About the Cobra R thing, I remember when R&T tested the Z06, Cobra R, and ACR Viper, they mentioned that the Cobra dynoed 385!
Anyone know if that's true? Were they really that underrated? Make sense to me when I think about it. The terminator Cobras dyno 360's or so, and most magazines comment that they're a little weaker in the mid - top range than the R.
I have seen in person twice and have read and heard all over the least those ls1 put down is 315rwhp with open manifolds, and the hood open so he is probally right the engine does produce around 370 the way it is(just less restricted). That would be a 60-65hp gain over the stats from just removing a part(y pipe). I haven't seen another car do such a thing.

I'm pretty sure that is crank hp, not wheel. Is that the same article where they only mustered like a 13.5 out of the Cobra R?
The Cobra R is rated at 385 at the crank; I don't know if they are underrated or not, so I dunno what one would put down at the wheels.
As for 315 being the least hp an LS1 will put down with open manifolds, that may or not be true. Completely stock (closed exhaust) they routinely put down 300-305 depending on the dyno, so eliminating the crappy flatworm Y-pipe and huge restrictive stock muffler should give a fairly decent power increase I would think. 10 hp sounds reasonable, I dunno about 15.
"The 2000 SVT Mustang Cobra R debuted as the fastest factory Mustang ever produced. Its SVT-developed, naturally aspirated 5.4-liter V8 produced 385 horsepower, good for 0-60 mph in 4.7 seconds, the quarter-mile in 13.2 and a 170-mph top speed. As a true, lightweight R-model, it also had track-capable brakes, able to make a full stop from 60 mph in just 127 feet. Like all SVT Cobra Rs before it, the 2000 R came stripped of any stock feature not needed for track use or that would add excess weight."
Basic Specs
Compression ratio: 9.60:1
Bore x stroke 90.2mm x 105.8mm
Displacement: 5.4 liter/330 cid
Horsepower: 385 hp @ 6250 rpm
Torque: 385 lbs.-ft. @ 4250 rpm
The 2000 R was also stripped of un-needed every-day crap. No rear seats, radio, AC, etc.
Hope this helps in anyway.
