Why am I only making 5 lbs at 5,500 with a 10 lb pulley?

[SVTHorsnake]

this is bothering me, at first I thought it was just belt slip, but it's too consistent now, what's going on? I did make a mean 11 lbs but that was well past redline!:bash: I have to admit, it was pulling hard then...

Please HELP!

Any chance of a small leak that might only show up as boost increases?? I don't know. Check all the connections. Good luck.

deff. check over the motor for any leaks. check vacume lines too. did you add a boost guage? where did you "T" that off of. that could do it too.

Are you sure your boost gauge is working right? If so, I would make sure your air filter is clean and that your Bypass Valve is not stuck open. Slipping belt is usually the cause though.
