So I took my maxima to the track a few weeks ago and ran a 14.290 at 101 MPH

everyone was like that is a trap speed of a 13's car so I went back today

I weight 3520 BOTH Visits

Only difference in the car is new motor mounts

This is my first 14.290 Second

Temp - 83F
R/T - 1.1011
60' - 2.273
330 - 6.146
1/8 - 9.325
MPH - 79.16
1000 - 12.029
1/4 - 14.290
MPH - 101.32

This is todays run

Temp - 78F
R/T - .606
60' - 2.220
330 - 6.121
1/8 - 9.299
MPH - 78.97
1000 - 12.014
1/4 - 14.290
MPH - 99.88

Can someone explain to me how...
A car weighing the same, on a colder day, at the same track, with better motor mounts, runs better distance times then a previous run yet has no speed.... please can someone please me how that is even possible...

how I can get to every location faster then the previous run, yet my MPH is lower AND I run the same damn quarter...

 

MPH is typically related to high RPM power. Get a dyno.

 

tailwind ......

 

Its called density altitude. You need to input the weather conditions from each day into here to see how much power your car was making those days.

 

This information may be wrong... but using averages on info not on the slip this is what I got for yesterdays run

Relative HP = 100.4%

The first 14.290 I ran was

Relative HP = 100.1%

So you can see

First Time run The information (from wunderground.com)
Temp 83F (Timeslip)
Absolute pressure 30.06 inches HG
Relative Humidity 55%

Second time run
Temp 78F (Timeslip)
Absolute Pressure 30.12 inches HG
Relative Humidity 73%

(Used Average for pressure and Humidity)

 

The differences in your 60" times between the two runs could also be a factor. Your higher trap speed run also has a slower 60" time...I will generally see the same thing, a higher trap with a worse 60 foot.
