Top speed in the mile
#41
Compared to similar powered cars that have run the 1000m here in Australia, that's pretty good.

I went back and put the atmospheric data into the drag computer I have and the DA for the day was 3980 ft It was dead-on with the morning's run and it showed the wind was killing the power way more than I figured.
I queried it for 1000m since it was accurate at the 1/2 and 1 mile. The 1000m was 147.52mph.
For this morning it predicted:
1/2mi 139.15 -- I ran 139.4
1 mi 161.58 -- I ran 160.9
I suspect the IAT is heating up in the second 1/2 mi which is causing the HP to drop a hair -- which the calculator does not predict.

I was expecting 265-268km/h ( 164-166mph ) , but if you get cooler IAT in the morning hours and tailwind/no wind...sounds like you are there. That's what stock power can give you. I don't belive that the radar was well calibrated for the XKR-S run with 176mph. Stock power is just not enough for that.

not saying it limits top speed but it will impede with every gear shift. the little slip you get is way less than the electronics interfering and dropping your rpm below 2,000. It is time and distance you cannot make up.

It was a hell of a headwind yesterday, some people refused to run because of it.
I saw your RS yesterday, it looks fantastic blacked out! You weren't in the car either time I passed by it. There was a 458 2 rows from you, he waited 7 hours to run and wasn't very happy about it. I don't understand why the long wait between runs, if managed properly they could have gotten 3 times the cars through.?. I wonder what you will run without that headwind today?

The last standing mile event I did was in 2010 in Florida. Same thing almost 4 hours between runs. By 10AM it was 105F on the tarmac. I managed only two runs because when another group came in late around noon they let them jump the line, while people were waiting for 2-3 hours. I left, two runs a total of 7 hours sitting in my car on an airport runway ... stupid.
My best run was 175mph with DSC off but I basically only had two launches to test. The car was AWD and manual so the launch is not easy. First run was 157mph with DSC on, was just not able to put power down.
Now in the old 997 turbo you only had two settings for DSC, either on or off, not three as with the Jags so track DSC might be ok, it is just the drop in rpm that is hard to make up.
