A) 1.74 60 - 12.11 @ 113.35
B) 1.79 60 - 12.33 @ 114

A) .05 better in the 60
.22 faster ET on top
.65 slower MPH <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I know, car A stepped on the breaks. Nope he didn't.. What other reasons could cause it?

Generally, the faster the 60' time on a car--the faster the ET. I know it is frustrating if your MPH on a car is faster than another car--but yet the other car wins. But to run a fast ET period, you have got to get the 60' time down. Also, the shift points of a car can affect the ET, if a car shifts sooner than the peak horsepower/torque, etc., this will affect the outcome. Also, if a car weights <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" /> less than another car with equal power, then the lighter car will win the race. These are just a few suggestions to explain what happen. I hope this helps and maybe somebody else can explained it better. Kent.

Car A is making better use of the powerband. The right gearing/converter combo can play huge here... Like Kent said, shift points, weight, etc. will have effects too.

Car A being me and Car B being Terry Burger, it's obvious who's going to win. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

You can also spin past the 60' mark. A .10 in the 60' often amounts to .15 in the 1/4. And in some cases, especially if the car is undergeared, a little spinning can result in more MPH by getting the car in the powerband faster.

Car A: Auto and heavier (00 Z28)
Car B: 5 speed Lighter (300Z)

Confusing issues for me so please correct me if I am wrong..

.1 in 60 = aprox .15 on top end.. So 1.74 to a 1.79 = aprox +.075 on the top end with equal mph for Car B..

1mph = aprox .1 in the 1/4.. So +.65 mph = -.065 for Car B

With the above:
A 12.11 of car A
+ .075 (result of the 60)
- .065 (result of the mph)

= 12.12.. I know it is not an exact science like that, But I am trying to see where the extra .21 was for car B..

By the way, Sam Track, Same day..

Look at your short track times ... bet you car A is faster in MPH as well as ET on the short half of the track ... Car B is playing catch up at the tall end of the track.

So your saying that the .05 difference in the 60 could really be more than that at half track? From half track car B starts to pick up better?

Run 1) 1.758 60' 12.466 108.86

Run 2) 1.724 60' 12.464 109.98

Run 1 is 3.23 gears, Run 2 is 3.73 gears. The difference was at half track Run 1 was 87.2. Run 2 85.9
