Very impressive especially at your altitude. My FBO 335i on e30 ran 12.3 best time and the DA was below sea level that night

With a solid custom tune - I could see you doing 1/8 in the high 11's. Congrats.

No tune?

My buddy did a 11.54s 1/4 on winter tires and 41°F on a custom tune.
3.45s to 60.

He has pure turbos now but didn't do any logs yet

Do you have the data graph from that run? kind of looks like you were running uphill. I bet it can do better but still impressive!

A high-flow catted downpipe is the first mod you need to do on these modern BMWs. The stock cats are insanely restrictive. I did it on my M2 with plans to tune but found I was more than happy with the just the DP. I went with FI.

Corrected time

Hi guys I just see all the interest in my build, the car did a pretty good run, the time corrected for the slope was 12.31 and in a perfect DA it will be much faster, as you can see the DA for the run was over 22357 ft no the best conditions, follow my youtube account I will be posting the complete build, tunes reviews in this platform and some sound clips.

No tune, the 60 ft time was 1,86 due to the Xdrive, at sea level the car will be running 11s for sure, my plan is to build the car with forged internals, upgrade turbo and more, soon will be posting a comparison between the m340i and M2C.

The M340i is one impressive machine. Some fast times coming from these cars.

Yeah quick. Not sure why the need for justification. I guess you like more dramatic verbiage that leads to the same meaning :. Quick, fast, movin, runs like a raped ape.

Anything sub 4 second to 60 runs is just amazing and 11 sec 1/4 pass is bad ass. With that being said I'd still take the carrera s, 991.2 or 992.

The next step is to get the tune, and compare it to my 992 s. Will be posting the video of the race in my youtube channel.

No CEL yet, but be aware that emission regulations in my country are really poor so they send us the EU spec car with no OPFs, but not sure if pure EU or US specs will throw Cel.

Fantastic stable you have there. I'd love to see what the 992 can do with a tune. Should be very close to 10's?

Is it a base carrera? I want to get a base and do sport cats and tune. I talked to fabspeed and Cobb they said the only difference was turbo size and tune the internals are all the same

It is the carrera S versión. I think the sound isn´t that great with dp it will be worst, it sounds raspy in person and I got the sport exhaust package, do you want to see a cold start video of it? In comparison the M340i sounds much better so if you want a car to tune I wouldn´t recommend the 992 as option.
