Well, as usual, when I get in a pinch for new stuff at a decent price I call my old buddy Ronnieboi Owens.  Ron got me the parts I needed to complete this rear end rebuild and they got here Post Haste!  \:D/  Here’s the finished product, and yes, the beer is necessary when jobs like this come up.  I gotta get drunk to enjoy the $700 it cost me to put this thing back together!!!  ](*,)

This Moser housing is killer!!!  The bolts in the caps are great big mammajammas and I had to put a 15" pull handle on'em to break the loose.  And look at the mass in those caps!!  Dayum!!  Next time I'll be on the roof!!  O:)  Cuz this housing IS NOT GOING TO BREAK!  O:)

Image

And for those of you that don't know what a good tooth pattern is suppose to look like, here's an example!

Image

And while we’re at it, here’s a pic of Ken’s welding table/transmission shop/rear end shop/Geo engine shop complete with flammable goods under the bench! O:)

Image

So the center section is assembled and waiting to be installed tomorrow and Pit Bitch and I will be at Piedmont Dragway on Sunday to see if anything else is horked up!!  ;-)  Oh, and yes Scott, there is a 5:14 in this new setup!!  ;-)

Hey Ken,that looks like an aluminum center,I thought you were going with iron?  
 If that is aluminum that is the same center I run in mine and I noticed in the pictures that you posted of your old center that the caps on the old one were tiny,that is why I asked who made it .
 I feel much better letting go of the transbrake button knowing those big thru bolts are in there,even with my little engine,did you use 3/8 or 7/16 bolts in your pinion support?

Jeff that Moser center section is NODULAR IRON, not aluminum like the Strange one that was in there before.  I painted it with a silver hammered RustOleum paint and is just looks like aluminum in the picture is all.  

The Strange aluminum case had held up pretty well until the reverse deal hit.  I really can't bad mouth a broken case when it was my stupidity that actually broke it.  And yes, the thru bolts on the caps is a MUCH better way to go and if I ever own another aluminum case it will have that feature.  The one I broke would do fine for a lower HP application or a dragster.

It's been said by more than one person that there is more flex in an aluminum housing and that gears will last longer in an iron case so that is why I went with iron instead of aluminum.  That and an aluminum housing would have cost me over $100 more.  Moser says that this nodular iron case is only 15lbs heavier than their aluminum one but it feels like it's MUCH heavier that that.

Anyway, it goes in the car this morning.

I noticed the color too but I could tell in the one pic that it looked like it had been painted.

That is the same case I run in mine. About 750 hp in a 2300 lb car. Gear life in mine is less than that what I had hoped, around 150 passes at a time. I think I'm going to the iron one over this winter.  I was getting 500 passes out of a gear in a heavier car with the same motor & transmission with an iron case.

Ken it could be the Moser aluminum case has a lot more material in it than the Strange one does.  They did tell you it's 15 lbs heavier than THEIR aluminum one.

I noticed yesterday that in the Moser catalog the only center section they offer for their 40 spline axles is the aluminum :-k ,it seems strange that a "weaker" center would be used for their strongest axles

Test run on the jack stands just now didn't show any problems with the tranny and oil pressure at startup went to 80psig so I guess it's safe to say that the old gauge was toast!

We're off to Piedmont Dragway around 10:30 so I'll know more about the converter then.

My axle is completely moser and thats got a 40 spline shaft with a cast iron centre section..

I think I may need to change ratio's with my new engine, I'm going to run it first.. I'd like to go with another moser in aluminium and drilled shafts etc, I'd think you could lose 40 lbs if you went with the lightest stuff and about 2000 bucks.. car diets are not cheap !!

You are right Sam,I was not paying enough attention to what I was reading, Moser  pro spools "the best professional spools available"-" must be used with the 3.812 bore aluminum case"

 You are right Sam,putting these cars on a diet is expensive,but I try to but lightweight parts whenever possible.

Made 5 passes and brought it home in one piece.  I'll let you know how it went after I get a chance to look at the logs and the time slips.  

But it was a good day!

Best run was a 5.54 worst was a 5.57 when the car made a right turn off the line.  Short times were up and down but all in the teens probably because there was about a gazillion street cars there horking up the starting line.  That and there was a couple of broken rear ends complete with oil downs too.

Scott I'll send you the logs and an Excell file if you want'em.  

The good news is the transmission and converter seem to be OK at this point and since the new gauge fixed the oil pressure problem we'll probably keep on running until they close down for the winter after the first week in December. ;-)

Ok did the 5:13 help or hurt?

We had some decent air here this past Saturday night.
First runs with the new 5:13 gears. We pulled out 4:86

Went from 1100 feet to 600 feet.

7 passes from first time trial to 4th round runner up from driver error at the finish line.  [-(  [-(  ](*,)  ](*,)

#1  1.224  3.565  5.194  5.559  @ 123.25
#2  1.224  3.548  5.167  5.530  @123.66
#3  1.217  3.541  5.164  5.527  @123.93
#4  1.219  3.536  5.150  5.513  @124.00
#5  1.202  3.516  5.131  5.493  @124.27
#6  1.202  3.514  5.128  5.486  @125.69
#7  1.200  3.507  5.129  5.529  @112.27

Looser converter is on the way.

Looks to me as though driving the finish line bit you in the ass! O:)

#1  1.186  3.563  5.550  124.30
#2  1.196  3.573  5.562  124.12  spun the tire leaving
#3  1.180  3.559  5.549  124.15
#4  1.179  3.553  5.541  124.27
#5  1.191  3.582  5.576  124.18  made a hard right turn at the hit

As I said, there was a bunch of street cars there and on that last pass I was the first car behind three of'em so I guess that's what happend to that run.  So throw out the second and fifth and it doesn't look bad.  We'll know more when we go back to "The Bridge" in two weeks cuz that's where I've been actually racing.

Last October we went 5.52 with a 1.16 short time at that track so even with the added weight of the cast rear we're actually making more power than before.  All these runs were with 15* of timing out at the hit that was ramped back in over .76 seconds into the run so we did leave some performance on the table.
