Next week I am going to try to add one of the extra washers to try to dry the waterbox out some. Right now I am running the Jetworks as they ship it.

WATER SHOULD START TO FLOW AT 2500-3000RPM. THIS IS WHERE ART AT JETWORKS TOLD ME TO SET IT:biggthumpup: .

DO you just keep it on the trailer unhook the water line after the restrictor and rev it up to see where it starts spitting. I assume you would need to hook the tiny tac up to make sure it was working correctly.

I am about to install mine just wanting to know this information also.

I was told those things jam up if you ride in the surf a lot, can anyone verify that for me.

3.5 psi I think this is where Art told me the one with washers came set at. You can check them with a popoff guage. I use the Jetworks pro so I can just twist it to adjust:biggthumpup: Basically the way he described to me how to adjust it would be, If you were cruising thru a no wake zone you would want it to open just about the speed you would be thinking the cops might give you a ticket.

No that would not work. The water pressure is created by the pump when you ride, if you put it on a hose the pressure would be whatever the hose is.

You are all making this way too hard you aren't trying to land on the moon just set get water to push a little ball against a spring. Set it go ride, try a new setting go ride until you get a setting you like.

I think he is talking about having on the trailer backed into the water. Although I did find it difficult to tune on the trailer. Best way I found was to ride around with the hood off and use clear cooling hoses.
 
just disconnect the valve from the pipe and ride with the hood off. Just keep going back to shore and adjusting til you get it where you want it. Should have spent the extra like 5 dollars and got the pro series with the twist adjust. So easy.
 
Yes I was refering to running it on the trailer.. Heck I don't even have a hose connector..

But anyhow I would run the water box completely dry if I wasn't worried about melting anything. How hot will a waterbox get with a B pipe. I know it has to do with how much water you have going through the pipe but I think I only have one screw open about 1/2 a turn. Is that enough water to keep things from boiling?

You would have to have the pipe so wet that you would lose performance. If you run the waterbox dry you will melt the glue out of a stocker and anything that is touching the metal outlets will melt, IE steering cable, wiring, etc. Last but not least you will probably destroy that $100 long exhaust hose. Spend the $$ and get the Jetworks valve and fine tune your BRAP!!
 
I have the valve I was just wondering what kind of water is needed. I have never ran a wet pipe I have always ran dry pipes and you HAVE to have water in that thing or everything melts. Infact paint smoke rolls out from under the hood if you dry the box out too much... :biggrin:
 
I'm getting confused now. I just bought the pro series but haven't installed it yet because it's still freezing here. Anyway, Is there a much higher risk of burning up the waterbox and exhaust hoses while running the Jetworks valve with a dry pipe ? If so what's the best way to prevent this ?

Im curious about this too..
 
I just talked to Art and he told me with a dry pipe and a single cooling line to put a 3mm restrictor in your overboard that comes off your head forcing more water to your flow control valve... Water takes the easiest route so too much going overboard may be a bad thing with a dry pipe.
 
When I didn't run a flowvalve or restrictor with my dry pipe. I noticed a lot of water that would blow out of the exhaust when it came off of idle.

I dryed my waterbox out before I installed the dual exhaust. That is when I started melting paint. I restricted water flow to the stinger with a hose clamp. I only a a bit of water runing through it which was fine at low RPM's but after a WOT burst there was only steam coming out of the exhaust. I knew that was too hot but by the time I got back the paint was baked black near the stinger.
