im going to be building a similar catchcan setup to T1's.
Gonna run to the 2 on front of the valve cover and then have the 2 return hoses go to the back of the block.
Im using -*8AN fittings because i get them free at work.. and i have free hoses too so im just gonna fab up a steep box and make it work.

SO will the 8AN be big enough? should i add extra ports since they are a lil smaller?

Im Running a Benson GSR block 530 WHP. and my ****so can pukes here and there and messes up the engine bay that i like to keep clean.

 

the smaller the air channel the more oil the air will carry. that is bad.

the larger the air channel means the air flows better and oil doesnt go with it.

your setup might work but it should move a lot more oil than is necessary

 

depends all on how much blowby you plan to have
