I rode the snot out of the T660 on our test day on Pine Lake in northeast Minnesota. I grabbed one of the well-studded units and hit the plowed ice strip. The highest I saw flash was 109 mph, deep into the strip.
I also took the sled for a couple laps around the perimeter of the shore, testing for any sign of oppressive turbo lag or heavy nose syndrome. I crawled along and got in and out of the throttle; neither detriment appeared in my ride, but it was also shoreline riding, not picking through the pines on an actual trail.
One thing I'd like to see happen on the T660 is the installation of the hooked ZR bars. The unit I rode had the standard straight bar, and I have to say it made the sled feel a bit awkward and aged.
I grabbed Hallstrom as the introduction was winding down. He produced his radar gun and allowed me to hook it to my trusty laptop for some recorded runs. We used the new F6 EFI as a comparison sled. So this is what I found on January 23 at roughly -10°. The F6 dropped off the radar at about 800 feet, thanks to some nasty snow dust, but the T660 stayed on through the whole quarter mile and beyond. The top speed I ever saw on the radar for the turbo sled was 104.5 mph. Its speedo read 105 on that particular pass.
