Re: The engine has developed a knock
I'm only making about 5.5 psi boost and even then that's only at about 6k RPM and above.
Car description says you're running an underdrive pulley. If that's on the crank, then that could be a reason you're not getting more boost.
What jackshaft pulley are you running?
