The chart below is from GM High-Tech magazine. Take a look at how much less horsepower the Moser M9 uses compared to a Strange S60! Bob
TABLE OF REAR-WHEEL HORSEPOWER/TORQUE CHANGES:
Car Rear Old HP/TQ Rear New HP/TQ % Loss
Jensen Camaro Stock 3.42 412.5/390.0 Strange S60 3.73 397.9/376.0 3.5/3.6
Werner Trans Am Stock 3.42 441.2/432.3 Moser M9 3.70 436.6/428.6 1.0/0.9

I wish people would stop quoting this article as a way to sell 9-inch rears. The article is so flawed. We have NO IDEA how worn those stock 10-bolts were in each of those cars. My old 10-bolt probably sucked 2 hp to spin it. You could turn it with your bare hand quite easily. It is entirely possible that the 10-bolt from the Trans/Am in the article was much tighter so there wasn't much of a change between going form a tight 10-bolt to a new 9-inch. Plus keep in mind that after a few hundred miles the rears will geta little easier to spin.
As far as the weight goes, my Dana60 weighs 185lbs. I have a spool, the aluminum rear cover, the hytuff axles/35 spline, and bigger studs. Install time was around 1.5 hours. The rear is capable of 1500+hp beatings.

When Steve from car craft and hot rod magazine did the test with 3 rears all the same ratio, all new... It wasn't like that article, story

Just a warning though if you trim the UMI bracket it won't be warrantied if it breaks. It's not a expensive part to replace but just have to repeat the process over again.

UMI's website has all the pics on installations of their parts. According to UMI tech support Jerry, their torque arm should fit the S60 with no fabrication/cutting whatsoever. I just finish installing my S60 but with a Spohn torque arm. I had to cut the top bracket plate of the Spohn t/a that mounts on the top side of the S60 in order to fit correctly(used the outer two holes). Hope this help some.

I'd give eric at Midwest chassis a call. That's where I got the best deal on my S60.
I might point out that the S60 is going to cost you some time, as they don't exactly have a warehouse of them ready to bolt in. They build them as the order comes in. I sent them my backing plates/reluctor rings and it took over a month to get back to me. I'd get Eric to get you his driveshaft instead of the strange shaft. It was a little cheaper, faster to get, and probably better than what Strange was offering at the time.

Not to highjack the thread but I have a question. Do any pro stock, top funny cars or top fuel rails use 9" or s60 or is there a differnet rear end they use? Because I see more s60's in faster cars then 9" at the track.
So what about it takes more power to run a s60, aren't they supposed to be bullet proof. i say that because all I see is s60's in 7 sec cars. The way I'm looking at it when I order my s60, is I get another reason to make more power and go faster.

The S60 is actually more efficient than the 9" or the 12 bolt. Magazines put out very flawed information.
I run the S60. It's a great street/strip rear end. The TruTrac is a truely streetable posi unit with 35 spline axles making it much stronger than the 9" version. While many are listing the weight as a negative, if you think about where the weight is, it couldn't be in a better spot. My car hook RETARDED. My biggest concern is not going up on the bumper..........downhill............in the rain. LOL
The only major downfall is that there aren't alot of gear options and nothing with a closer ratio than 3.55. I would love to have a 3.2X ratio available.

Both rears had quite a bit of miles on them, and were otherwise in perfect working condition. The test was done as scientifically and fairly as possible, however, that is not to say that if you were to replicate the same test you would have exactly the same results. Considering the many other factors that should go into choosing a rear, I wouldn't let this be the deciding factor. If efficiency is that great of a concern, than you should be looking at a 12-bolt.
