Can anyone point me in the right direction for the correct changes to be made to releave crankcase pressure under boost. parts, pics etc

I have a breather cap but I don't think it's enough.

Thanks.

First, you NEVER want to vent! Your breaking the system and defeating functions that keep your engine alive and relatively wear free. You want to implement a system that pulls suction on the crankcase at all times so pressure can never build to begin with. This also removes most of the damaging compounds that enter as blow-by before they have a chance to settle and mix with the engine oil. Our E2-X Ultra system is designed just for boosted applications and retains a closed emissions compliant system except in CA. Tell us more on the type of FI you have and we can provide illustrations and guidance on doing this right. Venting is decades old outdated tech that is not used in any form of Professional racing except T/F and T/D (nitro dragsters) as they push most oil from the crankcase in one run and engines are rebuilt every run. Only those without knowledge of proper crankcase evacuation use or recommend venting.

Not sure how much hp, never dynoed it.. stock l99 camaro at 7psi boost. Twin turb, rear mounted. Email tuned, 1000cc injectors, zl1 fuel pump. Stock heads cam and converter. Cats and mufflers removed. Afr starting at 10.6 in boost and ending at 11.4 before shift.
Boost timing starts around 18 or so and drops down to around 13 degrees based on map values... it's been a while since I checked tbh... no detonation issues so even if there is power left on the table (there is) I'm happy.

I do have a catch can, don't think I plumbed it in correctly though. The valve cover breather was just for cheap insurance.
