Have never doubt you
Congrats!

 

Wow, That thing sounds great! Congratulations on getting it running! Whats the next step?

 

Fantastic Work How long before you get to eat some piston powered boats

 

This creation is beautiful and can make a grown man cry...congratulations!!!

 

Congrats man. Things are starting to move ahead. Good luck with everything. Hope u can meet ur goals and shock the world with your motor design.

 

thanks for all the support from everyone


well... the next step is get the turbos and have the exhaust pieces made to mount them.
I'm thinking two 115 mm to start with.

 

Tyson... congrats! It was great meeting you and your GF at Sevenstock. Myself (yellow FD) and the rest of the Arizona crew REALLY enjoyed helping you unload that beast the night before and hanging with you at the pool POST event! You're a class act my friend, and I give you MAJOR Kudos for following your dream and sticking with it when others would have thrown in the towl. It's an inspiring piece of engineering work!

Happy Thanksgiving. Here's to the future success of your design!

 

Holy ****!!! The exhaust pulse alone will move the boat forward!! Well done, have been waiting for this.

2 turbos? Surely 3 would be the most sensible option seen as you you have 3 banks of 4 rotors?

 

there are only two holes in the back of our boats for exhaust so I made this engine have only two exhaust pipes comming out of it.. the center row of rotors have two that the exhaust go the left pipe and two that go out to the right pipe

 

Congrats on the startup, that is an awesome accomplishment. I don't know if its just the soundstream but it sounds like a volkswagen bug race engine that my buddy runs. I am still a little skeptical on how long it will last but I wish you the best and hope it lasts a long long time.

 

Holy
****
Also that's a mean-sounding engine, crazy job wow

 

another video.. this time I closed the cover on the gopro so the mic would not distort as much but being a sealed water tight unit it still cuts out some of the high frequency but this is a little closer to what it sounds like.

P u r e a w e s o m e n e s s!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Congratulations bro, 2 thumbs up! Now write a letter and send a video to Mazda and school them!

 

considering alot of this IS mazda technology, yeah.

 

bigyellowcat, this is UNBELIEVABLE. Ive been following this thread since it started and i cant believe its finally running. Many people didnt believe youd succeed, and you proved all of them wrong, Congrats!!

 

I didn't even notice that. There's so much going on with your engine I can't actually tell what is what!!

I'm going to plug my head phones in now to listen to the engine as the iPhone speakers don't do it justice.

 

lets see how it runs!!! thats the real deal

 

Holy crap. That is the meanest sounding tickOver ever.

At what rpm was that at?

 

most of that time it was idle at 7-800 rpm
when I let the idle get low at that one point to see how low it would idle it was at 300 rpm
when I rev it in the other video it was going to around 7k. it speeds up alot faster then a normal rotary. there are alot more power pulses per crank revolution.

 

That is brilliant, I bet the equivalent petrol piston engine couldn't idle that low?!

Keep us updated.

What are you using to control the engine ecu wise? How many injectors are you using? Or am I being thick and you have managed to squeeze some carbs in there somewhere?

 

Any plans to strap it to the Dyno any time soon?

 

thats really a great job. get a film crew with some hd equip so we can hear the actual sound/tone of this worlds first accomplishment.

 

Is anyone going to the PRI show in Orlando? I am cleaning up the engine to take it there and put it on display. Make some piston guys scratch there heads..
