Super Jet jetworks flow control valve

I am trying to set up my flow control valve. Most seem to set it at 3 or 4 psi. So at that pressure the ball seals off the flow going to the water box and goes out the pisser? When I put my pressure tester on there it always plugs the flow no mater where I turn it. It seem that as soon as I put pressure to it it stops the flow. I understand this would be good to keep the water box from filling at idle but how about when your at mid or full throttle?

i adjusted mine while it was on the trailer. unhook it from the exit side of the fcv and hold it over the side of the boat. you can hit the throttle and physically see when it opens. i have mine set to open right after 1/4 throttle. i have no clue what psi its at, but i know it opens at 1/4 throttle. i also had to cut half of a coil off the spring because the pressure in my cooling system is low with dual cooling and pissers. this is the way jetworks said was the best to get it tuned right. i also have a 2mm restrictor right before the stinger so when it does open it doesnt dump gallons in the watter box.

I said f it and picked up my own flow controller from home depot. Only cost 5 bucks. I think my jetworks valve is missing something on the inside. I don't know. I want to try it out tomorrow and I don't want to wait for a new valve. I guess the weather is suppose to be windy tomorrow so maybe not.

I place mine upline before the pisser. This allows me to see when it is working as it blowsout the pisser. The other thing is with it placed in this position is it ads more pressure instead of going out the pisser. Better for low end power in the factory pipe.

That is acting as a restricter, not a fcv. Most skis end up needing both on the stinger.

Did you notice a difference once you put the restrictor in? I'm running dual cooling with a FCV and adjusted mine the same way on the trailer. I still think its not tuned in 100% though. I was told to run a 2mm after the FCV and a 4mm on the other pisser coming off the head. I never did it though, didn't think it was that necessary but maybe it is?

a fcv is designed to restrict the flow of water going to your stinger/waterbox at idle so it doesnt fill up. not to keep pressure in your cooling system. but yes having pressure in you head pipe make the orifices more tunable.

i cant say because i did it this way from the start but yes a 2mm restrictor after the fcv should help. as for the 4 mm restrictor, you may or may not need it depending on your cooling.

I know what it's main purpose is. My point was by placing it between the head pipe exit and before the pisser will allow you to see when it is opening as well as adding pressure to the cooling system just off idle. This is only good if your running dual cooling as you still want water to flow at idle.

Well I took it out for it maiden voyage today. There is definitely something wrong with it besides the flow controller. I get the feeling I'm going to be taking all back apart.

I was under the impression this was tuned and ready to go. The low end was rough the whole time but it cleared out in the mid range when I feathered the throttle. After about 15 min it started running really terrible no matter what I did so I headed back to the dock in case some thing bad was about to happen. I emailed art and I will try to call him tomorrow. The good thing is that we should have clear sunny skies for the next few days. That should make water testing a little more pleasurable.

get rid of the crappy restrictor and put the flow valve on and check it the way tzane told you too. you are going to melt or blow cooling lines with that 5.00 POS!!!

I'm pretty sure I'm not going to melt any lines or couples with my pos restrictor. Like I said there are other problems that need to be dealt with before I worry about my pos restrictor.

when matt helps you i am sure he will throw away the restictor, it works nothing like the flow valve. some people.......ask me how i know you will over heat over restrict and blow lines. actually i will tell you, because some idiot that use to ride with us did the same thing and instead of buying one off my buddy, he use the same restrictor and f-ed his :):):):) up pretty quick. not saying your an idiot even though you ditched the flow valve for a 5.00 restrictor which is a dumbass move.
