wow the auto is a lot lower then the manual...................

 

Not being able to get 1:1 gear on the auto how reliable can the #'s be?

 

Isn't there a 4th gear pull of a M/T somewhere?

 

4th gear isnt 1:1

 

Numbers are just numbers. It's the improvements that tell the story. It's still picking up 20whp from the stock tune....

 

I know that, but someone posted a 4th gear pull anyway, but I see now, the Autos have different gearing. Forgot about that. Oh well, it's an auto, there's going to be some loss anyway, unless they somehow figured out how to make a lossless A/T.

 

This car was in 4th as well

 

Nice gain, did they mention the octane used on both runs?

 

Ratios of manual vs automatic gears are apples-n-oranges. See comparison below:

(manual transmission in parentheses)

1st 4.17 (3.66)
2nd 2.34 (2.43)
3rd 1.52 (1.69)
4th 1.14 (1.32)
5th 0.87 (1.00)
6th 0.69 (0.65)

From Motor Trend on their manual transmission 2011 Mustang GT dyno run (note how the lower gear ratio results in lower rwhp & rwtq numbers in their dyno pull:

3rd gear (1.69:1)
rwHorsepower: 365.26 hp @ 6600 rpm
rwTorque: 335.27 lb ft @ 4500 rpm... See More

4th gear (1.32:1)
rwHorsepower: 377.99 hp @ 6500 rpm
rwTorque: 351.44 lb-ft @ 4400 rpm

 

We need to quit worring about dyno's and start getting more auto's to the track to see if these cars can really run high 12's as the other and only auto so far said he did. With these dyno #'s it is getting hard to believe.

 

American Muscle could only get a 13.0 out of their automatic, so it sure looks like the numbers are correct.

Horsepower solution got a 12.97 @ 110 with 87 octane with their auto. They are going to run 93 next and test it.
