98s/c cobra

Okay. This is what I have before everyone calls bs on this. I have a 98 cobra with a vortech s-trim,full exhaust, 4.10s, diamond pistons, manley h beam rods, and some suspension. Put down 482 rwhp and 406 trq. This happened last week and I've just been too busy to post. Last week a couple days in a row I've been taking the car out because it is getting cold and the weather is going to get nasty so I might as well when I can. So I'm crusing and I see about 1/2 mile ahead of me is some vette tail lights. So I speed up to try and catch up to it thinking it is just going to be some C5 vette and I'm going to rape it. Well finally when I catch up to it to my surprise it is a brand new Z06! I'm like no f ing way. I drop it in 2nd at about 45 which is perfect for me and he wants nothing to do with me.

We come to a light and there is one car in front of me and there is two cars in front of him. The light turns green and I wait and wait and finally he is next to me. I keep pace with him and I just yell at him, because I knew he would hear me because his windows were down, "Please race me!!". As soon as I said that he took off. Instantly he was about 2 and half cars in front of me. So I punch it and I'm reeling him in to my surprise. By the end of the race my front bumper was at his rear bumper. He had to stop because we caught up to the cars that were in front of us. I was so pissed and I knew he wouldn't race me again so I just went on. Those things are fast. I just wish that we would of gone from a honk or he wouldn't of jumped me because maybe I would of had him.

Put down 482 rwhp and 406 trq

The Z06's put down in the 500-530's I beleive. It was a good run no doubt, but im wondering if the guy bothered to downshift or was even giving it all its got. I mean he does have a hp advantage and weight advantage on you

Modded yes stock they put down around 440-450rwhp. The 98 cobras are pretty light. Good kill!

98s/c cobra

I thought it was 500 flywheel, and 480rwhp?

M3Corvette

98s/c, it won't happen. You would have a good start and lower speed run, but the C6 Z will pull away after that. A friend of mine has a 98 also with almost the same setup as yours. He put down 46x RWHP and my stock Z pulled him. They put down about 460 RWHP and 450 RWTQ stock.

on average, they make 440-460rwhp stock...

if they went from a low 45roll like he said earlier, i could see his '98 SVT running with it until they hit traffic... The Z would definately pull away after 100mph.... Besides, his Cobra has a 20-30hp advantage and it weighs in about 3200lbs....

M3Corvette

Yes, mine put down 457 RWHP and 449 RWTQ with about 300 to 400 miles on the clock. It really pulls in 3rd gear on.

67maro

You gotta factor in a driver mod and a car that might not of been broke in yet.

M3Corvette

Most other guys I know with the new C6 Z won't run them and modding is out of the question. Makes you wonder why some poeple will buy the car.

98s/c cobra

Because they are bad ***.

M3Corvette

Hell yah, but we all always want more.

I am with Scott on this one. I dont doubt your win, at all. But, you beat the driver, not the car. It will take a lot more than 482 rwhp for a Mustang to hang with a properly driven C6 Z06 from a 45 roll. Trust me, I have raced MANY..

02ZOh6

I had a vortech'd 97 with LT's and 4:10's that put down 455/385 and ran 11.70's@122. I can see this being a decent race. My car weighed 34XXlbs w/o me in it if I recall correctly.

M3Corvette

LOL You bully you!

Fadi

Who, me?? Nah...

ponygt65

I agree....

Why is everyone racing dyno numbers here? A properly set up properly driven 475hp mustang is good for bottom 11s if not faster. Mustangs are a different beast than the LS1 cars and some people are just smarter and know how to set up a car to go fast instead of making HP numbers.

300bhp/ton

Considering the LS7 is hand assembled I would think they are actually very consistent on what they put down stock. Provided they are always corrected to SAE. The difference in numbers is due to:

1. Lack of correction (STD numbers instead)
2. Different Dyno types. A Mustang Dyno will typically show a lower figure than a Dynojet Dyno even if its the exact same car.

So the implication that they raced a less powerful LS7 C6 Z06 would probably be wishful thinking.

First off you don't know the HP difference as we don't know what type of dyno and what correction factors the S/C Cobra was dyno'd on. It could well be making 20-30HP less than the Z06.

Plus with a blower installed oon the Cobra the Z06 will still have a good weight advantage and a MASSIVE torque advantage espcially in the lower rpms, as a centrifugal blower also does nothing for the low end torque curve.

Lastly and most suspiciously is how the race went. I don't doubt the outcome, just the resaonsing behind it.

This is because they didn't start racing at the same time:
this means that there must have been 1.5-2 seconds lag before the Cobra accelarated maybe more. So this means even if the Cobra was as quick they would still loose ground. To keep pace they would need to out accelarate the Z06 by a lot. Example:

1/4 mile race from a dig, for all intensive purposes both drivers and traction eqaul. Car 1 is a 14.0 second car and Car 2 is a 12.0 second car 100% cosistant.

Both cars leave at the same time, Car 2 will reach the finish 2 seconds sooner. If they race again and Car 2 waits for 2 seconds at the start they will out accelarate Car 1 but only cross the finish line at the same time. To actually beat the slower after giving them a head start they need to be considerably faster.

If the Z06 was being driven as fast as possible the Cobra would need to be trapping in near 130mph to not only halt the pull of the Z06 but to then real it in, espcially in such a short time scale.

Logical however would suggest that as the Z06 driver evidently didn't really want to race and had no real interest in the Cobra then when someone shouted at them "Please Race Me!" they simply floored it in the gear they where in, which probably wasn't optimum for roll racing at that speed. Hence the Cobra was able to real it in even though they only raced for a short distance.

unit213

Agreed. I know some cars that run 10's with just over 400rwhp.

RED04Z06

^^^Agreed also. Get a good suspension notchback mustang making about 425rwhp and you can have yourself a 10.9 car or faster.
