Default How big a difference is 1 second in a 1/4 mile race?

Whenever me and my dad race at the 1/4 mile track, he of course beats me even though we have the same car. (acura rsx type s)

I'm wondering why when I get a 15.6 1/4 mile time and he gets a 14.9 or 15 second 1/4 mile time, it seems as if he's so far ahead.

Isn't 0.5 seconds a small difference when it comes to car lenghts?

Also what techniques can i use to finally beat him?

No. When traveling at high rates of speed, distance becomes exponentially shorter. The common formula for this is distance = rate X time. You see, when you divide the distance you travel by the rate at which you are moving, your time gets cut by the length you have moved. This means that 1 second is like a totally long time. And in a 1/4 mile race? Forget about it.

In terms of racing, that is a huge difference. In terms of car lengths it would look rather close, to a casual observer.

The easiest way to beat your fathers time would be to lighten the car. Certainly the trunk filled with stereo equipment will not be to your advantage in a race. Also, shifting is everything. It's not going to be easy to outshift an experienced driver, but you can certainly practice this. Cars accelerate better at higher RPMs, you certainly don't want to redline it, but you can high rev it before shifting.

If you're running an automatic, you can still shift. Start off in a low gear and then push forward into a higher gear as the Rs get up there. This won't pose any danger of messing up your car. The shift er in an automatic doesn't actually change the gears, it is rather a suggestion to the system. The gear that you have your shifter in is the maximum gear that the car is allowed to shift to. If you are running in 1st, it can only drive in first. If you set it to second, the car can choose 1st or 2nd, etc.

Also of note: those are both very poor times. I'm not sure how eager I would be to post them to the internet.

One second in a quarter mile race is a HUGE difference.

At only 80 mph, for instance, one second is approximately 35 feet separation - at higher trap speeds, the difference becomes even greater.

- Don't kill wheel spin at the start of the race, dont be timid, try being more agressive.

- Also shift gears at higher Revs, the lower the gear the better.

- Draft if your behind, meaning stay closely behind the other car and overtake him when the time is right.

- Watch videos about racing lines, it will help if your really stuggling with turns.
