I live my life a quarter pounder at a time. And for those 500 calories or more, I'm free. I need FRIES! Two of them. The big ones. Oh, and I need them tonight. You're lucky the double shot of BBQ sauce didn't blow the seam on your nugget box. There she is, 2 pounds of pure beef. My dad ate it in 9.0 seconds flat. Check it out, it's like this. If I lose, winner takes my happy meal. But if I win, I take the burger and the toy. To some people, that's more important.

Just kidding
So other than noise reduction they don't perform any other tasks? I'm not really worried as the car seems to prefer staying low on the curbing, rather than get upset by going over it, and potentially lifting a wheel off the ground. I'm just curious.Last edited by Inspector 24; 04-10-2009, 11:48 PM.Ryan

I had another track session today.
Had a late night last night and put the LSD-box back on after having the shop go through it again - they found something wrong with the 5th gear synchros, changed those, and the tranny was shifting fine in every gear after that. I bought a brand new axle, put that on, and put in a spare clutch disc to make the car road worthy again. I figured I should give it one more shot before the down time while the PAR-geared box gets made.
Thus far the only unsatisfactory thing is the driver side axle not going in all the way. It's about 3/16" from full engagement against the gearbox and its seal. Not only that, but it moves a further 1/8" out pretty much at will.
The problem with the first 3/16" is that it allows fluid to leak out. Not gushing, but within a 1/2 mile of driving the bottom of the diff. housing is wet from the fluid seeping from the gap between the seal and the shaft. Also, while driving and coming off the throttle, you can hear the rattle of the axle moving in and out for that 1/8".
The axle is brand new, and it did the same thing with the previous axle, and Jon had the same experience when test fitting.
I made 2 passes, and the 60ft times were consistent with previous outings - 1.70 and 1.78. I had some full boost electrical issues (had electrical power cut out over 20 psi for some reason), so I didn't really get full passes, but did enough to put the diff to work through a few gears. I would say the launches were mildly aggressive, with a 'soft' clutch drop at 4800 rpm off the line. I'd say there is another .05 to a full tenth left in there if going all out.
Burnouts were where I saw the biggest advantage - no more single spinners, very consistent on both tires.
I was getting the axle chatter on the return road both times, and it's that 1/8" of travel (see the video).
I'll tear down this transmission in about 2 weeks and remove the LSD for inspection for now, before reusing it with the PAR gears. I have a show to make in L.A. next weekend that's been in the works for almost 8 months, which is why I'm leaving the transmission in there for now.
This outing only cost me about $275...

Hmm, so it sounds like the problem is that the axle just can't push in far enough to stick, and/or there is no space to let it lock in place inside the LSD.1990 MX-6 GT'ALITA' 2nd Gen Struts & Springs Dutch FSTB, Manual Belts & Windows

One thing of note is that Jon said the same thing happened with his stock diff as well (the play). Could you try your axles with your stock diff also to see if this play is present for you.MFactory / YCW Engineering (LSD's, Gears, Flywheels, Clutches, Driveshafts, Axles) - www.teammfactory.com

I noticed some play with the stock open diff but there was more play with the MFactory unit. to me it didnt seem like it would be a problem, but i obviously didnt have it running in a car. if its leaking and making noise, the additional play must be too much.
I'm sure we could easily come up with some inner axle stubs to send over if needed.Escort GTR -- 11.87 @ 117.6 mph -- 320 HP / 325 Ft. Lbs. @ 23 PSI

Agreed, I've got plenty of spare axles around, would happily supply a grease free example.
And I certainly don't have any problem with the play as long as it can't possibly affect performance or reliability to the tune of 30+ autocrosses a year, 5-6 track days and all the traveling in between.
I've got three G-Series tran's sitting in cars at my house, I'll take a look at them to see if any have similar play.
