T-valve

[blown428fe]

Do I need to regulate the water off the T-valve to the headers with shut-offs or just run straight from valve?

needs to be regulated.

Checkh this link to Basset to see how they recommend to run your plumbing and other tips.http://www.bassettracing.com/newpage7.htm#Jet%20Water%20Injected%20Installation
This is how I run my water lines as recommended by Basset.When I purchased my jet it was plumbed with direct pressure into the motor and all the water out going into the headers it worked but was not correct.Luckily I never had a revision problem with all that water in the headers.

My headers are dry so take my advice with a grain of salt. I'd regulate the water right off the pump, that way you'll never have to worry about high pressure causing reversion problems, milk shake problem, and you'll have an easier time getting that motor up to a good operating temp. The regulator from Hi-Tech has always worked well for me but there are plenty of home made ones running around that work pretty well-Aluminum Squirt

I think his question is does he have to put ball regulators after the t valve. The answer imo is no. Typically as recommended by Bassett is a shut off valve in the dump line. I however do not use one. I actually shim the spring in the t valve so water comes in later.

I think you're right Tman, I was writing at 1AM, so the brain was working less than my usualy low level. Anyway, if you have not regulated the incoming water, I would look into that. As far as the water to your headers, I will refrain from answering as mine are dry-Aluminum Squirt

i do run gate valves at each header after the t-valve.i like alittle steam comin out and puttin a gate valve in frt. of the t-valve didn't work for me.it let too much threw.wish i had a thermostat set-up,they're nice!

I noticed lots of steam out of my exhaust this last weekend w/the T-valve ~90% open (still running a bit cold.) By bypassing this and running a secondary to the headers, will this reduce the steam? Or am I waaaaayyyy off? BTW, my line runs straight though the block and out the headers...

just get a Banderlog valve and forget about all those valves to the headers. Just hook it up as directed and go.

My boat was hooked up like this by the previous owner except they had the Basset T in the line feeding the engine and spliting it into the block with no restriction on the lines to the headers.Alot of water would pour out the headers at idle and that is N.F.G..
I connected my jet boat water lines as recomened by Basset.There is a gate valve in the line from the pump.With this valve you can restrict the water flowing into the motor and build more engine temp but it will get hot when idiling through no wake zones.After the inlet gate valve T the lines into the block water pump holes.Water comes out the thermostat housing one line goes to the Basset T and out to the headers.The other line on the thermostat housing goes out thru another gate valve then dumps overboard.You can adjust the overboard dump valve to give the headers water at the desired rpm.I ran my boat with this setup last year with no problems.

This may open a can o worms. When running a good loader or shoe at high speed there is sufficient pressure in the intake and in the bowl to hold the T valve open way after you have let off the throttle. That's why we all let off easy isn't it? Try it sometime--- let off quick at high or medium speed, see if your motor dies from too much water in the pipes. You may even hear a nasty rattle that sounds like detonation. Water in the cyls. I got tired of sticking T valves, water at idle, easing off gradually at no wake zones. Put in a manual valve, I can now run full out, shut the valve, lift the foot, and settle into a nice idle as I coast out. I can't tell you how many guys I watch load onto there trailers with throttle, the T valve opens, the boat slides onto the trailer stops, and they shut the motor off. Have you ever watched just how long it takes for the steam to stop after you idle down? If it ain't dry when you shut the key off, you will have water in the cyls. Rust. Another bonus with a manual valve is you can shut the water off for a good top end boost if you have coated pipes. Don't recommend that with chrome though. If you have chrome, (I do) don't forget to turn the water on when you take off. It will blue the pipes very quickly.

I guess I have water in the engine! Chit :mad: I'll have to look into changing the current setup.

Legal Chemistry, I think you must be talking about a gate valve or ball valve. The "T-Valve" used with headers is not an adjustable valve. It is a t-shaped unit with a spring-loaded ball inside that does double duty. One, it shuts off water to headers below a set pressure(determined by the spring pressure). Two, it takes a single feed line and splits it via the "T" shape to the left and right header injection lines. Your description doesn't match this.
Did you check the link to Basset Racing posted above? If you scroll down to the bottom of that page you will see a diagram of the "basic" header water plumbing layout.
BTW, when you say "Headers" you do mean true individual tube headers and not any of the cast aluminum exhausts, either center rise or "log"-style, correct?

I always ran the line up to the driver seat with a valve. That way I have total control over my own desteny..... just my 2 cents
Exactly :) :)

[Legal Chemistry]

You're right OldSquirt. It is the gate valve not the T-valve. All the water comes in through the gate->block->exhaust (non-header.) I guess I was reading too fast and typing w/o thinking it though. Thanks!
