Realistically for a stock manual trans car on oe tires in average warm temps, heat soaked engine, average track prep and average driving skills, is 12.3 to 12.0. A auto trans car realistically under the same conditions 12.1 to 11.9.

I absolutely agree 100 %
And with the auto car being much easier to launch it is easy to replicate those times back to back , I always joked with my friends that I should come back on SATURDAY' bracket racing day because my car was so crazy consistant
if the grip and air was good , 11.8 ,11 9's all night long
if the grip was bad and the DA was bad ......12.0 12.2 all night long

I run my 1LT manual base car with the Zf1 pkg for the Z51 size OE tires with a borla xpipe , conservative 93 octane tune, self ported TB, 180 stat and on a 60 degree day about 1200 DA I just ran a 11.7 @ 121 MPH. Thats with a not so bad or good 1.97 60ft time.

Yep my LT1 with a CAI and a 93 tune ran 11.9 on a 85 degree day and 2 000 DA . I am confident on a cooler day with better DA it would go 11.7
Next up on my list is to install my Edgy Vette ported manifold and throttle body and a another more aggressive tune ,

Last will be headers and then I am done as an 11 second on stock runflats grocery getter is fast enough for me
I dont want to loose the great drivablity and reliability that it has now

I am there now Dave, thats it, I am done, car is fast enough and so easy to put the stock xpipe back on that I kept, put the factory tune back in thats saved in my SCT X4 tuner.

Not as rare as you might think , here is my LT1's most recent time slip on factory RUN FLATS on a track that has marginal grip at best .. so bad that this and several other runs just like it were all done with Launch Control
And the DA sucked ....

I consistently turned mid to hi 1.7s in mine using launch control with the MPSS ZPs. I've been told several times I could improve that by not using launch control and learning a better launch technique.

ETA: My best was a 1.731 but that was on DRs.

Big , I get told the same thing but as long as we have bad track prep at our Test and tune nights I am just sticking with the launch control . I am out to run a few good runs not set any records

I still cant believe that the car I drive to the track pops off 11 second runs and then the next day I am taking it to get groceries lol lol

Like some one stated above , we use to spend a ton of money just to go high 12's .....

My statement said low 1.7 60 ft times (like 1.71) . What size tires are you guys doing these on ? grand sport size, Z51 size and with auto trans cars I assume. I have trouble with my M7 car on a 285 30 20 MPSS. high 1.90 60 ft times with all nannies off

Same tire as you and yes Auto .....dont be a hero with a stick car and put the nannies back on ...

I am confident I can get low 1.7 or high 1.6 with the runflats

We have been struggling with track prep and DA down here in the south , been running around 3000 DA . It finally dropped down to 1200 and we got rained out . Now it's real good but the track is closed until April

Running stock a 1.79 and 11.9 with a 2000 to 3,000 DA and crappy traction is impressive by anybody's standards

What I would give to be back at my old track , Atco raceway ......

We will gett a few months of good weather when the track opens back up in April.before the heat and humidity settle back in ..but we cant do nothing about the traction ....

Dave
