This is the ONLY review in the world that says 545i makes 6.5s on the 0-100, ROTFL: do you want a video attached to this reply ?
That magazines clearly got money from BMW to publicize the new diesel .

The difference beetwen reality and that review is that 535d makes for sure 6.5s, 545i instead 5.5 the manual and 5.1 the steptronic .

This is 5.5s by Andy, but if you start to accelerate with the left foot on the brakes and in the meantime with the right foot accelerate ... They become 5.1s .

545i 6.5s ?
Lol, you are mad .
535d instead is at 6.5s .
In next days I will register a clip for you of 5.5s or similar
Obviously, you will register a clip for me of your 535d that makes 5.0s, right ?

Coming back to real world, remapped 535d makes 20s . 545i and 550i makes better . Thus the 535d doesn't have neither 360 and 400 HP .

 

I wrote all that stuff in vane. I didn't say i agree with that mag. Again you understood what you wanted not what i ment.

You do that. Give me a 5.5 with the g-meter reading and with the road, and after the remap i'll give oyu smth close. And you know...drag is not all about 0-100km/h. Oh no! I am perfectly aware that the petrol in general has an electric response and hence i'll always be handicaped on that even with the remap, but watch out after 100km/h .

I also hardly wait to get to Germany. Dyno test in ins tock, remap, and dyno test it again, AND after that run with a 545i, tape it, and upload it here. And we're done once and for all.

 

Anyone thought about the fact that the 535d uses twin sequential turbos? The second turbo is already pretty big - I suspect it'll take a lot of engineering/testing to do turbo swaps on this motor, given you'd need to keep the right "balance" between the turbos.

Still, if you have the budget...

And for xBMWx, Alpina isn't really a tuner as such, plus they haven't made a Diesel 5er since the E39 D10 Bi-Turbo (as the name suggests, the first twin-turbo BMW diesel), whose injector technology was then used in the next generation 530d.

 

Yep! I did: http://forums.e60.net/index.php?s=&sho...st&p=440416

 

Better, I don't have whim to quarrel: I know the 535d is fast and the remapped 535d even faster . But you can't remap it to 400 HP or 360 .

If you disagree, post a 0-200 clip of 18s for 360 HP or 17s for 400 HP: the fastest 535d I have seen till now needs 19.5s to reach 200 kmh (about 206-207 kmh on the speedometer for real 200 speed)

If you aren't convinced yet, we can ask to make a clip to a member that owns the 550i step .
But is simpler: you have a remapped 535d ? Ok, make a clip so we can see the result .

I use to say that if a thing is round you can't say it is square

 

We can suppose a 535d could have 400 HP . Ok . And reability ?
I like my car, I would like to continue to have it functional .


I know a man who assert his 535d has 350 HP ... But he makes 20s on the 0-200 . And stock Andy's 545i (333 HP) 19s .
With the extenuating circumstance that the 535d has even shorter gears than step 545i .




Excuse me, but if you make this sort of mod ... Look to Racing Dynamics site and check how many mods you could do to 545i/550i
With the difference that 545i/550i remains reliable .

 

I wonder, if you tuned a 535d to 400+PS, whether its fuel economy would actually be better or worse than an Alpina B5, which gets by with about 520-530PS? Certainly, you could push the purchase/mods cost up towards the same level.

535d's a great car (I nearly bought one of the first, but cancelled the order and got the Alpina instead) and of course tuning is fun, but there comes a point where some projects just cease to make much sense.

 

From previous experience with changing out turbos in petrol cars Id say unless you go to silly undriveable levels fuel consumption doesnt change much. Im not talking about major internal mods here but simple hardware changes that is run of the mill with normal turbo performance tuning so shouldnt cost the earth.

A new bigger "big" turbo/downpipe and intercooler should only be around ?2k plus fitting with a custom remap on top. Im thinking around ?4k all in maybe, so not a huge cost if the gains stack up. In a petrol car, if done correctly, this set up will give 50+HP over a standard remapped car depending on turbo choice and I dont see why the same would not be true for a diesel.

Any transitional balancing issues of the sequential turbo set up should be able to be ironed out in the mapping process providing both turbos are compatible.

As far as I can see no-one has actually modded or even attempted to mod a 535d via harware changes other than exhausts yet so its early days, however given the number of remapped 535d's already around, its only a matter of time before someone like me gives it a go!

 

Yup, although doesn't the "balance" of the two turbos work mechanically on the 535d? i.e. the small turbo stays in until the big one has built up a specified amount of pressure? Might require some manual fiddling, as well as in the map. Not beyond the wit of man, but could take some time to perfect. With the bigger charger, it might make sense to uprate the injectors, for example, but how does that work on these newfangled common rail direct injection thingies?

How big is the intercooler on the 535d? Is it fitted in front of the rad, as on my car?

 

It's impossible to give 400 HP to the 535d . Or, if possible, it will explode after 10 minutes :-)
