I have restrictors in the MAP and FPR lines to minimize the pulses you described. With ITBs and a large street port getting a stable MAP signal is difficult enough.

I have a small vacuum block for the FPR and MAP. It has extra ports to add in the second rotor, brake booster, charcoal canister, and oil catch can. I thought I read something somewhere that said you should keep the brake booster separate as it can cause vacuum fluctuations when the brakes are applied.

Would I want to have everything hooked up to one source? It's not a turbo car so there should never be positive pressure but I'm hesitant to have the FPR and MAP in the same circuit as the oil catch can and charcoal canister. Is this an issue? This is not a DD/road car so I'm not concerned with emissions. If there's no value I'd just assume vent the oil catch can to the air and delete the charcoal canister.

That's my main question. My current setup would draw the catch can and canister vapors into only one rotor. If that's an issue I can merge my vacuum setup but then I have the brake booster, MAP sensor, FPR, oil catch can, and charcoal canister all in the same "circuit." If that's not an issue - great! That all being said if there's no value added to applying vacuum to the charcoal canister and catch can (i.e. make them work better) I'd just assume delete the canister and vent the catch can. It's not a DD or really even a road car so I don't care about emissions/smell.
