A good news is I just installed a Auto Meter 20lbs boost gauge in my car today, it is really fun to watch the boost level while driving.
I noticed that the boost build up from the supercharger is extremely fast compare to those turbo car. It locked at about 10psi under 5000 rpm(3/4-full throttle), but once get above that, the boost is up to the maxium until redline. In second gear, I read a maxium of 15psi at 6000rpm. In the third gear, I read a maxium of 16.5 almost 17psi at 6k rpm(
WOW) Also, I got vaccum reading about -18psi in the idle.

(2.04 in-hg = 1 psi) so... -18 psi*2.04 = -36.72 in-hg... can't happen. (30 in-hg is a perfect vacuum)

10 in hg = 4.9 psi
15 in hg = 7.35 psi
17 in hg = 8.33 psi
hmmm...those #'s are realistic
also the gear it's in has nothing to do with boost except that he would have more time to look at the guage and for it to stabilize .
