Front Engine Dragsters / Re: The boys from Kansas are at it again

« on: March 09, 2015, 02:49:44 PM »

I know that over the past sereral years the rules and requirements for the Junior Fuel Dragster Association that races the Heritage Series on the west coast and the Southwest Junior Fuel Association that's in the southwest part of the county have developed some differences in the rules and requirements. The SWJFA runs their competitions heads-up; light turns green in both lanes at the same time.

Jon Hansen can probably talk better about the handi-caps used as a competition equalizer in the Heritage series among the 3 different classes. This is the format they were running at the March Meet.   GO BANG SHIFT.com, you rock Chris! Hope none of you missed the excellent live coverage.

Thought I’d throw in one more option for a raised pinion position. Winters make a non-quick change that mounts the pinion centerline directly in line with the ring gear centerline. Whole thing is like ‘32-’48 Ford rear with a center banjo and side bells. My dragster has one of these units in it and it appears to have worked for the last 10 years in a junior fuel car. With its spiral bevel ring and pinion, it's more efficient, uses less power to operate, and runs cooler compared to a typical hypoid rear-end. The centerline of a 12 bolt is 1 ½” lower and the centerline of a 9” is 2 Ό” lower than the non-quick change. Down side, it’s more time consuming to change the gear ratio. You must split apart the rear-end to make a gear change. Went 7.40s @ 180mph on the left coast, first race out for me last October ran 8.40s @162 with a mild tune-up. Have pictures but are to large to post here, sorry.
