[QUOTE="Willie, post: 16664254, member: 14133"] Form Follows Function.... or is it Function Follows Form? The age old argument. The answer is, "It depends." Gear choice depends on your goal, or how it "feels". One dictates the other. It's just which is most important to you. I'll post just one scenario, optimizing 1/4-mile passes. First come up with a top speed for your goal. Then you have your engine redline and tire size as constants. Given these constants, trap speed at redline at the top of transmission 1:1 gear (typically fourth), calculate ratio. That's it. The way the car "feels" is what it is. Goal determines feel, or form follows function. If you don't drag race often and the feel is more important, throw the calcs above out the window. It doesn't matter. Feel determines goal, or function follows form. I used to drag race frequently. Putting my numbers in, my ratio is 3.31. Although my car has 3.73's, I'm somewhat content nowadays because I do not race much at all any more. And they have been super quiet since day one. So to each his own. [/QUOTE]
