I think we have all seen and read about Snow Perfomances water/meth injection for years. Has anyone installed this system, N/A and supercharged? Is it simply a bolt on kit, or do you have to retune for it? Im kinda under the impression you have to adjust your timing, but dont know for sure.

Timing can say the same on these kits. It does richen up the mixture (AFR). The best gain from meth is the IAT's say lower which let's the PCM advance full timing vs the IAT's getting hot and the PCM cutting timing. I have snow meth kit's in stock for Maf based car's.

Just got mine back yesterday (from Lethal Performance) and saw a 45whp and 20wtq improvement on a non-intercooled KB. water/meth works well. Intercooled cars should see MAJOR improvements with the kit and a tune.

Could you pm me a price to install one on a 98 GT. Ill prolly wait till I build my motor next month, since im pretty close to max hp on the stock motor.

Do you run yours full time? Or do you use it messing around on the street or strip? Does it require a separate tune, like a multi-stage chip?

For the best results tuning is required.

No reason to pm you. Here is the info you require.

American racing headers for 4V in stock. Also snow meth kits!

No it's on full time and totally driveable. There is NO irregularity with cruising vs. WOT. They ran it of the MAF signal and the tune is dead on balls. completely smoothed out my power band + the added hp and tq.

Shawn told Danny we'll be relocating the IAT sensor to below the blower for the most accurate reading. No worries, because that's the ultimate solution. I'm very happy

Your car has alot of time spent on it. While it is a nice setup it needed alot of attention. Takes alot of time on some cars and others it doesnt. Glad your happy!
