There is an AWD Dynopak dyno at a BMW shop about 5-10 miles east of Boulder ... kind of on the outskirts of Denver. I can't remember the name of it though, sorry. Don't know if it's much help or not [heh]. But there pricing is $175 to get the car hubs bolted up and the rest of the first hour you have your car on then it's like $75 per hour after that.
Hey you still want to meet up somewhere up there for the trip to SEMA? Just curious.
