03 cobra boost

[brian98gt]

i'm ready to start messing around with my 03 cobra and i want to go with a smaller pulley. i was wondering how much boost can the stock internals handle. i know the internals are forged, but there must be a limit.

03 cobra motors are tough, I have some friends at Strictly Performance that are running Kenne Bell blowers with 17psi and 100 shot of nitrous making 650-700hp at the wheels. Also just make sure you get a good safe tune.

i was thinking around 18-20 max. i already see about 13 psi with the 3.0 pulley and i want to go with the 2.8 wich should probably push about 15 psi. i will be adding an afco heat exchanger soon and i plan on getting the auxillary idler pulley kit and idlers from rpmoutlet.com onloy 400 for the 2.8 pulley, the pulley tool, a new belt, the auxillary tensioner, and 2 pulleys.
