Stock C5 compared to a Cobra?

I have a friend that is talking about getting a Mustang Cobra at about the same time that I plan on getting the C5. All I'm going to do is K&N and Corsa. So, I'm guessing about 375hp. The Cobra is factory with 390hp, I think. Now, I know that sometimes hp isn't everything. So, how would we compare in acceleration and handling. Keep in mind that Cobras have independent rear suspension and I think they weigh a little bit more. He plans on a pully upgrade, so, what do you think? Is he going to walk all over me?

Edit: Yep, He just told me they have a curb weight of 3665.

The 2004 Cobra has much better performance than past Mustangs. But the HP and Torque increase is not enough to make a stock Cobra smoke a stock C5. It would be close but the C5 would handle and pull just a bit better.

If he goes with a pully upgrade he might just have the performance to get you. You'd be hardpressed to get 375 with just an exhaust and K&N. But the Corvette always has the weight advantage. The Cobra is no slouch though, don't underestimate it.

You don't think I could get 25hp with this K&N (link) and Corsa?

They claim up to 16 with that filter, I think it is more along the lines of 6-8 HP tops. I have had friends dyno cars after adding exhaust and open elements and they gained in the neighborhood of 15HP. I just think that these companies over rate the HP ratings on these add ons.

true, or the conditions are "perfect".

anytime i read about advertised HP gain on any product, i cut that # in half.

Nope..sorry,had a K&N with cut lid and hollowed cats with zo6 cat back,and the car was no quiker or faster in the 1/4,i did knock-off a couple tenths with the halltech t-1 cobra (also replaces the stock accordian),and i could feel the car pulling harder in the mid and upper rpms.Added constant 2 mph on my trap speed too.

I would not be suprised if your friend is going to add a filter and exhaust to before you guy's race.
Don't use shitty gas and get your PCM in the low octane tables,or you will lose,otherwise i'll say you will nip him if you can drive good...run flats suck for traction.Even when some people (like me) say they can hook up decent on run flats,still not as good as non run flats.I have OEM zo6 tires now.
Good luck and video it if you can..

Pesonally, I have seen a well driven Cobra walk past a well driven C5 here......it's going to come down to driver skill until he starts modding it. Then it's C5. Get yourself some N20 and keep the playing field level!

I could get a 100 shot for when he trys to mess with me. That would get me at about 450hp and a 100 shot wouldn't be pushing the limits to much.

Also, We are both very good drivers. But, could the Cobra ever handle as well as a Z51 C5. I just don't know much about Cobras.

With just the filter and exhaust you will not be running 375HP. Now if you added long tube headers, mild cam, exhaust, intake, Z06 manifold and some good heads you'd be putting over 425HP to the wheels You'd smoke darn near anything on the road and would be pulling low 11's in the 1/4 if you could get traction.

Those are my plans anyway

On a road course the Z51 would handle better than a Cobra.

Ok, so, how much HP do you think I will get from the Dual cone K&Ns and Corsa exhaust?

15 total?

Also, hawaii-5-lo, I plan on getting 255/285 F1 GS-D3

At least I will always have him beat in terms of style.

Also, I don't think he'll be able to touch the C6 Z06.
