Interesting.
The Yanks got some different ideas.
I noticed the car does not have an intercooler.
So the way I see it, by installing the turbo under the car on the outside, (Cold) air can easily get to the turbo.
Also since the turbo is exposed to the outside air, the turbo housing can act as the intercooler.
Only down fall is if the car is too low, something might hit the turbo and the pod will suck in a lot of dirt and shit from the ground.
