What are the current options for high speed valves? My ECU has an output that pulse at the same rate as the secondary injectors. My theory is that by using this, I will inject a proportionate amount of water to fuel no matter what. This way tuning will be easier and more consistent. (or so the hope is)

Also on a side note, how do the pressure switches in the pump operate? Is it if the pump is on, but pressure >150 the pump power is cut or does it operate another way?

the fjo solenoids have the nozzles attaced directly to the solenoid, the s-hsv has a line running to any nozzle you choose. i believe thet eh s-hsv is normally trunk mounted and the fjo solenoid is mounted directly to the intake pipe. The fjo design seems better to me but i havent gotten my setup to test it so im kinda talking out of my butt on this one. just my $.02

 

there are 2 types of pumps used for methanol/water injection:
1 - on-demand type - uses a built in switch to cut off power to pump once pressure is reached, the "dead band" from the swtiching causes pressure swings and also has detrimental effect of lessening longevity due to very constant 0 to full power operation.

2 - bypass type - pump stays on for the duration of the injection even, pressure regulation is done by "preset" internal pressure regulating valves.

here is a video demonstrating this:
left = bypass pump
right = on-demand pump

With our S-HSV you can mount it directly to the nozzle if you wish. We provide the hardware to connect it right at the pump as it makes it easier for install. The customer CAN however mount it in the engine bay, we provide fittings to install it in the engine bay if you wish, but we dont provide mounting brackets, thats why we have it at the pump.

The valve manifold is very light and small so its pretty easy to mount. There are advantages and disadvantages to trunk vs engine bay.

Thanks everybody.

Slowcar- that video is a great help, thanks.

Coolingmist- is it possible to use the S-HSV with a standard PWM control?

The thing I don't like about the FJO valve is that in order to change flow, I would have to change the entire expensive valve, I couldn't change it with a simple nozzle change.

 

the fjo system uses BETE nozzles - not sure whether it is the P or PJ series

just switch nozzle out of the solenoid valve body to change flow rate

one word of caution...the pin over the BETE nozzle is fragile, a slight misalignment over the orifice will cause you to lose atomization.

You can always use the time proven HAGO nozzles in place of the "pin type" BETE

forgot to say...
due to the design of the hago...its got a long filter screen behind the nozzle, you will need to fab a extension to make it work.

hago nozzle -> extension for filter clearance -> solenoid valve

 

Our valve is very different from any other you will see on the market. It has 1 moving part, an armature. The more current that is sent to the valve makes the armature flex..open to a certain position.

It was designed to work with our controller. You would need to be running atleast 400 hertz for the valve to even start flowing. In otherwords, Vari-Cool will PWM it fine, if you try a different device it may not work as well.

 

have you looked at the aquamist FiA2/HSV setup? It will do exactly what you want, maintain a constant water to fuel ratio

 

Does anyone know if the snow performance high flow valves function similar to the aquamist and cooling mist high speed valves in this PWM control application?

^The water/meth injection community appears to be picking up its game with improved offerings over the years. I believe the answer to your question is likely, "Yes".

I went w a similar offering from ProMeth. Feel free to give Rodney a call, and he'll be happy to answer your questions I'm sure. Rodney has been doing this for many years, and is quite knowledgable overall.

Note: Here is how I'll be mounting the injection nozzles; post-IC ahead of the throttle body elbow. The position of the coupler/nozzles assy is actually meant to face against the air flow direction to improve overall atomization effect.
