My understanding / opinion is that it is the best tuned supercharger on the road. From the dyno, testimonials, and seeing it up close, and seeing it run you really have to appreciate the engineering and engine tuning that went into this thing.
It is really a work of art until...
You put that damn thing on an NSX engine. Then it looks like someone was trying to play that game "mousetrap" with an NSX engine. I keep wondering where to put that little "pinball" to start the game.
I personally just can't stand that type of in your face for all to see supercharger. The BBSC wins the "packaging" game for the supers with the CTSC barely getting a passing grade IMO. The Gruppe M unit just looks like some kind of Mad Maxx tribute IMO but in no worse then some of the in your face, is that the turbo or the engine turbo chargers.
If asthetics do not matter or you like the looks - it definately should be on your "shopping" list for well engineered, well supported, reliable, streetable FI.
