Freestyle new rrp carbon pipe

I think it is a Motoine Kawasaki pipe, but I can't seem to find any info on it. I found this one as well.

Yep had them bring it to worlds for me. Anyone who wants one. Hiro can translate to get anything here.

I paid $960 with Hiro taking what ever cut he did for making it happen.

If anyone wants any of this odd ball over seas stuff. Hiro will get it for you and shipped here.
 
The people who are really serious about creating a completely new exhaust system should spend the extra time/money to put some numbers into a two stroke expansion chamber design software just to get a reference in relation to existing designs. Without any kind of R&D it's a shot in the dark based on somebody elses design (ie copying).
Building one pipe, testing, revising and ending up with better performance than the previous model and ending with that is not R&D, that is trial and error.

This is the exact plan. Using a program to make the optimum chamber for the TPE 1105 I will be running. With the help of Dr. Smoke screen, some advanced algebra and trigonometry and a chamber program we are going to try to make a chamber that will not only work, but fit the hull. I have been told the WDK chamber is one of the best for larger motors due to its chamber size/ design. Now to be able to fit a chamber of that volume, and still have all the proper deflection points and angles where they need to be in an up and over design with a type 9 manifold is going to be the real science of it all.

Then seeing the Japanese use a carbon r&d version of the wet pipe it contradicts everything I just mentioned about larger expansion chambers for the big cc modern engines. Maybe I'll build both and see what happens.
 
No back to back test yet?? Really curious.

I'll make a guess at what the back to back tests will show:
Original PFP dry chamber will hit like crazy mid to upper rpm power. RRP carbon wet chamber should be noticeably better low to mid range and possibly go flat up top. That's just my guess. I'm really curious to see what the outcome is.

Brian, so it is gonna be the best of both worlds.... More bottom/mid and a couple of pounds less (about 15 including water savings)....

I had ordered a PFP from Thrust but deciding to change for a RRP.

That's just my guess, I have not tested them myself. Just going by what I have heard about water injection on a pfp dry pipe. It does improve low and mid range. Looking at the water routing instructions it looks as if this pipe runs wet the whole time. If you look at what the water in the pipe does, it tricks the motor into thinking the chamber is different inside than it actually is, thus improving performance and response at lower rpms. Running a dry pipe will make more power at higher rpms, ask anyone who ran a power factor, they make power at a different rpm range than a b pipe. I'm fascinated by mechanical water injection that can cut or reduce flow from a pre defined rpm range to redline. That in itself would be the best of both worlds. Like having b pipe off idle snap and power factor mid and top pull. Not rocket science, just a matter of reading and talking to people who know more than I do. There are a lot of knowledgeable people on here. Hopefully someone chimes in.

Again I'm just going off basics that have already been proven. Nobody will know until someone tests these back to back. Who knows it may make such a difference that carb tweaking, pump and nozzle tuning may be necessary. So just swapping pipes around might not be an easy and accurate test. If it changes that much the whole package may have to change with it, if that's the case it may be a good thing ;)

If you guys get a spare moment give Taylor Cutis a call. He's been running one for a year. Mostly in a flatwater setup, but it's now in his surf ski.

He can can help you understand more about its overall differences between this and the PFP. Awesome guy to talk to, hit him up.
 
How does the half dry work? The wetjet pipe (made by westcoast) is supposedly a half dry, the manifold and first part of the "headpipe"is dry, and the second part of the chamber is wet. Would this be a similar setup? Plus the wetjet mani is equal length, it's a really nice piece that I think would work well for a custom pipe.

...chaos? Its Fair!

I have this setup in my fx1. I need to adjust the water flow. Right now the bottom end is a bit laggy but once the engine gets on the pipe. It pulls like a sob. Mid tot op range is phenomenal.
