4lbs of boost isnt enough, thats not even worth getting supercharged :'( i wanted to see about 7lbs or 8lbs... where can i get a new pulley, besides from craig @ paradise

please reply asap!

ASP sells them and you will need a 3.75" to see that much boost but your problem is going to be you fuel system. 24lb injectors and a FMU will not cut it. You need 42lb injectors and trash the FMU. You will have to many fuel peaks and lows that you will be wasting the boost with anything over 5psi. The 190lph pump will not be good enough without a secondary pump but it is just cheaper to put in a 255lph and yes that 65lph difference is major that is like having a stock pump and a 190lph put together at 50psi. With aftermarket heads you trying to fill the chamber of a better flowing head so getting the 7-8psi will push the SN past max. rpm with the 3.75" but it is the only way your going to make it and you might get belt slip with a 6 rib and still not make the boost. Not trying to sound negative but been using the Paxton for years with great success but you need to understand the units limit.
