does anyone know if its hard to switch the pulleyonan 04 cobra or if i should get a professional to do it.. and if so how much do they usually charge.. and if i can do myself how long does it usually take and do you know where i could get step by step instructions. thnxs

 

It is not hard, you will need a pulley puller from billet flow or pulley boys. It takes about 30 minutes. You will need a dyno tune after you do it and a better heat exchanger. www.svtperformance.com should have a step by step tutorial in their how to forum.

 

not hard at all, i did mine in m garage in less than an hour, judt get the puller tool.
