Tape a vertical line on the car at the intersection point. Where the vertical line intersects the horizontal line (the camshaft line) is the approximate instant center of gravity.
Just so, How do you set up suspension in drag racing?
If the car gradually wheel stands or bounces violently, adjust front suspension first, then rear. If there is rear tire shake, wheel hop or excessive body separation, adjust rear suspension first, then front. After the car has been adjusted to launch straight, test launch and include the first gear change.
How do you adjust the ladder bars on a drag car?
Similarly, Where should my instant center be?
Instant Centers are easy to visualize. You find the little spot the same way on both sides of the front of the car. For this review we will take a snap shot of the RF suspension. Your A-Arm is bolted to the frame via an ear that is welded to the frame horn.
How do you set an instant center on a drag car?
How do you adjust the ladder bar suspension in drag racing?
How do you adjust drag suspension?
How do you adjust drag shocks?
Using the recommended settings below, start testing your ride and handling. Turn the knob clockwise to make the shock stiffer or turn it back counterclockwise to make it softer. Starting at “0” and incrementally stiffening the shock minimizes guesswork so you can truly dial in your ideal performance.
How does ladder suspension work?
By using the Ladder Bar to carry power to the chassis, the front end reacts by rising. As the front of the car travels upward, rapid weight transfer is created which “plants” the rear tires and propels the car forward.
How do traction bars work?
Traction bars are designed to prevent axle wrap and wheel hop. Axle wrap happens when the torque at the rear wheels causes the axle to go the opposite direction of the tires. … Traction bars make sure all the torque is applied to the wheels and helps keep you going straight down the road without slipping.
How do you adjust the pinion angle on a ladder bar?
Using the bottom adjuster on the driver side ladder bar, adjust the pinion angle 1-3 degrees below the driveshaft angle. 3. Using the adjuster on the passenger side adjust the ladder bar back up until the bolt goes back into the hole and through the crossmember freely.
Why is instant center important?
The instant center length can actually affect the overall (race car + driver) reaction time. Bickel states that if your reaction times are good, a long IC point (50-60 inches is generally more desirable than a short one (50 inches or less). This will plant the tires smoothly and keep them planted a long time.
How does roll center affect handling?
Chassis rolling at one end of the car or the other gives more grip to that end of the car. … This is because roll center has an immediate effect on a car’s handling, whereas anti roll bars, shocks and springs require the car to roll before they produce an effect.
What is a 4-link rear end?
A four-link suspension uses links to locate the axle from moving side to side and front to back, while allowing it to travel up and down and articulate.
What is anti squat?
Anti Squat is a term for suspension engineers to determine how much the suspension mechanism itself is resisting suspension compression. Anti-squat is suspension’s mechanical resistance to compression due to forces from the engine (when on a bicycle human is the engine).
How do you adjust coilovers in drag racing?
What is anti squat drag racing?
Anti Squat (AS):
This is a term used to describe how much the rear of the car will Rise or Squat during launch. … By comparison if a chassis has 100% AS then the rear of the car will not rise or squat and if a chassis has less than 100% the rear of the car will squat.
How do you get traction in drag racing?
Spin the tires just long enough for them to generate steady, even plumes of smoke, and then move on. This technique helps get the most life and traction from your expensive drag slicks. Remember to rotate your slicks weekly. Not everyone drag races on slicks.
What is bump in drag racing?
The “Bump Box” has totally transformed the way many drag racers stage their cars. By controlling the trans brake with a high speed micro processor, the car can be bumped into the second bulb with extreme precision and control! Allowing the driver to focus on the tree, and not worry about rolling the beams.
Why do drag cars lift up?
It’s because the shape of the car uses Bernoulli’s principle: the difference of pressure between the air above and below the car causes a net upwards vertical force which increases when the car goes faster.
How do you adjust shocks?
7 Steps To Finding Your Perfect Shock Setting
- Set bump and rebound full soft.
- Do an out and in lap.
- Add bump in two click increments until the “feel” of steering improves, doing an out and in lap with each adjustment.
- Now add rebound in two sweep (or click) increments until car “feel” (driver confidence) improves.
