I was just wondering what other votech guys are running as a far as a vaccum pressure at idle?? Just mostly curious.....

Wouldnt it be boost?

Yellow Streak

No. Even if the blower was making boost at that RPM, the motor would be under vacuum and would be either blowing off or bypassing any boost generated. The vacuum level of a blown car at idle should be the same as what an NA car is at idle.

So, what does yours read?

Are you asking me what my car is showing for vacuum? If so, you'll have to wait until tomorrow - I didn't drive that car today.

Like someone else said, assuming you have no vacuum leaks and whatever engine management you're running is working properly, it should be the same as stock. I don't have an S2K service manual, but most modern Hondas idle right at 19 - 20 inHg with no accessories running. Flip on the A/C, and it will jump to about 17 inHg. You should be able to make an adjustment on the throttle body's idle control screw if necessary, but that's just a band-aid for poor tuning.

Yeah I know that, but I didn't have the boost guage hooked up when it was not supercharged. Im Just curious......
