im almost to mindboggled to type after looking at those photos....
ive never seen or heard of anything like that. as far as concerns, the only thing i saw that i just absolutely dont like is that the air intake for the turbos is not only under the car, where i would think breathing would be more limited, but is right by the back tires and right where all kinds of road debris will hit it as it flys off the tires. of course, i live on a dirt / gravel road, so this is a BIG concern to me. i would imagine one would be cleaning those cone filters quite frequently, and i could see a nicely sized rock flung up at the right speed punching a hole in the filter and all kinds of garbage going down the intake...
on another note, i simply have the question of why?
why is that system designed like that? is that the only way to fit a twin turbo system on an s197 or is there supposed to be more efficiency there, or is it a "sleeper" turbo system so no one sees it, or what?
i wouldnt buy it do to the above concerns....and it looks like a plumbing nightmare.

then if they are not having problems sucking up water or trash, then I might consider it. as far as no heat soak, yeah, that would be a benefit, but what about the negative air pressure that is under a car as it is moving at speed? wonder how that would affect air flow into the intake? especially on a lowered car
the only real benefit i see is you could make it a sleeper. boy that would sure be a surprise to someone who was acting a fool.....
