Just seen this pop up on Youtube by a chap in Germany with a 340i X-drive.

My German is sufficient to understand the following:
- Same car (1st test at 21k km, 2nd once he'd had MPPSK installed at 28k km).
- Same road.
- Similar temperature (within 1.5C of each other).
- Same camera.
- Both times full of fuel and just the driver.
- However the MPPSK video was filmed in heavy rain (non-MPPSK run was dry).

Result is this:
100-200km/h - MPPSK is 1 second quicker.
100-250km/h - MPPSK is 4 seconds quicker.

Only 1 second quicker to 125mph is not very impressive, at least the conversion sounds better. I wonder what the 0 to 70 is?

[james d]

Not quite as it's from 62mph-124(5)mph,sure 0-125 would be at least double that but most improvement seems to be above 125mph which I'd never get to so down to, is it worth £2k for the noise?- Maybe!

Not sure about the mppk but I can guarantee that having a tuning box on a 340 makes for a much quicker car. Wet weather would make a bit of a difference I guess.

Nice comparison of a 340 vs 335d test below from the same page. Just shows what we already know...

That's a very flawed 'test'. The 335d is a heavier touring and not even run in yet, whereas the 340i is a well used lighter saloon.

Yep - coupled with a dry road for the 35d and a wet road for the 40i......

Oh yes!

I would have paid £2k for the exhaust alone. The added power is a nice-to-have

I think not. The launch video was on a wet road, but you don't think he accelerated all the way to 155mph on that wet narrow country road do you? More likely the acceleration all the way from 0 to flat out was done on the autobahn where the road is clearly dry.

My mistake I saw it as 0 to 250 kph

Fair point but non of it is consistent and you "assume" that the full speed runs were done on the autobahn (fair logic) but the big-d never reached max speed before he backs out due to traffic on the vid showing the road conditions.

We can therefore just conclude that whilst the test is non scientific, the 40i sounds great

and is quicker...

[73henny]

The noise - agreed!
Faster - no chance. Both limited to 155 and even if the 340i gets there quicker it'll have to stop after a few miles for fuel

Thanks for this.

He also states that the road was pretty much level.

Good to see the use of the indicator as he overtakes traffic!

We did this the other week.

Quite a difference at 100mph

Aw cmon its been a month since that thread, surely time again to bait some tractor owners...

[QUOTE=Grant_7;21414321]Oh yes!

I popped a post up a few weeks ago of 2 340s racing on the Uk roads 1 was Stock other MPPSK, the MPPSK one left the other by quite a margin, considering its only 36bhp gains it looked quite large, unfortunately that video was taken down.

Noise wise no brainer the cars so much fun in sport, wind ya windows down and it makes people jump if you time it right...some want that

However some don't, I needed that 360bhp as I came from a 420bhp car, and for some reason the internal dials register 385bhp, unsure how accurate they are.

also you don't want to had by Golf drivers do you ? MPPSK will put some distance between you

Funny you should say about the dials as mine (non MPPSK) shows 340 hp when floored.

I assume they are using a mass/distance/time type calculation to work out the power but like you, not sure how accurate they are

I don't think they were racing. Just a quick side-by-side acceleration up to the legal limit.

And to say you need the extra power is ridiculous I'm afraid. The standard car has sufficient power for safe overtaking. Another 35bhp isn't going to make much/any difference.

And for reference, I came out of a car with 507bhp. It was too much for UK roads (as highlighted by multiple trips to Germany where it really shone).
