chase, first the rear window question now this? why not look around for a while before you post this awkward stuff. have you done any mods yet to your car or are you still just looking around? why not just s/c the car and see if you are happy then go from there....seems like you have no lack of funds even though you are like 15 or 16.

[QUOTE=mikegarrison,Jan 31 2006, 03:08 PM] Dude, you and I have been through this before. I suggest you go back and look at the last time we went through this topic. I ended up acknowleging that gearing is important for drag racing times, because of what happens in first gear. And I thought you ended up realizing that gearing is not important other than that, because horsepower limits the acceleration once the engine gets into and stays in its power band. Any time the cars are in the same gear, the one with the shorter gears is accelerating harder. But this is exactly balanced by the amount of time the

Chase, please take careful note of Wisconsin's post here.
Most threads in this forum is about people who want to increase (numerically) their final drive gear ratio so they can accelerate more quickly. This is IN SPITE of having to potentially shift more to get the job done. The accelerative advantage of "gears" can outweigh the disadvantage of having to shift one extra time (or even two extra times).
You want to go the opposite direction and thus, the converse is true .....................
the reduced accelerative capabilities of lowering (numerically) the FD ratio will outweigh not having to shift that extra time. In other words, you will save a bit because you will not have to do that extra shift, BUT, you will lose a lot more because your car has slowed down considerably.
The choice, of course, is still up to you. (Not that you will easily find a FD gearset that will do what you want.) Insofar as spending all that time and money to increase your engine's redline, so you can achieve 60 in second gear, well, again, that's your money and it's the longevity of your engine that's at stake.
My suggestion to you? ......................................
Since you are having to do that extra shift anyway to get to 60, throw in some 4.44 or 4.56 gears. These will more than make up for having to do that extra shift. However, your real world top speed will decrease and your highway cruising rpm will increase, but your goal of getting to 60 real quick will be had.

No, the car does actually physically accelerate faster. Yes the shift points change, but this is more of an indirect result.
Your horsepower and torque are still the same. You still have 9000 (or in your car about 8000) rpm to work with. What happens is gearing changes the way that power is used. Just like a shoter (bigger) gear on a bicycle will allow you to pedal easier, thus faster, the same is on a car.
here is a technical article explaining a bit more. this is from hot rod magazine:
[QUOTE]A few simple math formulas can help you select the right gear ratio and tire diameter to optimize your vehicle's performance. Because performance cars are often used for both street and track use, gearing a car to do both usually demands a compromise.
