Understanding MPH and ET times variance?
 

I'm just trying to figure out what plays a role in what. Why is it that you can have a really slower ET time and still get the highest MPH. I'll give a couple of examples:

Last Year's best:
This year's best:
Other times from this year with high MPH:

Reaction - .0799
60 ft - 2.7260
330 ft - 6.8200
1/8 ET - 10.1770
1/8 MPH - 72.81
1/4 ET - 15.3699
1/4 MPH - 95.78

Reaction - .2629
60 ft - 2.2511
330 ft - 6.2371
1/8 ET - 9.5549
1/8 MPH - 73.56
1/4 ET - 14.7209
1/4 MPH - 95.77

The second last one is probably the most dramatic of being about .8 second slower, but netting my highest trap speed.

When you spin the tires off the line your car obviously runs a slower time but nets a higher mph at the end of the 1/4. As you can see in the run on the highest mph, your 60ft was 2.7, while all the other 60fts are around 2.2. This means you spun the tires off the line, which made your time slower and your mph higher. Got it? There's also many other variables like weather and on how well you shifted.

Running a slower time will give you more time to make up speed. For instance, if you was racing a car that was in front of you by 2 or 3 cars but both cars are excellerating evenly, the car in front will run the better time, while you get 3 more car lengths to make up a little more mph. I've seen a lot of cars trap 3 to 4mph more on their slower time. This is the reason why your 1/4 mph is the best way to judge your horsepower. Your mph should only go down a little with a better time.

Hmm interesting ... So MPH is the best way to figure out HP output. Also my second last set that I added and my last set of numbers say that my last set of number although running 0.65 faster and netting almost the same MPH i was shifting quick and should be right around where I should be?

Also from those MPH numbers what do you guys guess my HP is (given a car weight of 2470 with driver and some tools in the back)

I'd say 140rwhp
