ZL1 in big trouble? Q&A with SVT Chief Engineer today...

![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
In 2012 the Track Pack includes the 3.73 gears (to replace the standard 3.55s), right?
But for 2013 I'm assuming that the package no longer includes any optional gears, just the standard 3.31s and that's it?

Sorry not sure why it didn't work in this post. The same link still works in post #82 which is where I originally posted it. Here it is again.

Yes I don't think it's an option as of right now but ford fans have been complaining about that so maybe they may add that eventually as part of the package. Not everybody cares about going even close to 200mph. Most ppl will give up top speed for better acceleration. The 3.31s are a benefit in certain ways though especially since it allows the Shelby to complete the 1/4 mile in 3rd gear. 1 less shift

Didn't they change all the gear ratios, besides 4th? Maybe I'm remembering wrong, but I thought it was all new gears in this car, so you won't be able to compare a 2012 to a 2013 with different rear gears. Either way, rear gears on a car like this aren't going to make much of a difference. Changing gears in a car that makes 500ft/lbs at 2000rpms is nothing like doing it in a higher revving N/A car. And when we are talking about a 120hp difference between the '12 and '13, it's laughable at best to think the gears are going to make it a close race.

I'm gonna guess they're gonna offer something steeper at some point for people that are more focused on road course racing.

For the first time the Shelby GT500 will utilize a 2.66 close ratio first gear thus eliminating the dreaded “nose dive” from 1-2 shift and will get the GT500 to about 62 mph at 7000 rpm . In fact every gear besides fourth was optimized

2012 with 3.73s (optional) and a 2.97 1st gear.
2013 with 3.31s and now a 2.66 1st gear.
Yes, that extra 100-120hp is still more than enough to erase that gearing loss (and then some), but it's not as if one can look at the 2012 GT500 and just say "cool, the 2013s are going to be a full '100-120hp quicker' in the 1/4 mile" because it could be a little deceiving.
In other words, it gains lots of acceleration power over the 2012 but gives some of that acceleration back in gearing.
This is assuming both cars having the exact same rear tires as well.
And then there's the new traction/launch control system to factor in as well.

Honestly though, how much does that really matter when we are talking a 670hp 600ft/lb car? I have a feeling with all the new stuff in the car it's going to be more than 100-120hp quicker in the 1/4 mile.

True, but let's not dismiss/overlook the importance of gearing for good acceleration...
2012 with 3.73s (optional) and a 2.97 1st gear.
2013 with 3.31s and now a 2.66 1st gear.

3.73's + 2.97 1st gear was worthless. The '13 make the '12 peak torque at 2000 rpm.

Cool car and I think I'm surprised Ford's allowing "orders" so soon. The funny thing I noticed in the end is, when I went looking for a match, it showed me a $45,465.00 2013 Mustang Boss 302. That's all good, but c'mon... looking for a 2013 GT500?? Who's "settling" for a Boss 302??? Not me.

You can still go a little smaller on top, but you can always do a lower pulley as well ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
A lower pulley, thorttlebody and header back GT500 will make 700+whp.
That is a lot of power with a couple very minor changes.
A heads, cam upper and lower LSA does not even get you that.
