Water routing for dual cooled SXR with wet pipe

There are two types of dual cooling... There is redundant cooling meaning if one line gets clogged, you have a backup. The other type is where one cooling line is dedicated to the engine and the other is dedicated to the pipe. This is a super ghetto drawing that JJC568 and I came up with a while back for redundant cooling. It illustrates where things go at least.

I have also seen some setups where they tapped the cylinder and installed the fitting there instead of the manifold.

Good info and it would certainly make getting to the connections easy but I think I'll pass on that personally. Ignoring that the cylinder actually needs to be drilled :eek:mfg:, it just seems like the water wouldn't move as well in the exhaust manifold.

What are you running on the engine? I am running a ADA head with 175 comp and a wetpipe as well. I am only running single cooling with no issues at all. The only thing that I may do is run dual cooling where the one input is for the pipe and one for the engine. Most SXRs that do run true dual cooling really do not need to.

Do you want true dual cooling because you think it's cool? I can understand redundant dual cooling for the sake of having insurance. However, I have a hard time believing anyone in Canada needs any form of dual cooling. Maybe if you ran wide open for extended periods of time on a seriously modified motor. Other than that, the water is so cool up there that a semi clogged cooling line would still probably offer enough to keep the engine from getting too hot.
 
i just bought a dual cooling kit and would like true dual cooling i was just looking for any one who has already done this set up which im sure many people on here have and was looking for some help of advice on the set up thanks
 
On the 800 SXR it is common to just leave the stock aluminum line. The aluminum tube has the ends too small but you can enlarge the ends and use 1/2 inch hose and switch to real 1/2 inch fittings, 1/4 npt-1/2 barbs. If the hose fits slightly loose just use double clamp. The inside diameter of the fittings and the bends are more of a resistance than the actual inside diameter of the hose.
 
when i was down at the surf slam this year everybody was running dual cooling with only a head and pipe and all of them said the more water u can give them the better so i would like to try thanks

What type of dual cooling were they running? Was it two cooling lines to the engine or one for the pipe and one for the engine?

same setup here, I would run them like this:

two cooling lines from the pump to seperate inlets on your exhaust manifold, plug the middle one and use the side holes, may have to tap them.

from the head have one pissing overboard and one flowing to the bottom fitting on your factory tuneable haedpipe

run the top fitting on the factory tuneable headpipe overboard and teeing off to the stinger.

this setup seems to run great on my boat.
 
the first drawing is exactly how mine is set up. run both cooling lines into the bottom of the factory pipe exhaust mani. Its easier to change the pump fitting to 1/2"cut off both sides of the thru hull cooling line, & install 1/2" line to the engine.
