Has anyone heard of puting a smaller crank pulley on to lower the boost range on a B16?

 

never heard of anyone doing it on purpose but it would work. If you have a UD pulley on, boost will be lower. But why?

 

it's too fast for him

 

My supercharger is pulling 9psi on the stock pulley and I wanted to turn it down till i could afford hondata. it detonates so i'm nott driving it till i cure the detonation problem. it was suggested by one of the tech guys at Jackson.

a stock JRSC setup should not produce 9 psi without upgraded pulley(s). You may have improper cam adjustments or a restrictive exhuast system. But to further verify you question, my buddy accidenlt left a UD crank pulley on his car when he installed a JRSC and boost was lower than promised so a UD crank will drop boost. If you plan to get tuned in the near future, save yourself some work and just zip tie the SC bypass valve open and run NA.
