I have no problem with admitting the cobra's put down some power. The way I see it, the cars are really in two different leagues. The C5 is a much more refined overall car than the cobra. When I hear cobra, i think to the mustang/F-body wars. It's like apples to oranges to me. Not to mention the fact we're comparing a superchaged motor vs. a non-supercharged motor. Let me put a charger on my Z06 then we can compare apples to apples. I race a few cobras in the 1/8 mi. Some I beat & some I don't. I have just bolt ons & I went round & round with this one guy in a cobra. He had slicks, I had drag radials. He wouldn't say what he had done, but it wasn't stock. He ran mostly 7.8s & 7.9s while I ran mostly 7.9s & 8.0s. All I know is if I was running a supecharger, I'd be pissed if I wasn't kicking a lot of other cars azz at the track. Scott

 

When I bought my 00 coupe the 03 cobra was one of my other choices. But the cobra weighs 3800 pounds. And if you want the top down your looking at a 4000 pound car. Also the cobra rear isn't as strong as a c5 rear. They blow the rears all day at the track. And that factory cluth won't take 400 plus RWHP for to much longer. And the depreciation on a mustang brand new invoice is 33k well you can buy a used cobra now for 22k. You just lost 11k and your lossing taxes you just bad on 33k.

 

I got toasted by one at the track on the last day open. He had a Whipple twin-screw putting down ~600rwhp. He was running in the 10's with CCW's and ET streets to my Pilot Sports I ran a mid 12 @ 117mph, respectable but I got smoked nontheless. My car still LOOKED faster though.

 

Cobras=dyno queens. Nuff said.

 

What about Stock MN6 C5 coupe vs CAI/Exhaust Cobra? You guys put them down alot, but I have seen many videos at the track and street where Cobras spank C5s

 

If it were my Cobra I certainly wouldn't need to make excuses for the kill. Would I care about the rear, the clutch, the depreciation? No I wouldn't. I'd have money left over to fix whatever broke. Same as my Trans Am. I loved that car immensly and was quick to overlook any faults especially when price was considered. For the extra $$ I would expect the vette to have more updated and sophisticated drivetrain parts. If I ran 10's in a stang and you didn't, then you may need to make excuses in order to justify why your vette is better. As to the supercharger, well if Ford put one in and the car cost $33K that's relevant. If the Ford driver then spent the additional money that the C5 driver will spend on a supercharger the Ford would be that much faster. I don't think there is a winner here. I love my vette but if blown away by a Stang, I need to make the excuses. If I think that its enough solace just to own a vette when the other guy doesn't well then o.k. great but the I don't think the stang driver putting down 10's at the track wished that he had my vette instead. Just my .02

 

not at my track. BUT to use your info... what are "they" spanking... totally stock C5's ?

 

Sorry...let me clarify, I meant to say a CAI/Exhaust C5 MN6 vs CAI/Exhaust Cobra...who would win? Is there a clear winner? So close, that it comes down to Driver?

 

I can really tell what forum I am on!

GONE BUT NOT FORGOTTEN!

 

I didn't watch the show, but they usually use a Dyno Jet, which if you compare to a Mustang Dyno typically give a higher number.

Both are great cars, but remember why the Cobra has a blower.... It needs it!

 

I felt I needed to respond to this thread since I've done plenty of research on the 03/04 Cobras (aka. "Terminator") and know our cars, too. First of, terminators aren't dyno queens !! A stock cobra is a fierce car, and my stock C5 gave all it could against one but it was beaten. It was CLOSE but a stock C5 is slower than a stock terminator. Sorry, fellas. It's true. Normally a stock cobra will run a 13 sec 1/4, and a normal stock C5 will run a 13.3 or so. This is paper filter, runflats, COMPLETELY SHOWROOM STOCK.

Now when you start modding both cars, then things get really bad. The dollar/HP is in favor of the cobra hands down. $1500 dollars for a pulley, cold air intake, exhaust, and a tune and you're pushing 430-450rwhp. For an LS1 to get to 400-425rwhp (which is what it would take to keep up with a 430-450rwhp terminator), it will take at least $4500. For a LS6 to get 400rwhp, it would take at least $2500.

