Turbos knocking out thrust bearings I've talked to a handful of people this week that have had issues with knocking out the thrust(Crank) in the engine. Everyone is turbocharged. Do the converters balloon that much or is something else causing this?
I'm far from an expert but if/when a convertor balloons doesn't it pretty much stay that way? I've always checked by unbolting the convertor and sliding it back to ensure it wasn't pushing the crank in. I don't see why a particular power adder would be harder on thrust bearings than another?

Phil,
What trans?
My buddy ran a 434 SBC, twin Exile 47-88s with a Bruno trans and he was constantly killing the thrust bearings in it. Is was converter related, but I thought he said there was something else as well regarding it. I will ask him if you have the same trans. He sold the trans and now has a three speed back in the car. My other buddy Giuseppe Gentile got him to ditch the bruno and run another three speed.

I half think that, if this was the cause, we would be hearing about it more often....and not just on turbo cars but all power adders.
Is it linked to one type of converter? Are they OE or discount aftermarket?
Also, if the converter balloons, how much can it expand before it fails? Wouldn't a big increase in tolerances inside make it noticeably inefficient?

The converter would certainly take a brunt of the force generated, and it has to go somewhere.
i just spun a bearing, builder said it was the thrust bearing out and due to the converter pushing. t400 converter pro edge 4000, 88mm, on a 370. should i send the converter back to get redone or what?
I think 2000+hp turbo cars are just a little more common than other forms of FI. Poll some real high hp procharger guys, and you might find the same problems. Kind of a numbers game.

we have found it to be torque converter design causing this,ATI has fixxed this problem in thier converters,that is the reason fireball had no thrust issues
