If someone is out there machining the inside of diff carriers and side gears to spline in clutch plates and make a 'real' LSD for any kind of reasonable cost i probably know a fair number of people who would be interested.

Steve has sold dozens and dozens of them …like I said, even SpeedSource uses (or did when they were running RX8's … don't know about the diesel)

Boy did you ask the wrong question on the wrong site to the wrong group of people.

Not sure what you meant by that, but the post with the least amount of useful information so far is yours.

Chuck Noonan set-up my FX16 back when it was new in the 80's. He was a great guy. Always willing to help. I was saddened to hear about his passing.

It did work pretty well considering that it was the only option at the time, but once I added a turbo it would give up in hard tight corners. Even with the turbo it was fine on a road course. I probably only put 10k miles on it after that point, so I don't know how it would have held up over a longer period of time.

More power requires stiffer springs between the plates.

Yes, but there's a point of diminishing returns, as more spring pressure results in more wear. It's a decent and affordable option when nothing better exists, but I think something better now does exist for my application.

Yeah, me too. He did a bunch of work for me back in the late 80's. He was a really nice guy to deal with.

you'll do as you feel you need to … that said, how much hp do you thing the SpeedSource RX8's were putting down at Daytona in yrs past ? these LSD's worked fine for them

The reason I'm not using that type is because of wear, not power. As far as SpeedSource goes, it's no big deal for them to tear down and inspect the diff, and I'm sure they do. Its also an entirely different car and a different use than I have, so I'm not sure it's comparable.
I want to put it in and forget about it. I've already used the block and spring type, and I know that they wear out. I also know you guys are big on this type, but I see no reason to use something that inherently wears when I can use something that doesn't.

Like I said before, I made mine because nothing else was available. They do wear, and to handle more power in the same package you have to add spring pressure, which adds wear. With helical style units now available, I just can't see using the block and spring unit. The other factor is that I want to have it in hand when I take the trans apart, not take it apart and wait however long it will take to get it back.

So the relevant question is whether I should use the MFactory, OBX, or Quaiffe unit. I have no experience with any of them, but have read that people have had a problem with axles getting stuck in the OBX because the splines aren't hard enough.

Ive heard obx are fine as long as you take them out and "blueprint" them some people have found loose bolts, friction material and plates stacked in random order blah blah. Disassemble, reinstall with loctite and they seem to be fine for the money

OBX is a helical LSD which uses helical gears, not clutches and plates.
