I was wondering how we get power break vacuum when under boost? Do we have a reserve to supply it for the short time under boost?

Looks like there may be a Venturi in the blower?

Also, where is the PCV valve? In the blower?

The ZL1 is a top mount SC so vacuum for the brake booster should rarely if ever be an issue. Turbo and centri blowers could be but rare. The top mount can supply plenty of vacuum at most all operating levels and the checkvalve integrated into the supply line and the booster keep a good supply stored and not bled back.
