a rough estimate of the power to weight ratio of a stock 03 cobra is 9.4 pounds per HP. in a stock FB with a stock 13brew its 9.02. thats without any mods on the 13b, and no one is going to swap a 13brew without going to an aftermarket ecu/fuel comp, full exhuast, and non-sequential turbos.



now theres more math to find out for sure if the fb would be an 03-04 cobra killer, but i dont want to take the time to do all of that.
