For sure, gearing....no idea about the Vette, though...lol...

True.... But given the nature of the Z/28 I can see it not having a real high top speed.

I totally get the gearing taking mph off the top but if these #'s are accurate I don't quite understand the 0-60 time @ 4.2. It just seems to me that if I throw a 3:91 gear in the car, take 300 pounds off her, and have the hp/torque #'s we have been told that it should be sub 4. I know you don't time a road course car from a dead stop so I get it is irrelevant for the purpose of the car but I just find that a bit odd. I am not slamming the car, especially since this is all speculation it just seems to not add up to me.

500hp and 317 lb-ft crank hp/tq will break traction of 325/30-19" Trofeos while rolling in 1st gear at 10-15mph on a 911. Therefore it makes perfect sense to me that a car with smaller tires, front weight bias, and ~183 more lb-ft tq simply can't put down the power through 305's for a shocking 0-60 time.

And...if it has the close ratio gearbox, it likely needs a shift before 60 mph which will make the 0-60 time longer.

We have no idea if this speculated information is correct, and if it is, I just don't care. It doesn't matter for those of us who will use the car for its intended purpose.

Why don't you invest in a driving school? The Spring Mountain Ron Fellows/Corvette school would be great?

Here you go: http://www.springmountainmotorsports...riving-schools

The skills learned will last a lifetime and you don't have to feel left out of the conversation on here.

Hopefully this will help put to rest the guesses that the Z/28 will cost less than the ZL1 that I see in almost every other thread.

According to GM/Media specifications, the gearbox ratios for the 2014 Z-28 and the 2013 1LE are identical, apparently they are going to use the same TR6060. Also, the first four gear ratios are identical for the ZL1, Z-28, and 1LE, the only difference is gears 5 and 6, with the Z-28/1LE having .74 for 5th, and .50 for 6th, with the ZL1 having .80 for 5th, and .63 for 6th.

Is the final drive gearing known for the Z/28? Sorry if I missed that.

Actually, now that you mention it, Porsche is building a new facility in the City of Carson here in SoCal...Not sure what all the details are, so far it's like a driving skills facility for new Porsche owners and what-not...Not sure if it will have any offerings for the general public yet....It's under construction now...May look there in the not too distant future...

^, yes thats correct....3.91 rear axle gear ratio, and with 19'' square tire set-up over the 3.73 rear axle gear ratio<standard trans> and 20" tires on the ZL1, with lower fifth and sixth gear's, it's going to be much more of a gear jammer and selective in keeping in the power band for the layout at hand. It's going to be a shifting, high winding wheel mans car for sure...

FWIW I was playing with my EFI live and recorded a 0-60 time of 4.2 with my cam headers and intake on my 11SS, and I'm far from skilled when it comes to launching. I would think the lighter Z28 would have no problem matching it with bigger tires and lighter weight.
