I havn't seen to many times posted on track times, but I was surprised to see a 12.xx from the car. Untuned it ran 13.38 106.73, installed the tune and dropped to 12.80 @ 109.78, 30 minutes later.

Pretty good drop for everything down to the tire pressure being stock otherwise, I was impressed with the times for such a heavy car, I thought it would hold it back more.

Going in for ARH headers and a Vararam, then it's back to the track. All in all I am impressed with the feel of the car, nice driver.


Obviously there are many variables, DA etc, but what are the common ET's for these cars stock-tuned stock-and bolt on's?

thanks

Good times but no longer "Bone Stock".
That would have been before the tune.

Yes that's pretty fast for sure. I knew once the weather got a little cooler that the cars would pick up a little more.
My prediction for the quickest bone stock 2010 SS in good air is somewhere in the 12.6 or 12.5 range (maybe low 12.4s with just tuning?).

Beat me to it..

hense "bone stock, tuned" ? I thought it was pretty clear.


So that's about average for these Marc? I asked some other guys there with Camaro's last night, but no one had a sure answer, and I have not followed these too closely yet. I was more concerned with before and after the tune, then the actual ET numbers, but I would still like to know out of curiosity. Nearly a .6 drop in ET shows just how much these are held back.

what 60 and what kind of tune since you said you installed it at the track?

nice times, I didn't think these things were going to be as fast as a forth gen, but so far it looks I am wrong.

Doug @ ECS

2.05 stock, 1.92 tuned. I don't know if it was the best technique, (foot braking to 1200rpm with a fast roll in on launch) but it was the same launch each time. I'm sure the guys that practice it for more then a few passes will put down some better times, this one only has 1xx miles on it now, and wont stay stock long enough for me to keep trying different things.

EFI Live for the tuning.

I thought it was pretty clear too, but you can't expect too much out of the Interwebs.

Great times! It's astounding how much GM reined these cars.

Doug @ ECS

Thanks, the A6 is a torque management experiment I think.

Nice times for a tune only for sure

how did u tune it at the track? don't u need it on a dyno to tune it, check A/F, and other stuff?

They could have easily dyno tuned it on a dyno so they had the file stored on a computer, then put the stock tune back in to make a pass or two, then put the tune back in from the dyno they previously did.

Or maybe they tuned it on the fly at the track. They do make wideband gauges ya know My bet is on them doin a prior tune tho and just loading it up to see how it effected the ETs

Doug @ ECS

The tune process was done prior to going to the track, returned to stock-ran, then tune down loaded and ran. It picked up about a consistent 20+ rhwp, and even more torque, across the entire band.

was this the same car that was in GMHTP last month and this month? it ran a 13.38 also, thought that was a bit of a coincidence... if so, that car gained 150tq @ 3300, thats alot of tq management...

No. Indirectly, the dyno does nothing as far as the tune is concerned. It only reads the rwhp/tq. You need a wideband O2 and laptop w/tuning software to tune the car. The dyno is the place where it is normally done because the tuner doesn't have to actually take the car up to 100+ miles per hour as he works, among other reasons.

Some people argue that the street (and the track) is a better place to tune a car. Dynos are just much, much more convenient and gives the power output numbers. But, as we all know, the numbers don't mean jack. It's the times that matter.

I think that the 13.3 that you guys ran in stock trim is roughly the average, one or two have touched 12.9s and others have gone only 13.5s (depending on usual elevation, temp, fuel load differences etc.).
One of the 2010s you'd spoken to was my friend good Steve (there with his girlfriend Steph's Cyber Grey SS), they also ran in the 13.3s bone stock so the car obviously in need of some tuning.






It might be LOL, my C6's A6 was pretty bad before tuning/TM removal and I think the newer ones (LS3 C6, G8 and Camaro) are even worse!

Doug @ ECS

No, not this one. We are working with them on this car for it's final build. They are following the track and dyno steps from stock to stock tuned, then ARH's-Vararam-160 stat, then.... well you guys will see.

As far as a 150 ft lbs of torque increase from tuning, if it's on the internet or magazines, it must be true...


Nice guy, I think he ran 13.8 & 13.6 on Tuesday, but he might have stayed longer then I did.

Thanks for the info, I figured you were up on these things.

i said 150 at 3300... it went from 160 to 310... heres the chart:

True, I went back to confirm and they actually only hit a best of 13.4 (with a 13.6 and 13.5 as well) but he was also running almost a full tank of gas and didn't play with tire pressures at all.
The cars are heavy but the potential is certainly there.
