can someone send a few pics of the water system, coming from the jet to the motor then back out to the headers.... im having trouble dialing this in... what kind of valves should i be using to regulate the water to the headers... please help!!

I have had my issues in the same manner and i am coming up short with answers. I am in the process of fixing mine as well as i have several issues going at the same time.

Scenerio #1 - Starting with a gate (or globe) valve at the jet to regulate the initial flow into the motor. Then on the "Out" side of things run a straight dump over board. as for the headers, rum an angle stop (just like under your sink) to the Bassett T-Valve then to the headers.
        The theory here is to keep the ange stop wide open and set your temp at idle with the valve at the jet. Then adjust the angle stop to barely spit water at idle and to mist at about 2K RPM. as you pinch down on the ange stop, you may need to re-adjust the valve at the jet to adjust your idle temp.

Scenerio #2 - Run a pressure relief valve at the jet adjusted to 20# or so to regulate the amount of pressure being shot into the engine and a valve on the dump side.

I am having heating issues with my pig but i am pretty sure i am blocked somewhere. I asked the same question you did and i got very little response. Check out Bassett sites FAQ and also check out Jet boat performance site. Tom has the pressure relief set up and appearantly swears by it.

Let me know what you find as I would like to set mine up as well and be done with it.

If I could post a pic here I would.  If you have bassett style injected headers you'll want a bassett t valve.  So it's water off/out of the jet(yes a gate valve there)  that line gets' t'd and plumbed into your inlet plates(where water pump would be). Then you'll need 2 outlets from either therm housing or out of intake by therm. housing. 1 will be your dump line. the other gets the bassett t valve and to you injection lines.  A gate valve on the dump line will allow you to regulate at what rpm's the headers become "wet"  the more you close the valve the sooner water enters the headers. If your not takling about injected headers then I just killed 5 min. lol

from the pump i got a gate valve then to a T up to the water pump plate. then i dump from one side of my t-stat housing (no valve) off the other port of the t-stat housing, i run to a header control valve, then to the bassett T-valve, then to the headers.

hope this helps

hey rod, how long does it take to overheat? and how did u remove the sand?  Im out in rancho cucamonga, but I work out in rancho mirage alot, maybe sometime I could come out and help u figure it out.

yessssssss,,, thanks alot ralph and tjs.. it all makes sense now.. my problem was i didnt have the ball and spring in my t valve ... i think im going to get that other valve and run into the front to help control the water temp too...
