Lambo crash at Texas mile.

Oh my.  Don't blame the driver if he takes up a more sedate hobby, like croquet or golf.

He probably will as soon as the ringing stops.


I'll stick with the bikes thank you.  It scares the daylights out of me the thought of being tied to something like that.  I prefer the exit stage left idea.

Maybe he sould have stopped like he did in the spring with no chute

Is this the same Lambo that in the spring, got away from the driver off the line, and then he was spinning it at the top end to get it stopped?

[Stan Back]

It doesn't look like a roadster . . .

I tryed the drag chute in  05 when we went to Texas. You are correct, too big and too short lines, it unloaded the rear end of the car and fishtailed, sure got my attention. My car weighed about 4700 lbs. at the time with only rear drum brakes, so I thought I needed more chute, WRONG WRONG.

  Gary how high is the mounting for the drag lines?
  We never have those problems and as stated before, both at once by accident at 275 mph.

You are not going to stop faster by spinning the car!! I think he just did that for fun.

Maybe he should have stopped like he did in the spring with no chute

It sure looks like the same car from the spring races. Look at the spring video and you can see the chute mounting was not solid and was flopping around, you will also see that the chute anchor line is mounted very low, what appears to be maybe 6" off the ground.   

In the crash video was that an earth berm or piled up debris the car hit off to the right just before the car went airborn?

At least the driver is Ok and that may well be that he had more luck on his side this time.

John, my chute mount is pretty low, but I have never had a problem with the bonneville chute going 248.

This is the same car that spun in April in shutdown and also spun 200 yards from the starting line.
It made around 1800hp to the wheels(underground racing twin turbo kit)

He ran 250.1 the meet before and used no chute.

Dear Folks:

I tend to try to keep a low profile and certainly don't want to get into a large debate, but for the sake of safety, I would like to share the information I learned from Jim Deist in 1993.  At that time we were running two Simpson Crossform drag chutes on the Bocar.  I asked Jim for advice on mounting.  His advice was figure out how high the chutes fly (he gave me a value for our chutes) and draw a line starting at the center of mass vertically and horizontally of the car  to where the chute would fly at deployment length (in most cases this works out to a line drawn from approximately the front of the cam out to the center line of the flying chute).  The mounting point for the chute should be along this line.  Above the line it will try to pull the front of the car up and below the line it will try to lift the rear of the car - neither of which is something you want to have happen.  With the Bocar, this placed the attachment point on the roll cage immediately above the body. 

We used these same chutes on the Berkley for a number of years at Bonneville, including the time that I grenaded the motor at 280, had a bit of the fireball situation, and popped both chutes.  In 2008, I popped one of these chutes at a little over 301 and then 310.  However, I must say that the drag chute was pretty violent in stopping at over 300.  Since then, I bought a pair of Strouds as a high speed chute and a low speed chute.  Both of these have very long deployment lengths.  Using the same rule, the mounting point ends up low on the top of the push bar.  I still run one of the drag chutes in case something goes wrong and I really need to get nylon in the air as quickly as possible and need a rapid stop. 

I hope this contributes to the debate on parachute mounting.

Best regards,

Bonner
P.S.  We think we have our oil pressure problems licked.

Kinda tough to draw this line with DOHC engines.

Bonner, that's good advice. DW, be nice.

[manta22]

Bonner;

That is exactly the same answer Jim Deist gave me 5 years ago. It is certainly good advice.

Suspension also looked pretty soft. Watch the nose bob up and down rather radically on shifts. Transitions from drive to coast can be very upsetting.
