GT PP 0-60 times.

I think some of you guys with three seven three need to change your shift points to much sooner than redline.

Shifting reduces time considerably. Measured on my VBOX I am usually in the .5-7tenths range. Especially when you consider the amount of time it takes to achieve full velocity and recover from the load change.

If you achieve a 5.2 by shifting into 3 gears, subtract the shift time from the 3rd shift. In the case that it might have taken you .7tenths that means you did a 4.5ish 0-60.

You can't do a 3 shift to 60 and think its even remotely accurate. If you had to shift because of 3.73 and tire diameter then having 3.55 would be the next best choice.

A tune should be able to solve all these issues including any inaccuracy in the speedo calculation due to tire size changes, I am sure most tunes would increase RPM by at least 500 too.

Youtube: search 2015 Mustang 0-60. Find the video labeled "Tuned EcoBoost Versus Stock GTs 0-60 & More"

In this video they race a non-PP GT with 3.55 gears, PP GT with 3.73 and a tuned Ecoboost.

The 3.73 PP GT consistently pulls on both the Base GT w/3.55 and the tuned Ecoboost.

3.73 is going to provide the best acceleration. Unless 3.55 and 3.15 cars are able to stay in 3rd gear passing the traps in the 1/4, if all cars have to shift an equal amount of times in the 1/4 to 4th gear, the 3.73 car should be faster.

For boosted application I think 3.55 is the best choice if you are running out of gear in 4th for 1/4.

I had to shift into 5th every time going through the 1/4 traps when I had my 2012 3.73 geared GT on stock tires. My stock 3.15 geared auto was every bit as quick as my modded 3.73GT at the track.
The 3.55's are going to enable you to stay in 4th going through the traps unless you go taller tire and or extend the rpm via a tune. I'd expect the 3.73 to shine a little from a roll against the 3.55's, maybe up to a car length. I don't think faster is the term but more of a slight edge from a roll. The video you are referring to doesn't actually show the 3.55 car race the 3.73 car directly...
Anyway 3.55's for FTW overall :first:

I tried out the track app for 0-60 on my GT Premium 3.55 with the 20" wheels and it recorded a 4.8 the first time out. I had been out driving in the mountains and the tires were only heated from that driving when I found a nice long flat straight away. This was just in Sport+ mode so the traction control kept the tires to a brief chirp at WOT launch.

Manual or auto?

searching through his posts you will find that he has an auto.

An average person can shift gears in 0.5 seconds! Average automatic transmission can shift gears in the range of 0.2 to 0.25 seconds! Wait for it, A DSG transmission can shift gears in 0.008 seconds! So if the mustang had a DSG transmisson with proper tires it would hit 60 mph in 3.816 seconds which i m assuming a gtpp 4.4 sec 0-60 and a pro driver shifting in 0.3secs with 2 total shifts lol

With this information, I agree. 3.55 overall is probably the best gearing, especially for the 1/4 since 3.73 run out of gear around 112MPH.

I recommend PP with 3.55 option. With that said, 3.73 should have the fastest 0-60 on a 2 shift.

The automatic doesn't have launch control? How does the Auto launch?

Don't need no stinkin' PP and 3.73 gears. I ran a 13.08 on first pass of the night. Car is stock with the exception of catback. Heavy ass fully loaded 2015 Mustang GT Premium w/a booster seat and a forward facing car seat in the back. 20" Foundry wheels with the Pirelli P Zeroes. 3.31 rear gear. MANUAL XMISSION.

Thought about going to 3.55 back in January, but was like "Nah, I'm too alpha".

But seriously, I've already had a high strung car (2013 STI), 3.31 is fine for racing. Also, don't want to run something like a 3.73 when I Whipple this bitch.

IMO you buy the PP for the 4k Brakes, and better cooling, etc. But yes 3.15 Auto stock can do 12.5x @ 112mph.

 

[Vile_the_Bastage]

Yeah, the brakes are worth it. But I HATE huge wheels with a passion. I put 18s on my car for the winter with some fat rubber and loved the way it looked. I'm only running the 20s now because my summer wheels are on them. I'll be selling them this winter and buying another set of 18s, which I couldn't do with the huge Brembos.

I have a manual but i m guessing you put it on drive then sport mode hold break all the way down, rev the car up to whatever rpm you need and release the breaks!

 

[Sasuketr]

The lunch control in the manual cars actually serve no purpose than holding the selected rpms for you! But your foot is all the way down, you can hold whatever rpm you need without using the lunch control!

Nice time given the 20 inchers and added weight! That is the first time I've seen someone post a 1/4 mile run with the 3.31 manual 15' GT.
What was the DA and your 60ft?

The 2015 GT stang should be capable of at least a high 12 sec 1/4 regardless which rear gear. To be honest I chose the 3.55 option because the car feels a lot more satisfying (sotp) in every gear, at any rpm and throttle position when you hit the gas compared to the 3.31.
