Sounds good, need a price quote then and I will get your info on the fitting

gmc i have done some with no fresh air inlet before. let me know when you get the can and will work it out

should still work fine but if it draws too much we can always cap one of the can ports

unmetered air if you use a maf

also under high winds (wide open or in boost) there is a draft at the throttle body if n/a, and below atmospheric pressure in front of the tubo/sc that will provide additional scavenging of the crank fumes.

MM can I get a pm on a can too, which options is there? Looking to use it on my procharged ls1. I understand your picture with how to run the lines but what about check valves and pcv valves, where's the placement of these to work properly?

pcv valve is included, mounted in the can. nothing else is necessary other than hose and mounting location of your choice, i strongly reccomend NOT attatching it to the cylinder head.

here's a common location

What sizes of hoses do you recommend?

Who is running a catch can between the turbo air filter and valve cover?

I'm concerned about pulling oil into the compressor when in boost.

In this picture, why is the rear vent on the passenger going to the top throttle body. I have seen the front passenger nipple go to the top throttle body in the Saikou Michi and Revxtreme set ups. Any reason for this? Also is the stock PCV still needed in this set up? I am NA btw.

the line out of the top of my can is a metal boost proof pcv valve. stock valve no longer needed.

for the catch cans i prefer to pull from the valve covers on a diagonal, so if accelerating hard or braking hard, one is always open (not flooded with oil)
