WET PIPE / DRY PIPE ???

[bigalsnow]

What are the advantages/disadvantages of each, what type of ski benefits from the different pipes? Superjet application.

Wet pipe will have better bottom end response. Dry Pipe will have better mod to too performance. Downside to dry pipe is maintenance. The couplers and orings will blow out. You can do some work to the Lord mount flanges on the dry pipe so that there is no side tension on the mounts (slot the mounting holes) and this will take pressure off the coupler.

Dry pipe is also heavier than a wet since it's essentially two pipes in one. That weight on the left side may benefit handling/balance on some skis. You put a wet pipe on some superjets and they get the gangsta lean to the right from less weight on the exhaust.

I have the Speedwerx race version dry pipe...currently on the shelf due to repair needs...but I totally loved the power of it. I currently am running a B-pipe and it's good too, but to me it is not quite as potent as the Speedwerx was. The B-pipe does have that immediate power response where the dry pipe didn't, it always needed a little higher RPM to really take hold and perform. But I really loved where the power came on with it, just before getting up to the wave I would open it up, by the time I reached the wave top it was sailin'! The B does well for allowing you to get closer to the wave and then gun it but it still just doesn't seem to have that over all wallop the Speedwerx has. It could be just me, but I really miss my dry pipe. They definitely do need to be monitored and installed with a lot attention to detail though, do everything you can to relieve any kind of pressure points so the pipe can just be placed in position and locked down, if you have to force lord mounts into place, or push the pipe or hoses around to get things to line up then you need address those issues before you run it. I tore the o-ringed spigot at the front of the pipe clean off of my Speedwerx because of this very reason. It had sideways pressure I was not familiar with, the exhaust hose was putting pressure on it too at the waterbox. If you have to cut the exit tube off and re-weld it in a much more friendly angle and alignment wit the waterbox hose then do it. It will probably be the difference between a destroyed pipe and a long term reliable and awesome performing pipe.

This is what happens when you are not familiar with stressed mounts and hoses...at least it happens to me lol

Sorry to hear about your damaged speedwerx pipe. They always get praise as being one of the best made during the 701 dominance era in racing.

I've got an r&d dry pipe I'm gonna try out on my ski this year, we'll see how that goes.

Even a bpipe can give you issues if youre not careful with the fitment as I learned today. Installed a new 4 ply coupler and thought everything was good and yet the ski ran really bad. Turns out the water box hose was pulling on the chamber a bit and after a few hours of tinkering finally got it to hold. Ran waaaay better. Never had encountered exhaust leak on my ski but have seen them on other skis. The problem is almost always where you haven't looked

The R&D pipe is a great pipe, until it cracks.

That's what I've heard. It's strickly a lake pipe, no ocean riding or anything similar. Gonna try it without a Lord mount. Using an aluminum tube and short couplers for waterbox connection. And probably a foam block/support mount in that area. Worm gear clamps at the manifold coupler. We'll see how it goes.

I have an about 6lb weight on the left side of my superjet. It bolts down by using the 2 inside bolts of the left side motor mounts. The lean wasn't just when floating. It actually kept me from turning left correctly. The weight dramatically improved handling for me.

If you want a bullet proof pipe that you bolt in and don't touch for years, get a Bpipe. They are pretty much bullet proof, provide good low playful power and basically no maintenance. If you like to tune, fiddle with poop and miss days on the lake due to blown couplers and orings...

I agree, but you can say that about anything non stock really. Change one thing and you're fiddling with it more. Want the most out of it, more tinkering.
