So the alternator went on my 04 cobra again. 2 times in 2 years. Been doing some reading up on it and from what I understand it may be being over spun due to my lower larger crank pulley... To remedy this I see that metco and STEEDA make/sell a larger alternator pulley.

Before I go ahead and purchase this pulley I was wondering if anyone had any experience with this or has any input. The lower pulley was changed by previous owner so I don't even know what size the lower pulley is... As a result I don't know what size alternator pulley to buy. Does it even matter? As long as it's bigger it's better is my thinking.

Any input would be appreciated
