Ok I just ran a very crude non-scientific flow test on one of my Coolingmist's M2 nozzles with some filtered water.

Setup: 250psi pump at the factory 200psi setting and a S-HSV valve, 22psi checkvalve and the M2 nozzle.

I just applied constant 12V directly from the battery to both the pump and the valve with no controller since I don't have the system fully installed yet. I let the nozzle spray into a 10oz bottle until full and timed it to 1m 40s give or take a few.

It came up to about 175cc/min which is right where they're rated at.

 

were did you get a 200+ psi pump

 

Great to hear that you have started your testing.

 

It's a Coolingmist pump, they recently started selling them

 

That's good to know.

Where do you have coolingmist pump mounted? I just got my kit and I'm trying to decide where to mount the pump, it's bigger than I thought it was.

I had intially thought of using the washer fluid tank, but I can't find a good place to mount the pump below it. Right now the plan is to mount it where the wiper fluid tank was, and put the tank that came with the kit where the battery was. This may give me more options for tank size later on if I want to upgrade.

 

i also would like to know where everyone is mounting their pumps? (aka the people without the trunk tank)

 

I mounted mine where the stock washer fluid tank goes. It fit's right infront of the fender liner, but barely. Pretty much the only place I could find without cutting anything, except for on the body beside the spark plugs, and that just seemed to hard to get to, especially with a drill.

 

The next non-scienific test would be keeping the pump on and manually activating (rapid power on/off) the S-HSV and see how quickey it opens and closes.

 

Here is simple, non scientific test, on our HSV (high speed valve). Watch the spray jet on the left. It synchronizes with the blue led strip bar (in the middle) very accurately. Notice there are no drips - instant "on" and instant "off".

If your set up cannot meet this basic test, you are not going to utilise the Summer properly.

 

Please ignore the system on the right (valve-less) - it has nothing to do with your test.

 

question, if you just hooked it up without a controller straight to a power supply wouldnt it do the full 250psi instead of 200?

 

The water pump pressure is controller by a mechanical "pressure relief" built into the head of the pump. As long as there is a 12V supply, the pump can only produce whatever the valve is set to.

An electronic controller (motor speed controller) can only reduce the set pressure from the mechanical setting.

 

Any more test updates?

 

so the 250 psi pump i have just connecting it to a 12v will only do max 200psi but if i connect it to my vari unit and set it to the max ill get 250 out of it?.. just a question since i never installed this before, how do i install the nozzel to the TB?

 

You motor speed controller can only bring the maximum pressure down from the maximum.

If you want to incease the maximum pressure to 250psi, you need to use an 1/16" allen key to alter the by-pass valve pressure. (clockwise). I am nort sure how many turns, need to ask your supplier.

 

Turn the hex key about 1 to 1.5 turns clockwise to reach the 250 PSI.

 

ok so even on the controller if you put it to run at 100% its only doing 200psi.. thats good to know
