01 GT Vs. cobra

[mattpe]

I own an 01 GT and i was wondering what info or websites ppl could give me to compare builind this car to building a cobra....

I am looking to ideally get about 400 -450 at the wheels

and some ppl i talk to say that if i buy a cobra and build it im just going to take off the cobra parts and replace them...

they say its better and more cost effective to put a turob or a supercharger on my GT and build it.


any info would be great thanks

ok well you have to consider this, your gt has a sohc 2v engine, the cobra has a 4v dohc engine. if you want your engine to be as badass as a cobras your going to have to convert it to a dohc 4v. but id say youd probably save money by just sticking with your gt and building on it, the other thing to consider though is that your car has a solid axle, the cobra has IRS, if you want to be superfast through corners your going to be at a big dissadvantage right off the bat. but the solid axle is better fot straight line raceing. you can buy suspension upgrades though and make your car handle really well with that solid axle. ive heard the 5-link upgrade is decent but not sure on that one.

Lets not forget those insides. I'm no expert but I doubt the engine and drive-line from an '01 GT can take 1000 horsepower.

Ok well 01 GT motor vs 03-04 Cobra motor: 450hp at the rear wheels

The people you talk to don't know shit.... you don't even have to take off a cam cover on an 03-04 Cobra motor to make a 1000hp so you definetly wouldn't have to to make 450RWHP. You can make that wit simple bolts on like full exhuast, CAI, smaller blower pulley and a good tune. If you want to start making 500RWHP you need to start thinking about a bigger FI set-up wether it be a Kenne Bell, A centrifugal S/C, or turbo's. Bottom line is the 03-04 Cobra long block is 20times what the 2V GT long block is. But it really may be of no use to you...

99-04 GT motor you can also make 450RWHP but your gonna need to buy a liquid or air-cooled S/C set-up to make low 400's. Then if you want to make the other 50hp your gonna need full exhuast and prob some intake stuff too.

ok so heres my thought.......

a stock 03 cobra is 390 at the crank so figure roughly 315 at the wheels
i dynoed my car with a full flowmaster exhaust and i put 245 to the wheels

also my car is payed off.....so im thinking
i have to come up w roughly 60 - 70 HP to make what a stock cobra makes......

i am thinking

stand alone fuel management system
Bigger injectors
fuel pump
T4 turbo
fron mount intercooler

run about 10 psi

i should easily make up the difference if not get more and then i dont have a bigger car payment either....

what you guys think

[mattpe]

also....

can anyone get me a price on a kenne bell for an 03 cobra??

Bone stock 03's typically dyno 370-380, you're a ways off champ.

That might make up the difference, but then you have a car with weak powdered metal rods, and thin ringlands that are ready to let go at a moments notice at 400+ RWHP. You can pick up an 03 in the lower 20's if you look hard enough now. An 03 with full exhaust, CAI, pullies, and a tune will make more than 450 RWHP with stone cold reliability. Get tired of that? Drop a little over 3K for an FRPP/Whipple twin screw and a bit more on bigger injectors and dual focus pumps and you will have a reliable 600 RWHP car. If you try and do that with a 2V car you need ported heads, cams, different intake manifold, a built shortblock, etc, etc, etc.

how do u figure? there rated for 390 @ the crank?
add around 15 -20 percent drivetrain loss....
so around 320 -330? i wasnt to far off!

[stang805]

the stock '03 cobra with a power chip and overdrive pully on the blower will make 450 rwhp

I don't think Ford does it at the crank. I think Ford does their horsepower test after the transmission so the drivetrain loss won't be as much as you would think. I think the highest dyno I've seen was done by 5.0 when they put it up against the '00 Cobra R. I think they got around 360 rwhp.

Heard of a car being underrated?

Just like the LS1 F-bodies were "rated" at 325 HP but were putting down anywhere from about 290 on a weak automatic car to as much as 310 RWHP bone stock.

405 RWHP 370 RWTQ, BONE STOCK 03 with a K&N FIPK

432 RWHP 400 RWTQ, 03 with stock pully, CAI, catback, and a tune

I'd find more but i'm too lazy and SVTperformance's search is down.

Tip: If you don't even know that 03/04's are underrated, don't worry about trying to build a 450 RWHP car.

thats why im researching u jack ass

sorry if i asked for help....
i know more about other cars and if u needed help about them or had ?'s i would help u i WOULD not critize u!~
