Las Vegas Pre-race Race Thread

oh ok, so I guess they could also be taping up, like a mock qualifying run. They are a long ways from a track record. 190.456. Glad I am not a driver...that could get me fined 25 thou.

I would imagine that the cars are being run in race mode, not qualifying trim. This is a test session, why mock-up a q'ing run when you don't know how the car is going to handle. There is another practice tomorrow--- I bet we see q'ing trim, then.

Yeah, the fastest are only a mile an hour off now. Five are running 189, record is 190.4
 
I noticed Harvick was significantly faster than everyone else in both sessions over 10 consecutive laps.
 
VEGAS

Where the true nature of the Gen6 Car will rear it's ugly aero-dependant head.

While the progressive banking may mitigate this trait to some degree, I am anticipating a Parade.

Still will be FAR better than the clusterfrak that was Daytona!!

Pretty brisk out here.
Skies turned dark so we scooted out to the parking lot to fire up the BBQ. Burgers, dogs, tater salad and beverages.
Scored me a David Pearson autographed '69 Talladega Torino :D
Maybe they'll get this track dried out, who knows...
 
The rain is going to let up, but will NASCAR even give a damn? I mean, they left the dryer in Charlotte.

How much more time does Goodyear need? Seems like there's a new tire everytime we turn around. They don't seem to be getting better. Yes I do remember the debacle at Indy.

I don't recall as many tire failures with the old bias ply tires. Seems to me that pre-COT tire failures weren't the problem they are today.

Pre-CoT cars weighed about 1,000 pounds less. There is no way to have a racey tire without lots of blowouts.

If they knew they wouldn't be able to transport it to most tracks, why did they hype it up so much? They had a big article on NASCAR.com complete with an animated video detailing how the new drying process works...sheesh. All talk, no game.

Unless they put the right size tires(bigger) on the cars?Like they were supposed to be working on for the last couple years? But I'm betting that's no more.Since we haven't heard anything about that for a while?

Since the frame would have to change to go any larger, I doubt they will do it now. Maybe they were smart enough to build in the well space this time? Nah,....

These cars are already under-tired. Thinner tires would just heat up faster. A larger rim size would give more cooling to the wheel but teams would figure out how to fill the inside of the wheel with larger brakes.

Maybe NASCAR needs to mandate rotor size like they do spring size. A smaller rotor woukld have less stopping power but would generate less heat, therefore resulting in fewer overheated tires. But the incidence of bead failure is relatively small when you take it all into consideration.

Aggressive camber, excessive brake use and poor driving decisions lead to the majority of right front tire failures.

You apparently havent seen his pictures, if so you must have a helluva big foot or you just bully type.
 
Too bad Reutimann didn't do a better job in the 10 last year, eh?
The field is being set by 2012 owner points and so Miss Thang starts 37th.

Good news is that Brad and Clint will start on the Front Row!

Some Chassis Selections and Notes by Teams for this race

  • Chassis selections for Las Vegas: see the list of many teams and what chassis were selected by the team to run at Las Vegas Motor Speedway:
    MISSING? why are some teams missing? some teams do not report what chassis in the race previews, press releases or websites.
    #1-Jamie McMurray: chassis not reported on race preview.
    #2-Brad Keselowski: Primary Chassis: PRS-838 New chassis; Backup Chassis: PRS-837 New chassis
    #5-Kasey Kahne: Francis will unload Hendrick Motorsports Chassis No. 5-779 for Sunday's event at Las Vegas. Kahne will drive this car for the first time during Thursday's test session at Las Vegas.
    #7-Dave Blaney chassis not reported on race preview.
    #9-Marcos Ambrose: The #9 team has prepared chassis No. 840 for Vegas. This is a new chassis that the team built in the off-season.
    #10-Danica Patrick Chassis No. 10-751: Chassis No. 10-751 was first used by Patrick in October 2012 at Kansas Speedway in Kansas City when Patrick started 40th and finished 32nd after an accident ended her day after just 154 of 267 laps. Patrick then tested the car in January at Charlotte (N.C.) Motor Speedway.
    #11-Denny Hamlin: chassis not reported on race preview.
    #14-Tony Stewart: Chassis No. 14-707: This car made its first start in May 2012 in the non-points NASCAR Sprint All-Star Race at Charlotte (N.C.) Motor Speedway. It was an unassuming debut, as Chassis No. 14-707 started ninth and finished a quiet 17th. The car sat idle until returning to action for the Labor Day weekend event at Atlanta Motor Speedway. It won the pole and led eight laps early in the 327-lap race, but as day turned to night, the handling of the car deteriorated, leaving Tony Stewart one lap down in 22nd when the race ended. It has since been totally rebuilt with 2013 Chevrolet SS sheetmetal, and it will be used for the open test Thursday at Las Vegas Motor Speedway before serving as the No. 14 team's backup racecar for the remainder of the weekend.
    #15-Clint Bowyer: Primary chassis No. 738 finished second in the 2012 season finale at Homestead-Miami, and finished sixth at Kansas in the fall. The backup chassis (No. 724) raced to top-five finishes at Bristol (fourth) in March and Dover (fifth) in June. It also finished seventh at Bristol in August and tested at Charlotte in January 2013.
    #16-Greg Biffle: Primary Chassis: RK-825 Last ran Kansas  finished 27th; Backup Chassis: RK-809 Last ran Texas  finished 10th

    #29-Kevin Harvick: will pilot chassis No. 396 from the Richard Childress Racing NASCAR Sprint Cup Series stable in the Kobalt Tools 400. Harvick last drove this RCR racecar to a 12th-place finish at Chicagoland Speedway in 2012.
    #31-Jeff Burton will race chassis No. 393 this weekend at Las Vegas Motor Speedway. This No. 31 Chevrolet was utilized five times during the 2012 NASCAR Sprint Cup Series season at Auto Club Speedway, Darlington Raceway, Michigan International Speedway, Atlanta Motor Speedway and Kansas Speedway.

Seems like there's been a lot of posts on NASCAR's Air Titan system. I saw this a little while ago.


Air Titan still on sidelines

The Air Titan, NASCAR's new track-drying machine, is not in Las Vegas.
After Daytona, NASCAR officials took the Air Titan back to the Research and Development Center in Concord, N.C. to conduct more tests on the equipment to see what improvements can be made.

So they're trying to make improvements to it. Doesn't sound like a bad thing. As far as them transporting this from track to track..... If you've ever been to a NASCAR race you'd realize that each weekend an extraordinary amount of equipment is brought to the track by NASCAR, the media, vendors, etc. It is a traveling circus. The amount of equipment that they used @ Daytona, if that's a true representation of the final setup, would easily be transported to each venue.

That's good to hear. They may have been able to get at least some Nationwide practice in yesterday with the Air Titan. It sounded like the rain was sort of on/off most of the day.

Friction between the brake pads and rotor provides braking and that friction generates heat. The rotor dissipates that heat. How would a smaller rotor generate less heat?
