yeah thats true, i agree

I'm just curious, I don't think stock for stock the supra will pull on the cobra at any speed. I don't know about the 03+ cause I never drove one, but I know how v8's are from my LS1, and I still have gobs of power in the top-end... I fly from 110-120-130 as quickly as some cars go from 10-20-30. Unless the Cobra is totally different, which I don't think it is, it has power, period, top and bottom. And usually I thought that greater # of cylinders gives you a top speed advantage, but I might wrong and it might go to the boosters with the revs.

It does have Toyota reliability and slightly superior cornering abilities, but when it comes to the 1/4 I'd give the slight advantage to the Cobra. Not to mention the cost of modifications are significantly cheaper for the Cobra.

Either way they are both great cars and you coudlnt go wrong with either, its up to your preference really. I think the Supra is a better all trac car and highway runner.

But the Supra vs Mustang isnt the age old rivalry, thats strictly a Camero issue.

It's easier to squeeze power out of a 2JZ than a 03 Cobra please explain this to me?

well i can tell you this, a supra is faster than my car stock for stock with just exhaust and intake(saying that i was about equal with the speed of a supra if not slower) i have out run my friends moms 96 cobra on the freeway and i've raced a trans am ls1 on the freeway and won, by only 1 1/2 car lenghts but i won, shot by at about 140mph a supra is known for bieng a freeway beast, so as far as the older cobra's like your talking about most likely the supra is gonna run away from the cobra but a 03 cobra is faster than the others more hp, now there you have a good arguement.

see if you read i mentioned a cobra is faster than the supra, then he mentioned yeah in the 1320 but what about the freeway since its know for being mean in that category, then i said yeah thats true it is known to be a monster on the freeway. so you have a good arguement is the cobra faster than the supra on the freeway or at high speeds?

I think the main reasoning behind why which car has more acceleration on the top end would be rather looking at hp numbers, check out how their geared. Ive found some gearing numbers for both, I'm not positive their absolutely correct since I've found them on the net, but I'm sure their close. I'm using the 03' Cobra and the 98TT as examples.

03' Cobra:
1st Gear Ratio 2.66:1
2nd Gear 1.78:1
3rd 1.3:1
4th 1.1:1
5th 0.8:1
6th 0.63:1
Final Drive 3.55:1

98' Supra TT:
1st Gear Ratio 3.827:1
2nd Gear 2.36:1
3rd 1.685:1
4th 1.312:1
5th 1:1
6th 0.793:1
Final Drive 3.133:1

I hope this kinda explains things a little better. The six gear in the Cobra is so low its probably almost usless in the topend, which in turn, gives the Supra a much better advantage since it can actually use all of its 6th gear up top. Not to mention the final drive ratio is very high on the Cobra (another reason for it being very quick off the squat). I know the Cobra/Vette/Viper all share the T56 tranny, and the Vettes top gear its practically useless at high speeds. The Viper is probably the only one with enough torque to use it. The best way to figure out which one would be faster would be equip them with the same gearing (if possible).

Bottom line: Supra is geared for highspeeds, the Cobra is geared for acceleration off the go.

[youngvr4]

thing is the though gearing is lower, the cobra has 70 extra horses and 75lbs more tq, bu the supra weighs 200lbs less. but i've heard for every 100lbs if you add 10hp you stay even, you get me?

Horsepower : 390 hp @ 6000 rpm
Torque : 390 lb-ft @ 3500 rpm
Redline : unknown

Top speed : 155 mph(electronically limited)
0-60 mph : 4.7 sec.
0-¼ mile : 12.7 sec @ 110.1 mph
60-0 braking distance : 116 ft

Curb Weight : 3664 lbs(coupe)
Overall length : 183.5 in.
Wheelbase : 101.3 in.
Overall Width : 73.1 in.
Height : 52.6 in.

Ok, the numbers for the T56 are a little off.
Second, the Mustang may have a lower (numerically) sixth but the Supra has a lower Final drive, so it kind of evens out. And anyway highway racing is done pretty much in 4th and 5th... when R u honestly going to be in a race that is solely in 6th gear? As YoungVR4 has mentioned, by priginal point, the Cobra has HOW many more horses, so it really doesn't matter anyway, it is faster, period. There are no special cases where a supra is faster.
Young, when you say YOUR car, you mean your VR4, or your LS1?

Is the peak hp number your only reason for saying the Cobra is faster, or do you have anything solid to stand on?

[GDK]

I think people are a lil confused about the topic because the threadstarter meant 03 Cobras. I know this cause I know him personaly and we were talking about this on the phone. And yes, no matter what the gearing is on the Supra, the 03 Cobra just has too many ponys under the hood. But like I've said before a barely BPU Supra is a very Good match for a 03 Cobra. Any other stock Cobra will lose to a stock Supra on a roll, but hell, newer GT's with good drivers and tires can play with Supras in the 1/4 mile.

