Hey,

I know GM rates the 2015/2016 Z51 0-60 acceleration at 3.8/3.7 seconds however watching acceleration videos I have yet to see anyone get below mid 4 seconds, no where even close to the numbers reported by GM. My question is do these guys all suck or is GM really exaggerating the acceleration? I still have a month and a half until I get behind the wheel to find out for myself.

 

manuf times are under ideal conditions after many attempts with their pro drivers. going out on the access road and flooring it is not going to net you "best times."

 

It's been done by some members here.

 

I sure hope the PDR timer is accurate. Here's a really nice launch on the side of a road in a heat soaked 2015 C7 auto where I ran a 3.6 zero to 60. I was very happy with a 3.6 on hot day and I'm hoping to make some passes at Royal Purple during the winter months when the DA is in the negatives. What I was doing was experimenting with launch control. The 'book' says to stand on the brake in a panic brake mode and floor the accelerator, which is everything against any drag racing I've ever done at the strip in other automatics.

Here is a 3.8 taken about 5 minutes before the 3.6

Nice going GOAT!

You gotta upgrade your PDR software so it doesn't look like there's moss covering your windshield.

 

Awesome job goat! Glad to see someone actually hit the advertised times I've actually heard that the GM testers were able to hit 3.5 seconds in the A8 Z51 but not consistently enough to post it as the offical time. Your 3.6 makes me believe that's true.

 

You have to assume that all the GM testing was done on a race prepped sticky track
On the street --NO you will never get those numbers----
On my modded E85 2014 A6 ( apprx 500 BHP ) the average on the street is about a 4.1 or 4.2---
Whether I have the TC on or off---OFF it spins horribly---ON it bogs---Takes a lot of practice to beat the time with the TC ON---

 

Well, I guess my bone stock auto that turned in a 3.6 (heat soaked, shoulder of interstate, hot day) is a figment of my imagination.

 

nothing you do can be verified, especially as not being downhill. did you measure the grade? or did you go by looks?

it can be done, especially with an auto, my wife can do it in an auto....but how can we know? i mean, even if you promise?

 

Dude, I turn 61 in a few days, and I'm too old to get in a pissing contest or lie on car forums. I just post the truth, and have a PDR video to back it up. It was ran out close to Baytown which is coastal plains and very flat. By the way, I'm not going to promise s**t to you or anybody else.

......and if want to get deeper with some sort of ridiculous conspiracy theory, how do we know the car didn't have a tune, headers, better torque converter, or drag radials? Oh, I hacked into the PDR program and made the PDR indicate -.4 from the run which means my hacking turned a 4.0 run into a 3.6 run. [sarcasm]

If you or anybody else doubts it, I really don't care, and I can be put on ignore for any doubters. At the end of the day it's all about trust. That's what makes the fast lists fun.

I also take offense that you would cast doubt on my PDR run just to solidify your position. Hopefully you're correct in one aspect, since my 3.6 was ran on an access road and isn't going to net my best time, I can hardly wait and see what my bone stock car can do in better weather, cooled down, and launched on a well prepped track.

 

Don't worry about it goat, tis the internet and Higgs is rolling with tradition. Besides, no one likes a Higgs boson anyway, too elusive. I'm a quark guy myself, a charming one.

Goat, do upgrade your PDR software though, the improvement is HUGE.

 

too sensitive. you take offense over 0-60 times?

solidify my position? yeah, thats what i am doing. because this is important and our positions matter.

 

Sorry if the big picture escapes you, so let me dumb it down for you.

It has nothing to do with 0-60 times, but the implication I would lie over stupid 0-60 times.

 

let me dumb it down for you also. YOU don't have to take personally that which is not personal. if someone in your life has recently questioned your integrity and you are hyper sensitive about it, ok i get it. but otherwise, let stuff go, buddy.

i didn't even look at the screen name of whoever I quoted, which it is safe to say, it was you. WHY didn't I? because I was making a generalization on a point you must have made and you took it specifically into your psyche. seems like a waste of time on your side....

i don't reply to PEOPLE. i reply to statements. all the same, when people reply to my posts, I don't see them as replying to ME. very few of us actually know each other personally, so how can any of us think anything is personal???

 

Looks like someone is super butthurt they can't launch their car as well as an old goat haha

Goat though if you haven't already you should do what others have said and update that PDR software I'm so glad they fixed the green potato cam effect.

 

yep, ya got me.

 

That's probably right.

I live in the east part of Houston, and my 2nd oil change is coming up soon in Sugarland (about 30 miles away), so when I get the oil change, I'll have them update the PDR.

 

wow and a noob too....how surprising.

 

My car spit out a 3.8 before but I threw that time OUT
If you read my post it says the AVERAGE times are 4.1--4.2---You can't judge an average time with one lucky run probably downhill or downwind--
An "old goat" is one who refuses to accept common sense or new technology

 

You're as ridiculous at the other guy. I tried it 3 times, threw out the 4.1 and kept the PDR vids of a 3.9 and a 3.6.

Why is it so hard to believe? This isn't a pissing contest, I just posted what happened. Why don't you and whats his face go to the different 'fast lists' and rag on their asses and make them prove their times or conditions?

So yea, this old goat ran a 3.6 time 0-60 according to the PDR. The car is still bone stock, the car was heat soaked, the weather was hot, I ran this on the shoulder of the road near Baytown which is pure flat lands.

Ha ha, all that power and you can't drive. So because you can't launch your car to get into the mid 3's, you cast doubt on my time and make up excuses why on the street I launched better.

YES you can get into the mid 3's bone stock. tblu92 is wrong. Just read the owners manual, and practice. It will take a few tries to get there, but it's possible unless you live in higher elevations. Baytown is around 40 feet above sea level.

Yes, a "young punk" that was proven wrong, casts doubt on my PDR video in order to solidify his poor launches, and can't launch his car.
********************

I will say this, I'm not really sure how accurate the PDR is. Here is a PDR of my personal best that was ran on my first run ever at Royal Purple (guaranteed flat land and not launching down hill). The 0-60 on the PDR is 3.91 and the quarter mile on the PDR is 12.21, however I actually ran an 11.91.
