flow control valve.....

[the WaTeRhAwK]

anyone ever run a flow control valve between the head and the header pipe?

thanx.

It will work but you're gonna need a capacitor.

oh geez, here we go....

If you're running a head with single cooling, this might not be a good idea.

What's wrong with running the FCV before the stinger inlet and restricting the pisser?

#.0, just fyi, youre asking a very logical question to someone that is the mental equivalent of a bottle cap.:shhh:

well, I have an old style chamber on one of my 550's with no stinger fitting. the water dumps directly full flow into the chamber. which helps with bottom end tremendously, but it doesn't do crap for top end rpms because the full water flow keeps the pipe cooled off too much to peak out well. I've been thinking about installing a fitting on the stinger and just keep using the limiting valve I've been using between the head and the head pipe adjusted to minimize the flow into the chamber, but it doesn't hit as well on the bottom unless it dumps full flow. I'd like to figure out a way (short of installing a ECWI) to mechanically allow the water to dump from the headpipe into the chamber until upper midrange, then have it switch to being diverted to the stinger, and cut down on the amount coming from the headpipe (like the newer style setups.)

I want to figure out a way to more or less get the reverse effect of a flow control valve going from the head to the head pipe, and then divert the flow to the stinger as the rpms come up past midrange.
















(speak for yourself, charlie... you do that quite often.......you've been cracking way too many bottle caps. give it a rest

Weld a port in the stinger tee it off of the headpipe and restrict the headpipe as needed !

I already have that setup on another ski. it's basically a newer style setup with a flow control valve between the head pipe and the stinger fitting, and I use a limiting valve between the head and the headpipe, but it doesn't dump like it needs to going into the chamber. if I open the limiting valve enough to where it helps the bottom end good, it cools the pipe too much at the top.

Limit the flow to the headpipe don't adjust both at the same time. I am just offering a suggestion to your problem I am not saying it is the cure just sharing thought's of mine with you. Good luck

thanks, and much appreciated.

limiting the flow to the head pipe takes away bottom end. trying to figure out a way to make it dump until upper midrange, then limit it while dumping at the stinger.

I'm thinking about getting another flow control valve and try somehow modifying it to act in reverse , or something.

That actually can be done fairly simple

I'm intrigued. what would you do to modify the valve? put another smaller spring on the opposite side of the ball?

 

[Motorheads5]

It is pretty simple really have a check plate not a ball and drill port's around the outside of the check disc and as soon as the pressure or flow exceed's the capacity of the holes it moves against the seat overriding the spring and stop's the flow.

thats a good idea, although I don't want to completely stop the flow, the coupler will melt.

I think I'm going to experiment with plastic, and if it works with a hose, I will transfer the parts to metal. you got the wheels turning mh, thanks a bunch bro.

What about using another flow valve as a pressure relief valve in your head pipe circuit. This would allow more water at the lower r's like you want but when the pressure rises it opens and releases some of the pressure so as to not over flow into the head pipe orifice an kill your top end..

 

[Scorn800]

WAD does that mean your going to actually ride your 550 instead of just typing about it?
Have you rode in the last 5 years?

 

[sflsurfrider]

i think he should go to pwct and ask mr TEE what his thoughts are.

that's the idea. but I don't know of an existing valve that will do that.

Since it looks like you are currently controlling the amount of water flow into the head pipe I was saying to leave it full flow into the head pipe and control when you want to bypass a good portion of the water to prevent over loading the chamber with too much water at higher rpms. This will allow a bigger orifice at the spray point in the headpipe. By altering the orifce diameter and relief pressure point you should be able to dial it in.
