The Do and Do not in a alky injection system

SlowCar · Jan 1, 2008, 07:45 PM

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.
Alky kit w/o solenoid valve...not good! - Post #30

-educate yourself about meth injection. Good reference material from Richard@Aquamist, read, digest and ask lots of questions!
Indepth study of WAI injection systems - all things meth injection
There are failsafes, failsafes and failsafes... - 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
Methanol + water = 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

good post Abner.. thank you

does the the HFS-5 come with the valved system?

mrMTB · Jan 2, 2008, 07:30 AM

Yes, the HFS-1 and HFS-5 use a high-speed valve to control the flow.

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.

excellent..

thanks MrMTB and Abner...

Next time you are at Mynes, do say hi to Mike and Jason for me

Guz Man · Jan 2, 2008, 08:24 AM

HAHa.... mike actually is a buddy of mine.. all of my mods are from him.. i will sure get him the message and to Jason..

did you get my Pm? if so.. please advise..

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...

SlowCar · Jan 3, 2008, 04:46 AM

its critical to do it once, do it right.

This thread is great for all "WAI manufacturers" and "USERS".

You are absolutely correct.

updated. thx for inputs

thank god i got the HFS-5

Great video! Makes me wonder how my Snow kit is performing when it shuts off... Does it leak like that... Hmmm...
