Is there a way or has anybody thought of how they prevent apex seal from lunching the turbo in th event of a engine failure. Turbo rebuilds are expensive and I wouldn't mind saving that unnecssary expense in the event on a engine failure.

 

Best way is to have (or be) a good tuner.

 

Maybe an inconel wire screen in the manifold to protect the turbo, but it will certainly be expensive and will hurt airflow.

how big are these chunks normally anyhow?

 

It's not a requirement that when you blow an engine it shoots shards of damaging metal into your turbos. Actually, I would wager its more of the exception than the rule. Over the past 2-3 years, I've personally seen about 5 engines blow (including my own). None of them chucked seal pieces which damaged turbos.

Honestly, this should be the least of your worries with this car.

 

How about a NA setup? You will never have to worry about rebuilding a turbo ever again

 

+1.

It appears to me that the vast majority of occurrences where seals actually fragged and damaged turbos were caused by people pushing hard on unsafe engine combinations, or pushing for big horsepower.

 

kinda depends as well if you're single vs twins. Twins don't usually get destroyed - big singles do. I've blown myself and / or seen a good 7/10 single turbo's get trashed as a result of injesting apex seals.

 

I think it more depends on how much power is being pushed. Obviously, if some single turbo gives up the ghost trying to push 500+rwhp, it's bound to do a little more damage than simply crack a seal.

If anyone is really that concerned about it (and IMO, if you are pushing enough power to do that kind of damage, you should just expect to loose the turbo in that case), look at using something like the NRS Rotorsports ceramic seals.
