GT PP 0-60 times.

[96Mustang460cid]

Yeah, I'd have to agree with you on that point. I'm curious about 1/4 mile also (haven't been yet, but plan on it shortly), if at the end of the 1/4, shifting into another gear might be a factor.

With 3.73's, I'm in 4th gear when I cross the traps. Don't recall specific RPM, but, assuming the same transmission gear, the 3.31's will be 12.6% lower RPMs and the 3.55's will be 5.1% lower RPMs.

Have a good day!

Good info, thanks Michael! I have a neighbor down the street (car junkie & gear head), he ordered his Mustang with 3.73's & manual. He should be getting it some time this month. We already agreed to go to the track. Mine has 3.31's, so we'll see how they compare!

I'm experiencing all of the same issues already mentioned. I have nothing but a Bama tune on an otherwise stock GT PP manual trans Mustang and can't seem to do better than 5.2 seconds. Haven't launched over than 3k mainly because I get nothing but wheel spin through 1st and most of second. Can't avoid the shift to third either.

It's all about the tires. The main reason why I got a PP GT besides the black wheels, cobra brakes and gear ratio was the summer tires not all season.
I put drag radials on the rear at the track and with my bolt ons got 3.9 0-60 times.
This is with a tune and full exhaust with the blowfish tranny bracket (best mod by far).
With my stock tires on I get high 4s after hearing the tires up.

Take solace in knowing that all cars have this problem, so when your next to the C8 corvette and find that you'll get to 60 in 5 seconds and the vette will do it in the 3s know that isn't true.
Depending on the vette's driver he might be in the high 4s or even higher.
When motor trend does 0-60 times it is after dozens of runs in the ideal conditions trying to get the most speed as possible.

That's some good times man. What tune are you running?

Back to the topic of the thread...my best as of last night is 5.6. I guess there are some guys over on the V6 thread getting faster than me!! But I did try on some slippery asphalt and spun a lot.

On board computer is off by about a second on PP GTs

I love how people compare 0-60 times as if they only race to 60 lol. In a real race a PP car will clearly pull away at higher speeds. It makes me damn happy I choose the 3.73's. I've also accepted that the slower times are due to wheel spin but we all know once you hit third and she hooks she's gone!

I agree with you that traction is a big factor. My brother's 13' V6 3.31, dyno tuned full exhaust auto would hang with my tuned catless 3.73 geared 12' 5.0 up to around 60 on street tires but after that I'd walk.

I don't agree that your 3.73 car will clearly pull away from the lesser geared 5.0,(all else equal)... A car length or so maybe against the 3.31 car, and negligible or half car against the 3.55 lol, definitely not walking. You guys with your PP cars, you think as if 3.73's add 100 horse...

3.73 with proper traction (slick) slightly taller tire should be optimal N/A set up at the track.

3.73s are quicker off the line... it's as simple as that. 3.55s have better top end spend... 3.73 would be more desirable for track days because of better acceleration coming out of turns, especially sharp turns. It's really not that big of a deal.
Let's not attempt to divide the Mustang brotherhood. We get enough crap from little brothers GM and Dodge. Why cause an inner struggle?? So pointless.

Not trying to cause ''inner struggle'', I just find it irritating how people with 373's think their cars going to easily walk away from GT's with longer gears where in reality they might have a slight edge.

I'm strictly speaking from a drag race standpoint on stock tires.
3.73' are quicker off the line, traction permitting and why I also mentioned 3.73's being optimal running slicks...
3.55's will permit more traction in first while not requiring the shift into 5th before the traps.

Yes, 3.73's are better for digging out of sharp turns but not optimal for all tracks like with longer straights.

3.31's not enough gear without more power added and make the car feel neutered in daily driving imo.

I believe we have the same exact car :cheers:

Let them think that. I own a '15 PP GT, but I know the biggest difference comes from the driver.

I need to make friends with a PP dude. It would be fun and interesting to try this out. Referencing the "What things weigh" thread, the non-PP weighs about 70 pounds less as well.

I wouldn't doubt that one bit! Few more things added with the PP that I would assume add weight to the vehicle.

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.
