Went to Kempower yesterday, results of the new dyno:
205.0HP -> 206.7HP
435.2NM -> 436.8NM

Guess there's little to no difference. He told me my emissions were cleaner, but that's very subjective of course. Think I don't need to change my diesel, maybe add a little additive every now and then to help keep the injectors clean

A friend of mine also had his 320D done : 206HP and 444NM!

Wow 444Nm!
Was that at Kempower as well?

[etik]

I wonder if I should go to kempower to get another dyno. to confirm my numbers.
I see nobody above 440/444nm ??? I guess my dyno is wrong ???
Do you know how much they charge for dyno ? I'll call them anyway.

Hi Mantis, how is it to shift all that torque with a manual stick? Smooth or not smooth? Any differences?

530d with 500nm is perfectly smooth ... why would this be different?

Yep! And it's only 2% better, that's what I keep telling myself, haha :rocks:

Absolutely no problem shifting, it's just as smooth as before

There are other people who've had 450+ NM
Just look at http://www.kempower.be -> Hot news -> specific car news
But the max torque doesn't tell you the whole story.
You have a strange drop in power around 3800RPM, is that noticable when you drive it?

Don't know about the e60, but my old e39 530d MT was a pig to shift with only 400Nm.

That wasn´t with a manual stick was it?
I just wondered if it would somehow loose its "smoothness" with over 100Nm more than it was designed for. I´m just very curious because I want to remap my car as well. Seems like a lot of fun

Maybe this is a lot to ask...but are there any of the belgian guys with a kempower remapped 320d who are willing to let me drive their car 4 a few km?? I really want to know what it feels like before i pay 750€.
Thx,

Believe me, it's worth it. Compared to the ridiculous prices of some of the factory options, a remap is a bargain. Basically, you'll get a 330d for the price of a 320d, just as I got a 335d for the price of a 330d. And you get better fuel mileage! Life isn't usually this generous to us, but here it really is a win-win situation

My 530d was an auto, but the manuals are fine.

The 330d also has 500nm and plenty of people are happy with manual boxes in those.

The only problem is that you can't dms the manual 530d / 33d because you'll melt the gears.

What do you mean by "dms"

But it´s not the same box as is in the 320d?

Here´s the 320d manual box:
(There are two versions, a 340Nm and a 370Nm. The first must be for the 320d 163hp and 340Nm (same gear ratios), while the latter maybe is for the latest 2 liter diesel with 177hp and 350Nm. I´m not sure though.)

It tells you the max input torque, which to my understanding is a lot different than the output torque that is measured at the wheels. See that you have the difference in RPM of the engine and the wheels and the gear-ratios and all that
I wish somebody could explain how that works exactly though, only so much you can pick up from howstuffworks.com

Oh shit! I thought I had it there for a minute, but now I´m even more confused

I was wondering the same, but maybe he means a remap done by DMS Automotive? They take the 320d to 208bhp and 406Nm.

The figures quoted by BMW are for engine torque, which is measured with all accessories (e.g fuel pump) connected. Torque at the wheels will obviously be different in every gear.

I really don't know if the 330d and the 320d have different gearboxes. But what I do know is that a 330d with 500nm of torque shifts prefectly well.

If your chosen remapper (and I was referring to DMS in my post) are happy to tweak a manual 320d then it is probably because they are satisfied that the gearbox CAN take the extra torque.

I know that DMS will not remap a manual 330d for the same reason.

[AK]

But why does DMS only take it to 406Nm while Kempower takes it to 440Nm?
Could it be that DMS knows something that Kempower doesn´t?

[Mantis64]

I think the clutch would be the first to go if the car can't handle all the increased torque. I mean the gearbox doesn't shift to another gear while it's spinning, right. It's the clutch that has to do the hard work: getting the engine linked to the gearbox after you changed gears.

At my dealers they converted a 120D to a race-machine with 250HP!!!
I should ask them how they manage the extra strain on the drivetrain
