive to boost my octane-

[Mad Caddies]

Would this kit be logical for someone with say...APR 93, DV, Exhaust, downpipe, and other small stuff like that?

[adcockman]

of course!

[VWturbo2Ltr]

water injection does not care what your current setup is.......... from stock to the craziest of setups you WILL make power........ period.

in my opinion you get even more bang for you buck with water injection vs your standard chip program
