Methanol Injection

[dannboss]

Called and spoke with Snow Performance earlier and received quite a bit of information to think about. I have seen a few people on this forum that have the Stage 2 kit, and am wondering what their thoughts are. From what I can tell, and what I have found through search, is that this will lower the intake temperature, allow for advanced timing, and essentially run what looks to the car as 116 octane (approx). The kit wasn't expensive and the claim was about a 25% increase on gas N/A vehicles. I will take that with a grain of salt, but eve at a 12.5 % increase you are looking at about 50hp crank.

Discuss.

I've been running stage 2 for a while so have some feedback.

Kit is fairly straightfoward to install (reservoir is in trunk)
Go with medium to small nozzle size otherwise you will get through 2 gallons in 10 mins
I have no idea whether it resulted in any performance improvements. I run it as a bit of added insurance on the track mostly. Rest of the time it runs dry.

The tubing supplied is inferior and will crack/melt easily so make sure you sleeve it well for protection or get better tubing.
Getting the controller setup takes quite a bit of experimentation. You either go from dumping gallons per second to running without meth. Need a steady hand. I have it setup to kick in at 5.5 psi roughly (I'm running a maggie).

Having to constantly go down to the hardware store is kind of annoying.

It is true that you can advance timing to your hearts content but that doesn't necessarily translate to any realistic gains past a certain points and you're running the danger of fireworks if you run dry, your tube cracks or the pump fails so my advice is to never ever tune specifically for high supply of meth.

I run a 50/50 water/methyl mix.

My advice:

Buy the biggest reservoir they have.
Get the low level meter (if not supplied)
Make sure your tuner doesn't go crazy with the timing

No way you'll see 50 at the crank. You don't get power from Meth (or more octain). It's what you can do with the Meth.
As far as 116 octain, keep in mind it all depends on how much your spraying, and your mix.

You will get power from meth with advancement in timing. You will also notice a BIG difference on supercharged/turbo cars in the hot weather.
Cooler operating temps=more hp. I run a 75/25 mix in a procharged mustang. Don't use washer fluid it will kill your hp even with the best tuning in the world, it's garbage. Methanol injection has to be set up properly (jet size, tuning, meth mixture) otherwise it can actually hurt your performance. You shouldn't be going through 2 gallons in 10 minutes either. If it's set up properly a quart-2 quarts should last you a month unless you are beating on the car constantly.

to the op..

meth and nos is an oxy-moron...what's that point?
meth and FI make gains do to cooling the hotter iat's FI produces.
nos is the best chemical intercooler bar none.
if added octane is what you're after, i suggest another avenue.
IE: an in-tank octane additive or unleaded racing fuel

as far as the snow* kit... it's over priced junk.

it's better to use your own WW reservoir as it over a gal and a qt
at full capacity,... then piece a kit together from this site.

for any more info, ask the know-it-alls on this site, as they are sure to know your car, and needs better than you do.

i forgot to mention the reason for our own ww reservoir is that
it has it's own built in low level on the nav screen. pimp i know.

also you can t-off the headlight washers at the base of our tank as i did, and it will also purge the system. again..pimp i know.
also, you must relocate the iat sensor after the meth and before the tb as to get a correct reading for the computer to read proper values as to not retard timing (due to hi iat temps) when the meth is activated. otherwise it's all wasted time and money.
good luck, and let me know if you need any help, as i will not only give you the help you want, but also the help you need.

Snow is expensive, there are many other options. I used to run WI on supercharged Mustangs and Miatas. Great for boosted applications, total waste of time on a naturally aspirated application. You want improved octane rating, get some Amsoil or Torco octane boosters. Both are reasonably priced and very effective.

I called and spoke with the guys at Nitrous Outlet regarding a methanol/n2o combination and they said that the n2o is essentially providing the same level of "coolant" to the cylinders that methanol would. Running both would probably not make that much of a difference.

On supercharged and turbo cars methanol makes a huge difference, possibly upward of 100hp. The only issue you run into is that the methanol can cause issues with the maggie, so ideally a turbo setup with methanol is what you're looking for.

