I'm looking for the best way to add some power to the 2001 Cobra I just picked up. I got this very nice condition convertible with just at 50k miles. It just has a borla exhaust and roush short shifter right now. It will practically be my daily driver. (Rain or snow I'll drive the truck, otherwise Ill be putting miles on the mustang) I'm not planning on doing anything to build the engine, so just pick up some extra power to make driving the county roads a little more fun. I won't ever be actually taking the car to the track or running it hard all the time. I think just a used blower and 4.10s would be perfect. Tune it conservatively to somewhere between 425-500 bhp (just somewhere reasonably safe for the internals). It may even actually help out my gas mileage with the 4.10s! Since I'm not looking for any huge power gains, what's the cheapest I could find a used supercharger to fit my '01. Or what do you guys think the estimated cost would be if I could find someone to trade with for an Eaton swap? I didn't know how much of that was really going on anymore now that the cars are getting up over 15 years old! I would consider going N/A, but I figured if I was wanting around 450, that would be a more expensive route. This is just my daily driver so I'm not looking to spend a ton of money. I know this subject has been well discussed for the 01's, but all the information I have found has been fairly dated. So I was looking for a better, more current, cost estimate and what everyone's opinions were of the options today. Thoughts?
