For me to see any reasonable drops in intake temps, I need to put the controller of at least 4 of 10, 10 being max. At that point, he will be running rich, possibly too rich. Spraying little amounts of water/meth wont do much IMO.

Running 100% meth cools the intake tract down more than a water/meth combo.

 

I have the Snow kit and Start spraying at 4psi to redline.My map is tuned for the meth it's a 50/50 mix. This winter going to tune without meth afraid of the lines freezing. All it takes is a air bubble to freeze and Knock will come.

 

Well as with anything...**** happens. Anything can fail at anytime and as gay as it sounds..its the risk you have to take when you make real power. Im sure for what I want the AEM or any of the others will do the job fine..im not looking to make 100 extra hp and sqeeze out every bit of performance I can...im just looking to make it safer.

 

When the Snow kits first come out I had one of the early kits with the old plastic nozzle it worked great when I was procharged but now with the turbo It would blow the nozzle apart when under boost and when it did it sounded like popcorn under my hood because I was tuned for meth and timing was kinda high in certain areas of my map. Since then Snow has replaced the nozzle with a all metal one. No problems now. Next tune going to have muti maps with and without meth plus more.

but if you aren't tuned for it, it could be more trouble than it's worth.

 

You should be good.. Meth don't freeze, this is why Winter Windshield Washer mix contain more meth than the summer mix. If you are running straight water then you will be in danger of freezing it. Go buy a -35F Windshield Washer and put that in your freezer for 10 days. Let me know if it freeze, -35F only contain about 35%-40% meth.
