I've got a couple of questions about my charger.
Is anyone running a charger with the hbp on a auto transmission?
What fuel psi do I run on the fuel pressure regulator with the stock pulley and the what psi for the hbp?
Is there any solutions for the occasional sweaking noise from the pulley?
My stock pulley is pushing 5lbs of boost, what does the hbp push the boost to? I think the hbp that I have is from Comptech.
Im new to the charger scene. Any help is greatly appreciated. Im happy with the stock pulley, but I was expecting more, unless my car isnt tuned correctly. Im considering going with the hbp but I dont want to damage the transmission or motor, any suggestions?

Final question, is it worth getting the b pipe on my car with the charger? I have CT headers and axle backs.
I hope I can break 13's in the quarter with the charger!!! I think I'll be going to the track next week, we'll see what happens!!!

You should be around 38psi on the stock pulley 42psi at idle with the HBP
What kind of belt do you have on the pulley?
5-6psi is normal for the HBP... it would be 6-7psi in colder temps. If your boost gauge is reading 5psi with the stock pulley your stock gauge is reading incorrectly.

Step up to the HBP... it's worth it.

This might be a dumb question, but what color is the hbp? The kit I bought had two pulleys, one black and one a gold color. The black one was the bigger of the two pulleys and thats the one Im using, but the boost gauge is reading 5.5 to 6 lbs of boost.

You are using the HBP. Bigger alternator pulley = more boost.

Usually when people replace superchager pulleys they go to a smaller pulley because they are replacing the pulley on the blower shaft.
