I have just recently set up our shop with Snow Performance as a stocking dealer for their product. I am well aware of what the performance gains are for boosted applications, and will be doing quite a bit of testing of such. I have talked with Matt (Snow Perf.) at lenght about the capabilites of his systems relative to nitrous. And it is impressive. My question is has anyone on here tried it yet? Cliff notes of our talks are as follows: you can run stock plugs, stock timing, and still get ~30% more power out of a given shot size w/ 0 detonation. Almost too good to be true. Opinions and experiances welcome.

 

I can not speak out of personal experience, but a couple cars the have been worked on by the local shop I go to run these snow performance kits. One car, I believe a 2001 Mustang Cobra picked up two tenths in the 1/8 naturally aspirated with the kit. The N/A application would benefit because you could run pump gas and be able to jack the timing up a bit without having to worry about detonation.

I don't think the Water/Alky injection significantly increases horsepower on its own. The fact that you can run 30 degrees of timing and lean out the A/F is what makes all the difference when running boost or nitrous. I guess it could mean a 30% difference. A 100 shot at 30 degrees and 13:1 A/F would be a significant (OVERALL) horsepower increase over a 100 shot at 26 degrees and 12:1 A/F. Basically you can keep your agressive N/A tune and be able to run nitrous on top of it.

Water/Alky is cheap too. Its basically window washer fluid. They were able to get 5 passes out of the quart size tank (I believe it is quart, correct me if i'm wrong).

If anything it can be cheap insurance when running nitrous on a conservative tune. If your fuel pump takes a dump, or your fuel solenoid decides to quit on you halfway through a run, those few seconds on the water/alky can mean the difference between a burnt spark plug and a burnt piston.

 

You mirrored everything i would have said if i went into more detail. You are absolutly right, you would need a retune to take advantage of the meth inj. And we both think alike, at the very least its (very) cheap insurance against detonation, and you can run an agressive stock tune as well. I see no down side. Anybody else?

 

i've always wondered about running a alky/nos wet kit. i think it would work better than people think and i'll probably do it when i build my nos noszle kit. i say go for it would be great R&D and most likely open new doors to the juice kits out there

 

I'll be trying it in the next month. My ls1 nitrous plans are on hold for a little while longer while I get the bugs worked out my stang. But soon..

 

a friend of mine told me(hearsay) that spraying nitrous and alcohol in the same place will tend to freeze things like intake valves and such.

 

hows that possible?

 

I sure hope it gets that cold! But somehow I doubt it

 

I went to SNOW's website and thats an interesting kit they have there. Especially with the progressive window switch. It would be great to be able to run more timing and be able to lean my car out. My car runs like **** N/A. Im only running 22 degree's of timing and 11 to 1 A/F

 

I am very interested in this. Let me know how it turns out.

 

Well i bough our company in with Snow last week, to the tune of six kits. These are all destine for blower cars, the intended application, ranging from a 330 whp Nissan Maxima to a Novi 2000/AEM EMS equipped SRT-10 Viper (first one of those kits shipped to our shop, just arrived today) that will do somewhere north of 700 rwhp. My car will be the first to try it with the nitrous, Im thinking next month. I have to get the NX kit on the damn car first (to many customer cars, cant work on my own ) and i will be sure to make an extensive post on the results when i get it done. The plan is for a 150 shot jetting, single nozzle Snow Kit (STG I, i dont need boost referance and linear progression obviously) NGK TR-6s and then take it as far as i can on the dyno while maintaining a safe AF and no KR. If i get back to 29 deg of spark and all is well, i will stop there and call it a day. Hoping for 165-170 rwhp out of a "150" shot. I am also interested to see how the kit affects overall AF, as i have been told it tends to richen the mixture .3-.4. All this is on a stock fuel system (02 car) so it will be a good base to measure off of. I will let you guys know.

BigPlan, the only thing i can think is that the meth is a 50/50 water/meth mix, and the N2O freezing the water, but somehow this doesnt seem to be an issue according to what i have been told. I talked to Matt (great guy by the way) about this at length the other day. He said they have several cars spraying with the meth and it works wonders. We shall see.

 

Are you talking about supplemental methanol injection (like used on turbo/sc cars), on top of a normal dry or wet nitrous kit?

 

Yes. Wet kit in this case. Why you ask?

 

why would you run water with the methanol? the nitrous and the meth itself should cool you down far below ambient and you wont have any unburnable substances(water) in the cylinder. the water seems kind of useless to me as it thought the meth was for fuel enrichment/octane with the extra cooling as a nice little boon.

 

> Yes. Wet kit in this case. Why you ask?

The primary benefit of methanol over gasoline is running rich with methanol doesnt hurt power as much as running rich with gasoline. Another benefit is that methanol is higher octane than pump gas (101).

If not for methanol's advantages over gasoline, then why wouldnt you just run it rich by using a larger jet on the wet side? Seems like that would be simplier. Since methanol does have benefits over gas, it seems the most benefit would be gained by replacing as much gasoline as possible with methanol.

Rather than inject gasoline in the wet side of the kit and supplemental methanol on top of it, why not just run methanol in the wet side of the kit? That's what I'm planning to do.

Since half the engine's fuel would be from methanol, you could run it nice and fat so it's safe, without losing much horsepower like you would with gas.

wuteva u run im willin 2 bet my 5sec porsche wood eat it up lyke puppy chow

 

First, where the hell did that last post come from?

Slart- Ok i see what your saying. That seems like it would be an option at some point. At the outset i will still be using the gasoline as the supplemental, once i get a little more aquaintaed with methanol i might go over to using it in place of any extra gasoline on the fuel side. Just sitting here thinking about it, I just might give Matt (owner of Snow) a call later on (hes on Mountain time, Eastern here) and see what he thinks about it.

 

Anyone have any more input on this?

 

Well, we've got 3 of the kits we ordered on vehicles, 1 diesel truck, a H/C/P1SC Z06 and a blown Maxima. They seem to work very well, and we will be putting the Max on the dyno Friday and tuning to see what good the meth really did. The Z06 will get retuned the following Friday. As for the meth/nitrous, everyone is just haning out waiting on me to get it on my car and try it. Should be soon.

 

what about a N/A car? methanol itself is almost a poweradder for FI cars but im more interested in how it does on a N/A car
