Actually the application of a rear mounted turbo has been around for years.
Hellion and STS (Squire Turbo Systems) both make rear mount systems for cars like the Camaro, Mustang, Corvette and Mopar V8 applications.https://www.google.com/search?q=sts+rea ... CGQQsAQIPwhttp://www.americanmuscle.com/hellion-t ... &GID=42611
Most V8 cars and V6 SUV's have tiny engine compartments that already run hot. Adding a Turbo to the mix creates problems in how to best dissipate the heat while still maintaining respectable power.
Anyways, the kits that are available are designed to fit under the car. Not like this one-off. That being said Escape94, In this instance I agree. Just because you can doesn't mean you should. To each their own!
I think it would be pretty respectable if they could just get it tucked under so that it doesn't hit every rock and pebble on the road. Turbo lag I'm sure is present given the size of the turbo they used and the piping to the application it's being used for.
Do you have any info on the year escape or what tag line the images use? I'm sure there is a dyno somewhere if this a legitimate vehicle.
