for those that gutted there cats
was woundering when you gutted ur cats did you compeltly get out all the left over litllte bits that are left on the side. and do you think those little shards mess up the compressor wheel

??? Catalytic converter "parts" will never see ANY part of your turbo, much less the compressor. What pieces are left in there, will likely get blown or burnt out of the muffler eventually?

Catalytic converter parts in your turbo? NEVER happen.

You mean like the STS system that leaves the stock exhaust in place all the way back to the turbos?

Yes, the turbos were mounted after the cats (which are under the cabin) where they scavenged the exhaust air and then sent it back to the front of the car.
Here they are on a C6, the only thing post turbo is the exhaust exit. The plumbing runs from the turbos back to the front of the car through the rocker panels. Great for ease of installation, bad for lag!!!
Also bad if you have a 427 C5R block that puts out enough heat to melt the cats and send particles through your turbines which could then send them back through your engine intake.

The exhaust side and the compressor side of the turbo are two separate sections on a common shaft. There is no chance of anything that comes out of the exhaust turbine to get into the intake, unless the air filter falls off and the debris gets sucked into the compressor side of the turbo. Cats that come apart will be consumed by a rear mounted turbo and then come out of the tips.

I don't know what any of that means, all I know is that my cats came to pieces, and my turbos were shredded.
When I talked to STS they told it was very likely that the shredded cats caused the problem. They were very gracious in sending me several replacements under warranty. Great group of guys.

When your cats came apart they did damage the exhaust side of the turbos. The cat particles could not get into your intake.
I have had pistons melt and not hurt the turbo on their way out. When something solid goes through a turbo there is usually a big bill to follow!!

I figured that you were running very lean and building lots of heat in the exhaust to melt the cats. Probably cost you a set of turbos, a set of pistons and a few valves?
Bad tunes are easy to get but good tunes are priceless!!

Actually if you really want to hurt a catalytic run rich, the catalytic will try to consume the fuel and get QUITE hit - as in cherry red glowing melting hot with smoking carpet in the cabin if you aren't careful.... Lean shouldn't hurt a catalytic too bad unless piston pieces are exiting :-O
