Hopefully getting it done before the weekend, it takes about 20 minutes. Stay tuned
nice!!!

I went out to the local track tonight and best time I managed was 11.0 @127 mph with a 1.74 60’ running Cobb stage 2 and cat bypass.

Plenty of wheel spin on the launch so I feel it would probably run mid 10’s with drag radials.

PS I also had a baby seat, diaper bags and all the fixins to keep a 2 yr old happy.

What car? Which track? Pretty amazing these cars, a 10 second car with barely any mods.

Figures there's a built-in adaptation program. Makes sense just from even a stock car point of view, as the clutch packs wear, the system has to be able to adjust. Probably cranks up the hydraulic pressure a bit to increase the clamp force to prevent slip.

Nice. I grew up in Gainesville, so I have a couple hundred runs down the dragstrip there. As you may know, track prep is about non-existant for test and tune nights there. No way you'd cut that 60' time in g'ville being rwd!

Nice work - I thought you'd crack the 130

543HP at the crank nearly 100HP gain over stock - impressive

Not bad for a grocery getter

It's scorching hot here at present. In three weeks COBB will release Pro-tune, and give me 4 months to work with it and when winter cools us off, you will see some really impressive stuff.

I'm already impressed - great gains - I look forward to the protune and cool weather outcome

and good on you for putting it out there. Just goes to show how good this 3L mill is.

that's pretty amazing especially considering your car is pulling timing everywhere based in the datalogs you sent me.

The car is adapting. I hadn't had the Akra cats on long and then added the stage 2 and logged it the same day. It seems to take a awhile to fully adapt. I have been racing a bit and the more you drive it hard, the faster it seems to become.
The cats were almost stock like quiet when i first put them in. Now they are quite loud. So they have definitely bedded in and made a difference.

My car was 55% waste gate duty on stage 1 and now is 64%. I can't wait for Pro-tune and get this thing in the 90's. There is no reason it can't get there and use the turbo's to their max ability. Its just time refining.

SPD: You are correct about the clutch force. Thats is what the PDK adaptive program does. It allows the clutch force to increase without slippage.

4 point 0: I am running 11.04 in the 1/4 mile on the road with all season radials and documented clutch slippage.
I dont think your headers are doing any more for your car than the Kline are doing for mine, In fact, I would argue that proper rubber, warm asphalt and a clutch that doesn't slip would probably reduce my time by more than .20 seconds. So, your car is fast with Vektor headers, not because of Vektor headers.. Oh, dont forget my car is also 325lbs heavier
