I use to race the gt every Saturday. I had a sirio 12 outlaw in it previous to my new OS 12 cv.
It was too much power. I had trouble keeping the power to the wheels. I had to really
feather the throttle to keep it from spinning out.
With the OS, I felt that it was much more suited for the track. At first, I had to restrict
the carb until I got use to it. Then I took the restrictor out and let er rip.
In Stadium truck, you dont need so much power.
