When is the sport going to move to snowmobile cases, cranks and custom cylinders with jetski specific porting? Loads more R&D, a/m parts, testing, pipes, FI, etc etc

Storbeck ---that third pipe with the gp800 block is my pipe and block. Where did you get that pick, and I finished the pipe. It's now in my storage unit buried somewhere.


Quinc---- jetski engines are very specific in function. Every time I see a "snowmobile" engine end up in a ski, it always runs "awesome" when told by the builder. Then in real life its average at best. Jetski's have a specific power band that snowmobiles don't have to have. If you do put time and money into it then who's going to do it? There are only a couple of people left that really understand how and why with jetski stuff.
Damn, I keep seeing guys messing with waterboxes, really? If you knew what your doing I'd focus on pipes, and a dyno only gets you so far, it's water testing that is the final answer and if you don't have a really good rider to give feedback (and that's a special rider) then your just going down into a rabbit hole. Why spend the money and time to r&d stuff only to have it copied by some guy with little knowledge and a cnc. OH, and the TPE / DASA cylinder is just what your talking about, it is custom and the design is that good for what we do, snowmobile engines run different. I just had to make it fit on yama case so it would fit in a hull. Yes, I could have built an entire engine that makes more power but it would be larger in size, heavier, require a special ex. mani. and when you ride it in the surf think about that extra weight on your motor mounts when your boat makes a crash landing.
The PFP pipe was the first pipe designed for this particular segment of watercraft and look now, water injection, carbon/glass versions. Totally changed the tuning design. The TNT pipe works amazing with a TPE/DASA 964 and when tuned correctly its more power than 95% of people can ride in the surf, even for some pro's. There is so much tuning to be done with temp control in pipes, look at Paul Lehr's boat, That's tunning to a different level. People want special parts made when they can't even tune what they have. If I were the average guy on this forum I'd want to learn how this stuff really works so I can tune it better. Pipe cutting always scares me because guys add length, change an angle, change a volume, change a heat zone, and a two stroke program won't/doesn't give the correct answer. Pipe knowledge and water testing do.

I have ideas to mod pipes but those pieces will only go to custom boats.

Just to give an idea of Paul's tuning: I rode his first 964. He also set up my 1105. A year goes by and I hop on his ski because he wants my "completely amateur at best" (quoting myself) opinion and it was so much more power this time from what I was expecting that when I jokingly turned to spray Harrison with the pump spray as we were riding out from shore, the ski shot out of my hands completely and leapt about 10 feet away from me because I wasnt suspecting the power difference. It was insane power just from tuning differences.

Tuning on a ski is like gearing on a car. You can have the nastiest motor in the world, if it isn’t geared right, you won’t get the power to the ground. There really isn’t a lot of magic in 2 stroke motors, the magic is in the set up.

I say nay to that name. It implies that they had somthing to do with the original product. In my opinion They have to earn that title. If they make new innovations or change somthing that Erik didn’t already pour his soul into then good on them!

Just my opinion.

I was mainly reading about the pipe discussion... seems like a lot of informed people here though, how early is this pipe?

I'm sure that's true, I know it sounds crazy but my ultimate goal is to build a powervalve twin for speed and I already have a few traditional superjet pipes from back in the day I'd like to use

I'm doing it with a kawi dasa 920cc built/ported by Eric, in a bullett gen2 x2
