I want to know more. :) Interesting concept, note that they removed seat and associated bracing. :rolleyes: Just because someone knows how to weld alum. doesn't mean they should... ;)

Unfortunately, the pic did not have detailed info with it.
But this engine, from what I can find produces up to 195h.p. normally aspirated. So with the turbo, depending on the boost pressure, maybe 300h.p. Quite a lot for an aluminum boat better suited to a 9h.p. outboard...thus making him a contender in this thread. šŸ™„

From the amount of work I've done on alumimum YACHTS with maybe a 200hp diesel mounted to 3/8" stringers pushing 50'+ of vessel, I can tell you with certainty that engine would tear out the "mounts" and jet drive fairly quickly. I just wanted to see the video... :D

Yes, I was gonna post a video up like that, but didn't get around to it.

Years back I had a video of a guy that put a rotary in a john boat style boat. He didn't die and the thing was a straight line rocket. So the V-tec photos is not really that new. His rotary boat also had half the displacement but the equivalent power with no turbos attached like the V-tec. It was red neck built and bare bones. I had the video on my computer for years, but that computer is long gone. Back in the Windows 3.1 or Windows 95 years!

Here are two boats that are around the displacement of the V-tec 4 cylinder posted earlier. The first is actually a 1.3 liter engine which is 700 to 1,100 cc's less than the V-tech. And the second video is about the same engine size as the V-tec. Both are good, but you will want to watch the second one for sure. The second video states 1,300 horsepower and that is probably correct with Methanol. With normal fuel systems, it would output somewhere around 1,000 horsepower.

There are a lot of V8 guys in this forum, but there is no piston engine that can output the same amount of power as a rotary engine with equivalent displacement size and equivalent external accessories. I have a lifetime experience building them and many rotaries here in the shop along with piston engines. My first engine I built was at 13 years old for my first car and was the same engine in the first boat below. The only difference was that mine didn't have the turbo on it. Nevertheless it shock the third floor of the house when I fired it up in our detached garage with open pipes going into a megaphone tip that was about 5-6 inches in diameter. You could hardly drive it on the street because it was bridge ported. Bridge porting creates the brap, brap, brap idle that you hear in the first video. It runs like a two stroke, all or nothing. Mine bucked around loping in neighborhoods at 30mph and whipped your head back and forth. It was not a vehicle to take a date on that's for sure.

Boat 1 - Probably around 500 hp depending on whether it's a single or twin turbo. It appears to be a single turbo based on how it revved. Notice the accusump or dry sump oiling system. This is probably due to the G's in the turns and to prevent oil starvation at the oil pickup in a normal oil pan.

Boat 2 states it's 1,300 horsepower and there are some serious G's in the turns here.

For some reason, I have never been able to wrap my head around how rotary engines work. Yes, I've seen the animated schematics.... But for some reason I have a mechanical mental "block." I just don't get it.

Instead of combustion occurring in one place on top of the piston, it "follows" the rotor around the axis. Since the rotor has three sides, three different cycles of combustion are always occurring simultaneously. As the rotor follows an "eliptical" path, the combustion "chambers" get larger and smaller corresponding to the strokes of a piston (intake, compression, power, exhaust). "Intake" is at the top in this gif...

Because we pistonheads think up and downstrokes. Heeharrhee.

The wankel is a brilliant design. Sadly, they could not get them to meet the imposing EPA standards and Mazda dropped them, iirc because of that.

Sorry about that. It happened to me too, but it was still worth sharing. That's some crazy balls that guy had. I reckon he may have died and that's why they didn't show it. Or, who knows why they didn't finish the video. Perhaps the battery went kaput. Nevertheless, the operator running that rig was highly skilled, or that was some great CGI created video in Aftereffects!

This definitely has potential of 250 to 275 HP. The intercooler is too small but the lack of any tubular framing would scare the sh!t out of me. I would love to see the video of this self destruction as the motor rips apart the boat the first time that hull slams against the water.
 
A. Shouldn't this disqualify him (among other things) for VP as lacking good judgement?
B. How much do you have to ingest to require hospitalization? (I'm not sure I really want to know the answer)
C. If Darwin had claimed him, it looks like it might have saved us all a lot of trouble...
D. When he debates Vance, any bets on if he calls J.D. "Wilbur"? šŸ˜‹

Here's how I know this is fake.... No doctor, hospital, or EMT would EVER be interviewed and divulge private patient information like that. Even before HIPAA. Not a chance.
