RE: How underated are..
I remember that dum-dum with the super Bullitt. He was funny
. Blackonblack or something? 2000gt is right though, all modern day vehicles should be identical, especially when it comes to the engine specs.

people will argue that which you can, make a dyno read w/e you want.
and there was a big battle royal with the bullit v. gt. where some guy claimed he had a factory freak. and i believe it was 2000gt that said there are no such thing's due to the tolerance being so strict now a day's

I would think that would be closer to the actual HP rating. i would put money on it. now i just to find a bone stock mach and test it! my personal guess is that the mach actually put down 320-330hp. everyone know theres gonna be that one freak that dyno's ungodly high so that one doesnt count nor should the one that dynos like a 4 cyl.

That's true, but both cars can pulla2.0-2.160' in stock form pretty easily and run 12.8(SVT) and 13.1-13.3(Mach) with the same60'. The IRS doesn't become a problem for Cobras until they really want to launch it hard. The two cars are still within .4 tenths of one another. We know that the 310 hp rating is wrong. If we take the lower % of parasitic loss and said it was about 12%, that's a 37 hp loss to the wheels. The one Mach I saw dyno at 285rwhp would be a 322 crank HP car, according to a 12% loss and the 310hp factory rating.

your also forgetting that the cobra's have irs
you can slap slick's on a mach and drop at 5k. (yes you are at very high risk of failure)
but if you did the same to a cobra, the irs may go farther then the car down the track

the Machs? I've been seeing and hearing of several Machs getting anywhere from 275-290+rwhp.Ford's claim of 310hp definetly doesn't add up, but nobody has ever really stated how off Ford's numbers are.
For comparison's sake, lots of Machs are running 13.3 or quicker bone stock. 2003-04 Cobras are good for a steady 12.8, so if Machs are 3-4 tenths slower, that would translate roughly into a 30-40hp difference. Cobras are also under-rated at 390 hp, so would'nt that put us at 350+ hp or so? Any one have any idea....

i read some of that arguement, but i jsut cant see the bullit being that much faster on a drag track, it'll hook better b/c suspension but thats it. well the tolerances are tight , but the factory freak can happen and does. even if the tolerances say one thing the factory can say another to hype it or underrate it.

RE: How underated are..
I always figured the Bullitt was a little quicker at the track because of the suspension, and only because of the suspension. You would think that a throttle body and underdrive pullies would be good for more than 5hp though.

RE: How underated are..
you would think so. i dont think a lot of the 4.6 guys understand suspension mods and what they do. im not saying all of them are that way just a lot of them think more hp = better. the TB is the dual 57 isnt it? if so that just adds a little better torque curve.

RE: How underated are..
well the mach and the 01 cobra have differnt intake cams. the machs will produce more tq because of the differnt cams and i think the intakes manifolds are differnt too.
but if you take an 03 cobra and break it in for 1000 miles then start beating on it and take another 03 cobra and break it in for say 6000 miles then start beating on it. the 03 cobra that was broke in for 6000 will dyno more

same heads as the 03-04 cobra
intake cam of the navigator here are the specs on the machs:
CR : 10.0.1:1 (pg 66 MMFF August edition)
gears 3.55 mach (3.27 cobra)
.392" duration .050 liftof 196 (closer to the navigator intake cams)
.390" and 194 duration ( almost the same as the 99-01 cobra)
