Bringing it back after a week because I'm still catching up after being gone...
I used to do it every time I went to work driving my 1984 Chevy Celebrity Wagon- with the 2.8L V6 engine and 3 speed auto. It had loads of torque in a surprisingly light chassis (just a hair under 3100 pounds), and the Dynomax Super Turbo muffler in place of the 60 pound factory piece helped a tad too.
If any of you are in Houston- think about the Greenbriar just south of Highway 59- around 1993-1994. I always came off the freeway in the mornings (northbound) and made the right turn to head south on Greenbriar, planted my foot on the floor, and about 50 yards after the turn the road had a HUGE rise where the railroad tracks were just paved over, then launched off it at only 45mph all the time. That was just enough to get the car in the air, but not quite enough to make it bottom out when I hit the ground. That fraction of a second in the air every morning was smooooooooth. I loved that car- you could fit an entire twin size bed in the back.
The truck (95 Nissan Hardbody) I've jumped a few times, but not intentionally. There's one street in Austin close to UT campus (32nd street) that has a few road big road humps heading east towards I-35... and they're hard to see at night. One of the humps in particular is at the bottom of a long grade, so you can be going quite fast when you get to it- and it's easy to forget about because you normally don't give a damn about road humps if you're only doing 30mph. Well... 50+ and you get airborne. Big time. It's definitely not too fun when you're not expecting the jolt!
Oh- nobody was injured, and I always kept my car/truck in control- and no dead stop signs, tickets, deployed airbags, or alcohol was ever involved either. Good times.
