94-95gt vs. 94-95 cobra.

[fastgtfairlane]

i know that the 94-95 gts were rated at 215hp and cobras at 240hp. how much more power was the cobra worth over the gt on the dyno stock for stock.

 

[Lightning Struck]

Im not sure but I would guess about 15rwhp

 

[Drew2o2]

More than that.

Key differences are.

Gt40 cylinder heads
1.7 ratio roller rockers
Better intake.
Possibly a better cam although i dont know if they had a different one.

 

[Slow95Cobra]

they did have a diffrent cam, but not that much better. not sure on a bone stock cobra.. but mine put down 221hp with a bassani O/R X and factoty catback. 190 pump and adj. regulator. k&n...3.55.. only performance mods for now. and i dont see any of those mods makin much more over stock. plus it has a few miles on the clock. so maybe someone can pop up with a gt along the same lines

 

[95Grandtouring5.0]

A stock gt prolly will put about like 180-190 on a dyno, and a cobra more along the lines of 220. The cobra was rated at 240, but was definetly under rated. Different heads, cam, intake, even the tranny was a bit more beefier. That car probably made about 260 hp at the motor

 

[Lightning Struck]

does ANYBODY have a link or something to a STOCK 94-95 Cobra dyno ??? ?

 

[quickstang_1994]

et wise they run the same or very close depending on driver

 

[OnyxCobra]

et wise they run the same or very close depending on driver

From what I've seen Cobras run low 14s and the GTs run high 14s low 15s. I don't have a dyno sheet but I heard they dyno around 220whp stock.

cobras have the cast iron gt-40 heads and cobra gt-40 intake, as for the cam a stock gt cam with 1.7 rockers is the same lift as for a cobra, i dont know if they use a slightly different cam for the cobras to get a longer duration or if it is just the same for a gt with 1.7s, cobras have 24# injectors as for the gt's have 19, the throttle body on a cobra is 60mm and the gt is the 58mm, and a lot of people think the mass air flows are bigger on a cobra but they are the exact same size thats on a gt, cobra come with a slightly better tuned computer and an rpm extender as for the gt's dont, and of course the cobra are all 5 speeds, no automatics, they come with 3.08 gears, gt's are 2.73's, thats about the basics for a cobra, as for power wise a stock cobra will put down about 220-225 to the tires and a standard gt will put down about 180-190 to the tires and an automatic gt will put down around 160-170, i have seen number a little better for a stock automatic but not to many and those numbers are for a good running car, something that wasnt beat up on and had great general care taken on them, my 94 gt automatic stock put down numbers in the low 160s and thats when the car had 30,000 miles on it, the average great runnimg cobra can run around a 14.3-14.5 1/4 and a gt can run around a 14.8-15.2 depending on automatic or 5speed

I have a 95 GT and I just bought a 94 cobra with 63,000 miles on it and completely stock. The GT has minor mods (k&n, under drive pulleys, aluminum drive shaft). The Cobra feels a little faster, but not extremely faster. I would say the 25 hp difference is about right, but I think it going to respond better to modifications.

 

[stang94X]

if i where you i would focus everything on the cobra and not even bother with the gt for a while, what are your plans for the cobra, you should actually ( my opinion ) take k&n cai, pulleys and aluminum driveshaft off the gt and put it on the cobra, especially that driveshaft, and if you have the money buy a set of good aluminim gt-40x heads to get rid of those cast iron gt-40 ones, get the lower intake ported, and a set of longtube headers and if you have money but not enough to buy aftermarket and want something a bit more snappier than get the shit ported out the stock gt40 heads and get the lower intake ported

 

[cobra30294]

your right I am moving the parts over to the cobra. The GT is up for sale or it will be used as a second for when the cobra is getting worked on. I dont know if the X heads are legal for smog in cali though. I hear a cam may be the way to go on this car and or heads (Sorry GT).

Living in Cali you'll never get the full benefit of a decent cam, and good heads. or even Longtube heards... :nonono:

 

[stang94X]

the X heads are 50 state legal, i have them and i passed Echeck with everything thats done to my car, well except for i had to put the cats back on

 

[stang94X]

in my first post i was mistaken on the gt cam versus the cobras, they are different, the stock GT cam is .442 valve lift with 1.59 rockers and is .472 with 1.7 roller rockers, and a stock cobra cam is .4787 with the stock 1.7 rockers and the duration is a little longer than the stock gt cam , if your worried about emmisions in Cali. and you want to cam your car i would just go with a E303 cam and 1.6 roller rockers and not worry about anything or an easier more cost effective way is to swap the 1.7 rockers with 1.72's, 1.72's will make a stock cobra to a .4853 valve lift and thats better than the B303 cam and since the cobra has a little longer duration it will be very similar to the B303 cam

Umm, you put down a pretty good explanation except for the fact, that NOT all gears in gt's were 2:73's. As for cobra's im not sure, as for gt's hell no 2:73's were not the only gears.

yes, some GT's had an option for 3.08's, i think it was only in 5speeds but i'm not sure

If your going to buy heads, they should not be ford. FOR GOD SAKE, IM SO SICK OF PEOPLE SAYING BUY GT40 HEADS!!!! For a bit more, you could get some heads that actually flow, Hell, AFR 165's will spank gt40s. I know personally, if i ask people for advise on something, and they even say GT40, your opinon is no longer even read.

 

[Shocker98GT]

True, the main reason GT-40s are popular is because they're plentiful and cheap, find an Explorer in a junkyard and voila

AFR 165s would be my choice for heads too. Trick Flow twisted wedge heads are good too, especially the CNC ported versions like those from Fox Lake, but I'm still a little iffy with the valve guides due to the rotated valve location.

are you talking about the stock cast irom gt40 heads or the aftermarket aluminum gt40X heads, cause the aftermarket gt40X heads out flow the AFR165's and when ported they flow better than the AFR185's, cause mine did
