No big tracking problems but when the car got to 3rd gear it feel like it MDM would kick in but the light never come on , on the dash. Then on 5th gear it would just die at about 155mph..and I would still have at least 250 meter or so to end of the 1/2 mile.. best..so most of my runs were 153 mph.
I did put a diff methanol .. hot shot by power mist and It does have additive that I was told made the JB4 go into safe mode and cut power..
I empty the tank and added M1 by VP and after a few more runs and some rest did get a 16mph but still you could feel the car just cut power in middle of the gear and pick it up and the end of the gear. So I thick clutch can't handle the torque of the car..
A few thing If I ran the car with DSM off completely the car died at the 155 mph
I mean It would just quit on me !!!. So the 160 were on MDM.
2 other M5 with JB4 on map 7 with 104 did 161mph...

and I did talked to my tuner and He did send the log of the Dyno to Terry last week and I think he told me that he share some info with George ..
I guess next step is better clutch..

Looks like a fun event. 160-161 seems about right for the M5 FBO on the BCM.
It took a loong time and many experiments to dial this setup in without DTML or misfires.

Keep pushing it and traps will keep creeping up!

Most important is to be safe...!!

Bc good traction or no that will be telling .FYI an M5 at ATCO with just BMS at 3.5 psi and exhaust and race gas, no meth , no NOS ran a 10.9@ 131 mph and had a highest trap of 133 mph with DR's .

Honestly 130+ without the BCM is very hard to believe. Let's see what happens at Famoso.

Did you have drag radials?
Also it seems to me your topend limiter is kicking in.

My M6 with drag radials with full bolt on JB4 and meth/93 octane ran 157 and best 158 before the 1/2 mile. The extra mph was to the larger diameter of the drag radials. Same feeling once it hit above 155 power would die also looking at your Dyno sheets it seems power drops at the limiter ask your tuner if the limiter is still there has to be,

Either way don't get frustrated, when running meth and more boost car has to adapt consistently before going to the track. Same fuel same %meth and boost. Too many changes the car will not be consistent.

So I recommend you find out if limiter is still there which is pretty easy go on the Dyno in 5th gear and see what it hits. If it stops at 6200 rpm your limiter is still there
Use 100% meth at all times if you want the most power out if it.
What are your tune AFs Peak? Mid 12's? Or high 11's?
The richer the mixture you want less octane for example use 100 octane instead of 109. 109 if your AFs are Leaner mixtures other wise it won't run as good. Will take some daily testing.
Also go through the adaptation method for at least two weeks after your install this way the car has adapted fully to your mods and boost. Keep boost and fuel consistent.

When I ran world record 10.7 @ 129 mph all I did was adapt the car for two weeks. Just ran it every night a couple times through the gears and parked.

This way the car learned to drive at its peak with the same fuel. As you can see I had consistent passes in the 10's and the car kept getting even faster that day at the track.

I recommend drag radials otherwise your wasting your time as well as running in manual mode not auto. Mdm will only hurt you everything needs to be off and suspension in comfort that is if you're launching the car.

Also drag radials need high mph to get hot enough. Best way is to go in water start in first and once starts to spin go into 2nd and into 3rd, the car will spin up high mph and as the tires start to heat up and stick let off. You don't want the clutches to heat up.

Now you're ready for a great launch.
This was the process in my M6 which my 60fts were 1.72-1.8 and best 1.67

Good luck and once again congrats on the nice gains

ATCO is a fast track but it 100% is legit . My point is the much lower power cars on DR's from 2014 are running the same ET and traps as the high dyno cars so far and no one has beaten George's 10.7 ET on either the m5 or 6 platform no matter what dyno gains they show .

There are few m5/m6 trappig over 130 without a BCM

I think you guys may be interested to watch this video especially at 11:24
I have no clue but 800 HP,1000 NM (~740 lb-ft) Evotech M6 is claimed
1/4 mile: 11.3 second @ 126 mph
1 mile : 20.4 second @ 164 mph

I hit 168 in the 1/2 mile so something is wrong with that car to hit 164 in a whole mile!

I don't doubt 10s is possible with good traction even with 650whp. 133mph is hard to believe unless north of 720whp

Yeah but clearly their car can catch those numbers...

well maybe different condition including altitude, weather, track, etc

[Msizzle]

Drm5 it sounds like you are definitely hitting the limiter, but respectfully how do you not know if you have a limiter or not? Also on our cars at these boost levels there is no value in going over 100 octane, most of the higher octanes are leaded. These are all things that should have been discussed with your tuner. The octane is to prevent detonation, you can run more boost and more aggressive timing, once those 2 things are maximized for your setup on said octane, fuel octane is no longer the limiting factor. So translation 100 octane is plenty for pretty much any setup for our cars right now.

This car clearly isn't making that much power, trap speeds tell the story. If a stock car has around 520whp this car has 600whp or so.

Do you know the owner? Just curious because so many cars claiming all kinds of power are trapping 128ish, I think a bms stage 1 can get to that mph but you would need to be on +5 or 6 with race fuel. It also doesn't require race fuel until +5 so are you sure he wasn't running more boost?

The mentioned car belonged to a customer of mine. It also had meth and catless downpipes.

You can get a lot more tire under these other cars. At 650+whp need an 18" rim and a true slick. Not going to hook 800 hp on a shitty drag radial.

Well maybe this video was not a good example. My point was the effect of tuning over the stock. The video shows (at 11:24) the tune car has 9 mph higher trap speed compare to stock (117 mph for stock) while we know the stock M6 has 123-124 mph trap. Having said that, about 9 mph over the stock means 132-133 mph trap for a car with almost 200 HP more than stock. BTW all of their (Russian) trap speed are a lot less than the real world if you watch their other videos (ie F12, RS7, M4, C63, Huracan, etc) here:

I think a customer or 2 from PR has used this Dyno. Reads a smidge high for sure if it's the same one, their FBO
M52 e30 was running 15whp more than the norm.

Exactly!

Except me who just ran a 9.4 at 155.6 on a street radial NT05R in the rear and nt555R in the front 23lbs of boost

They are 18s tho lol But they're my rain and snow tires lol

C'mon that's a GTR... you can't compare an apple to an orange! That car can do 2.8s 0-60 bone stock everything. Make comparisons to things relevent and that's an //M car.
That's like John Force coming in here and saying we all suck cuz he can do a 3.x @ 330!

lol my 1/8th translated to 0-60 is like 1.5 I mean the car was still full weight everything so 4000lbs with driver
