I am doing some things to my superjet this winter. one of the things I was looking at was a flow control valve. ive heard some people like them and think they are great and others not so much. would this be something I should get and try out or just stay away from it? thanks for help

They are a great modification for the money if you have an aftermarket exhaust. Keeps your waterbox from loading up at lower RPM, snappier bottom end since you don't need to blast the water out that would normally accumulate.

If you get the adjustable one that you change just by twisting it it's pretty straightforward. It's not your pipe you'd get hot, it's your waterbox. I ride 4+ hours at a time sometimes chasing boats and I've had no problems with overheating my waterbox ever since I got it setup right.
It's not harmful to your ski at all as long as you're getting enough water to your waterbox so it doesn't overheat.
The flow control valve controls when water is let into the waterbox, and how much you twist it determines at what rpm it opens up.
The best way to check it out and determine how much to twist it is by taking the cooling line off of the stinger, and holding the line overboard and playing with the throttle to see when it opens up. That's what I did.
And what a great time to start man! Ask as many questions as ya want

It's a 1995 square, but yeah that's my ride. It's modded alot more than it was in that picture though. My build thread is here: http://www.x-h2o.com/index.php?thre...oam-engine-rebuild-all-the-good-stuff.146094/

so just a question.... wouldn't a nozzle with different jets more like nitrous give us better results than a pvc twist valve mid stream in the water line? i know its cheaper and simpler the home depot way but the way pressure works it means we are getting an inconsistent dribble instead of a good even spray.

Ideal is a jet after the flow control valve, like the PFP pipe, but that's not necessary for the common b-pipe.
A wet pipe needs enough water to keep it around 200F, that takes a hole approximately .050. You dont want the rest of the exhaust that hot so add a little more water at the stinger. A properly designed waterbox (stock) will evacuate nearly all the water above idle. Most noisy aftermarket boxes need a couple of full throttle blips to clear them. I know more than one rider that removed the FCV because it made their TDR boxes too loud most of the time. A 2-3mm jet at the stinger with a pisser in line will provide just enough water to keep the exhaust cool and quiet.

You want the pipe to be hot. Get a temp sticker or bring the laser temp gun out to the lake and see exactly what the temp is.
What would be to hot? If you know
