Water routing ?

the hull (98 sj) im putting together came with 3 pissers on it. Id like to use all three. Ive got a riva freeride pipe. Im thinking of adding a tee between the pump and manifold and running water line directly to the pipe. Then run both bypasses off the head to 2 of the pissers and 3rd pisser off of the pipe. Is there a downside to this? Could really cold water damage the pipe? The hull was a backup race hull with sponsons and hull extentions. So im plannin lots of WOT runs.

What engine setup will you be running?

I assume you have dual cooling from the pump?

If you wanna run separate lines for engine and pump, that's fine. I don't recomend running more lines off head than what goes into the manifold though so pressure stays up. If you have one line in mani, tee the two on the head together or restrict the pissers.

I like running separate cooling lines for engine and exhaust. Having cold water in the head pipe allows you to run the pipe a bit more dry. Once I started drying out my pipe the throttle response really came to life.

Bottom line, pay attention to the water temp leaving pissers. You should always be able to hold your hand in the water coming out.

61x/61x. Stock bore. Ada girdled head. W/33 cc domes. Hoping compression will be around 180 To still run pump gas. Pump only has one tap for cooling. But the hull does have a pass through currently plugged. Didnt think about the water pressure. So if i used ristrictors (like whats used on b pipes?) then one into mani and 2 out of head could work?

I recomend utilizing the second line in your hull. It's pretty easy to Tapp for a second cooling line.

Despite what many will say, 180 is a tad high for running wot for long periods of time. I highly suggest tuning with a tachometer for peak rpm and add an 1/8 of a turn at the least.

As for restrictors, anything can be used... I personally like the tapered cap on silicone cut down to the desired size. Easy to obtain and you can keep a few handy for water temp changes. Just shove it in the hose right before the pisser. You don't want to use pop off valves like used on a b pipe.

Personally I would do one in the exhaust mani and tee the two on the head and dump that over. Keeps 1 in 1 out. Then use the second line for the exhaust. cap off the 3rd pisser for looks. Just my 2 cents.

180 compression is bad for wot? Or its bad for wot with pump gas? I think comp will be closer to 170. 33cc is 200 @ sea level. Im @ 7000-7500ft

Water routing is still basically the same. Just your in and out of the pipe is different. But look as the Head Pipe of the B Pipe as the entire section of the chamber of the B Pipe........ With the Dry, your not worried about how much water your adding or taking away. Your just cooling the pipe. Now, you can add ECWI to the dry pipe manifold to add water to change the tuning on the bottom!
