Thats a whole lot of power & torque :joy:

Pity about the weight it slogs around :nonono:

 

[Raybimmer]

Wheel kilowatts seems down , maybe a lot of transmision losses .
If a car makes 400Kw at the flywheel then 340 Kw at the wheels is a 15 percent loss , i.e. 60 Kw not being used to move the car . The torque is good , this will help accelleration .

Cant wait till one of these engines end up in an E30.

Car magazine tested it down here in Durban at Autotrix Dyno and it made 345wkw/611N.m, making it 16.26% drivetrain loss. But in comparision to the CLS 63 that they also put on the dyno only showed a drivetrain loss of 9.59%, as it put out 349wkw/689N.m.

Now is this dyno not up to scratch or manufactures are claiming lower power outputs(which i don't believe they'll do)?

By the way the 1M only has 4% drivetrain loss and produced 240wkw /513N.m(Overboost). However they did say that this particular car was not an over-acheiver as another 1M also pushed similar figures a few weeks back.

I use that dyno all the time it is accurate on wheel readings
I was also there when they dynoed the other 1m.
Stock c63 makes 238kw on that dyno , stock v8 m makes a little less than that .
So the figures are right on the m5.

So the 1M should be faster based on power and weight?

Wonder what wkw C63 is pushing at coast

 

[anile8-zn]

This dyno is at the coast

This dyno is at the coast

oh ok, just seems that the C63 puts down so much more power than that on the road.

 

[anile8-zn]

Stock 63 is not very quick , the tuned ones make 350wkw at autotrix though

 

[Twinz]

Its a pity that we have to compare the C63 with the new M5...:nonono:

Our older boeta M3 is not even in this equation...eish.

 

[Seether]

So in theory, a stock 1M which puts out 240wkw in stock should be able to keep up with or even beat a C63 AMG stock on the coast.

I bet this is not the case. In my opinion, the C63 will take it fairly convincingly.

 

[anile8-zn]

I would wager a stock 1m will be ahead at the coast !
It's basically a boosted 135i !

At the coast you need a 335 that is tuned at 14.5psi, DPs, at least 98 octane and a decent driver to take down a stock C63.

With full bolt-ons, meth and JB4...well ya they will say you on Nitrous.

But you put a tune and Exhaust on a C63 and the 335 will need to run at 18psi or more to keep up with the C63...

The C63 just begs to be raced with and raced against...it is formidable :thumbs:

I saw chiplogic tuned three C63s in Cape Town when they first came out and man those machines transformed overnight:thumbs:

Those C63s, especially at the coast are absolute monsters.

 

[P Smit]

You guys refer to kw on the wheels, produced at the coastwith very small % transmission losses. Are you referring to kw measured under load or as inertia runs? I cannot think that a 1M will make 240kw under load even at the coast, measured at the wheels

 

[Twinz]

@Smit...in the WC you wont be puzzled, here we measure at the flywheel like all car manufacturers do...the rest of South Africa is out to confuse you. :rollsmile:

Hi there, I have logged & dyno'd 2 M5's up at altitude now. I can confirm that BMW has some form of altitude compensation built into the boost logic. Whether it's deliberate or accidental I don' know but it massively overcompensates at altitude. The wastegates are fullyclosed from 4500rpm at altitude. There will be zero gains chipping the M5 up here. The good news for sea-level cars is that there is headroom for boost increase at sea-level. so you can gop from 350 to 400kw on wheels with software once it's cracked. But altitude runners, unfortunately you have to stick with hardware mods.
