Tried to take advantage of the good October air and pick up a new personal best at the track last night and am now instead looking at what to do with the broken teeth on the side gears in the Eaton posi carrier.
Got a year and half out of this rebuild, but might have pushed it too far. The DA was down to 8,000 ft (great for Denver) and I went one size smaller on blower pulley (from 9 to 11 lbs.) and took my personal best from 10.59 to 10.42, as in signature. Next run I spun badly in part because the temperature was down to 48-50 degrees and hit the rev limiter. Next run a loud clunk at the line as it hooked, so limped off the track.
A part of the problem may be that I went to a Hoosier DOT drag radial a couple of weekends ago, which dead hook, instead of the bias plies I was using. Hope thats not the problem, or stuck with an expensive, recurring problem. Will certainly take the boost back down to 9 lbs.
Should I just change the side gears as ring/pinion look good, clean the housing as Strange axles w/ C clip eliminators have separate grease, and run the last four race days of the year, or go thru the entire unit, which requires R and R instead of just carrying the carrier into the shop for sidegears and clutches, and will probably miss next weekends racing - both days. Will check the backlash, but expect it to be within spec.
Engine is about 725 HP and pushing the Eaton carrier's limits, but footbrake at only 2400 RPM which is still a pretty soft hit, or so I want to think.
Could do a Moroso Brute Strenth unit or another type after the season, but want to make this weekends racing, but don't want to do something dumb either. Hope its not going to be an ongoing issue with the dead hook type tires. A new personal best doesn't seem so important now, but it may not have had anything do two with 2 more pounds of boost or the DOT radials, but those were the recent changes.
