50cc, 20hp, 15psi

I'm more interested in real-world application. A motor sitting on a test stand just doesn't do it for me.

I agree on the test stand bit, but he has to be going someplace with it. No need to make 20hp if you're going to put it to the ground.

No motor... but this takes solid brass b***s...

Not sure how compelling a small motor on a stationary stand is to me.

Well, it's quite and interesting design, built from scratch. The cylinder and head are custom designed (exhaust port is 180* wide!), the pipe is matched to suit - and this engine is actually one of two. The PIP is intended to set record for HP/CC. The Brute Force engine was designed around the SC, but he was having problems savaging enough exhaust. So, two posts ago, he decided to marry the two and put the SC on the NA engine.

The guy came to the US several years ago to compete in the Boneville Salt Flats, but got rained out. He went home and wanted to build the most powerful 2t in the world.

Just for your entertainment! Here he is doing over 80mph on his "bicycle" lol:

He has a brake on it, but he said it seems to be not working so he was getting an useful HP reading. 20hp on a 50cc should be compelling.

Actually, he was just applying the eddy current brake to make sure the engine could take loading.

More "exciting content from this guy:



Again, go back and check out the story from the beginning. He went from using CG engines, to casting his own cylinders, to CNC machining them.

...gears are nice.

So is ~14,000rpm.
