Other quick flow control question

[vomitspot]

im installing this little fella on a b pipe
motor and pipe are cooled seperatly
does the flow controler go before or after the t in the stinger line
seems if was after the t for stinger then it would not build the pressure to open , just divert out the bypass

I put mine after the tee to stinger with a pisser, so when it comes on at 1/4 throttle I have water going thought the whole system.

I put mine after the T, but run a restrictor on the line to the bypass, usually a 4mm restrictor. On my current build I might also install a 2mm restrictor after the flow control to limit the flow into my waterbox when the valve is open. If you do this you should probably run the inline part of the T to the bypass so small debris will go out the bypass rather than clogging the 2mm to the stinger.

 

[vomitspot]

did either of you test to see if it opens ?
just seems water is gonna take the easiest path and go to the bypass insted of building pressure and open the flow controler

 

[RSKI]

I did not test it, but I was thinking about it yesterday and on my current build I will test it for sure.

The water will take the path of last resistance, but the 4mm restrictor is there to build pressure as it restricts the flow, so the valve opens.

before the t. since it will not effect the cylinder cooling due to the dual lines in. builds pressure in the head pipe and then releases it for top end wave return . stinger should be dry until just off idle

 

[madscientist]

the idea is to dry it out at low rpms and soak it at yhr upper. the water at the stinger increases the speed of the back pressure wave and pushes the rpm up faster. the dry box lets the system flow faster of the bottom since it is not pushing all the water out of idle

Yes I tested it and with the tee due to the line of water going straight it wants to flow through the valve but I have it set at 1\4 throttle to open. I tested and it works great. I never did restrict the pisser line that that comes off the tee due to it working just fine without

If you did that your head pipe would have no cooling water going through it until you hit the throttle. Or am I misunderstanding you?

 

[vomitspot]

well if you have more pressure in the head pipe the more the water adj screws should spray into the chamber

 

[RSKI]

Agreed, but if the pressure isn't high enough to open the flow control valve at idle (with the fcv before the T) then the headpipe has no cooling flow going through it other than the tiny amount that is injected through the adj screws. You still need flow through the headpipe to cool it. I would think if the fcv was before the T there is no point in having it. It would either stop the flow to cool the headpipe (at idle) or be open all of the time since there is nowhere else for the water to go (except through the tiny adj screws like you said).

I have my FCV after the Tee and Jetworks needle valve controlling the flow to the pisser. Essential the needle valve is my adjustment for the FCV.

Ran the FCV after the Tee without the needle valve and all the water went out the pisser.

the head pipe will be getting all the water until the valve opens then the stinger and pisser will flow, giving you a visual of the valve opening. we are talking about a line into the rear of the pipe from the pump, then out the front to the fcv and to the pisser/stinger.


why would there not be water getting to the head pipe?

 

[madscientist]

vomit you are correct. call if you need to discuss it

The headpipe will be full of water, but there will be no flow. Without flow the water gets hot and has no cooling effect. Unless I'm completely misunderstanding you? You're saying in your setup your bypass only pisses water when your fcv is open (under throttle) correct?

 

[madscientist]

yes. it also increases the head pipe pressure that sprays in the headpipe. thus slowing the returning wave. most skis wont be ridden below a 1/4 throttle anyway. the cylinders will be cooled separately.

am i really that off the concept of how these work?

 

[TheBuzzard]

it goes after

 

[tor*p*do]

I run the line straight through the T to the FCV and stinger
the 90 degree side of the T goes to the pisser overboard
and this seems to work fine

I'm not saying yours is wrong by any means, just trying to explain why I ran mine after the T. I'm a noob and there isalways more than one way to do things like this.

 

[vomitspot]

i have always ran my fcv after the t in line to the stinger
but to me t just seems like it will not build any pressure if the water has somewhere else to flow
im going to try to install before the t to see if i like it better
even in no wake zones im over 1/4 throttle my skis dont idle what so ever
