Haven't tracked it at all, but it's well known that other 03/04 Cobra's with this setup are in the 10s and 11s on street radials without NOS.
While I have no problems with your statement about Cobras putting down 700rwhp on race gas... I don't think it's really something possible without some more work other than blower and exhaust. If you look at the traps of Cobras running 10s and 11s, they're fairly low because of slicks or drag radials.
And from those traps, you're not looking at 700rwhp (that's mph of at least 140+) but rather ~600rwhp which is still a buttload. You also never mentioned the laundry list of supporting upgrades needed to get your Cobra up to 700whp. Show us a dyno sheet or datalog to prove that 850+bhp without pulling the head even for something as simple as cams. I have no trouble believing around 550whp though... but if you really are running over 600rwhp, I hope you're ready for an engine rebuild.
Even with all that being said, you probably still have the fastest car on here that is daily driven(?). What's the maximum gear limited speed of your Cobra?? hehehe...
Complete list of aftermarket parts:
Kenne Bell 2.4L blower @ ~20 PSI boost
KB Boost A Pump, KB Switch Chip
KB Cold Air intake w/ 12" conical filter, stock meter, and Kenne Bell "Big Oval" throttle body
KB Boost A Spark, Denso IT22 plugs
Siemens 55 lb. fuel injectors
Bassani headers, x pipe, and cat back exhaust (2.5")
Ram 900 clutch and pressure plate
An '03 with nothing more than a KB blower and cool air kit can break 600 HP at the wheels with stock throttle body, fuel, ignition, exhaust, tranny, etc. I haven't heard of anyone blowing up their stock Cobra to date with this setup, and some are pushing to the limit of the KB and running almost 30 psi boost and nearly 800 HP at the wheels with stock tranny and IRS! Not for a daily transport thank you.
Since this is my daily driver I try not to push it to hard, and with that kind of power, you don't have to push it very hard at all to waste your typical wanker. Not to mention gas costs. I still get close to the factory 16 mpg if I don't stand up on it...
Once I get an official dyno and diagnostics and know where my A/F and all that is, I'm going to take it out to the track, but until then it gets babied since I did most of the installs myself without the proper diagnostics along the way (just simple bolt on's and trust that the chip is correct...)
I haven't tried to top it out, I'm too much of a pvssy, not to mention there are alot of speed traps on the freeway here
EDIT: For the record, the 700 RWHP is only my estimate based on modifications and parts chosen based on the known performance of other cars with the same work done. I won't have a real number until I can find the time to drive it to CA to get an official tuning and log from Kenne Bell, but it's pretty safe to say it's in the ball park.
