lookin to do a pulley swap and was wondering what pulley combos and boosteveryone else is running on their 03 04 cobras.

if you are un ported a 2.76 upper, if you are ported a 2.93 upper and a 4# lower would be my recommendation.

I'm running a 2.8 upper unported and its good for 466 rwhp for me. I'm getting a Steigmeier Stage 5 port soon and I'll be running a 2.93 upper with it cuz I'll be road racing with it. Keeps the temps down for me running a lil bit bigger pulley.
