I line up on the other side of the belt issue. The timing belt has been designed to withstand an engine that is revved out of gear which is certainly revving much faster than any engine in gear.

Yes, I guess most people would suggest the torque converter has ballooned and/or moved. The bearing noise may go along with that. When I look up at the TC through the housing slots, there is nothing notable at all. Everything looks normal, not that I would know what to look for as evidence of ballooning or movement. Had the bearing noise degraded any further I would be in there right now, especially if the clamp migration continued. But it seems to have stabilized. The car seems absolutely fine and has gets regular exercise. What do you think I should do?

Bill, I'd compare it to another car and draw conclusions, but more importantly go as far as opening the damn box up and finding the exact point of forward motion.

My to-do list includes replacing the TC bearings, and while I am in there I thought I would just go ahead and do the TT, replacing it with one of the rebuilds that includes the early shaft with the end clip. The TT seems to be fine, but at 155K miles with the original shaft, I know it's living on borrowed time. Actually, same thing with my steering rack! When will it just give up and start leaking?

I bought a used limited slip from you guys a few years ago, then decided I really didn't have a great need for it, so I sold it to Dennis Kao who puts it to very good use on the track. That was before the SC. Have any more LSDs for an 89?

You could do the world a favour and measure everything in relation to the body ..... to compare.

H'man: The TC looks to be right where it should be. I do need to get in there and have at it. I expected the bearing whine to get worse and force my hand, but most people would not even notice it.

Bill we have one which is not in a gear box but if you install it you will have to learn how to drive while fishtailing ! and the true meaning of throttle induced oversteer !

Nuther thought -

Are there enough stroker motors in use to know if there's any increased risk with them?

Marton: The AT is fine for supercharging and turboing. Maybe even better since you don't let the revs spin down by taking your foot off the gas when shifting. I see no evidence the SC does anything to accelerate the thrust bearing failure issue. In a few hours I'm going to go out and lay down a huge burnout in the parking lot here at work just for you.

Hey, I have dibs on the LSD. Yeah, I did notice Tony got kinda squirrelly while I had no trouble piloting my one-wheel-spinner. I'm through with this set of tires, so I am getting more interested in acquiring some traction with the next set.

Ah, thats no problem. Just an excuse for a stroker/SC for Bill. Glass is half full - of petrol.

If you are not familiar with Thrust Bearing Failure (TBF), my site has a lot of info and history of the "Loctite Fix" as a method of reducing thrust bearing failure. I make the claim that I have never heard of TBF on a car that has applied the "Loctite Fix". I don't know if this claim applies to boosted cars.
