How much money to make 03/04 cobra have 500/550 horse/torque

[armyed]

I was wondering if anyone knew about how much it would cost to take a stock 03/04 cobra to be putting out 500-550 horsepower and torque. Going to be buying one in about 6 months and wanted to know how much ill be looking to spend. Ill be taking it to modular power house in Atlanta to get it done cause I dont trust myself to do most of it. If anyone here has done this either with the same place or any performance shop and is around 500 to 550 or more power let me know about how much everything cost with labor. Thanks everyone

Hey bro that sounds awesome..not to much money there but with the ported eaton how long are you in high boost before the heaton drops boost off. I was thinking maybe I could find a car that already has a KB on it thats not pushing really high boost and will hold it all the way through but it scares me when i see one on there and dont know how much boost the guy has pushed through the motor and if maybe theres any damage. Also was wondering whats a good amount of power that will do well against most other cars on the road but if still actually safe for a stock motor, not what they "can hold" but what they have held up to and still good for daily use. im hoping for anywhere from 500 to 600 would be golden if they are strong enough to hold up to that abuse and if not what I would need to do to get it to hold up to that and what kind of damage that would do to my wallet. Thanks again

A stock Cobra will do well against most cars on the road. I have a pulley, intake, exhaust, tune car and haven't pulled up next to anything that would stand a chance since I bought the car (month and 1/2 ago). And I'm only making 470s to the wheels.

I was thinking about just trying to find one that had a KB 2.2 on it but its going to be hard since I want that shadow grey color and hope I find one thats KB'ed. God knows as soon as I get it im going to catch the mod bug and spend a fortune doing stuff to it so hopefully I can find the color I want and buy it from someone who has already spent all the money on it but has to get rid of it. Cross my fingers But we will see I guess once I get it, So I guess if i threw 5000 into it I could very easily have a 500+ horse car?

But then you don't feel the natural progression...Just one big oomph and then your ready to upgrade that too to turbo!

Ummm...very much so. although if you spend close to that and are around 5000, you did something very wrong. on average, you're starting (stock) around 37X rwhp, so it shouldn't take $5 G's to make 125HP more.

 

[armyed]

well 5000 also goes to suspension a little and to stiffin the irs and everything else that goes into making everything else hold that much power so 5000 should be about right, yes if i dumped 5000 just into the motor of course i could get there very easy but i dont want to do that then have a car that have over 500 horse but the irs blew up. so I dont just want to make the dyno numbers better I want the supporting mods as well

very good thinking, you're well on your way to a rewarding relationship with your car. btw, welcome to the site.
