3sgte recirculated, Now with PICS! Options

[jgreening]

Today Carl at Speed Source made me a new intake so I could recirculate my Greddy BOV. Here are the results:

1. No more backfires
2. No more puffs of black smoke out my tail pipe
3. No more ricey BOV sound
4. Better response after shifting

All in all, a great mod - unless you like the sound (which I don't).

Here are the pics:

I don't understand. We are talking blowby here. The intake charge has already been ingested by the engine correct? The blowby is an air / fuel mixture.

I can tell you that my bogging, smoking, and backfires have all stopped despite my PCV vented to atmosphere.

From the information I have read tonight, it seems Art is correct that the rerouting back into the intake (or exhaust for that matter) serves as a vacuum source for the PCV to help the blowby exit. Another thing I don't understand is why a vacuum source is needed. I don't undertand why that air doesnt just escape without the vacuum source.

it does escape on its own... but the vac just assists it to let it do the job better and faster.
