Build a TH200-4R For 1,000 HP
|
Stock TH200-4Rs get a bad rap in high-performance applications due to a weak intermediate drum assembly. On this cutaway, the pen points out the failure-prone undercut. Carr used Kenny Duttweiler's 10-second Buick GN as the test mule to research the problem. At first, he tried a welded bead to fill the area and eliminate the stress riser. It helped, but occasional breakage was still an issue. Carr then considered the metallurgy of the part, and after some trial and error, arrived at a proprietary annealing/heat-treatment process that triples its strength. Problem solved.
