So I have a 99 corvette 110k miles and i put twin turbos on it and also a breather catch can. How much condensation should I be getting out of the catch can. This is with just around 100 miles.....

Depends on weather conditions, tank location, engine temperature etc etc

Connects to the engine at the back of the driver side runs up in front of the intercooler behind the frame crossover.

I live in Oklahoma so it has been colder. I do let iit get to temperature when I start it

If the can is remotely mounted from the engine, and worse still in a much cooler location, amplified by cooler weather, then that can create a lot of condensation.
Add to that further an engine that might run cooler than stock..ie below boiling point of water that might help eliminate condensation within the crankcase area.

As long as you arent losing water from elsewhere....I'd just keep an eye on it and ensure the can is regularly emptied.

Engine hasn't been over 200° I finished it when it started getting colder.

This last time I started it there was a ton of water coming out of the exhaust. But others than that I have a very slight leak of oil (maybe 3 drops in months)

Turpid porpoise

Are you running pump or E85? E85 will fill your can up much quicker than 93OCT.

E85

E85, cold weather and the can is located away from the engine heat so I'd say it's fairly normal, maybe a bit more than I'd expect.

Do I need to move it closer or it's fine just make sure I dump it?

stevieturbo

It's just hot moist air, condensing on the cold can. There really isnt much to fix it as such. Engine mounted with direct heat might help reduce it a good bit. But that isnt always practical depending on size of the can etc.

It's a lot for 100 miles...so you need to keep an eye on it and make sure it's emptied regularly..

Some other designs, like the Crawford Performance air oil separator for Subarus, run engine coolant lines through the can to warm it and reduce condensation.
