KB GT500 vs C6Z - 5/12/2008 8:49:09 AM

I was with a friend of mine of the way to autozone in his KB GT500 when we had a highway run-in with a C6Z. First of all, his cobra is 647 RWHP but I'm not sure of the tq numbers. The car is insanly fast...probably the fastest street car I have ever been in. I was expecting us to walk pretty hard on the Vette.

We ran from a 45 MPH roll. The Cobra jumped out maybe 1/3 of a car length and held it until 100 MPH then the Vette just walked by us. I could not believe what I was seeing. We ran 2 more times with the same results. We followed the Vette to the gas station to talk to the owner a little bit. The car was stock down to the air filter. I've ran a C6Z before in my car and it was pretty ugly. I knew they were fast cars but I didn't know they were THAT fast.

I'm seriously considering selling my car to pick up a used Z06 now. You don't really need to mod them at all.

LS7 > LS3????? Impossible.

Doesn't the Corvette weight like 900lbs less?

Something's fishy if he's putting 650 to the wheels. Most GT500s trap 113 to 115 stock with only about 425 to the wheels. Hard to believe another 225 WHP couldn't put him ahead of a bone stock Zo6. But anyway sounds like fun. You guys ever want to throw a neon in the mix give me a call.

I agree. A stock Z06 is on average 450 to the wheels. 200 more rwhp in the GT500 should be more than enough to take a stock Z06.

There you go. That Z06 had at least 50 rwhp more than a stock Z06 and the GT500 was making 640. Those races were neck and neck. Take 50 rwhp away from the Z and add 10 more to the GT500 and I see the GT500 walking away.

Are you in Tucson bro? I'll let you beat the crap out of my C6 if you want. ha ha

Ya, I thought it wasa bit strange too. I expected us to pull on him but we didn't. I have not seen the dyno sheet for the car but I don't know why he would lie about it.

Edit: How much would altitude come into play? It hurts FI cars more than NA cars doesnt it? We were damn near a mile high when we ran and he said he had his dyno tune when he was in CA at sea level.

Other way around, higher altitudes hurt NA cars more than FI.

well damn, there goes my theory. ha ha

Maybe he was on a different tune. I didn't ask after we raced. He was all butt hurt that he lost so I didnt want to put fuel on the fire. ha ha

The high-altitude performance of a turbocharged engine is significantly better. Because of the lower air pressure at high altitudes, the power loss of a naturally aspirated engine is considerable. In contrast, the performance of the turbine (Turbo) improves at altitude as a result of the greater pressure difference between the virtually constant pressure upstream of the turbine and the lower ambient pressure at outlet. The lower air density at the compressor inlet is largely equalized. Hence, the engine has barely any power loss.........Yes this is the second time this week I've used this and yes it is plagarized from a turbo sight.

me too, when they show the view from the vette why dont they show the times that the shelby pulled
on it?
and yes 600+ hp should walk that vette

well the aeroydinamics of the GT-500 are not the best, the faster it goes the greather the drag forces will be. In the other hand the vette is way more superior on aerodynamics and the drag forces will not slow it down as much as the GT-500.

My apologies, The GT500 was not on the 647 RWHP tune. I just got back from lunch with him. He said it was at around 540-560 RWHP at the time of the race. He only tuned it to 647hp for a weekend at the drag strip.

What rear end gears does his car have? I was under the impression that the vettes were basically geared for all out speed...this would also play in the vettes favor for an interstate speed run...
