Can you guys share the info that you gave him? Tire pressures for dirt? RR with bead lock tire pressure? Cross? Can some one explain calculating bite?
Sent you a PM.
Calculating side bite:
The formula for lateral acceleration is
LA=V2/32RThe formula for finding the amount of weight transfer is
Transfer=W x CGH x G
TWWhat the hell does that mean!
It has to with Lateral Acceleration and Weight Transfer.
Lateral acceleration is the sideways force which a car generates in a turn. It is a measurement of the maximum amount of cornering force a car will generate.
Lateral acceleration is dependant on two things: velocity (speed) and the radius of the turn.
Lateral Acceleration is the Velocity squared (expressed in feet per second) Divided by the Radius Of The Turn x (times) 32.
Example:
A race car is tested and found to corner at .85 G's. One G equals the weight of the car, so this means that the car's suspension system can corner hard enough to withstand a sideways force equaling 85% of the car's total weight and still maitain tire contact with the track. The more G's of lateral acceleration the car can produce under maximum cornering, the greater cornering power of the car.
A reasonable lateral acceleration for a Legends (or Dwarf) Car would be .85-G to 1.0-G for a paved track car, and .75-G to .85-G for a dirt car.
Once the later acceleration for a particular car set up is known, the actual pounds of weight a car is transferring from the inside wheels to the outside wheels during maximum cornering can be calculated.
There are three major factors which affect weight transfer: The car's weight, center of gravity height and it's track width. (See formula for finding weight transfer.)
In other words, the amount of weight transfer in pounds eqauls the car weight (expressed in pounds) times the center of gravity height (expressed in inches) times the lateral force coefficient (expressed in G's) all divided by the car's track width (expressed in inches).
References used for the above information come from the "Automotive Math Handbook" by Forbes Aird and "Dwarf Car Technology" by Steve Smith.
Check them out... Both are excellent books. Obviously, there is more information in the books. The "Dwarf Car Technology" book is easier to understand, and gives some practical use information.
You asked for the formula to calculate side bite.... So there you go.
Have Fun!
