i searched and didn't find anything, so sorry if this has been discussed.

my question is what are you guys running for vacuum with H.O. cams. im only running about 12
last year i ran right at about 15

the only thing that changed from last year was the cams and ported the super charger which i don't think would affect it.



8 psi with m62 and IAT under 100

cant tell you with the supercharger... i know with the HO Exhaust and LO Intake i ran 18 at idle, and 22 when off the gas while driving (rev down)

with the .430s i have now (.020 bigger than the HOs) and i sit at about 16 at idle and and 24 when off the gas while driving (rev down)

I'm using an AEM Digital gauge