"Ok, so those figures are fine but I can throw some nitrous on my LS1 and tip the dollar/hp in my favor." That's probably your best bet to level out the dollar/hp argument for an LS1. But know that a terminator responds well to a terminator, too!!

I still laugh at the statement, "I can throw a supercharger on a vette and it's game over!" Uhm, the terminator can upgrade it's supercharger and it's still game over for the LS1/LS6.

I still don't know where the "cobra's are dyno queens" statement originated from, but that's just BS. There are some really fast ones out there on the track. It's funny when I see people say they "saw 3 cobras at the track and they ran horrible 13.xx or 14.xx ETs". Well, most of the corvettes I see at the track run crappy times, too.

"So who's side are you on, anyway?!?" All of my comparisons were straight line acceleration, so when it comes to auto-x or road racing the terminator is "obselete technology." Hands down!

To sum it up, all I'm saying is there are OTHER fast cars out there than corvettes, guys. Ford is copying what's already been done with the T-Type/Grand national and supra. When a car comes from the factory with forced induction, it doesn't take much to turn up the boost and get some crazy power out of it.

At the end of the day it comes down to what you're going to be happy making your insurance payment on, though. I've got a built vette in my garage so I've made my choice. However, I wouldn't mind having a terminator or supra next to it one day. Give credit where it's due and stop making excuses!

 

Gee, a forced induction car picked up more horsepower per mod than a NA car *gasp!*

 

cobra hands down. cai/exhaust terminators are z06 territory.

That's another thing here guys. We're talking about a 03/04 cobra's... don't bring the other cobras in this thread becuase they aren't in the same league as a terminator.

 

but I was responding (originally) to Z06 Corvettes and not the coupe.

At my local track - bone stock Cobras only get to the lower 13's. It takes mods to even approach the high 12's.

Maybe the case is that the car is so overpowered - it takes a special born-with dexterity to get the most out of it... and I'm just not seeing it at my local dragstrip

 

Amen, I have seen (2) 03/04 cobras split and blow a chunk of the differential plate and subsequently all their gear oil right onto the launch line.
Talk about pissed the anouncer was saying they were thinking about banning the cobras unless they has some kind of aftermarket differential cover on the car. Nothing like an hour down time while they clean the track!!

 

Pretty clueless on terminator's are we? Does that look like a Supra's dyno graph?



I couldn't find a Twin Screw dyno graph

 

Wow, cant beleave Im on a this board and seeing this topic, LOL.
First off, having built and raced mustangs my whole life I was just in the situation of choosing either a used c5/z06 or an 03 cobra.
After weighing all the goods/bads the vette won hands down. We decided on a convertable silver/blacktop/black leather c5 and it was a great choice. Keep in mind, I have been a ford guy my whole life this is coming from me. For the money we were looking to spend, we got so much more from the vette. Had our only goal been to go fast, cobra would be sitting beside the supra right now.
There is much more to a car than power. To name a few:
Looks, hands down winner is the vette. Cobra looks just like every other v6 out there to the average person.
Exclusivity:vette, see number one.
Depreciation: vette easily wins this one. And, for the price of a nice vert, we could have picked up a z06, but we wernt in it for the power
The biggest part of our decision was due to the looks of it I want lie. You just dont get much bang for the buck in the looks department w/ the cobra, IMO.
Now, if i want to go have some fun on the street, I drive the supra. If I want to pimp on the street, Ill take the vette.

 

You need to drive a Z06 my friend, now there's an impressive motor! Seriously if you like Vettes and are looking for some more fun go test drive a Z06...I think you will like it. There is an amazing difference in performance between the LS1 and the LS6...no comparison, IMO!

I owned a 98 Cobra which I sold in order to purchase my Z06. Of course the 98 was not supercharged, but still a very impressive motor...handbuilt, etc. I did manage to surprise a few Vettes with that car and it was a stock motor, but holy horsepower, Batman, this Z06 is one fun son-of-a-gun!

Give it a try.

 

[QUOTE=Mike Mercury]I see stock Cobras at our local 1/4 track - and they don't beat stock Z06's.

Or lightly modded FRC's with DR's

Tim check out the PERF RESULTS section. Just re-dyno'd after the LS6 intake swap and posted the results. See ya...

 

will do Barry !

did you have any AFR adjustments made ?