[Joseph1082]

Ok, since others have agreed with me, it looks like I AM standing on something solid. Ok, I don't have a 03 Cobra sitting on a dyno in my garage, but i'd assume that its peak HP is not just a fluke but that it has a steady climb toward it. It is Supercharged, not Turbo, so there is no lag, the boost rises steady w/ the RPMs because it is belt-driven. It also has 390ft*lb's of Torque, which I'd assume it makes somewhere in the middle, especially because of the Supercharger. I'd also have to say that it has a nice flat torque curve after that, maintaining that force, especially becasue Torque=HP somewhere in excess of 5000RPMs but before 6, I forget the exact number. My point was that saying this obviously less powerful car can hang with a much more powerful car is absurd! Thanks for the attack.

[LjasonL]

Obviously you completely missed the point.

My dad's truck has as much power and wayyy more torque than both, and is a good deal slower than a stock Civic Si. If you think it's faster because that number is bigger, you're missing out on the other like 75% of what makes a car fast. Saying "It's faster cuz it has 70 more hp", that is absurd.

So my question was, do you actually have any real evidence that a Cobra will pull away from a Supra from a rolling start, or are you basing this all off of the hp rating? I'm talking like a 70-120mph acceleration test ideally, something like that. Cuz you're sitting here acting like what you're saying is the God spoken truth, but you haven't really gave any evidence other than "cuz I say so", now have you?

BTW, why is this limited to straight line acceleration only? The Supra handles better too...

[Joseph1082]

Ok, but the truck weighs twice what the Civic weighs, speed = power/weight ration. The truck also makes a lot of Torque up front so it can tow etc. as opposed to the civic which makes whatever little power it does casue its redline is at 8400. Power is a function of Force, Distance, and time (Time is in the denominator, less is more, quicker is better) I expalined how I know the Cobra accelerates, not that it makes high peak HP for some other reason like towing. They are both race cars and so have similar powerbands, actually the Cobra's is better, NO LAG! Not that I have owned a Supra but after you debate the Supra people (who think that the Supra is God) and make them realize it isn't the fastest 1/4 car compared to american muscle, then they bring up the point it is faster on the Highway... WHO THE HELL MADE THAT ONE UP. It has the same power/torque curves whether racing from a stop or on the highway. As for gearing, the person who tried to prove it had Highway gearing actually proved that the gearing is somewhat similar... the Supra has faster high gears but the Cobra has a faster final drive gear so it even out. Oh, and I figure the Cobra is somewhat similar to my Camaro LS1 which I do own and drive and can tell you is a beast.

[Joseph1082]

Oh, as far as I know unless the 03 Cobra has Suspension upgrades from other mustangs the Supra will handle better. But so marginally it probably doesn't make a difference anyway.

hold it buddy, going of the statement 10hp make up for every 100lbs means the stang is more like 50hp ahead of the supra. example i've known of a supra taking a c5 vette down the highway, only by half a car length. vette at 350hp weighing less and having 30hp more than the supra still lost. what turbo lag are you speaking of? at high speeds like that there is no turbo lag its pretty much constant boost. hp isn't everything whats the power band like at high speeds and in 3rd 4th and 5th gear wich is more aero dynamic wich has better gearing if the supra's gearing is out doing the cobra in 3rd 4th and 5th then its pretty much a done deal. 3rd gear can take you to around 120mph alone.

i'm not saying your wrong i'm just saying there is alot more to speed then what you've mentioned. so don't go believing for a fact that your right.


btw i was speaking of my vr4. i don't have a ls1, but my dad has a c5 vette.

[LjasonL]

As far as powerband goes, which car has a higher redline? Higher redline means you can hold lower gears longer and put more torque to the wheels to ultimately go faster.

Look at the gear ratios. 3rd gear multiplied by final drive - Supra = 5.28 and Cobra = 4.62. 4th gear - Supra = 4.11 Cobra = 3.90. 5th gear - Supra = 3.13 Cobra = 2.8. 6th gear - Supra = 2.84 Cobra = 2.24. So you can see the Supra has more acceleration oriented gears in all of 3rd-6th than the Cobra, and it's a pretty big difference too, more than enough to make up for power.

I'm not even gonna try to look up cD or frontal area figures right now cuz I'm not really that interested

There is only a 3 mph difference in trap speeds as reported by Car and Driver, and the Supra is known for being much faster from a high speed roll than it is in the 1/4. The Cobra owners I know, on the other hand, say the car just isn't aerodynamic enough at high speeds and starts to lose some of it's steam. The Camaro guys I know say the same about their cars. Of course, these are guys who have ridden in a Supra so they know what to compare.

...You have actually ridden in a Supra, so that you have something to compare to when you say you car "is a beast", right? (which I'm not really sure how a Camaro came into the discussion in the 1st place )

So it comes back to, can you show some type of figures for the Supra and Cobra in a 80-150 mph run or something similar? I can't find anything like that, but all the evidence is pointing to that they're gonna be pretty close, which is what I 1st suggested.
