Keep in mind these are all approximations considering i'm not really paying strict attention to my speed as opposed to the rpms but they should be close.

75 mph in 5th gear at 3000 rpms sounds about right, but starting at that rpm is shooting yourself in the foot, so imho it was either a bad driver or not a real cobra. Either way its a kill, and i'm not trying to knock it, but just giving my .02.
everythign you said is true. if its a 55-75 ill use 3rd, if its ne thing higher, 4th. I normaly never race into 5th gear, but i did hit 6th one day racing some roush thingy. i wasnt even going 150

Could have very well been a stock cobra vert.

OP has 4.10s....a cobra starting in 5th gear (or 4th) at 75 mph is going to be a dog with stock gearing.

AND, IMO, if it was an 03/04....he's lookin at some serious motor work if he keeps boostin' in 5th or 6th.

why are you assuming the cobra was starting in 5th or 4th with stock gearing? just curious as i might of missed something


and ill go ahead and say it, he wasnt racing you fully, or he woulda raped your face with you starting in 5th freaking gear going 70. but i wasnt there so idk

Why do people think 6th gives you extra mph? You can top it out in 5th, 6th is useless except for gas mileage. I can't even see a stock new edge getting 1 car put on it if the OP's car started in 5th. Something is definitely a miss...

im not sure why you say this, but once my 5th gear topped out, i shifted to 6th, and kept accelerating....

OP stated he was guessing that the cobra started in the same gear as he only swapped gears once too.


ALl of this is assuming as none of us know what the Cobra owner did (obviously).

My only point is, there are still people out there that dont' know that you shouldn't boost in 5th/6th in Cobra's. Given the OP's power isn't but ~25rwhp less, but his car has 4.10s and weighs probably ~200 pounds less...I'd say pulling .5-1 car IF both cars were in 5th and 6th is very possible. Weight and gearing are what did it.

but again, no one knows what that cobra did or had.

This has to be the dumbest thing I've ever heard. Who starts a race and lets themselves get beaten twice? What purpose does that serve? He was definitely "racing fully".

Not sure what could be dumber than this statement...

all im saying is if it was a termi, and IF he wanted to race you full blown, he would off put more cars then you can count on you if you put your car into 5th gear going ne thing below 120

That's possible. It's also possible that it was a Terminator and the driver had a bad day. It's also possible that it was a '99/'01 Cobra or a GT modified to look like a Terminator. I don't know. Whatever the case may be, I raced him twice and beat him both times. The fact that I won makes me think it wasn't a Terminator, but as other have pointed out in this thread, it's not out of the question.

hey man, don't let the haters take the wind outta your sails. you raced him, beat him, then asked him if he was a real cobra and he said yes. what more do you need? like some are saying he may have been a 99-01 cobra. especially if you didn't hear a whine.

I'll agree that I just don't see how he OP wrapped out 5th and needed 6th but if both drivers started in an equally crummy spot in thier rmp range(i.e. 5th gear at that speed), then its entirely possible that he beat the Cobra. You also know gears can change alot. Assuming they are both going 75 in 5th, (I don't know final gear ratios) but the cobra has stock gears, and the OP has 4:10's then he was likely at higher rpm and thus should have been better off when accelerating. Also keep in mind the cobras S/C if there was one also relies on rpm's to a degree, so if the cobra's rpms are low then the levels of boost he is generating are likely low. There are way too many unknowns here but remember anything can happen on the street.

No, a 03 Cobra can make full boost at 2,000rpms if it wanted to.

It's no problem. No offense taken.

I decided to replicate the conditions of the race on my way home from work tonight. I started at 75 MPH in 5th gear, and accelerated to 110 (roughly where I shifted into 6th during the race). I actually watched the RPMs this time - I shifted around 4200-4300 RPM. During the race, I wasn't really paying attention to the tach, I glanced at it right before I shifted and probably thought the needle was moving quicker than it actually was. Sorry for the confusion.

So you shifted at 4,200rpms into 6th gear and beat a Cobra?



Sorry, it was either a really slow GT or a V6. Any DOHC Cobra is going to pull on a bolt on LS1 shifting at 4,200rpms.
