really?? you think 10k+ ? I just don't see how they would think charging that much would bring in enough people to buy it... It's very neat and all but it isn't proven on everyday cars yet and I just don't think charging that much would yield them good results. Of course just my opinion

I love it when old technologies resurface in new ways.

Multistage supercharging was a staple of aircraft engine design from the late thirties onward. It was done mechanically at the time, of course, with basically a transmission on the drive side of the blower.

it does beg the question of why you'd need to do this. Since it's fairly easy to design a single stage compressor to function over a broad range of RPMs when air density is relatively constant, I'd wonder why you'd need the complexity of a multistage setup like this.

For extreme builds? Ability to run a huge HU without lag. I.e. V3 bottom end with YSI top end?

If that's the case, very cool.

I'd be thinking if you're going that extreme, maximizing torque at 1500 rpm probably isn't your biggest concern. There's already a bit of an answer to this in the form of varying the step-up ratio in the HU. combine that with modern impeller designs and you can get that quick response without sacrificing top end. You're right though, that'd have to be the intended market.

It still just feels like a solution in search of a problem and given that it isn't likely to be too cheap, nor easy to tune beyond the factory setups and adds a huge amount of complexity, potential reliability issues and likely weight up front, I dunno.

I can see a need potentially in the towing market for something like this. Low boost for light loads with ramp up for heavy haul. That does not seem to be how its being marketed from the video though. The solution to that already exists too though, called a turbo.
