Default 400RWHP 03/04 Cobra, What's it take?

Okay so I might just live off Ramen Noodles for the rest of my life and get myself an 03/04 Cobra. I was wondering what they dyno stock and what it takes to get them to 400RWHP... Anybody know?

uhhhh they dyno like 370ish RWHP stock....so id say intake and exhaust work and youd be there lol.

or you could just do a pulley swap and gain even more!

So some major underrating on their part? They are rated at like 390 BHP right? Also, whats the best option for dealing with the IRS? Get rid of it or build it up?

Best option is swap it out for a GT or Mach1 rear end..and they underrated them on purpose...400BHP is the insurance cutoff. Once you break 400BHP on your car the insurance goes WAY up. Ford is smart! woot <3 Ford!

the reason for underrating them is for insurance purposes, they actually need to be as afordable to insure as they are to buy. << bang for the buck wise.

I'm a noob, but doesn't it have 390 at the crank? so..20% less of 390 would be 312 at rwhp. Correct me if I'm wrong plz.

So....hmm lets see: I would probably do chip tuning, 3.73 gears, port/polished intake, complete exhaust, basic bolt ons i guess.

Cobras were intentionally underrated by Ford for insurance purposes. Dyno results have proven they produce around 360-370ish RWHP stock.

underrated mean that they give it a lower HP at the crank number than the car actually produces, so in all actuality, the car likely produces 400-410HP at the crank.
