I was just trying to figure out the gearing on this sled compared to the firecats and it seems to be they area geared waaaay to low. With the 60/60 (2.11 ratio) gears and a 9 tooth driver its equal to running a 57/63 (2.33) gearset with 10 tooth drivers, whereas a stock firecat runs a 65/55 (1.79 ratio) . If you run the stock fcat gears with the 9 tooth drivers you'll get a 1.97 ratio which is still geared lower than a firecat. Has anyone tried gearing up and runnning another sled to see if there was a difference or has anyone ran against the early build with the 65/55 to see which is faster. I can see now why they struggle after 85 mph to get any top end, I think theyre just out of gear at that point. Any thoughts?????????
