you're about to see a very high-speed run put down by danny compton. e car he's driving the challenger 2 originally raced by danny's dad nicky thompson. >> oh. >> the name very popular in the racing world. the car built way back in 1968. it's been danny's dream to rebuild it, restoring it for the past four years. here's a test rupp. he gets it up to 390 miles per hour safely. but it's on the deceleration. watch this. that's not a champagne celebration. that's actually the fire extinguishing system that went off under the heavy deceleration when the chutes popped in the back. >> this had nothing to do with heat or fire or anything. >> danny was completely blinded at first. he did have to raise the canopy so he could see and turn the thing around. they fixed the issue and the next day he ran 419 miles per hour. >> that's so awesome because it's in his dad's vehicle. >> it is awesome. that makes danny only the 13th person ever to go over 400 miles per hour in a piston powered car. danny and nicky the first father/son duo ever. >> that's great. >> awesome.
