while I know nothing about porsche tiptronic, I do know a bit about drag racing. How many competetive stick shift cars do you see in drag racing. Hardly any at all

Awesome!
Now those times are getting truly impressive 
After running shanes car to high 130's, I knew your car would be faster with the manual through the 1/4, mph anyhow.... And that was already a sick ride.
It's funny about the 60-130 thing... We've actually seen improvements in times starting from 1st gear in some cars vs. just 3rd and 4th. They're all a little different.
Now, get those bling bling rims off there and run something that has traction

As he said, 'two cars, making EQUAL POWER TO THE GROUND', the tip would be faster.
That immediately implies that the tip would require more power to the engine, to make the same power to the ground.
We just did Shanes car, 997tt tip with the same gt3071r package as Keith, and at the same boost levels it runs 139mph through the 1/4 mile vs. Keith's running a few mph higher...
So, same power at the crank and the tip is slower than the manual.
Even on the dyno, it was taking about .15 bar more to make the same power to the wheels vs. the manual, and that's about 37-40hp difference between the two. We figured it was about a 6% loss to the ground with a tip.
make sense yet???

Although not relevant to the 60-130 time, the TIP shifts into 4th at around 135mph and the rpms drop to 4900-5000 where it dies off compared to a 6speed.
So in reality, the 6spd is only faster at 140+ mph

it isn't so much power as it is reaction time in the tranny. 1/4 mile isn't about speed, the lowest time wins. Which means that you can have a more powerfull car against a car with less power but better gearing and tranny and in the 1/4 the better tranny car will get the best time. Since I assume these cars require 2 shifts to do the 60-130, each shift in a stick versus an auto you probably loose a tenth or two per shift. That equals a lot of time.
Try to run a 5 speed stick in the quarter against a 3 speed auto set up to run out of gear at the end of the 1/4. The auto will beat it in time, even though it's trap speed may be lower.

May I also ask...How is the turbo la lag with G30s on TipS ??? and from which RPMS did you launch Shanes car in 1/4...???
How do TipS works overall with bigger turbos ???

Rep Power: 66 Yes...but how come then VTG TipS is faster then manual in 1/4 my previous car did 0-60 in 2.4 and 0-100 in 5.9...10.4 at 132.9 in 1/4...I didnt see any manual running those times yet

yalmutawa: Will be building my motor and doing the cams and heads in time and upping the size of the turbos and intercoolers. Shooting for 1000 whp.

hope you're planning for axles and etc.... plus some serious clutch and transmission modifications.... otherwise it's power but not "usable" power. a daring project nonetheless.... keep in mind that kim's SPI build was in the 10's for the quarter mile running stock axles and etc... so just plan on replacing stock components after a while.
naked ambition, though.... congratulations.

keithta, congrats on getting some really awesome times out of your car with your Vbox. I can imagine how great that felt to get all the issues resolved and have it running tip top. I know how it feels to run sub 6 second 60-130mph times and it is a very cool rush.
