    Default About to run em dry

    Hey guys, I have another question regarding water flow to the headers. Its a set of bassett long collectors that came with this rogers project. I have the "T", which has a new ball and spring in it. #8 lines feeding headers, and a ball valve on the thermostat housing. When we run this setup on the hose, (about 6 psi) and when I unseat the ball valve even just a hair, it immediately fills the header tubes and water is pouring out the drain holes. It does this with both my dump lines fully open. Am I doing something wrong? I know I have the spring in the T in the right direction, and I cant figure this out. Im gonna try and attach a picture of my set up so you guys can see. Any help is going to be greatly appreciated.

    Welcome to the threads, I don't see any control for water to the headers?

    Afish85,
    Ball valves aren't for regulating flow, just on/off. Buy yourself a simple "metering" valve (more than 2 full turns) and your done.

    Or just run em dry like!

    bassetts and the "garden hose" dont get along to well if your not regulating the water flow to the engine. Run the headers dry on the hose so you dont hydrolock the engine .

    Just curious where the two "gated valves/hoses" coming from the devider T run to ? if they are indeed overboard dumps they should be OK but...

    Im sorry guys, I added the ball valve after that photo was taken. It comes off the center of the Tstat housing. My bad. And I have a pressure regulator inline, and a hose hook up/shutoff/ and an oh crap handle on the jet pump feed line.

    So where do the other two lines go ?

    Theres no need to restrict or shut off the dump lines. When the motor is on the hose, the water should spew out of the dump lines, just as Futs mentioned. The hoses look new, but the set-up looks like it's too much. I like to keep it simple, and its never hurt my motor. Each boater has a specific way of running their cooling system too.

    Are you "sure" the T-valve is assembled correctly, with the ball on the little end of the spring?

    Just asking, as I snotted up a fresh 429 few years ago because I trusted the plumbing job on my boat was done correctly.

    I also install a 1/8th pipe plug in the #8 hose fitting to the water injector lines and dill a .060 hole in it to restrict water. {one each side]

    the bassett t is "pressure opened", meaning that when the pressure into the t rises to a certain point, spring pressure is exceeded and the valve opens. with those 2 dump valves you have in the engine outlet (and god knows what other restrictions there are in the dump lines), the city water pressure can exceed the pressure needed to open the bassett. actually, city water pressure could easily exceed the basset t opening pressure even with the valves wide open. consequently, there could be no problem with the basset t functioning properly - the applied pressure is simply high enough to open it. so... you need to be very very careful about running the thing on a city water hose, and don't use those 2 valves to pressurize the engine.

    personally, i'd get rid of those 2 outlet valves - you don't need 'em. ball valves -can- be used to throttle flow, it's just more desirable to use a globe or gate valve. i used a ball valve for years to open/close water to the headers, except it was under my seat.

    someone mentioned a restriction to the bassett manifold. that's a good practice. the other thing you could do is remove all 8 1/8 pipe adapters from the manifolds to the headers, braze them over, and drill each 0.040, 0.045. you don't want a ton of water pouring into the headers.

    X2 but i used a 7/16" set screw in the brass fitting at the header lines with a .090 hole and tapped the fitting for the set screw!


    SOMEONE SAID YOU CAN'T TAKE IT WITH YOU! SO,IM BURNING IT UP ONE GALLON AT A TIME!

    Did this work good for you WT? Too much or not enough? This is exactly
    how i'm setting up my Rewarders w/ a Moroso solenoid valve & RPM switch. The holes pretty small in the -8 fitting w/ the restrictor, just
    wondering what I'm going to get??
