When you activate the chute handle, there is a delay while the drogue is feeding out, then pulling the main chute out, and all of the leads, then it has to inflate... You can figure on a one second delay at least... During this time, don't lift, or do anything other than stay hard on the loud pedal to keep the weight transferred to the rear... when the chute hits, everything shifts forward... when your head comes back up from that, then lift...
Lifting too soon, causes weight to go neutral... braking before the chute hits makes this worse with forward weight shift... and then the chute hits and it can actually lift the rear of the car off the ground... There was a Lambo that had this happen at the Texas Mile with a very slight cross wind, car went end over end numerous times as a result...
I absolutely need the chute at the Beeville Tx Mile event due to the short shutdown area... lighter car or those with better brakes handle it fine, but I've had too many serious pucker moments... 5280 feet to speed up, and less than 3,000 to slow down... I've used every inch of available track on occasion... I've had guys in Vettes, tell me it's no issue... one, these particular guys are just getting over 200, two they have specialized brakes and six piston calipers... I've stood hard on the brakes for the entire shut down and still made the turn at over 70 mph...
In the video, you'll see the crash... They go to a slow motion part, and notice the brake lights are on before the chute inflates...
