Predictions on performance

[Mrzero]

Here are my predictions on the 0-60 and 1/4 mile times for the handling package cars, manual and automatic. What are your predictions?

MANUAL:
0-60: 4.1 seconds
1/4 mile: 12.1 seconds at 118 MPH

AUTOMATIC:
0-60: 3.8 seconds
1/4 mile: 11.8 seconds at 121 MPH

While I have no predictions as my crystal ball sucks, I've been wondering if a base A10 car might run a 11.5 second quarter (or better?) right off the transporter....

 

[jake_zx2]

I think the manual times are spot on, but I think the auto will be faster. My prediction for an A10 handling package car is a LOW 11.7

 

[ChitownStang]

I don't think the handling pack will be faster than non on 1/4 mile or 0-60. More weight.
Handling pack shines on the turns.
11.5 is my prediction but I'm optimistic since I ordered one! Ha

Weight difference will be negligible (only things that will really weigh more are the splitter, wing, and splash shields), but the HP gets stickier tires and, more importantly, smaller tire diameters

GT350 is 1-2 tenths slower than the R. The HP will be faster for the same reason

 

[ChitownStang]

Smaller tire diameters on the HP, they are both 19's?
Bigger tires also weigh more
Is the PP2 faster than a PP1 stick?

They are both 19” wheels, but the tires have a shorter sidewall, thus shorter tire diameter

Bigger tires do weigh more if they’re the same tire, but Cup2s are lighter than Sport4Ss, so the difference from size is likely negligible. Ford has also said the “bird nest” wheels are actually lighter than the standard wheels, despite being bigger

PP2 is faster than a PP1 stick. IIRC, it has actually tested 2 tenths faster

Ok, I learned something new.
Thanks

Using my 2019 Bullitt as a reference, you will have a VERY, VERY hard time doing the 1/4 mile under 12.5 seconds. Since the only significance difference is the gearing in the tremec which is close to the Bullitt. I found it very hard to launch at the dragstrip either bogging or tires spinning.

I will get many responders saying different. Post if you have an 18 up with a stick stock and actually did the 1/4 mile. It's tough.

12.5 is about the average time for a good driver in a Bullitt. I think the fastest stock time on record is a 12.4 for one

But the gearing in the Tremec is NOWHERE near that of the Bullitt. In fact, there’s another whole gear between 1st and overdrive. Not only that, but you also get a more precise shifter that doesn’t need extra patience to get into 3rd. And you’re also forgetting that we will also get the handling package, which has stickier tires and a rear tire size that essentially equates to upgrading to a 4.10 rear gear ratio. Not only that, but Mach 1 also gets the option of an automatic, which will be even faster

I think OPs time estimates are pretty accurate, if not a bit conservative. Keep in mind, a GT350R runs 11.8, and in the context of straight line performance, there really isn’t much separating a Mach 1 from a GT350

Cup 2's aren't going to be faster in a straight line than the PS4s

What makes you say that? I mean, it has about the same sidewall stiffness, but smaller diameter and stickier compound

If Cup2s don’t make a difference, then why does the GT350R consistently run faster than the standard 350?

 

[Labradog]

Ford has said that. Look at the GT500. The advantage with Cup2s is their lateral grip.

 

[jake_zx2]

That IS the case for the GT500, because the overwhelming power and weight of the car mean that the change in tire compound isn’t enough to compensate for the loss in sidewall stiffness, and the shorter tires are actually a detriment to the acceleration because the car already has too much power for the gearing on it

but that’s certainly not a “one size fits all” situation. Once again, look at the GT350 vs GT350R. The R consistently runs faster 1/4 mile times, because it has stickier compounds and shorter tire diameters

 

[GreenS550]

First of all let me say that I am ordering a new Mach 1, manual transmission. So, I am excited about the stick.
But the gearing is very close to the Bullitt. If Ford uses the gearing from the Tremec in the Gt350, overall comparative gearing looks like this:

Bullitt Mach 1 Difference Mach 1/Bullitt
1st: 3.237 3.253 100.5%
2nd 2.104 2.233 106.1
3rd 1.422 1.611 113.3
4th 1.0 1.243 124.3

So, you can see from this that the equivalent final ratio of the Mach 1 vs the Bullitt would be having a 3.75:1 axle out of the hole in 1st. No real significant difference.

This is why most folks are going to have a very difficult time doing more than a 12.5 in the 1/4. When I was at Milan, there was a guy there racing his GT350 and just barely got under 12.5. He had drag radials as well.

It is the launch with the long gearing that makes it so tough. That said, my likely ONLY mod will be replacing the gears in the axle with 456 or something like that.
