Hello All,

I'm thinking about installing a roushcharger on my 07 GT. I already have a set of bbk's SFI underdrive pulleys on the car and I was wondering if anyone knew if I could use them with the roushcharger or if I will have to reinstall the stock UD pulleys? Tried contacting Roush a couple of weeks ago, but got no response.

Thanks

You don't want underdrive pulleys on a blowr application(Centrifugal or roots) it slows the blower pulley down and you make less boost. Bigger crank pulley and smaller blower speed the blower up making more boost.
