I'm a bit confused about the HP output of this car:

Is it 390HP at the Crank?

or

390 HP at the wheels?

Also, with my mods and the newly ordered Nittos. How would I fair against a lightly modded one? Lightly meaning exhaust and maybe a pulley change?

only stock 03/04 cobra ive seen dyno was 366.3 rwhp/ 370.1 rwtq SAE dynojet.

GAME OVER

at the wheels

It is like ~365rwhp I think, maybe even more. I see you ran 12.7 on street tires, with that plus nittos that could go either way based on driving ability of a stock cobra but if he has exhaust/pulley/tires or anything like that you might be in trouble.

It's rated 390hp at the crank but just like the LS1 F-bodies many of the '03/'04 Cobras are under rated. Some have dyno'd as high as 380hp+ at the wheels (over 425 at the crank) but others have dyno'd as low as 330/340rwhp (rare)...the average is around 365rwhp I think.

You should fair well against a lightly modded one, might come down to driver skill.

With a few mods to a 03-04 Cobra they can put 400rwhp to the rear wheels easy.

Wow, the first three posts we all got in at the same time. I say your best bet is to practice launching/shifting and put those nittos to good use from a dig if you race a stock or lightly modded 03/04 Cobra.

your MPH is high enough to run with a modded cobra.

grab him from a dig and put those nittos to work

It depends on what he has done to the cobra. I know people that have not done much to a '03 cobra (just the RIGHT things) and are making 500RWHP, you gotta remember, they have a forged bottom end and that makes just about anything possable to do to these cars straight from the factory.


I vote this: If the guy has done the right things and can drive, You'll get owned.

if hes chipped and pulleyed, with your cam and stuff, it should be a heck of a race from a dig, i say driver wins it.....

384rwhp bone stock.

It's rated at 390hp at the crank though.

We dynoed one late last year. He had programming and exhaust and he put down ~430RW.

I saw a 03/04 Cobra at the track run a 11.87 @ 118.xx with a low 1.7 60ft on Nittos . His mods were programming, pulley for the blower, and exhaust. His only weight reduction was the back seats were out. Trapping 118 in a 3500-3700 pound car is strong!

We ran but he did not have enough to take me.


I think the cars are about equal. It will come down to the driver. Good luck.

Oh well... guess I'm going to be investing in some spray for added insurance.

I had no clue that those cars were that strong.

365 rwhp on average. From a dig, if you launch you will leave him behind. Remember that those Cobras suffer from horrible wheel hop with that IRS. Up top, you are looking at a different story. They really shine in the top end, and their power gear is 3rd. If he has a chip and pulley...things will get ugly. As for exhaust and intake, it is not un common for just those two things to put the car a 410 rwhp or more. With your times in the 1/4 yous should do about even with one though. The Eaton blowers on those cars are absolite heat machines, and in hot weather they run a little more sluggish.

Are you kidding me?? To attain those numbers an LS1 would need full exhaust, good size cam, and a great tune.

I saw someone else stating that the FBody's are underrated. He said that when they tested them they were closer to 340-350! I don't know, its the first I have heard.

On the dyno I think 290-320 rwhp is about right for the ls1

Doesn't the SVT Lightining have the same engine as the Cobra? The reason I ask is that I recently ran one from 70-110mph and beat him by 5-6 car lengths.
