So the octane pipe had a fwd facing manifold like the super jet type 8? Someone was looking at those manifolds and had an idea that made bank

I make no claims to know anything, but these are pictures that have been posted on here in the past.

Makes a lot of sense to me that somebody would start prototyping by cutting up an existing pipe...but relatively subtle detail changes can make a big difference.

To answer the threads original question, then get back to the stuff I love.
I started this entire engine thing because sitting with some friends, a few drinks too many maybe, I was talking about DASA not making their cast cylinder anymore and how it compared to billet material in water cooled engines. One of my buddies (can't remember who) asked if I was so smart why don't I just build my own? So like any dumbass, I thought, why not? Casting a two stroke cylinder is not easy. Yes there are quite a few foundry's through out country and world but only a couple that can do it right (if you don't believe me go do it yourself, and if you think you can go oversees to where english is a second language, good luck) especially if you have inner walls (an entire different level). My goal was never to just make average to just sell, and not-on a budget--- but only one goal-- best performing engine period. After a ton of time testing and comparing at the highest level I now believe that this is true. But all this came with a price. I was usually a one man show, I did have some shop helpers and things moved better but usually just me. I love building special engines but not regular ones and I hate the business aspect of this and I started to not like jetskiing. So after a couple of little hiccups I made my decision to exit TPE, my baby. I had to figure every part to the engine out one step at a time, I didn't call a competitor to ask how to make it work. I did it all by myself. Now when it came time to tuning what I conceived that's where Phil Clemmons came in. He put the first 10mm non pv engine into his boat and flipped it on Superbowl Sunday while it was snowing. From there he would get the first engines, come up with a tuning spec and off we were. Those were the best days. Working with Phil was the best part of this. Since that time I have made good friends with a few others. Paul Lehr, his boats always showed what was possible in surf tuning and Brian Sizemore of Torrent pumps. I have learned so much from those two. With these three I know how the performance and reliability sizes up and I am pleased and confident with both aspects.
As I said before, DASA is the right and best company to carry on with what I started, they did the cast cylinder that raised the game for what we do now, its all come home.
Ask questions if you like.
So now I will be building only special versions of these engines and other engines along with rebuilds but on a time table I can live with. With what I've learned with these engines I can push so much more out. There was always some left in them and now I want to pull it out. I've had other ideas on parts but no time to work them out, soon I will.

So when it comes to pipe, each has its own characteristic. This sport does not do it correctly. The correct way is to design engine performance parameters then make a pipe that works to that parameter the best. In jetskiing we build a motor then bolt on a pipe and hope it works. In the racing days the pipes were modded (not that you would notice the changes to the naked eye). The type 9 was the best at the end but the R&D was that good also. The thing about pipes is, if you miss the mark by just a tad, the pipe will not work as well, so just cutting and trying is a pain. In the early days I remember going to the water with a guy who would try two dozen headers and two dozen convergence and more stingers. The dyno would show one thing but water testing would show different. It was a matter of getting a group of dyno variations then going to the water to really see what was what. It was fun but a ton of work.

First off, to me the most special part of you creating TPE was the friendships you created out of it. I truely traesure and I’m proud of the part I help play in your development of this cyl design. Like I told you in the very beginning, you have created one of the biggest milestones this sport has seen since its inception with TPE. This cyl has only just begun to tap its true potential. Its moving on to Dan & Kyle at DASA, will cement its true place in the history of this sport. Please dont carry any regrets, because of your vision, this sport will move to higher levels of performance sport.
Very few get a chance to accomplish something like this. Kudos to you and lets see where this next chapter takes us!

Ski Ya, Paul

Blah blah blah , waa waa waa , sniffle sniffle sniffle ...... now get back to designing and building that part you promised me. Or get your new buddies at DASA on the project. Stop playing with your cats and get on it.
