How can i get the most Braaap?

[Nerd 10]

I have a pjs half pipe right now and in need of a water box! I was wondering will my pjs half pipe give me braap like a full pipe with a waterbox? I want a pretty loud 550 but don't know what waterbox to get for that... help!

Rear exhaust sounds really nice on a stack box.

Get a west coast. They're the LOUDEST. mariners and PJs water boxes sound cool, but west coast is the loudest. Half pipes are better than full pipes in bottom end. Top end too I believe. You want brap? A 550 doesn't have real brap till you do a lot to it. Want a list? Ask for one and I'll provide.

I have a WestCoast Aluminum water box out of my old 550sx I will give you cheap. It was loud enough that I wrapped in dynamat to try and quiet it down..

everyone at the lake or river always appreciates a nice loud ski, helps them remember to suggest to ban them at the next town meeting.

Kwakhead yeah man a list would be nice!

Here goes. Skat 16 impeller, group k pump blueprinting, group k nozzle boring, mill head but do not cut the size of your squish zone, copper head and base gaskets, scoop grate, ride plate with skeggs preferably, quick steer, stick with the half pipe, sbn44 or dual sbn38's, port the intake and exhaust Mani's, don't forget to chamfer. Widen intake port around 2mm, lower intake port 1.5mm, make the little point at the top of the cylinder a little bit smaller in diameter, for exhaust ports raise them 2mm, widen 2mm. Don't forget to chamfer, chamfer, chamfer! Or you can catch a ring! I like the aluminum driveshafts, but aluminum charging flywheels are where its at! MAKE SURE YOUR STATOR WORKS PERFECTLY! Dyna coil ignition coils help to obtain stronger spark, I have one for sale, get some PULSE PLUGS, west coast gas tank. Can't remember much else, but that has always been the standard outfit for all my 550's

Put a 750sp in that ski!

Put a 750sp in that ski!

working out the ebox location, configuring the pump to the 750, and what pipe setup to use are a huge pain in every conversion. Its never bolt in and go. Expect some minor fabrication, and buying some custom parts

Would be nice but not a this moment! just bought the ski and want to enjoy it with the stock motor and bolt ons!

When I upgrade my SJ, I'm going to put its old 650 motor in my JS550 using this conversion kit. http://www.rhaasproducts.com/ProductDetails.asp?ProductCode=550-701conv

Mount a 3 inch pipe on top of your pole and connect the exhaust to it. A small megaphone attached near the pad should satisfy your need for noise! If not then delete the muffler and try again.
