Lambo crash at Texas mile.

[jl222]

  That's how the 222 car chutes are mounted, 16'' at cam 19'' at mounting [approximate as engine is out but pretty close]. no problems when pulling big chute at high speed.
 I guess one thing that can be learned from this is, if you can't get the correct mounting point get a smaller chute and longer lines.

I didn't get to talk to John this year, however my test engineer's point of view is this:

If someone is reporting that they can pull a chute at speed and not upset the car, I would copy their attachment.  I spend my time working on problems that other people haven't figured out.  When a professional has, copy it.  The still pictures of the Lambo show it all, WAAAAAYYYYY too low of a mounting point on a short car and a short riser to the chute.  What I can't figure out is why these guys (there were two, and where there's two, there's twenty) are willing to flat spot tires at $2000+ per set and not use a chute.  Is it THAT hard to re-pack?  I've been packing chutes my entire life and it sure seems a lot cheaper than trashing tires that I would need on my next run.  Dragging the chute causes damage after 10 to 20 runs?  Duct tape the high spots before they scrape, and new chutes are cheaper than replacing flat-spotted race tires.  Quicker to replace too.

To translate Jim Diest's advice to OHC or DOHC, the height of the back of an UHC is about the top of the bell housing.  Depending on the car (some classic's have a lot of mass in the frame), I'd go with some point between the top of the bell housing and the top of the tranny case and draw a line to the chute's deployed length with the chute flying at a height observed from other cars.  I could be wrong, I'd bet that position comes pretty close to JL222 and Bvllrcr's setups.

It looks like they went under the car to the transaxle, riser probably even lifted up on the rear of the car not from the attachment point.

 The frame in the 222 car is an Alston pro-stock complete body off chassis, their the ones that engineered the chute attachment point and design of attachment.
  Looking and stopping the motion of the opening of the chute one can see that he was on the brakes before the chute opened, I can never get the video to stop in a place to see if the tires acually came off the ground, anyhow I wonder that if he was on the brakes and then when the chute hit it caused him to brake harder

Someone mentioned before - too much money, not enough talent and the wrong consultant.

They should be running the  Bull Run, more tv time there.

I was there.

The 'chute attachment point could NOT have been lower.

I talked to a guy that watched the car go through the traps, the 'chute deploy, and the fun afterwards.  He told me he "thought" the rear wheels lifted off the pavement. (a lot happens at 238mph).

From watching the films, it appears it went sideways into the dirt and then started the fancy dismount.

The safety vehicles were moving before the car stopped.
