Looking at adding a catch can to my car. I'm gonna be running a 2 3.5 with sti heads etc, md turbo, gonna be running approx 450bhp. Was wondering what size catch can to add - 0.5, 0.35 or a litre? (thats the sizes i've seen so far).

 

If you're in Essex give Zak @ Mocom Racing a ring he does a baffled one at a good price. Got one of mine
