Is a Strange S-60 more efficient than an 8.75", as in enough to help offset (some of?) the weight difference?
I'm trying to calc some target ET & MPH #s for my new combination. I know the Strange S-60 conversion has added some weight (not sure exactly now much; estimating 50#s) compared to my old 8.75". Neither old or new diff use spools; 8.75" had Power-Lok and S-60 and Strange has S-Track.
However, I've read here that a Dana 60 is more efficient than an 8.75" and the ETs are usually very close, despite the weight increase. True?
The weight is a push at best. When you get the 8.75 braced, used a NI case and all that, what weight you gain with the S60 is almost nothing.
Also, the weight is low and far enough back to almost not matter.
Also, the S60 is only more efficient when the gear ratios are lower (numerically higher) than ~3.90 otherwise that's a push.
If I'm wrong, Dr. Diff can come along and fix it, but I think I'm correct.
