I need info on pipes! Please

[flyinb501]

I've done my fair share of searching, but I'm not quite figuring it out. My buddy just got a factory b pipe on his new superjet, and it rips. Now I need to find myself one for my own sj. I think I'll try and get a used one.

Anyway, what would be best for freestyle? Also, what is the difference between a dry pipe, and the factory b pipe? The b pipe seems to be more popular, but I see lots of good deals on dry pipes in the classifieds. Any difference in gains? What's the setbacks of a dry pipe? I want to keep my ski as reliable as possible.

Lets figure out a time for us to ride, then you can try his B pipe vs. my dry...

i've got one of each in each ski, a B wet pipe in one ski and a Type 4 dry pipe in another... they both rock for sure. My dry pipe ski has much more mid range accelleration and top end.

dislaimer: the skis are not entirely set up the same though... so it's likely not a fair comparison

B pipe - freeride ported 701 61x cylinder 35cc domes oem 38mm carbs

dry pipe - race ported 701 62t cylinder 37cc domes 44mm mikuni red topped carbs (not using water injection either)

So is one louder than the other? What about the cooling? Is there something I need to add with the dry pipe?

Jason, yeah that sounds good. You should throw that life vest in your car when you go to work. I could stop by your work at some point this week, and pick it up.

AHHH...sorry I didnt check this after posting last night. I will throw it in my truck tomorrow, promise. The dry pipe seems louder to me, but sounds very good. Cooling setup is very similar, either way you'll want to run dual cooling as long as you're in there the only problem with the dry pipe is you want to run an aftermarket head for the extra support (Im also not sure if all the bolts lign up on the factory head)

 

[flyinb501]

So how much does the dual cooling cost, and how tough is it to install? It is necessary to have an aftermarket head with the dry pipe? I don't think I want to mess with that.

 

[yamanube]

You need to get your pump tapped and a 90* fitting put in, after that its cake. Ill help you put it together, really its like an extra 5 minutes if you are putting a new pipe in anyways.

 

[flyinb501]

So is their a kit you just buy for the dual cooling?

 

[yamanube]

Nope, just drill and tap the bung on your pump (already cast into the pump and perfect place for a second cooling fitting) put a 90* fittin there, run that into the tube where the stock bilge used to be and into your manifold. Materials required are one 90 fitting, few feet of cooling line and a few hose clamps.

 

[flyinb501]

Right on. Sounds easy enough.
