Eurocharged Tune for M5

What about G-POWER?
They claim more than 100hp for the f10 m5

Its a version of the development file as well coupled with a mechanical boost controller. No doubt it delivers though, just don't approve of the shortcut. There are obvious consistency issues with the Manhart setup, and this is identical.

Which inconsistency issues with MHR are you referring to?

I believe they use the MHR setupp with a slightly modified "press tune" and a boost controller. MHR has had 700-750Hp M5/M6 for over a year now.

Thing is, it's not yet possible to get the desired power just by software remap. They all need some sort of additional boost controller.

And what are we afraid of boost controllers?
Sorry my ignorance

Because you'd rather want to be able to write a boost map on the ECU software so you can map and adjust every parametre and retain safety features.

The boost controller is a way of "cheating" or tricking the ECU into believeing the boost is at normal levels so that it won't shut down the engine with the increased boost levels the engine actually has.

And how much longer for this to happen?

Because everyone here will have it

Thank you for the explanation.

There seems to be a great variation in its performance , looking at vids of it running other cars .that and them only doing limited runs at airfield events.
From people at the events , they have had DCT overheating issues . I fully believe they make good power , just that there are issues with 600 WTq in regards to the DCT. They also are very selective in who they run at events . Manhart is a very solid company ,I'm just a sceptic by nature .

First of all, they are the only ones with a M5/M6 tune that I have seen that has supplied their cars at events like GT Board. Strange that this should be used against them. What events/competitions are other tuners doing that is better?

And, I have not seen/noticed any "great variation" in performance looking at the videos. Which videos in particular are you referring to?

In fact, it seems to have a consistent performance from the vids I have seen. It has been put up against a wide variety of competition, like RS6, 458, 430, McLaren F1 etc. Obviously the MHR car will compare differently with different cars...

I agree, manhart's tune had been proven over and over again. I don't question it. So many races and vids to back it up. I would do it but shipping my ecu's overseas is my only problem.

All the vids are official Manhart adverts . I would much rather have an end user video . I've just seen to much over the years. Manhart is a great company , and certainly have made the most out of the development file. I put much more stock in an end users trap at the strip or 60-130 times than videos .Way to easy for vids to be misleading, other car in wrong gear , unknown mods etc.
My two cents

So now it's "All the videos are official Manhart adverts" and not "great variation" in performance anymore

Which is it? Do the videos show a great variation in performance or are they all official MHR adverts? If it's the latter, then why are the films and events created, edited and published by GT Board etc. and NOT MHR? If it's the first, then it seems strange that Manhart should have official adverts showing a great variation in performance...

And, which videos are you referring to?

The GT Board videos are NOT Manhart Racing official adverts. GT Board is run by a Swedish guy and he has arranged drag strip events for years, inviting cars from all over Europe to his shootouts. What we see are real races by invited people. Gustav from GT Board publishes the vids.

And, as you can see on GT Board vids. They often do multiple runs to make sure both cars do the best runs possible.

There is also a MHR M5 in the GT Board videos that is a customer car, driven by the owner who also happens to be a member on this forum. He has also posted his own times achieved in his own car by himself. His car was actually even faster/quicker than the official MHR times...

You say that you value much more highly trap speed at the 1/4 mile, but that depends a lot on track conditions, temperature, humidity, altitude etc. And not to mention 60-130 times. How do we know the time was not set going downhill... Yes, all things being equal. Trap speed and 60-130 times say a lot. But to give any valid comparison, then the times need to be set on the same day at the same piece of tarmac, driving the same direction... The beauty of the shootouts at the GT Board events are that all cars have the same conditions to compete under and what you see is what you get. No excuses. If you missed a shift, then they do a rerun.

It seems to boil down to your "feelings" rather than fact when you claimed "great variation" in times and inconsistent numbers for the MHR.

Can you please provide the videos you referred to that showed "great variation" in performance?

Here is a video of the customers M5 vs a C63 AMG with 520hp

[pablocr]

I can say that I am dissappointed, 2 months ago I decided to trade my c63 for a 2014 m5 or 2014 e63 I think I chose wrong.
Renntech is making 686 hp just with tune out of the amg 5.5 litre biturbo

We are getting off topic fast here . One example then I'm done . The MHR M6 comes from behind to beat a 911 turbo PDK , yet beats a 458 Italia which has a even better power to weight ratio and a fantastic NA motor , from the start ? That doesn't make sense logically . Don't know why you are getting so upset ? End of discussion .

I'm not upset, but you have made so many strange statements that doesn't add up... Like the videos being official MHR adverts, which simply isn't true

I just asked you to back up all of your claims. If you make claims about something, you should be prepared to back it up... If someone asking for verification of your statements is deemed being upset, then what is the point of discussion forums? Should we just all accept your statements about MHR as being true

I'll post the videos you refer to and let people decide for themselves if there is any "great variation" in performance:

And Porsche 911 Turbo S vs 458 Italia:

Based on the above videos, where the 911 generally beats the 458 Italia, it isn't surprising that the MHR M6 has an easier time with the 458 than it has with the 911. There is no "great variation" in the MHR M6's performance in the above videos as far as I can see. But maybe other members think differently? (I'm sure that at least gmd2003 is convinced that the above videos just confirm the great variation )




And for reference regarding acceleration properties of 458 and 911 vs McLaren MP 4-12C (once again the 911 seems to be closer at the start than the 458):

[Boss330]

Oh, and this drag race between a 911 Turbo S and a 458 Italia also seems to "indicate" that the 911 is faster than the 458. Again putting a perspective on the MHR M6 vs 911 vs 458 races:

[cpiguy]

Base on my personal experience this last video seems off. Not sure why. Just as a reference, I've raced a couple of 911 Turbo S's from a 40MPH roll and we were preety even to 160mph. I also run down my buddies 911 Turbo non S by 5 to 6 car lengths.

From a roll a 997 turbo is not faster than a 458 . The 458 is lighter , has more horsepower , and better gearing . Agree that a 911 turbo does launch better and wins from a dig . 458 'do trap 130mph stock in the quarter mile , which is much more than a 997 911 turbo . So while a 911 turbo might be quicker off the line a 458 Italia is the faster car from a roll . Thus my comparisons are not strange at all since almost all of these vids with the MHR M6 are rolling races . I am using nothing but facts and logic . I think I'll just respectfully disagree with you at this point . I'm done arguing .

No problem disagreeing on this Nothing personal.

Just want to point out that these two videos, shot on the same day as the MHR M6 races, prove that the 911 can be faster also from a rolling start.

These are the facts and logic I choose to use; Runs with rolling starts, done on the same airfield, on the same day, under same conditions. These races clearly show the 911 pulling away, from a rolling start. To me that clearly explains why the MHR M6 struggles more with the 911 than it does with the 458. The 458 looses to the 911 on this day and this event. So, obviously a run under the same conditions will show that the MHR M6 will have a harder time against the 911...

My point is I can make a video look any way I want , you can't change the trap speed at the strip . I don't trust these vids as authoritative , people can be in the wrong gear, have undisclosed mods , sandbag intentionally , etc . I can show you dozens of vids of Sasquatch will you believe that too
