'03 Cobra dyno #'s

Clungstang · Feb 25, 2004

Just wondering what the stock '03 Cobra's are dynoing at the wheels.

EvilEyez · Feb 25, 2004

Check out www.dynoperformance.com
I've read anywhere from 360-370rwhp stock. My baseline run on a Dyno jet was 396rwhp 387rwtq with a drop-in K&N and a Bassani Cat back. I dynoed at 409rwhp and 390rwtq with the installation of a Bassani O/R X pipe and densecharger Cai. Strap it down and let us Know........best of luck.

I've seen everything from as low as 345 RWHP to as high as 380 RWHP. The average is around 365 RWHP on a Dynojet.

See sig, my dyno was a Dynojet the Cobra had a little over 2k miles at the time. The only Mod was welded in magnapack mufflers.

P.S. Thanks U.M. I saw the thread when you posted a pic of the "Tick" wasnt ready for it..... spit my coffee through my nose and almost fell off my chair laughing

Your Welcome!

Normally the Tick is no laughing matter....but when you've had your motor yanked out of the car twice in less than 3000 miles, you just got to have a sense of humor about it!

See signature. Shes a real animal already broke the right half shaft with only 4300 miles

Friedchicken · Feb 25, 2004

At 5000mi, with stock catback and air filter- but with a bassani catted x-pipe and removed air silencer as the only changes, my car put down 396/415 SAE

It's pretty stout from the factory

grey03cobra · Feb 25, 2004

Bone stock (two days after I bought it) mine put down 372 rwhp and 377 rwtq

CobraTone · Feb 26, 2004

Bone stock with about 1000 miles mine put down 360 hp 350 tq on a dynojet, in florida with 85 degrees and very high humidity.

MUSTANGLANCE · Feb 26, 2004

If you read the article, they stated it was on a mustang dyno, thus the lower numbers. The guy who owns that particular Mach has posted over at SVTPerformance. He is running 10psi with an x-pipe, cat-back and I believe dynoed about 430rwhp on a dynojet. He ran an 11.9@120 with that set-up though I'm not sure of the details of the run (slicks, dr's, etc). A good centrifugal set-up is no joke especially on a 4.6 DOHC.

Yeah and he over heated and blew a head gasket or something not too long after that article was shot! At least that's what I read.

As far as the low dyno number lets ask Vic, what's the lowest bone stock RWHP number you've seen thus far on your SuperFlow dyno for an '03?

You know, it almost makes you wonder if the aftermarket is afraid of the terminators..
Sure, you could buy a mach for 24,000, then put 5,000 worth of blower on it, 1,000 worth of fuel system, 1,000 worth of tuning into it, and end up with 80 to 100 more hp than a stock cobra.{but have a crap bottom end just waiting to let go}
OR
You could buy a Cobra, and change the pulley and do a tune or chip.{500-1000 dollars and get that power {and more} fully forged..
Go figure..
I am just not one for a non-forged engine with boost added..

It doesn't cost $1000 for tuning or at least shouldn't. Not sure if injectors and intank or external fuel pump would cost a $1000 either. I say to each their own. A sc or turboed Mach is different and definitely a kick in the pants. A properly tuned car should hopefully last a while under moderate boost. Of course I don't have any experience with the 4.6 except for my 03 Cobra so I could just be talking out of my ass.

I think you're right on about the 03 Cobra though. It comes with a great foundation and making 450rwhp (safely) isn't that difficult at all. Once I started runnin 11-13lbs of boost on my old supercharged 95, mega tuning issues. I know also that motor was on borrowed time. I don't worry at all about my Cobra under its current boost and tune. Thats comforting

Here's a link to my dyno sheet from this Sat 2-28-03.
