I'm not really even sure what a Rouch(sp?) Mustang Cobra has.

Monster, now w/ Rice

a stage II is just a body kit and a side exhaust

i forget what the stages are after that

is way faster than the s4, especially on the highway. Like 320 HP stock, and if roush does anything to it, its more.

Since the current Cobra is 390HP supercharged from the factory.

I'd be more worried about a plain looking older style 5.0L Mustang. With a simple Vortech supercharger the car could easily have 375HP. A '99 Vortech supercharged Cobra can push 490HP.<ul><li><a href="http://www.roushperf.com/">http://www.roushperf.com/</a</li></ul>

basic on mods prob ~420 hp, very fast car.

I have Stage II+ now, but he sold his Roush. I'd still say it was faster than Stage II+. For reference, his was a 2001 Stage III - 360HP and 375 torque.

But, almost all Roushes you see on the road have no engine modifications, they are just GT's with body kits, wheels, etc. There is no Roush Cobra, they are all built off GT's. However that may change with the new Cobra...
