HI Have 69 charger 440 low vaccum I need to add vane style power brake booster any suggestions on which would be the best cvr leeds or master power ? Thanks for any info.

 

Are you sure you need that much vacuum? Or will a canister with another check valve work ok?

Good Morning Bob, I don't know if another canister would help I only have 13" of pressure at the manifold it should 15" at bare minimum 18" to 22" would be great. The power brake's are rock hard know. Thanks Thomas

 

How about an electric vacuum pump Check with Summit racing

 

Thanks that's my next option Can't figure which none to buy?

I would go with another canister and vacuum pump for the camshaft.

 

Thomas -

I've been running about 12" at idle for the last 40 years on my 440 and have no problems with the breaks or anything else that's vac assisted.
If you're having issues, something else is going on.

BTW - I have a vac gauge on my instrument cluster, so I know exactly what the pressure is in real time.