Those of you who know about the potential of cummins turbo diesel applications would still be amazed at what methanol does to those trucks. Somewhere north of 30psi on the turbo and methanol injection with the proper tune is hitting 1000 ft lb/tq.

So, to the one guy I know of running a twin turbo V, methanol injection.

I will pass.

They work great with a centrifugal blower set up too. Good info you got there

Ooh, how does one relocate the iat sensor?

Is it part of the MAF housing? If it is, presumably I need a breakout harness for the sensor. Anyone know of one?

Let me guess, you paid to get your Maggie installed
Your IAT sensor is re-located. It's on the rear of the Maggie, pass side. And yes, it was part of the MAF.

sure hope u guys are wrong about SNOW PERF being junk...I just purchased their stage 3 kit... pretty pricey...i am going to try to hook it up this week...
it is going on my 483rwhp C5. My motor was just detunned rom 498rwhp to run on the 93 ethanol crap...plus i went from a stage 3 CARTEK cam to their stage 4.....can't stand the lost hp.... here i have the parts but not the right octane or timing to get the performance out of that stage4 lopeing cam....
i am getting it tunned WITH the meth kit probably with a 50-50% setup on Sat. Nov.14th.... and I'll come back and let u'all know what hp and tq performance gains if any i getthe tunner Jeremy Formato is supposed to be the best on the east coast for the LS motors....and i will just see what he can safely do.... ps octane boosters suck. there a waste of money...bogus claims....only way to go, from what i have learned is good old quality race gas or meth-alky inj...This kit i bought is meant for a NA motor.
Lookin for 515-520rwhp. That should have me running 10.30's to 10:40's...Anyway I'll report back early next week....seeyaGREG O.

The Snow kit isn't "junk", it's just there are better, less expensive, kits out there. I've used WI on supercharged Mustangs and Miatas, and I found the best controller was from Devil's Own. I made my own water tanks from 2 coolant overflow tanks, then bought the Shurflo pump from McMaster Carr. I did buy a few odds and ends from Snow. I tried their controller before, but the Devil's Own controller was a better design and cheaper.

The only reason you should be tuning with the Meth is if you know it is always going to be there, or you have a knock sensor that can quickly retard timing. I used WI/water injection as a safety feature on my cars while open track racing, not for more power. VP Racing had the best price on a 5 gallon can of Meth when I was using it.

Things may have changed a bit since I was into WI.

Well, it looks like i am going through with this mod...

Presently i am changin the heatshieidin on my LPE CAI from Normal to the Gold foil from DEI. Added heat protection.

I also am going with Cooling Mist. I heard that Snow went to court for Patent infridgemt and lost. Cooling Mist hold the original Patent and design.

Presently to keep weight down i will be hookin up the pump to my water resevior, puttin in a float switch. I am also getting the Smart Controller as well as the Vari Cool Controller. I will be tappin into the IAT, RPM, MAP and MAF. I will be relocating the IAT from the MAF to the EGR location on my FAST intake manifold for better Temp reading. The thought is when the IAT raises here the PCM pulls timing, but if my IAT lowers it adds timin...I will Have the Controller read the temp and if it is above 35c its starts the activation, it will then wait for the MAP to be above 55KPA and the MAF to be Above xxxx and finally Rpm to be above 3200rpm

This way i control the amount of flow needed as well as keep the sweet spot sweet. I will probably start it off at 5% at low and have it climb up to about 60% when i am done. I would need a 400cc Jet now, and a 550cc Jet later...

I hear also it cleans up all that carbon on your valves, keepin the seal clean, not to mention cool your EGT tremendiously.

As an added percaution, i upgraded the Fuel rail from LS1/6 to the LS2, and am gonna chuck the Ford injectors for Bosche 42lb. better spray pattern nd come on, its Bosche Ze Germans know Zeir Stuff...

Cooling Mist makes a nice kit, pricey, but nice.
