Just wondering how much better these are compared to the stock eatons. Lets say you have a 03 cobra with 390 hp, what would you get with just a KB swap?

 

That depends on which KB blower you go with.

This is copied from the KenneBell.net website...

The best performance product available for the '03 Cobra. Just bolting it on at same 13 psi as Eaton increases power by 72HP. That's more than headers, exhaust, pre cats, x pipe, throttle body and mass air meter make - and there's plenty more supercharger potential power on tap.

 

how much psi can you use with a stock cobra? wouldnt that help to see how much more hp youd make?

 

well the stock motor's can handle anywhere from 700-800+rwhp (800+ being on the danger side)

depend's on what bolt on's you have etc.. i do know ported eaton's can make around mid 500's with your full bolt on's. i think eaton's are only good to around 17psi but i could be wrong

 

most of the kenne bell cobras i see are making low 600s. my friend was runnin 18lbs with a kenne bell and made 630.

 

yea seen kbs push 640s on 19psi

 

yea, no kiddin'
i think i'm gonna swap a kenne bell on that lost cobra once i find it
