Vacuum Gauge?
Just a quick question about a vac gauge. If I hooked a vac gauge up to my N/A intake, would it be able to measure a noticable vacuum? Of course I'd run the gauge to the the throttle body, I was just wondering how much "vacuumness" there would be. Thanks.

I'm not sure what kind of vaccuum you'll see, I don't have a vacuum gauge on my truck, so I don't know what typical numbers are. But if I were to guess (and this is just a guess), I'd say you'd probably pull about 20 inHg of vacuum at idle and 0 inHg at WOT.
edit: it may be interesting to run a vacuum gauge before the butterfly. any vacuum there will show you how restrictive your intake is. but these numbers will be much smaller than a typical vacuum gauge reads, so you'd probably have to get a special vacuum gauge for that.
