[QUOTE="swoosh_stang, post: 5463202, member: 46742"] Same reason people use stock numbers of 300 for the S197. I have seen and heard of many people dynoing 275 rwhp stock. If you figure 15% loss that is 320 crank, if you figure 10% loss it is 305. They were conservative on the S197 #'s also, the 99 cobra debacle taught Ford a lesson. If you figure the same percentage of conservativity for the 03/04 cobra it would be 415 crank HP, which is 375 whp (ish). That is pretty reasonable. [/QUOTE]
