Hi guys, just bought an 08 silverado 2500HD that has a mechanically driven fan. The truck is dog when it comes to accelleration and throttle response (feels like the parking brake is on all the time). I've got plans for certain mods like catback, air intake, etc. but was told one of the main reasons for the sluggishness is the mechanical fan instead of electric. Is it worth looking into a conversion to electric? If so, anyone know of any companies providing a kit for this truck? I was told that the Suburban, Avalanche, and other 6.0l Vortec motors have electric fans...can I simply put one of those from the dealer into this truck? Not sure if the radiators are the same even the motors are. Right now, there is so little room between the fan shroud and air intake pipe that I doubt anyone like KN or Volant will be able to get there air intake kits fitted on this truck as it is. Really want to dump the mech fan if possible!
