Varicool S-HSV Kits available Soon!

[coolingmist]

Our new kits are called Varicool S-HSV. That stands for Super High Speed Valves. The brains of the system is our Varicool Digital Controller, however in this setup Varicool is matched with two valves that are extremely fast reacting.

In a traditional progressive system the controller will PWM the pump. This makes the pump motor spin fast or slow. The faster it spins the more flow you get. The down side to this is the slow reaction time due to the spool up of the pump. This will affect any progressive system that PWMs the pump, regardless of manufacturer.

This system works different. The pump always runs at full pressure (100% dutycycle) giving it 130 to 140 psi. When its time for the system to activate a digital signal is sent to to each of the valves. The signal that the valves get will determine how much flow. The reaction time of the valve is approx 3 ms for open and close (1.5 ms reaction). That means the systems can go from 0 to full flow back to zero flow in 1/333rd of a second. You will get far better speed and performance with this style kit than with a regular progressive kit.

In addition to that, we took measures to make sure this system meets our standards for what we call "brainless" installation. You will not need to use the free software (unless you want to), requires only switched ignition and ground electrical connections, to be strapped down and to be given a boost source (or 0-5V or both).

If there are any questions about our new technology please let us know. We spent alot of time designing and testing this system. We are the only US based company to have a high speed valve style system. Its also important to note that this will NOT replace our current progressive kits, we will continue to sell our regular progressive kits as well.

Any thought given to or longevity data available for the pumps in these systems where

The pump always runs at full pressure (100% dutycycle) giving it 130 to 140 psi.

Is the pump a Shurflo 8000 series? I assume the pump is warranted for one year. Mines' 8 yrs old. Seems like the life expectancy would be much less if I understand how this system operates.

Actually the life expectancy will be the same or very similar. In a shurflo 8000 series demand type system the pump has a pressure switch that shuts the system off at a specific pressure. For example at 150 psi it would shut off, then it would turn back on around 80 or 90 psi. This particular kit is regulated to when its running the pump will always be a full pressure. Once the line reaches full pressure the system would shut off, but the pump and the valve do not pulse. In other words the pump and valve operate at the same pressure. When you are not in boost or when the system is not activated the pump is off. When the system is activated the pump will always be on, no cycyling. There is absolutly zero lag because there is the valve opens so fast.


Hope that was not too confusing.

According to the link, these new kits are free so I'll take one of each.

[coolingmist]

nothing in this world is free

We will have pricing shortly, probably early to mid next week.

Here are some vids I took today to demonstrate the Amazing atomization of our system. You will also notice there is no disruption in flow. We designed the curve so there is no deadband the curve matches our controller/pump exactly. The system does not pulse, you get smooth, consistent flow and perfect atomization with super response time. You will see the flow increase and decrease in some of these videos and watch how the system does this.

As time goes by we will be taking some better videos but these show some nice features

My compliments to your innovation. I saw the video and I saw the nozzles produce different flow rates but I cannot understand how this happens with the pump at 100% output all the time. I'm ASSuming that the S-HSV kit has more than one S-HSV right? How can flow be controlled by having a valve that is simply open or closed, something has to throttle the flow. Or is the S-HSV pulsed where higher flow would mean longer open pulses? I see you advertise 'No Pulses in flow' but I would guess if you can pulse the vavles fast enough it wouldn't show up as pulses in the flow. Fill us in on the details.

Thanks for the compliment, I greatly appreciate it.

I will have full details shortly as I release more specs but when I say no "pulsing" I mean the pump doesn't cycle on/off. When a pump cycles on and off the flow will pulse. This does stop that from happening. In most shurflo pumps if your injection nozzle is small enough (under 12 GPH) the pump will goto 130-150 psi, shut off and then not turn back on until about 80-90. This system keeps constant pressure to the pump so its ready when needed.

The S-HSV does have 2 valves inline to a manifold this was only for flow reasons. When you increase the size of the valve you will get more flow but you will have a slower valve. Our solution was to add a 2nd valve of the same small size. We did not want to compromize. The valve is incredibly fast for sure. I will say that this was a very difficult product to engineer. To get a super fast small valve with a perfect cv factor and enough flow is not an easy thing to do. Everytime we got more flow, the cv factor would suffer (cv factor affects the resolution). After many, many prototypes we got it right. We would not compromize on this, it had to perform and do things not yet seen in a system. The results will speak volumes. We will be announcing more details this week as well as having a pre-sale at a nice discount.

Just ordered one of these little buggers last night. I don't know much about cv factors or resolution all I can say and have said about anything I've bought for this car is I don't care what it costs It Better Work! So far I'm batting 0 so maybe this will work everyone gets a break sooner or later. And that tank of meth sitting next to that purple hot down pipe always makes me nervous so I got the trunk mounted steel braided hose option.

[coolingmist]

I appreciate the order. PM me about your current injector setup so I get an idea of what your looking for flow wise. Also, the system comes with 15 feet of hose, let me know if thats enough. I know you will like the system, its bad ass. CM.

[Steve Wood]

This looks like a very nice idea. Reading the faq, I notice that the pressure being run is in the 130 psi range. Is this a limitation of the valve design, or can it be increased? The guys that are running so fast on alky injection are pumping a lot of methanol at high boost, and, I believe are running somewhat more pressure. I understand pressure is a function of nozzle size as well as volume capacity of the pump

Also, I have come to believe that a non-linear flow curve is a benefit-particularly on street cars with tight converters...given this is not a pwm controller, are the same features available for custom tailoring the flow curve?

Steve,

I should make clear that this IS a PWM controller. Instead of PWM the pump, we PWM the valve. The flow curve default is Linear, however if you wish to make it non linear, just change the curve in the software.

And yes the flow capacity of the pump/nozzles/valve are key for the pressure. Shurflo 8000 pumps from most manufacturers have a 150 psi shutoff switch on the pump. This means the pump will cylce on/off. If the switch is bypassed then you will not have safety to shut the pump off if there is a clog on the nozzle.

If you think of the valve like a fuel injector able to open and close fast, but with the ability to partially open...as small as 1/32,000 of an inch you can see why the valve is so fast.

I know my answer is more confusion than answers I guess. What I am trying to say is that the flow of this system is very similar to the flow of a system that PWMs the valve. In the event that you need more flow, you can add a 2nd manifold if necessary...however it would be a rare case.

CM.

[Steve Wood]

No, you did not add confusion

I "believe" some are claiming pressures in the range of 200 psi, and, I "guessed" they were not using the bypass switch to get pressures in that range as I had not seen switches higher than 150#...I thought that might also eliminate the pressure swing that occurs from the wide gap between the on/off of the switch.

Again, I like the concept

[salvageV6]

People "claim" a lot of things on the internet.

Their claims just might not add up with a snubbed gauge and some accurate test methods.

Then again you might get those pressures more easily with a 16-18 volt battery system.

It's all in the presentation.

I only "believe" honest people.
