I was trying to ask about your DA (of which altitude is a factor)--my measuring device records it because its impact is significant.

Anyway, on to my point: your numbers aren't great. My last M5 ran 10.33s repeatedly @131mph with a JB4--nothing else. That was on a farm road in WA state with pump gas. The F90 I had prior to that ran mid 10.5s--we eventually concluded that was down to the inferior transmission.

You should be close to or, ideally, better than that with an ECU tune assuming your conditions are similarly optimal... hence my questions.

My current M8 runs high 10.3s/low 10.4s with a JB4 (and an Eventuri intake).
I did that time with no launch control.
In Italy we run 100oct,which gas you run?
Just to compare your 100-200kmh in sec?(60-130mph)

I'll post my numbers below but they don't matter since I'm no anomaly--stock M5s have run in the high 10s in various conditions. Don't take my word for it, though... do your own research.

Errr, wrt/ "didn't use launch control"... why would you do that and then post a less-than-best result? If you're going to post a 1/4 mile time, post your best.

To your questions:

WA state offers 92 octane pump (the mean average of MON+RON is used here). That maps to 96 and-a-bit European octane which I assume is relevant to you so your gas is superior (as is usual with Euro vs US gas ).

The numbers below do NOT include 1ft of rollout because... that's deceitful in my opinion.

My average 1/4 mile was 10.35 at 130 / best was 10.33 at 132.4mph. While I achieved that 10.33 time frequently, it wasn't frequent enough to be considered my 'average'... and I tried many times with that car and ultimately exhausted its launch control count (yes, that's a thing regardless of what anyone tells you, I've hit it frequently).

My average 0-60mph was 2.60s / best was 2.57s.

My average 60ft was 1.57s--this was massively affected (understandably so) by each car's individual transmission.

My average 60-130 was high 6s to low 7s / best was 6.75s.

Take a look at timeslips online... and the Dragy leaderboard for that matter. You should be a lot faster than high 10s.

I'm curious, may I ask what's amazing? If it's the sound you're referring to, then I'm all in--sounds amazing. I have the Eventuri intake, too, and that's just about enough burble, crack, pop and whoosh for me.

My M8 is a Comp GC with a JB4 and I can outrun that time by almost half a second.

HP numbers on a dyno are meaningless most of the time especially without before-and-after comparisons.

Thanks for asking I actually think the car is plenty of fast already. I just got the Akra for the look/sound. Considering Eventuri next, I really love the WHOOOSH sound

Then we're in complete agreement! The whoosh will BLOW your mind. See my YouTube channel (same name) for I think 3 videos of how it sounds—worth every penny. I've no idea why manufacturers would suppress this in the first place. Oh well. Thanks, Imran@Evolve !

Yours average 60-130 was high 6s to low 7s / best was 6.75s.
Mine best was 5.5s and average was 5.7s
The reason why I am faster more than 1 sec is because bigger turbos push more than stock with jb4 whatever map you set.
I am maybe slower 0-62mph with bigger turbo because they need load more air and push delayed compare stock i.e. slightly turbo lag and then jb4 tipically gives more torque lower rpm but med/high is not so consistent.
Mine map is opposite.
This is why after 60mph I start to desappier from your sight .
I am not fan of launch control but I would try it just for you.

You are hitting 1/4 mile like burgertuning jb4 state map5 and race gas 109..
Very very impressive with regular gas you used same time.
JB4 add 80hp and do not compare with ecu map 821hp.

Naaa, I'm not quite there. Terry runs in 10.1s and 10.2s. When in WA, I used a custom map with 92 octane pump gas and relatively cold ambient temps. I've lost a few tenths since moving to FL and have had to lower boost targets as well so I'm probably in the 10.7s now on my M8.

Anyhoo, can you confirm whether your 5.75s time was 100-200 or 60-130? The difference between these two is often overlooked and shouldn't be.

I've had a Dragy since day one—my times are posted on their leaderboard.

The device has earned the credibility it deserves and I, and many others, have tested them against drag strip timing equipment and they're within a few 100ths and close to nailing trap speed hence the leaderboard has allowed folks to compete remotely.

Worth every penny...

Indeed and that is why I bought it. I saw and read lots of positives and it is used by several tuners who could afford more expensive equipment yet swear on its accuracy. Not being expensive and fullfilling all the needs so well, it's absolutely worth it even for those who plan to use it occasionally and for their own purposes without necessarily competing with others. For me it's something new as with all previous cars I never associated any GPS performance measuring device (or APP for that matter) except my TomTom navigation to see the actual top speed I was driving on German highways.

Today I tested with launch control with dragy.
1/4 mile in 10.12s@136.7 mph with 100oct gas while Terry with jb4 reported 10.16s@132.40mph with RACE GAS 109.
This is his best time mine was at first attempt.
With race gas I should be under 10s without dub.
These kind of tests annoying me , are numbers only and every time changing conditions etc..
My next up will be Autotecknic dry carbon seat back cover/Sterckenn front middle carbon splitter and M performance G82 side carbon wings.
Mine M8 CP is black and these wings will fit perfect.

1/4 mile in 10.12s@136.7 mph with 100oct gas while Terry with jb4 reported 10.16s@132.40mph with RACE GAS 109.
This is his best time mine was at first attempt.
With race gas I should be under 10s without dub.
These kind of tests annoying me , are numbers only and every time changing conditions etc..
My next up will be Autotecknic dry carbon seat back cover/Sterckenn front middle carbon splitter and M performance G82 side carbon wings.
Mine M8 CP is black and these wings will fit perfect.
Good numbers!

If they annoy you, then don't buy a Dragy and don't post them. Et voila as they say in a nearby country.

PS: checkout the Dragy leaderboard for some other numbers that will annoy you.
