Normal vac numbers?

[Mistascott]

What's a normal vac number on the gauge? I am getting 15-16 in. at closed loop idle.

Sounds normal for a stock cam to me. :)

Nice avatar Mistascott. :goldcup:

I usually see about 15-16" at idle. It's about the same in gear. HTH.

Yah, great avatar.

I shoot up to about 20 in. after I boost. I think that is healthy too. I was just worried that my vac block was leaking because those hoses are old and I can't find any new thin ones. :mad:

Yah, if I crack off the throttle, especially coming from boost, I will see numbers in the 20s of vac. Sounds healthy 2 me.

Funny, it seems that every time I look at my gauge it is showing 15+psi instead of vacuum, something must be wrong with my car :fragez: :fragez: :fragez: :fragez: :fragez:

:racer: No, that's perfectly normal. :burnout:

My car has a stock cam...

I get about 15" in warm (closed-loop) drive, about 17" in park.

Good Luck,
