what dash you guys using on your oil catch can and what is the difference between the -10 and -12. i am not asking about the size difference, just wondering which one to go with and why pick certain one. thanks.

 

Why dont you tell us what catch can you got.

 

Depends on alot. Whats your setup/How much power you making? Valve cover and block vented?

For 500-600whp setups, two -10AN on the block and two on the valve cover should be good. The more ventilation = less pressure in your crankcase which is a good thing.

 

i think -10 is good to go if you are using all 6ports (4vc,2block)

 

-10 is fine, most people use -10 instead of -12 because of costs. Plenty of guys making over 1000hp with -10 catch cans. I honestly don't think there's much of a big difference between them as far as performance, 1/8ths of an inch is not much.

 

I use -10 on all the catch cans I make.

 

-10 lines is all you need. -12 lines will make no differance in performance imo

 

I run two -10 lines from the back of the block to one can, and two -10's on the valve cover to a separate can. Plenty of ventilation IMO. And for what it's worth, I run a pretty loose p/w clearance, and I still haven't had any issues...

 

I only run 2 -10s on my VC, and the stock PCV. Havent had an issue with that yet. D16. 6262. 30psi.

 

I have 4 -12's.
2 on the valve cover 2 on the back of the block 1 is used as a drain back.

 

i have -10 on mine LS boost 300+hp

 

i run the t1 catchcan all -10 lines works perfect!
