Any ideas??
 
Ok so I have posted on here several times this season and now our racing season is over, I am posting a couple links to pics of my car launching, just wanting to know how I can get the wheels up a little more to guarantee maximum weight transfer all the time mainly in the scorching heat, the car is good but not great and thats where I wanna be here are the suspension specs...
Slide a links
rancho Rears
Afco multi Leafs
Koni Spa1's in front
214 rate moroso springs
4.56 Gear
5600 Converter
Trans brake
30x9 Tire
400 Turbo
Car 60's 1.48-1.49
ETS 1/8th mile 7.10's

Any and all suggestions are appreciated.
Here are the links.

Ditch the Koni's and put on a pair of Calvert front shocks. Best $100 you'll ever spend.

Can the engine deal with more top end RPMs? If so, you should put more gear in it.

JMHO. Good luck.

Engine is pretty well topped out as it is, thanks for the response.

Use the Cal-Trac suspension system. It just flat works.

Your car looks fine off the line. You should rethink the idea of getting more air. Once you front wheels are of the ground you have 100% of the weight transfered to the rear tires. What you should be looking for is the least amount of power to move the car forward the quickest. Look at the shocks for control. The Konis are fine. If you need to go futher you may want to look into converting them to double adjustables. The goal of the front shocks is to control the rise and fall of the front end. The most efficient launch is when the front end rises slowly and settles down slowly while the car is still accelerating. The rate that the shocks extend and collapse is dependent on many factors: Tire size, rear gear ratio, first gear ratio, T-brake, torque converter stall, vehicle weight, horsepower, track conditions, etc.

If you were to graph the front bumper during a launch you want a nice even rise and a nice even fall throughout the first 20-60 feet. You don't want the bumper to pop up quickly then fall slowly. you also don't want the bumper to pop up quickly then fall quickly.

Optimum weight transfer occurs when the front shocks are at Maximum extension.

Read up on Center of Gravity, Instant Center and Percentage of Rise. Find someone who can help graph this for you and you'll be on your way to a hard launching car without the unwanted air time.
