Cheap Carbon B-pipe

[js/sj]

I was wondering if this was worth getting. ( http://www.watercraftfactory.com/html/products2.html#carbonpipe ) The wamiltons one is like $1399 complete but watercraft factory has the Carbon chamber for like $400. It is the Mod chamber though not the limited, so i was wondering if its that big of a deal? I might just buy the head pipe and This carbon chamber and the manifold and only pay about $100 more than a limited stock pipe. Any thoughts?

Why? That's my thought. Not trying to be a jerk, either.

I don't see any benefit on the carbon chamber (unless you are some lbs counter, trying to hack every bit of weight possible) and it also depends on what setup you are running. I believe mod is better for bigger bore/ported motors.

seen those chambers break too..... never seen an fp one break

just buy a regular chamber..... carbon will just look cool

We tested 3 off these pipes 2011. They dont break!!!

But fit only in our TriXstar hull.

So they're bigger than a standard FPP chamber? What drove that design decision?

Must've heard "size matters" too much while dating.

So you had to buy more aftermarket parts when you realized that the chamber doesn't fit. :wiggle:

I would the think the very old original B pipe design was limited by space...I mean they for sure took every friggin centimeter they could..but they were still limited...

Matt,you dont must love me or my products..... That do many others.
The FP chamber is a agreement to the small place bitwen hull and gastank, or you have seen a dirtbikechamber looks like b-pipechamber. Good friend of me is a good dirtbike enginebuilder and he helped me to redesign the chamber.

And it works......

Cool, I was just curious why you made it bigger. Figured there was a good reason.
Does it work noticeably better than a standard FPP chamber?

EDIT: Me asking questions doesn't mean I don't like you or your products.
I don't think your dirt bike chamber comparison is particularly meaningful. Bikes have a transmission and clutch. Pipes for bikes are designed to develop peak power at one particular RPM spot.
Ski pipes (wet pipes in particular) are designed to give power on a very broad RPM range.

Last year we tested a prototyp with 12mm dasa. More bottom end torqe. Mid and high rpm neary same. First chamber build top/ bottompart and glued........ Breaks after 3 testdrivedays. New chambers build as 1 part without glueing.

But no chance to build it into pre08 Sj.


Thanks, Andy

Looks like it's a high quality part. Nice job.

 

[Kawastyler]

Hope i can 1:1 compare it on a small no pv engine next year.

Hallo Matt, you are rigth........ Increasing the angle of cone/contercone gives you more peakpower on smaler RPM range. But the chamber ist designed for PV engines, they have wider powerband if PVs working.
We have to compare it 1:1 in 1 pv and nonPV ski next spring.

Here some pics of my ski i sold 3weeks ago. Engine is 700 62t ported with Matts foruminstructions. Oem 38s, milled stockhead (13,5 bar/100oktanfuel), stockpump with 13/17, stock ignition , b-pipe with my carbonchamber. First thy to flip a ski in flatwater. No setup wake........ Pull the trim, prejump und then open throttle. I think it looks like powerfull engine????
