PP-Performance 800bhp top speed (video)

As I promised I shot a video of the car accelerating to its top speed. It seems that at exactly 328 km/h or 316 km/h on v-box there is yet another limiter. My car reaches that speed so fast and then it gets stuck. We will now look into removing that limiter as well. It seems there is a limiter on the gearbox.

Unbelievable how smoothly the car is riding at that speed.

I wonder if the 6MT has a limiter in the trans?

Awesome.

It's probably the exact same limiter in the DCT as AC Schnitzer discovered at Nardo on their M6 GC. I believe they found it cut in at 320km/h (as per Nardo speed trap measurement).

Thanks for your efforts at testing the limits of this car. I wonder why BMW has felt it necessary to have redundant limiters? Would they even answer the question if it were put to them? I speculate that they have built an engine that will be their base power plant for a number of years, and merely through programming changes will be able to match the competition if the horsepower continues to escalate. It seems they don't want their customers to be able to reach the full potential of what this car is able to deliver, and wish to reserve that achievement for the factory.

I would guess that the DCT or parts of the drivetrain, which the second limiter is supposedly related to, are not rated for speeds (RPMs encountered)over 190 or whatever the second limiter is set. It would suck to have a drive shaft, joint, clutch, flywheel or whatever reach it's limit and give up at 200mph.

the old post reached 3 pages and people asked for video, after you posted it, the people against PP-Performance didn't show up.

I think they are shocked and had heart attack hahaha

Awesome progress!!! But 800hp? That seems a tad ambitious.

As Boss330 stated, it is the DCT Speed Limiter that is restricting the true top speed. And yes, it appears that BMW M is now trying to protect what the drivetrain and engine are truly capable of, power and speed wise. Additionally, it has been rumored, although not confirmed, but about 90% sure, that the next generation X5M and X6M are going to get reworked and uprated versions of the S63tu engine that will be rated at 600hp from the factory. We have even already seen BMW officially announce a 600hp F10 M5 with the 30th Year Addition M5 also. All of this means that the S63tu powerplant is a vastly more capable engine and BMW wants to protect that or it may hurt their products in the future that use the same hardware. If you even just look at the old N54 twin turbo engines of yesteryear, some tuners were able to extract 700-800hp or more from those little 3.0L inline 6 engines, but with heavy reworked internals I'm sure, even still, it just goes to show the true potential of turbo engines. So who knows what the S64tu powerplant is really capable of??? Maybe it can make over 1,000hp reliably with a proper tune, but I have a feeling that we will never ever know, because these new systems are so well protected. I have a feeling that the next generation G80 M5 will also get another reworked and uprated version of the S63tu engine but probably combined with hybrid assist, and thus making it much faster than todays F10 M5, but I'm honestly starting to get tired of all of the dead ends we are running into with this new technology. Might be looking for a car with a nice old fashioned Naturally Aspirated engine for my next car. Lamborghini Huracan anyone?

The green machine bro. Can't get more naturally aspirated than that. Nothing beats peddle power!

DINAN and second tuner I don't remember off hand (think it was a german tuner) independently indicated that the stock rods are good to about 650hp.

I would've thought more as well… time will tell.

Car was tested on a Maha with 791 bhp at the crank. Since then I deleted the cats and installed a full IPE exhaust. I am over 800 bhp.

How are we doing with the TRACTION -
I can't imagine dude!
You need to change rear tires every week this way -
Not just that I am not sure how much impact on 0-60 and Quarter mile trap time , for sure they will be better but number won't be worthy of 800 crank HP!!

Like if it were AWD every single pony will score but this way you are getting at Max half what you deserve because of traction!! More fun though -

Have track numbers or not yet?

Great Job Man!!!

I'm planning a 1/2 mile drag race in September and need my Top end limiter removed. How can I get this done here in the states.
Also don't want to effect my BMS stage 1 with meth, do they do just the limiter?
Let me know
