This is what can happen through using a cone filter. It only needs tiny fragments of grit to get through and make a mess of the blades. I know I'll get shot down for this but I'm not the only one who doesn't like them.

That looks like normal wear from a high mileage turbo. The blades don't look too bad compared to what I've seen before. I tend to agree on cone filters. The reason most of them flow better is because they offer less of an airflow restriction, which means they are less effective at filtering. Here's a good LINK Hehe, I still run cone filters though.

What's with the locking tab washer, that's not even locked? I'd guess that has a nifty effect on air flow.

Then please find me a good alternative to my rotting Porsche airbox.

No, no cone filter. Completely stock car. The turbo has 15k miles since rebuild. Should I still run it?

Welcome to rennlist. Who is "we"?

Sorry, we are turbos unlimited. We rally race porsche's (996TT's). FIS Engineering provides us with turbos and we test them so we get to see alot of different units used on Porsche's. The main FIS branch for gasoline turbos is Forcedinductions.com. Sorry for the we part being vague...
