FX-1 Fx1 dual cooling

[1fastsedan]

What are you guys doing for dual cooling? There is only one small cooling line and the larger bilge line. I want to set up my b pipe so that I have one cooling head and the other cooling pipe.

Where do you tap the pump?
do you run a reducer from the old bilge line so you can run a standard cooling hose?

I've never run dual cooling before, but the idea is to double the flow of water. water goes into the exhaust manifold, up through the cylinder to the head, then out . the manifold, cylinder and head are the hottest parts that need the most cooling. so you would have a double in on the mainifold and a double out on the head then you send one to the rest of the exhaust and the other out the side of the hull. in my opinion you don't need dual cooling unless you have a heavily modded engine.

I ran dual on my 650sx that way I knew if a pisser stopped I could trace it. The superjets have two thru hull fittings right? The diagram I found shows two lines going into the bottom of exhaust manifold each fed by their own thru hull fitting. So if I T the lines from the 1 hull fitting into the two exhaust manifold fittings, will that be enough water?

 

[fx1mark]

you have two fittings on your exhaust manifold? if I understand, you want to take the single water intake and split it to the two fittings? no problem with that. or you could just use one input and put a plugged piece of hose on the other.

It's a factory exhaust manifold. There are two fittings at the bottom. Here's how I plan to run it.
Thru hull goes to bottom of manifold.
Bottom of head pipe to back of 35cc head. Front of head out to pisser
top of head pipe to a T fitting which one side will go to pisser, other to the stinger/tail cone of pipe

If I am follwing you correctly, you should have 100% of your water flowing into your manifold, out of the head, and through the headpipe. once you come out of the bottom, of the headpipe, you can do what you want, as long as some of it goes to the waterbox. you got to have 100% flow not half going through the hot stuff. here's my motor. you can see the the water from the back of the head to the top of the headpipe, then the bottom of the headpipe to a split, half going to the waterbox and half out the pisser.

All stock factory pipe manifolds come with one fitting, all superjet, and fx1 hulls come with one cooling line thru the hull. When I built my fx1, I ran the second cooling line thru the stock bilge tube thru the hull.

what he is trying to accomplish is being able to fine tune the water for the pipe... having its dedicated waterline to the pipe it gets more pressure which will be good with the flow control valve if you have a factory and gets the water going into the pipe mist as it enters the exhaust instead of drip plus its cold water so it will have much better effect on the low end especially

I didn't know that the exhaust manifold only came with one fitting. Hey motoman did you just slide a new tube thru the old bilge line? 5200 the ends shut? I have a plastic line that I could use. I will also be running a flow control valve which will be set up right before the stinger/tailcone

How did you run your cooling lines motoman?

And did you tap your pump?

Run another tube so you can keep your siphon line. I got mine off mcmaster for like $6 (low quality aluminum 3/8" tube) Either way you will have to tap the pump for a second fitting, which is problematic because the fx1 pump doesn't have any meat for a second hole. I ended up trimming the pipe thread down to about a 1/4" long on the elbow so it wouldn't protrude into the pump and used some JB weld to help secure it.

For the second aluminum tube i drilled a 3/8" hole on the pump side. Then sharpened the edge of the tube to cut through the foam. I put the opposite end of the tube into the chuck of my drill and fed it through to the bulkhead. It's pretty easy to get a straight shot, just keep your eye looking down the tube and keep it straight. Then just spin the out of it while pressing it up against the bulkhead for a little while. Stick your hand on the bulkhead and feel for the hot spot. Mark it, drill it, and pull the tube through. Cut off excess and epoxy it in place.

i also ran a new line i just used 3/8 copper tubing for line.. i ran mine just above or just below original cooling line. taped pump on oposite side.. i agree its thin i threaded fitting in to pump them grinded it down with grinding bit flush with pump.

I would also question whether you need dual cooling. Unless your running a big motor, it really isn't necessary. I've run single cooling on my FX for 18 years with a freestyle ported 701 and never had an issue. I only went to dual cooling when I installed a ss865.

i think for now, i will stick with the single line in and just run a T to split the water to the 2 lower exhaust manifold fittings. i dont want to mess with tapping a small pump that i will be replacing in the future.
