-to freek’s comment, i hardly call the 997 slow, i dont care which one of your friends drove it…maybe he drove a NA 997 911 which arent impressive as far as speed goes, but still unbelievable to drive
Maybe I’m reading this wrong but it sounds like your saying this car has two turbos. The article says it has only one…it just “allows the angle of the compressor’s turbine blades to continually adjust.”
I haven’t tuned a turbo like that before, but I’ve worked with a VNT (variable nozzle) turbo off a truck that was put on a car and it weighed about 80 pounds. It does spool up quickly, but the flow with the nozzle “squinting” obviously isn’t anywhere near what it is with the nozzle expanded. While you’re building pressure more quickly you aren’t getting a massive gain in low end flow. This design is fine on trucks but doesn’t make much sense to me on a car. With more time I can see it being improved upon so we’ll see what happens.
I’m curious to see if the variable wheel angle design performs better.

Seriously though, I still want to know the cost of these bad boys.
It seems the money is not well spent.
I bet they could have put CF wheels on the car for less money.
