For both

[A_]

Times for m5 cs at +21 degrees Celsius
0-100 2.98
100-200 6.69
1/4 - 10.64

and 1/4 for m5 g90 - 11.32

couple dragy times

In 1/4 mile trap speed what counts given 0 to 60 can be affected by a lpt of things

Why ? most of us have dragys

With a stock tune Ambient Temp. doesn't make so much difference below 30C because stock tune is setup to increase boost with higher ambient temp/IAT to compensate for less oxygen.

They made these low 6s at around 20 degrees Celsius. And that means they will make high 5s under ideal conditions and low temperatures.

Look here - 6.69s 100-200 in M5 CS F90 at 18.5 degrees celcius on the summer. At a lower temperature and better conditions you will do 6.40-6.49

I am not talking about a big difference. If it does low 6s ( for example 6.2) above +20 degrees Celsius it means that at +5+8 degrees Celsius it is certain to do for example 5.9s. I used to have 2x m6 f13 without box and with box. If at +23 I made 6.6s then at +5 degrees I had 6.1-6.3s

[IMS-340C]

You know what really makes a big difference but no one is reporting, wind speed and direction.

At 100-200 the wind and direction does not matter so much, but nobody in Poland measures cars in bad weather because it is dangerous. Only when you measure 250-300 does the wind direction matter

They produce consistent professional results and have decades of experience. Let alone when setting lap times use pro drivers that are consistent across the board using different cars.

This is the data and information i want to see.

Yes you are right but this thread is about straight line acceleration as most of us don't have track access or don't want to track our cars.

They also provide straight line data in the written write up.

Nothing wrong with draggy times, but i consider the top tier magazines as reliable, with any variables or concerns often noted.

[IMS-340C]

0-100 km/h is not affected that much but a 20 km/h head or tail wind considerably affect 100-200 km/h.

Well you are right.
Car is travering about 250m going from 100 km/h to 200 km/h in like 6 seconds(if we consider constant acceleration).
20 km/h wind in 6 seconds will affect about 33 meters which is not negligible.

[A_]

At 100-200 the wind can increase the time by 0.1-0.3s but if you measure 250-300 then it can be as much as 1.0-2.0s slower. But as I said before, if someone wants to measure a car then choose good weather with no wind

Will do few runs 100 to 200 stock with bmc filter this week before break in service
Then few runs with jb4 after break in service
Then few after catless sec downpipes

Here you go!
Went outside for 2 runs
Car has 335 miles lol buy i have to do it
On 93 and NOT ON E20 MIX LIKE THE M8
Stock with bmc filters only
Same spot where i tested my m8 coupe

10.9 w a tune lol?

this thing cannot launch

That's a decent 100-200, thanks man enjoy it

It's a very mild tune, this thing with a stage 2 tune will be very fast.
