What was the supercharger that came stock on these? I thought it was KB but someone said it was Eaton? Or is this the same thing with just a different name? Also, which one performs better? Just curious as to what the differences are.

 

The Eaton is stock.

It's limitations are around 500RWHP with some porting.

The KB is a lot more effecient of a SC.

 

so some cobras have KB and some have Eaton superchargers ??

 

some also have a whipple or a turbo or whatever other charger they can think of but STOCK terminators came with a eaton m-112 i believe but like dan said a kb is ALOT more effecient than a eaton for one the boost level is greater i believe they run cooler also however it really makes no sense to even look into one unless you plan 500-550 rwhp because anything less than that can be achieved with the stock eaton with some porting, pulley swap etc.

 

03-04 Cobras come stock with an Eaton M-112 S/C. The Kenne Bell and Whipple S/C are aftermarket ones. M-112 comes from the S/C adding about 112 CI to the 281 engine.

 

The Eaton S/C is good for 525-535rwhp without nitrous with a port job. Depends on how much boost you're running. 16-17 lbs. max is recommended but some push 18-19 lbs. If you're looking for more than 520rwhp I'd recommend the Whipple or 2.6 Kenne Bell. The Kenne Bell 2.2 and 2.4 are discontinued.
