what nozzles is everyone running?
what PSI do you have it come on at?
what % meth/water?
2 stage? 1 stage?
do you really need the solenoid valve?

 

I’m running a 625 and a 375. They come on at 20psi off a hobbs switch. I keep a 50/50 mix in it.

 

I have 2 - 625 nozzles on a Stage II system. Initiate injection at 18 psi...ramps up to full at 40 psi. I run washer fluid for daily driving but only turn on H2O/Meth injection when heavy or in the mountains. I mix 50/50 with racing Methanol for drag racing or playing hard on the street.

I'm running a .625 and .375 nozzle and run windshield washer fluid. I'm just running the standard 150psi pump from Snow. It's a stage 2 kit and it comes on around 20-22 and is full bore around 35 or so.

 

anyone else?

 

I run Snow's competition, CoolerMist Varicool system.

Two 18gph @ 150psig spraying a 50/50 blend. Starts at 30% @ 15psig boost and ramps up to 100% @ 35psig boost.

You only need a solenoid valve if your supply tank is higher than your nozzles. In that setting, without a valve, you potentially risk gravity flowing the W/M into the engine while off (See Hydrolock).




BTW, methanol and "Racing" methanol are the exact same thing.

 

2 - 625 nozzles, pump pressure maxed, 50/50 mix, comes on at 15psi, full at about 25psi. Only use it for drag racing and some sled pulls.

 

Respectfully disagree. Not all methanol on the market is pure.... but yes, if you stay with methanol designed for automotive use, it's all very good. It's ACS grade and at least 99.9% pure Methanol

Run Snow Stage 2 with 2 .625 nozzles comes on at 15lbs and full at 30lbs

 

Anybody happen to know the orfice size in your 625 nozzles?
Thanks, Tim.

 

with the snow kit, does the controller make the pump put out more on the 2nd stage, or does a 2nd solenoid open?

 

Not really a two stage, in my mind. More like a variable controller.
Way it was explained to me the pump gradually ramps up to full output...based on your two settings (start & full on). Pump speed run by controller which measures boost output and electronically reacts to the two dialed in boost settings.

Correct in both the Snow and CoolerMist.

If I'm not mistaken, the Stage 3 kits allow the boost and EGT's to cypher when and how steep a ramp to run as well as have a fancy user display.

 

wish I could help but my controller fried on my stage 3. All I can say is dont splice the wires from the egt guage on the controller to an edge box pyro probe. Snow performance told me they were having problems with it frying some kind of micro chip. They were realy good about it and told me to send it in but I'm in iraq and the truck is stuck in the good old USA.

 

how does it control the pump? just by varying the voltage to it?
