Mine also hits high 7's @91-93 in the 1/8th with street tires and good launch and 1.9 60 ft so I don't mind if it makes less boost I just really don't want to pay $1200 for the same result
Who will sell me a used C3 pulley???
I doubt you'll find one for sale. I dont understand why a company like Needswings or Eurocharged dont start producing them there obviously popular and would sell.
On another note why dont you just get your wife's stock supercharger pulley machined down to 65mm?
