Are we missing something in 1/4 mile times?

[SamHouseIII]

Per the GM Media highlights; 11 sec 1/4 mile times???? mines been upgraded and I'm only running a 12 flat???

VEHICLE HIGHLIGHTS

2. Offered in coupe and convertible models
3. 0-60 mph in four seconds
4. Top speed of 184 mph
5. 11-second quarter-mile ETs (11.93 with the automatic / 11.96 with the manual transmission)

There have been people to run those times and faster in automatics. I don't think anyone has gotten 11's with the manual without drag radials. I ran 11.72 manual stock with drag radials.

Welcome to the real world, where you can't just race off internet magazine times.

DA, Driving, Track conditions, car to car varitions, etc all have HUGE effects. Weather alone can swing times a full second. Track prep can too. Don't get started on drivers, as you can have someone in a stock zl1 running 14s all night if they can't drive.

What a magazine/OEM publishes is nothing more than what they got 1 time 1 day with 1 driver as a idea of where a car can run. Typically you find real world +/- 0.5 seconds of that but if you run in bad weather, high elevation/etc it can easily be 1-1.5 seconds more than published times.

I remember GM did put drag radials on the Auto and Manual 2012 ZL1 to get those times with a video. And yes, I'm sure drag prep and DA was optimal with probably more than a few other tricks of the trade to get a bone stock car down the track right. Add a serious driver in the manual car and I believe a 12.0 is do-able.

I ran 12.7 bone stock on my 3rd pass in the car in 2000 DA with factory tires at 32 psi with a 2.1 sixty. And I am not very good in a manual.

This had been debated repeatedly, but you need to listen to that video as well. Times were ran on stock tires. They also launched the car hard repeatedly on DRs to test the drivetrain.

The attached days 11 second quarter mile (11.93 auto and 11.96 manual).

But keep in mind a lot of times these are 'corrected' times which take over variables into consideration.

Plus i don't think they give that time with the manual using launch control. Wonder if the time would be better with launch control?

no launch control is a good way to run consistanly slow times.

basically this car is a pig to launch and it just plain takes a great driver in perfect conditions to cut 11's stock with a manual. I don't get enough seat time in mine to realy feel like I am nailing the launch. it is such a fine line between bog and spin I just kind of feel like i have to be mean to the clutch to get a good launch. the surface and temp play into it big as well.

there are quite a few poeple that have run 11's in auto's stock but not many manuals at all.

most people that want to run this car at the strip just run a drag radial to offset the launch issue. I think it is the weight myself.

I mean GT500 has the same issue. very few could put the 550 hp version in the 11's. the 13-14 has 662 hp and higher gearing. it runs crappy 60' times but pulls so hard on the big end that even the launch control will produce 11's for people.

True statement. The CTS-V manual Guys have the same problem getting their slugs down the 1/4 mile. Stock and Modded. I think the best I could have done stock would have been 12.2 - 12.4 on a 1.9 sixty foot and much better air.

Here is the thing about drag racing. To be fast, you cannot spin tires. It is all about sticking the launch and then riding it out. The stock tires are a little overmatched with the stock motor so a good driver can just barely get the engine to use all the power on the stock tires. If you mod the car and add more power without changing the tires you will run slower because it is much harder to stick the tires. With 835 whp the best I ever did on stock tires was 11.4 and that was with a second gear start and traction control on ptm 3. I let 2 pro drag racers drive my car and they could not beat my time, they both said, "you need better tires". With stock tires and 835 wheel I could john force the entire first 1/8 mile.....easy.

Good info. I don't ever drag race but my thoughts are an owner of a zl1 should know how to drive and how to launch. That's where I am at. I am new as well to the car and ended up with the manual. I probably would have went with thr auto of I coukd have found one with the discount but I got the manual for 43,200 brand new. Couldn't pass it up.

But always wonder when these magazines etc post these quarter mile times in the manual exactly how they are launching it. I watched one video and one guy launched two different ways. Watch the 2012 motortrend review of zl1. It is 5:51 seconds long. He says defeat traction control completely and launch at 2k rpm. Says not near as consisten but can yield faster times. He was able to turn a corrected time of 3.8 to 60 and think 11.7 In quarter mile. What does everyone think?

[JackalopeZL1]

I have run in the 11's bone stock, stock tires.. DA and track prep.

[Chrispy]

The quarter mile is all about the first 330 feet. Traction is king...

The GM guys had a track rental, lots of VHT and plenty of time to play with the cars.

They ran 11.90s on stock tires in good condition and a couple tenths faster on DRs.
