Dom, I won't be able to help you on this one

But here is the low done

1.  Measure the wheelbase.  Best way it to go from outside rim edge to outside rim edge.  Just make sure if you measure from the leading edge on the front you measure to the leading edge on the back.
2.  Vehicle drives up
3.  Measure from the center of the front wheel down to the start of the ramp.
4.  Take the distance travel up the ramp and divide it by the wheelbase
5.  Multiple by 1000.
6.  Have a BEvERage.

Ex.  If my YJ (WB = 93.4") drove up the ramp a distance of 73", then my score would be 73/93.4*1000 = 782

Here are a couple of links

If you need more info, I can meet up with you sometime this week

JUST MAKE SURE TO BRING A CALCULATOR!!!

I don't know how to do them either, but with Scott's directions, and the use of a calculatrice, we should do ok.

I'll give you a hand, let me know the details, when, where, etc.

BEWARE of cheaters :D

Cheating on a ramp is when you only air down 2 tires and not 4.

Cheating on a ramp is also when you air down below the psi you normally run on the trails.

Cheating is when you disconnect your shock.

OK, how about swaybars and trackbars?
What about not airing down at all? (Or which two tires?)

Basically, you set your rig up as you NORMALLY would for a trail ride. If you only go down to 15psi, than that is how you should ramp it.
If you disconnect swaybars, than go do it for ramping.
If you have no trackbar, than no need to get one :)
If you want to see the difference airing down makes, give it an "unofficial" try at lower psi, about 10psi would probablly score about 2-300 higher than 15psi. And when you see the difference, you may even try a trail at that psi to see how much more performance you may gain :wink: And next year you can ramp it "officially" at 10psi :lol:

The biggest advantage you can get is letting air out of the front driver and rear passanger, this will produce the highest score.
The measurement is taken at the point that the rear driver tire starts to get "air". Have the competitor back down a "tad" to get the proper measurement with all tires making contact with ramp or ground.

We have always used the centre of the rim to the centre of the rear rim to get our wheelbase. It just has to be "close" when you measure.

Of course if this ramping is entirely for fun with no prizes and no bragging rights, than do whatever you want:D
