imagine a four-liter normally aspirated V8 that makes 1,000 horsepower and gets good mileage? According to the Italian NEVIS (New Exhaust Valve & Intake System) Engine Company LTD., this sort of engine will soon be a reality. Complete with innovations such as donut-shaped pistons, the ability to run on any fuel you like (gasoline, diesel, bio, meth, hydrogen) and the Trekkie sounding Bortone Cycle, NEVIS's product should extend the life of the ICE for many decades to come. The killer app is the already mentioned Bortone Cycle that allows a power stroke for every 120 degrees of crankshaft rotation. Which means that for every power stroke your dirty old four-stroke pulls off, the NEVIS engine is performing six. Which we must say is pretty intriguing. Especially the part about the variable compression ratio going as high as 38:1. – Jonny Lieberman

It's a lot of reading, and I'm trying to get some work in today as well lol.
Here's what I understand so far:

There is a video, go to the main page, but I got tired of waiting for it to queue up.
Interesting concept, if it works, easily, and can last for as long as current engines do.

Well, if they make an 8 cyl. version it definately will not be a "V" engine.
What was impressive? Lots.. Not done reading but I do worry about those journals and wear, but it has to be better than the stupid apex seals on a rotary engine. 2 cyl, 1000cc making 250 HP, that sounds good too.

After looking at more material, I still have concerns about wear. The vibrations are big and the way the pistons travel relies heavily on bearring journals staying tight. I wonder just how long it will last? The performance estimates are fantastic but they are just estimates. They have a working prototype, why do they not provide dyno numbers? I am guessing that they did not hit their goals with the prototype.
I'll keep an eye for progress but I won't hold my breath.
