Well, it's now race #2 and win #2 for the TNT Mods 21-5K. This motor continues to amaze me. I actually kept track of the mileage last night , and it makes very good run time. I've never had a motor with this much top end. It just never seems to run out, and to top it off it has a really good bottom end. Throttle response is instant, but smooth...almost electric feeling. The motor holds a tune and is temping at 237 every time. I can't find anything about this motor that I don't like! Thanks again TNT Mods for the world class power...definitely money well spent!
