What size crank pulley should I use on my 03 cobra with a 2.8 upper with idler and where can I purchase it???

Id probably do a 2lb with the 2.8, anything more would be overspinning the eaton.

Metco's website, not sure what it is.

I'd stay with just the 2.8 upper and the stock crank pulley. Anything more will overspin your eaton and cause it to die and put off a lot of heat in the process. And you wont gain that much hp from going to a different lower.

i would go with a 2 or 4 pound but no more than that. and its not really worth it without a ported blower.

The blower is ported

got this off cobrabobs site and as for over spining the eaton i wouldnt go over 19,300 RPM
