OK, so all the bad reasons to do it. Having jumped various cars and trucks (most of which were completely stock) well over 100 times I have learned a few things. As bad as it probably is to tell you how to do it, here are a few things I learned. By no means is this all you need to know, it isn't. It is dangourous to you and your equipment and anyone around you. Start small, I know shopping centers with properly shapped sidewalks that if hit with a touch of speed can toss an axle in the air. I have also heard of horror stories where a minor little rise that looked like it could barely toss an axle in the air nearly endo a car as the rear hit just as the front came down. Bad thing can and do happen
Jump a rise, never off a cliff. There was a wash that I crossed going to work where the flat road would drop into a wash then rise back up then suddenly go back to level. If you approached that too fast you would go from level into the wash, or drive off a cliff. Those were violent and not enjoyable. But the rising crest worked fine. Took a while for all the physics to kick in but this is a summery of it. You WILL average 1G vertical load. When you are jumping your are at 0G and have to make that time up with 1+G. You can preload your G bank account with a little 1+G on the rise that way the sudden payment at the end isn't so bad. If you go off a cliff that payment adds up real quick and the payment at the end is very hard.
Throttle. You need to be fairly nuetral about this. If you lift as you approach it you will nose into it. Not good. But you can't be burried in the gas either or bad things happen when spinning drivetrain gets real good traction as it smashes into the ground. You really don't need nor want much speed. 35MPH is about as fast as I will pull this off. A few that I knew really well I would push to about 50, but those are very well tested and I had done them countless times. Also wasn't my car. Anything faster then that and you have not found the right grade to drive over.
If you have adjustable shocks, run them stiff.
For the actual photo, this will involve a second fool. My camera of choice for this is a GoPro Hero2. There is a 10 frames in 1 second mode that will let you get 10 high quality photos of the carnage as it unfolds.
If you live to tell about it, (that is a bit of a disclaimer in there) be sure to post what you get. Remember to start small.
There is the foolish advise for the day...
