As I've read there have been comments relating to the chute deployment. It would appear brakes were applied before the full deployment of the chute and it should be vice versa.
Undue rear end lift transpired and the crosswind pulled the chute to the cars' left. This caused the Lambo to veer to the right with loss of rear traction and head towards the turf/grass then the nose caught a small burm proceeding to the violent end over end crash.
Other comments of observation have been the chute size was to big and the chute tether to short. Both of which could create a to abrupt destabilizing and ret@rd!ng of the cars velocity.
All speculation of course.
$h!t can happen at those speeds.

This is a testimony to Underground Racing great preparation of the Lambo SL with all proper safety equipment
Also a very fortunate driver.

Hey Juan,

I just don't think there have been that many Gallardos running that fast so the experiments on parachutes have been limited. You are right, the driver is VERY lucky to walk away from that wreck.

Looks like the opposite? Brake lights came on after the parachute?

Watch closely on 1:12 and 1:13 min segment of the video. Brakes are on and chute is coming out. Both forces hitting nearly simultaneously.

Please read my exact correct comment. I said "brakes after FULL deployment of the chute.

Mind you these are not my opionions/comments but rather from long time drag racing experts. One drives through the complete chute deployment then brake. This attempt is to maintain the rear stablized, ie. minimize rear lift and loss of contact patch of the tires.
One impact at a time on the cars' vector forces. The car needs to be as stable and flat as possible for the opening impact of the chute. With strong braking the weight transfer is forward making the rear light/lift and then the chute FULLY deploys, well NOT good! The car's already has a light rear then the chute impact = compounding rear destablization. Thoughts are the chute was too large and the tether too short. This made rear lift worse. Two forces took effect simultaneously, chute and brakes. It was also commented that the ceramic brakes of the SL bite too hard further adding theoretically to more abrupt forward weight transfer and rear lift. Also the short wheelbase of the car may also add to complexity of all that came together in a wrong way.
Add to this the strong 30 mph crosswind which pulled the chute to cars' left causing front to go right. The rest was a horrible incident and a very fortunate driver. The car has a price but life does not.

But hey what do I know. I'm just conveying info from individuals that know much more than a moron like me.

Cheers and no more from.

Ranger,

I've also read on other forums about the brakes versus chute deployment being done incorrectly here, helping lead to the accident. Thanks for your great explanation. I've never done, and probably never will do any high speed runs like this. Knowing about how the chute should be deployed is interesting though.

Thanks for the information.

I made a thread about this in the Off Topic Forum...

Underground Racing Supperleggera Accident at Texas Mile...Looks like SW's car

While S.W. was not the driver, I'm pretty sure it was his car. There are only a handful of UR TT Gallardos, and even fewer Supperleggeras. Given that this was an Orange Supperleggera and that S.W. is often at the Texas Mile, I'm willing to bet this was his car.

Fortunately, Richard is ok and that was not my car. My car is safe in my garage. I only use the Supra for mile events.. I'm going back one more time to go for 250mph..

Sad to see that happen, heard the driver walked away fine though!

JonnybravoM3 · 30th December 2010, 22:19

Glad the driver made it out safe!!

So... is that a write-off or will it buff right out with some turtle wax?
