I've used the SMC kit and currently using Snow Performance. Both worked equally well. Methanol is pretty corrosive, but I ran it for a while without problems. Ethanol (if you can find it) or denatured alcohol (what I currently run) is much less corrosive and hasn't caused any issues.

Which kit is made to run using the factory washer tank?

 

The SMC kit offers a new washer tank with the pump inside. However, I am using my stock tank with the Snow kit also. He gives you the fittings to do that in the kit, with one simple hole to drill and snap-lock fittings. Good thing is it can still be used to clean the windshield as the washer fluid is alcohol and water. With the SMC kit you don't get the stock washer pump anymore.

Where in the induction setup are you injecting the mix - I've seen more than a couple of recommendation in the past - just starting to look more seriously now.

In the inlet boot/elbow before the throttle body.

Think we could use the extra inlet port on the JLP sheet metal intake?

 

Don't see why not other than possibly having to install a one-way valve to prevent siphoning; that port has vacuum.

Crash; you do mean richer by .5 to 1.0 for the 50/50 correct?


Jody; what have you seen with it compared to tuning? Curious because I am about to have the basic same setup as you, and am getting more interested in this over race gas, xylene, or torco.

 

I've seen a full point richer when running straight alcohol, but I've never seen it go leaner with a water/alcohol mix. I will say that water is a better heat absorber than alcohol, and I've run straight water in my ProCharged cars with good results. But on the Lightning running water has not worked as well for me. You can be into boost just climbing a hill or entering the freeway enough to start the injection system and with the water my truck would stutter under those conditions. I start the alky at about 10 psi but even that is easily reached at part throttle with a roots blower. So I run straight denatured alcohol now so at least it burns and the truck won't stutter under higher load, lower throttle positions. Plus there's even more of an octane boost that way.

What's it cost to fill the tank with denatured alcohol and how long does it last?

 

? on the MAF triggered kit. Is it fairly adjustable? And is it progressive in any way? Like comes on at x.xx MAF then increase as MAF voltage increases?

 

We sell the Snow kits and are very happy with them. Matt Snow was at our facility last month and we did an installation and tune on a Cobra for an article in 5.0 Magazine. We used a StageII MAF kit, which is what we sell exclusively.

Racing methanol is fairly corrosive, but we have not seen alot of problems with it yet. Denatured alcohol, although more expensive, is less corrosive but you have to mix more of it and less water to get similar results. Methanol is about $5.25 a gallon and can be purchased from any racing fuel company such as VP. It is generally used in a 50/50 mix. Denatured alcohol is about $7.00-8.00 at Home Depot or Ace and is generally used in a 75/25 mix.

The resevoir in the Snow kit is fairly small but will still last about a week under normal driving conditions. Remember that, although the system is armed all the time, the alky "shot" is actived only when you reach a certain maf voltage. The voltage is set during tuning and is usually set at half to two thirds throttle. Just like a nitrous setup, but a lot less expensive to use.

 

hmmmmm....

 

I logged several runs (blasts) leaving the track that night. Each time, at WOT the Predator was glued to 21 degrees. I am sure where the timing was.

Timing has very little effect on A/F. I don't believe that three degrees threw my A/F ratios so far out of whack that I didn't pick up any ET because of that....

 

Anyone try the Snow Performance "Nitro" additive claiming 50 additional HP?
