With anything smaller than a 3.2 pulley I would recommend that you install GT500 pumps.

if your not upgrading the injector get the GT500 pumps IMO, w/ the GT500 pump set up the 39s can flow like 48s with a proper tune

GT500 pumps. Instead of stressing a single pump, you'll be running dual pumps at a comfortable load. Also sets you up for future mods quite nicely.

Dont skimp on the fuel system ......get the GT500 dual pumps....you can be maxing out your stock pump anyway with the BAP so get the GT500 pumps and the duty cycle will decrease (thats a good thing)

Don't play around with the fuel supply...having just enough is not enough

I wouldn't go more than 500rwhp without internal work, first and foremost. Secondly, if you're going past the 450 rwhp mark, why not just be safe and go with the dual fuel pumps. You'll also need injectors. The blue 39s will be topped out about the same time as the fuel pump. When it comes to fuel, I would much rather be running a comfortable setup than be running everything at their maximum operating capacity. Finally, a 3.2 pulley will get you in the range of needing far more work than you have done, so I don't see the point in the 2.8.
