New track drying system ready for Daytona (if necessary)

Bout time they did something proactive to combat the rain.

And with this, Bruton won't have to refund tickets for Bristol, that's for damn sure. Unless it's a epic downpour that won't let up.
 
I wonder if those 30/15 minutes projections are real. Even if the racing area is possible to do, pit road has to be dried as well. That probably wouldn't happen until the red flagged cars returned to the track.
 
I'm just happy they are trying. Rain delays were half the problem, drying time was the other half that burned up the time between showers. (Yeah, I said burned)
 
Whatever they reduce it by is great news. They are talking numbers of up to 80 per cent quicker by the time they feel that they get this perfected. That's amazing. We've been real lucky in NASCAR that rain delays haven't been all that commonplace. Yeah, we've all sat through them but they've been relatively rare for an outdoor sport. I hope I only ever have to hear about this new track-drying system rather than see it in action but if/when we do see it I'm sure the thousands of paying customers at the track will be thrilled.

Side note. I wonder how much this will cut into NASCAR's concession stand profits?

Don't be concerned, as nascar always takes care of profits. I'm betting they make a ton on goggles and hurricane umbrellas by blowing the water toward the fans.
 
How many chunks of asphalt track do you think this high pressure blowing, or sucking if you prefer, will be dislodged?
The good news, in 20 minutes the track is dry!
The bad news, we have to truck in asphalt and do pothole repair!

Seeya tomorrow race fans!o_O

It seems that they'd have thought of such things during what must have been hundreds of hours of testing.

That was my first comment when this was announced a week or 2 ago. Everyone laughed, so brace yourself.
 
I don't think we will see potholes. The system is a vacuum that is assisted by some sort of wiper, and air pressure. Not air speed. Big difference. If they do it right a section of pavement will be pressurized and then vac/wiped clean.

This is how I imagine it will be. Not that I worked on the project. And I'm not an engineer. But I did sleep at a holiday inn express last night.

Not a big deal. Most of the engineers on here primarily focused on aerodynamics anyhow.

OK, I thought they said they would blow it off with compressed air, which could force water down into the pavement. Then the cars get out there and heat it up and layers come loose.

I slept at a holiday inn express too.

USE compressed air is how I saw it. And vacuum it. sounds like a pressure cooker of sort.
 
Some more on this.

Elgin Sweeper Introduces Crosswind Specialty Track Sweeper: Elgin Sweeper has introduced a modified Crosswind Specialty Track Sweeper that is set to make its debut at NASCAR racetracks around the country this racing season, beginning with the Daytona 500 on Feb. 24. The Track Sweeper plays a supporting role in a new racetrack drying initiative that features a combination of air power and vacuum suction to dry rain-soaked racetracks. The regenerative air Track Sweeper adapts features from Elgin Sweeper's highly successful Crosswind GRS (glycol recovery sweeper), a special-purpose sweeper used to vacuum liquid glycol from airport runways. This specialty sweeper includes unique features developed for racetrack sweeping and maintenance applications, such as a side air-blast nozzle, a reverse sweep system, a 20,000 CFM-rated blower and a hydraulically-driven side broom with plastic bristles.

During track testing conducted in conjunction with NASCAR last November in Daytona, this same vacuum technology proved to efficiently vacuum water from the pores of the racetrack, and worked even better with the new track-drying technology designed by the NASCAR Research and Development Center. Working together to remove moisture from the track surface, both technologies dramatically accelerated the drying time. Developed as a more effective alternative to the current track-drying method, the system, featuring the Crosswind Track Sweeper, is expected to expedite the process.

How funny would it be if the giant blower hits pit road for the very first time and we see officials getting blown right over the wall?

Just to give you an idea. A commercial backpack blower is 750cfm at 200mph. I wonder what the velocity of the 20,000 CFM crosswind thingy is?

Andy's crosswind hit about 340 after 14 Martinsville hotdogs. Maybe you can ask him about this stuff.
 
Those are industrial compressors I thinks. One per little collector. Neat.
