Supercharger Boost- 32 lbs

I removed my Supercharger intake, without much surprise i wasnt getting any boost. The car's S/C whine was rediculously loud. My brother and I was trying to find a way to still have the boost and the sound at the same time. Soo, we wanted to see what we could do by just covering the tube up. We turned my car on and in idle i was already at 5lbs of psi... it dropped to 3 psi in reverse and when i shift to first i hit only about 2000 rpms when my boost gauge literally shot to 32+ psi and it blew off my S/C tube that my boost gauge was hooked into.. my car then died and i turned it off and checked our DIY clogging... it was fine.. :\ i then realized that it wasnt that it was the tube for my intake.. lol so any ideas that will allow me to continue at 12 psi and keep the sound?

Put everything back together like it was from the factory, and get a larger crank pulley. How are you at 12 psi in the first place?

Mine consistently pumps about 69 inches of mercury absolute without any unbecoming noises.

Isn't the factory kompressor putting out 11-14psi or somewhere in that range? That was my understanding.

i think it's 11psi for stock m271 230k. not sure about the m111. might have been 11-12psi as well.

and to OP, I think you have the boost gauge connected to the wrong place or your boost gauge does not adjust to atmospheric pressure. any supercharged/turbocharged engine should have a vacuum (neg pressure) when idling.

I wasn't aware these engines had that much boost stock.

Linden, ASP's pulley is a crank pulley. The larger diameter crank pulley results in more boost. Larger crank pulley diameter = effect of smaller s/c pulley diameter.
