Smaller Pulley or Bigger Air Filter

[haze324]

Hey guys, wondering what's the better option here. I have a P1X on a 3.5 pulley putting out about 11 psi at 7500 rpm and making 650ish on 93. I don't race the car, its my weekend cruiser and I never ever shift that high when cruising around town. I'm curious for more power and driveablity cruising around town should I drop down to a 3.25 pulley that maxes the P1X max out at around 7400RPM or should I make/get something like MAK's old hurricane pipe with a bigger pipe and filter, or maybe a combo a 3.4 pulley + pipe/filter. Trying to get some more power in the the 4500-6500 range that I normally drive in. Just not sure what I'm giving up if anything by going with the smaller pulley or what would feel better.

The bigger inlet pipe and filter will make the overall system more efficient, but the majority of the gains will only be at high rpm. The pulley will give you more across the rpm range, but also require more sc drive torque and have higher charge temps.

Thanks for the input, that makes sense. Now I wonder if I should do both.
