There was one review video where a Norwegian(?) test driver tried to achieve the top speed of 330kph and could only do so with the rear wing retracted...
When I used to do the standing 1 mile events in my 997.1 TT people were taping all body seams and removing rearview mirrors for the aero benefit, so yes I bet the sports package is detrimental to pure acceleration, probably bumps up the Cd a touch

See when I read stuff like this I’m totally confused .
my car is a 991.2 turbo s can, yes slightly heavier .
unprepped 1/4 mile beat time I have ever got is 10.6
car has xpipe straight through exhaust and is catless. BMC filter and tune running 640bhp
you guys are saying stick cars are running 10.1 , 10.3
Stick I was running 11- 10.9 seconds .
location is Scotland a drag strip which is unprepped. Just an old flat airfield.
cant get under 3 seconds on any road with the dragy timer . Makes me sad and I’ve spent thousands of pounds

Wouldnt the ET correction be apples to apples though because its the same magazine, same instruments, same method and correction?
I looked at the first motor trend article that clocked the turbo s at slower trap speed and that car has sports package. Would it be possible that sport package wing and splitter introduces more drag hence slowing the trap speed? The same is true for 135 vs 139 for when Matt Farah reviewed and documented the trap speeds. His car was the same sports package car vs one without but with lightweight package.

The applied DA correction factor would be different if the cars are tested in different DA conditions.
Since modern turbocharged cars can to some extent compensate poor poor DA conditions, DA correction factor can artificially skew the results. Good point about the sports package adding some drag though.

I have a very hard time believe ANYONE has done a legit 139mph trap speed stock… highly unlikely,, show me the draggy.
I was running 135-136mph stock and 140mph at stage2.

I am not as concerned about 9.9 vs 10.1 as I am concerned about the 4-5 mph trap speed difference. DA won't really account for that, that is a massive spread. It takes over 100 hp to go from 130 to 135 mph and the faster you go the need for more horsepower isnt linear. So to go from 134-135 to 140 is pretty massive. I dont see both being possible in the same car without some major changes in tune, gasoline used, tires, etc.
I takes about 100rwhp to go from 135-136 to 140mph…
135mph is about very low 600s whp (stock power)
140mph is about low 700s whp
150mph is about low 900s whp

This is why I think the hybrid 911s will not be very fast in terms of terminal velocity in a straight line race.

Or I think 200 lbs of weight also plays a role for each 5mph trap speed? maybe 400 lbs? I'm sure it does. That's how 720S with marginally more hp is able to achieve such higher trap speed.

Adding 100hp to a 650hp 3,600lb car is equivalent to a 480lb weight reduction on acceleration.
