GERRY - You very rarely see supercharger drive belts break on nitro race cars anymore, they must change them every round. On a 5-6 engine pulling tractor you're just about guaranteed to see a couple blower belts break during a pull. Pullers don't spin their 14-71 blowers as hard as drag racers, (I always have to laugh at a "14-71 blower", DDA never made a "14-71" engine, 6-71, 8-71, 12-71, 16-71, never a 14-71)
The diesel & alcohol super-stocks are really cool, I especially like Brian Korth, from just down the road 30 miles around Beaver Dam, WI. Beautiful Case/IH's "Armed & Dangerous", & "Excessive Force". Brian jumped away from the NTPA circuit two weeks ago to compete in a charity pull in Hillsboro, WI sponsored by Lucas Oil on the Pro Puller's circuit on MAV-TV. He spanked his old pulling buddies pretty good, took 1st & 3rd place points away from the regulars!
Also on the Pro-Puller's circuit there's Nick Skaar on "Screamin' Norwegian", who lives about 12-14 miles away, also a new Case/IH. There used to be a real active puller's club around here 20 yrs ago and Nick would come in and beat up on everybody with his dedicated 1066 puller. There was one 4430 JD that used to come close to his distances, even saw the JD win once or twice. One summer SON & I went to watch pulls at least every other weekend if not every weekend. A co-worker pulled an antque Super 88 Oliver that was more like a 1950 Oliver. It's amazing the work those people do to "get an edge" over the competition!
