Hi, this is my bmw m2 , dct.Only a sport cat 200 cell is installed. Outside temperature +11.Ukrainian shit fuel 98. No bad, for stock m2 with only sport cat)). I believe when there is good fuel, she will go 9.5)))

Thanks for posting that. Did you do a 100-200 test before the installation of the 200 cell, too?

Yes I do, best time was 10,8 on the same fuel,on the same road.My brother bmw m5 f10 did 100-200 8.0-8,2 s, also on this road and on the same fuel.

1.1 seconds, not too bad

That is 13.9s for 0-200 km/h comming from 15.0s or 14.9s comming from 16.0s depending the review you rely on

[SliChillax]

That's the same time as my M235i with JB4 on Map 2, shit 98 fuel and armytrix catless downpipe.

That's a pretty good pickup over stock with just the sport cat

Did you correct for gradient?

[Leonidm2]

Today I again do races and I got the same results 9.7, but what I noticed, I did 4-5 runs without stopping and the results were the same, it's interesting, stock intercooler work???

Problem with vbox times like that is they don't correct for road slope. A relatively tiny grade has a large effect on results.

9.7 stock is very wrong. From extensive tests on several m2s we tested last winter;
1) stock: 10.5-11.0
2) IC only: 10.5-11.0
3) Catted Downpipe only: 10.2-10.5
4) +4 psi tune (jb4 map1, jb+, Dinan sport tuner): 9.7-10.0
5) +4 psi + IC: 9.4 - 9.7
6) +4 psi + DP + IC: 8.9 - 9.2
7) dp + ic + flash: yet to test

All use 98RON.

Your PeakG is 0.9G, are you really believing in that? From 100-200? It'd be even impossible to get 0.9G stock from 0-100!
There is something very wrong with your box DEFINITELY.

100-200 is in KMH, not MPH

Did my numbers look in mph to you, Seriously?

J/K.

But what could possibly be wrong with his car/the vbox when the OPs car is 0.5s faster than your cars, it's not a very big difference....

On a German forum was a guy with a 6MT 0-200 in 14.5s stock(according to that V Box)

Point is: What's the truth? The slower times or the faster times?

I think 'we' are always more suspicious about faster times, while also slower times can also be 'wrong' (driver/atmosphere/circumstances etc) just like faster times.

Peak G is the hint. A dp car can barely reach 0.5g from 100-200 but he made it to 0.9...

BTW, my numbers come from many enough testing on several m2s, and we are still testing different setups. We believe in high level of confidence our results reflect the truth.

[SeanWRT]

This is the best result we had among 50 or so slips we got with several m2s with dp on stock tune.

Understand this, so we measure all our cars only in one area in one place road.

And where does that 0.9G come from if 0.5G is average accelleration of a stock M2?
Just asking...

Maybe it's because I'm accelerating from 1 gear to the end.The best time I had was when I was accelerating from the site. I reviewed other photos and there are 100-200 -10s and there really is 0.4G.But I did new measurements and really had 9.7, but did not save the photo, especially for SeanWRT I will make new photos soon)).

[Leonidm2]

....and not stock ,as you could see up I wrote that I have a 200 cell sportcat

[Yellowflash21]

Here you go, from this German youtube channel, they mounted IC and 200 cell downpipe with 2 people in the car, around 9.6 sec.

With DTE piggy back mounted 8.4 sec.

This one is with Manual transmission.

Well, that's what I mean, 1 person is somewhere 0.2 s from 100-200, that is, where it's 9.4 thanks for the video.
