Can a 2009 ZR1 run with todays nascar maybe a couple of laps?

My car is a stock C6Z (well, Killer Bee and tune, OE size Hoosiers). The car is my daily driver and I drive it to the track and back. I have stock suspension, but I set up a nice aggressive road course alignment (symetrical for turns in both directions).
I'm just a weekend HPDE driver and don't have any experience in a NASCAR Car of Tomorrow, so I just didn't feel comfortable at anything faster than 150 or 155 up on the banking. As you might be able to see in the video (and as was mentioned in that other thread) it's kinda bumpy up on the banking at Daytona and that can tend to unsettle the car a bit (I've heard it's smooth as silk at 'dega). I ran in both Comp mode and AH off completely and in Comp mode I could still see "Active Handling" lighting up in the DIC while bouncing around the banking, so the system was feeling some twitchiness of the rear end.
You can see the car gets to 160+ very quickly after coming out NASCAR T2 and onto the SuperStretch. If I didn't have to brake and go through the Bus Stop (that chicane on the back straight) I think it would easily be doing 180+ going into NASCAR T3. If the suspension were set up for it and you had some real racing slicks, you might be able to sustain that around the banking.
You can see when I come out of NASCAR T4 and hammer it that it gets to 175 by the start/finish line and I need to brake for the infield turns. If you could keep accelerating around the tri-oval I think it would easily be doing 185+ by NASCAR T1.
The ZR1 with way more HP than my car should be able to do a lot faster than I was going. The car definitely needs to have the suspension and alignment set up to get max speed on the banks, but if you set up the ZR1 and put race tires on it I think you could get NASCAR speeds. The CoT that NASCAR is running may put out 850 HP, but on the restrictor plate tracks like Daytona I think they only make 450-500 HP and take a couple laps to get up to speed and I think the ZR1 has a lot less drag. My car felt very solid and planted at 175, but as you get above that in a ZR1 the aero stuff should keep it very planted. There's a lot of downforce on the banking from the G-load developed while up there. Here's a picture of my right rear wheel well after the event:
So.....with all the power a ZR1 has, and the aero package it comes with, I think it still would need some serious suspension/alignment work and better tires to hang with the NASCAR CoT on a superspeedway.

wow thats an awesome vid! wish we had some of those type of events on the east coast!

Bob,
Was there a reason you were lugging the engine down to 3k RPM and not down shifting?
Can a 2009 ZR1 run with todays nascar maybe a couple of laps?
Yes - In 1994, I drove a Bush National Car at Daytona in the 24 hour. Top speed down the straight to start finish I was clocked at 205, something I believe the ZR! with its aerodynamics sitting on not big Goodyear Race Tires could match. Remember, NACAR's are steel bodied and sit on very thin tires. They are not the easiest cars to drive, say compared to a SCCA Trans Am for example. Best

You're in Delaware? How's this: In 2009 the National Corvette Museum will run HPDEs at VIR (June 29-30) and probably at NJMP Lightning (July 20-21). Feel free to register and bring your car. You will receive classroom instruction and instructors will be there to ride with you.
If you want to run at Pocono (using part of the Tri-Oval), there are several clubs that run HPDEs there.
Was there a reason you were lugging the engine down to 3k RPM and not down shifting?
Well....I'm a novice track driver and the car goes so friggin' fast that often I don't feel the need to go any faster. I ran in Comp mode or AH off - both of those modes turn TC off, and you have to be very careful bringing on the power, even at low rpm in 3rd.
Coming out of T3 (that tight right-hand 180 degree turn) at 50 or 55 in 3rd, I have to be very careful feathering in the throttle even at less than 3,000 rpm, so it's definitely not lugging!!! In traffic when going slow I quite often got down into 2nd, but needed to be VERY careful bringing in the throttle - even with Hoosier R6's.
The Z06 has a tremendously broad/flat torque curve. Take a look at the dyno sheet in this thread:
I've got the same setup as that car - HallTech Killer Bee and Jim's email tune, so my car is probably putting out similar power.
The ZR1 may need to have more rpm on it to keep the boost up for best power, but the Z06 is a pullin' beast at just about any rpm.
At interstate cruisin' speed I'm doing 1,400-1,500 rpm in the Z06. I've read that in a ZR1 you'll be doing more than 2,000 rpm at the same highway speed.
My car is my DD and I'm taking it easy on her, and being at an HPDE I'm just out having fun - if I were doing qualifying laps I'd keep the rpm up above 4,000. I've got a progressive shift light behind the steering wheel - the bottom light is set at 3,500 and they all blink the shift at 6,750 (they are blinking all the time in my video because of some harmonic with the 30 frames/sec of the video camera and the electrical system of the car).
The car blew away everything else in my run group, so I was able to just cruise and do 2:05/2:06 laps. I'm watching the Rolex 24 right now and see the GT class race cars are doing about 1:55 laps and it's still early in the race - I bet they'll settle down to 2:00 or more laps over the next few hours. If I really pushed it during the HPDE I'm sure I could easily have knocked off at least 5 seconds, but that starts to get really hard on the car.
So....getting about 4 thirty minute sessions per day over 3 days, I got a lot of track time. I drove quite hard some time, but was just cruising a lot of the time to keep from over stressing the car (or driving beyond my limits! ) and just didn't feel the need to keep the rpm above 4,500 or do 7,000 rpm redline shifts every lap.
It sure is neat watching the Rolex on the same course I just drove last month!!!
