On a stock car, here's following top speeds on 5th gear based on your FD.
4.6 FD: 118
4.3 FD: 126
4.1 FD: 132
3.9 FD: 139
3.7 FD: 146
Technically, your 5th gear should be the least of your worry. How often are you in the 100-146 mph range that your 5th gear will mean that much to you? Usually people complain more about the lower gears, as with more power, you are going through the gears quicker, making 1st and 2nd gears more "useless" as you say. So lowering your FD to something like 3.7 will give you more time in each gear and help reduce tire spin as well. |
I haven't seen this website before. Thanks!
