So i have a 502 big block with a 671 B&M super charger. I'm running about 6LBS of boost. Now here's my question. I know i shouldn't have any boost at idle and for a while i don't then after about 15-20min i see boost building up on the gauge around 10LBS or so... so is it just building up presser in the intake? when that happens it starts to get a little warm too. i know the gauge is hooked up in the right place (driver side in the front on of the intake.) so i'm a little confused here.
