would be cool to see some in tunnel footage of testing and how it all takes place!!

I think I'll just wait my 5 years or so before it's standard practice and then check it out..

We'll be updating this story in a few days ...

A year ago it was mostly just rumour and innuendo, and we don't post anything until it is confirmed as fact.

Racecar Engineering only published their detailed article about the tunnel in the current issue of StockCar Engineering Magazine, and that article is only available in the print version of the magazine, and not on their website yet - as soon as the new article is available on their website, we'll provide a link to it.

The new article goes into huge detail about how the inside of the tunnel is set up, how tests are carried out in the tunnel, and the exact advantages of using a full sized tunnel over a wind tunnel.

The new article also says that a steam catapult like what they use to launch fighter jets off carriers has also been considered to increase the maximum speed possible inside the tunnel.

It also includes full details on the equipment used during testing, which includes datalogging by Pi Research, a pair of AQS Air Quest 1000 dehumidifiers, and a Vantage Pro weather controller - so essentially they can set the environment in the tunnel however they want it, for testing cars at different humidities, air temps etc.

The tunnel even has a turntable in it at the end of the tunnel so the cars can be turned around quickly for the next run, and Racecar Engineering's new article also reads ...

The test car can also tow a second car through the test section to simulate drafting, and multi-car tests have been conducted with two cars running nose to tail or side by side

As soon as the new article is available online, we'll provide an update and links to the new article - it has some very interesting diagrams and illustrations, and completely new info about the inside of the tunnel and how it is used.

My god that is awesome!

It's wild huh ! I'll update the post with the illustrations from Racecar Engineering's new article as soon as they post it on the RE website, but in the meantime, check out the diagrams in the patent filed by Ganassi Racing for an idea of what the inside of the tunnel looks like ...

Hi All,

A number of blogs and forums are abuzz at the moment with "news" about a disused road tunnel allegedly being used for testing racecars.

If you look at post one in this thread, you'll see this thread was started back in November 2008, two years and four months ago LOL :)

What is new is that on 9 March 2011, Racecar Engineer Magazine published an update article titled "The secrets of Laurel Hill revealed" which has new info on the tunnel.

We have published an updated article with new info about the tunnel here ...
