That is a good point Woody. If this guy really has had the transmission, rear axle, and driveshaft upgraded by Carlsson then I am intrigued as to what 'upgrades' were actually done to them, and even what HP he is pushing to the wheels. It doesn't seem like he has EXTENSIVE engine modifications, only simple ones (i.e. CAI, race coils, race ignition, etc).

I would be willing to wager an upgraded transmission by Carlsson like this would run at least $5k.
