underdrive pulleys

[Big T]

I have some bbk underdrive pulleys for my 03 cobra. Does anyone know where to get instructions to install them? The instructions that came with the pulleys suck.

I was not aware that anyone made underdrive pulleys for the '03.

That being said, those would be the LAST thing I would put on my Cobra. UNLESS, it's DOES NOT slow the water pump. Cooling is the utmost concern on the '03's. The stock cooling system is marginal at best, don't hinder it even more by slowing down the water pump.

Thanks for the info. That may be why I can't find instructions. The part is BBK 1559

That part number is for a GT or a 2001 Cobra. There are no underdrive pulleys for the 03-04. Except for the supercharger pulley's, of course.

yeah, underdrive :doubt:
i hope you mean over-drive...
you want the belt to spin faster if you want more HP on these cars cuz it'll spin the eaton faster ... which = more HP, but no warranty, obviously.
