ok, just want to know at what value your gauge reads at idle(750 rpms)



in other words, what is your vacuum? ...by measure of mmHg

cause if 760mmHg = 14.7psi, then I have 9.2 psi of vacuum ...and have since the motor was rebuilt



it also means the gauge reads no more than about 15 psi of vacuum if i recall correctly

15-20mmhg is ideal, but 20mmhg is best on any gauge.

Do you mean 15-20mmHg, or 150-200mmHg? 'Cause I get 200mmHg at idle.

15 to 20mmHg, how the **** are you getting 200?!?!?!

mine is pulling around 400mm/hg at idle, it varies with the weather

-300 mmhg to -200 mmhg says the avcr

turn off your anti-lag. maybe that's the problem.

did you get your motor ported when you had it rebuilt? and how long ago was yoru rebuild?
