The Do and Do not in a alky injection system
Do:
-good installation - soldered wire connections + heat shrink
-good failsafe
-a valved system to cut off the injection of water/meth to prevent run-on or the result might be an IC full of methanol.

-educate yourself about meth injection. Good reference material from Richard@Aquamist, read, digest and ask lots of questions!
https://www.evolutionm.net/forums/sh...d.php?t=292953 - all things meth injection
https://www.evolutionm.net/forums/sh...d.php?t=177646 - all things failsafe
-WAI Manufacturers should add a relay so WAI can draw power directly from the battery. Cost more but good reliability long term for the end user.
-check you methanol if you buy it from a race shop from a open drum
https://www.evolutionm.net/forums/sh...ighlight=milky
Do not:
-Draw your WAI system's +12v supply from the OE harness. Use a relay. 10amp is a great deal of current.
-Don't use contaminated methanol. Check it for clarity with water.
I'll update this as more ideas pour in

Hi guz_man, both the aquamist HFS systems, like mrMTB mentioned, are valved.
HFS-1: does not need to react fast because it is a predictable on/off injection - uses a MSV, medium speed vlave
HFS-5: because of the injector duty mirroring operation - uses a high speed valve that is capable of pulsing at 250 times a second to keep up with the positive and negative transients seen in normal driving.
Here is a video of it in action - on the left. The system on the right is a valveless/checkvalve system - there will be injectant jetting/dribbling out will the line pressure is reduced to the cracking pressure of the checkvalve.

Yea I think one of the biggest issues with kits is poor installs and then it quickly gets blamed on the kit...people don't always understand the importance of wiring up kits properly...

Don't...

DO...
WAI Manufacturers should add a relay so WAI can draw power directly from the battery. Cost more but good reliability long term for the end user.
