It is pretty simple. when the n55 came out huge discussion on differences if any when guys upgraded their car. It wasn't easy to notice the difference. With the B58 guys who upgraded from the 335 to the 340 more or less all say it is a noticeable difference. Do a search and read multiple threads of new owners who are suprised by the new engine. Same with all the reviews.
I am not just saying this because I might be getting a 440xiGCMsport as the order has not gone in yet since they screwed up my 435i order and I might just wait for the new 5 series with the V8.

I'd probably disagree. An N54 car is probably every bit as fast as a N55. The 340 is the first to really compare and surpass the performance of the 335is.

I have a 335 and a 340 in the garage and here's my take. The N55 is a good engine and the MPPK makes it even better. Dyno graphs don't lie and it is proven the 340 puts down more power to the ground than a power kit 335. Are they close in a race? Yeah, it isn't a slaughtering... but the 340 is going to pull away every time. The 8HP50 in the 340 gives it another advantage over the 8HP45 in the 335 with reduced parasitic loss
This comparo is pretty typical when a new model comes out. Existing owners love their cars and refuse to believe the new car is faster. I just wouldn't want to line up next to a 340 at a stoplight and think I was going to outrun it. That's not going to happen.

The B58 is probably a better motor, but I owned a N54 e92, and a 435/335 PPK back to back. The n55 was faster off the line and it was because of the 8 speed. I also had the PPK on my N54.

Not true. Auto vs auto transmission I've done 13.1-13.3secs mppk, and N54 13.5-13.6. When I was FBO minus IC vs a tune+DP N54, they ran 12.8-13seconds while I ran 12.6-12.8.

BMW will always progress with their engines, not go back. The B58 is better than the N55 as the N55 is better than the N54, but not by much.

This says it all.

I thought it was common knowledge that the N54 (the E90 335i, correct?) was a little more vigorous in power delivery than the N55, if not as reliable. I'm not blown away by the N55 in my 6MT though all I'd ever driven previously were 8AT which are quicker regardless.

While agreed on the last part it's too hard to compare 1/4 mile times on the Internet and gain anything from it. I'm not denying you may be running a few tenths quicker than some N54 cars; I was merely stating a N54 335is with the DCT (more comparable than the 6spd auto) is every bit as quick as a MPPK N55. My point was really there not being much difference between the N54 and N55 world... Stock for stock that is.

For comparison a member on here took his 340 to the track and ran high 12s at 109-110. Going back to the original part of this thread that points to the B58 cars being a tad quicker with better top end. Either way the only way to really compare is get 2 cars to the track on the same day and run multiple passes. Either way these are all fun cars

The e90 switched to the N55 the last two model years.

I think Vegetable just wasn't thinking and being biased towards his 435. You are correct about the drag strip and running side by side ,but like I said earlier logically the b58 and the n55 with mppk have similiar numbers almost identical, but the b58 was designed to have quicker throttle response by eliminating the lag which is quite evident when you drive it. Then you add the better breathing top end all the way to redline and it is easy to see why the 340i is faster. That also explains the higher top speed at the drag strip. You have to be a fool to think the n55 is faster and not to feel the difference. I have yet to come across a 340i owner who had a 335 and didn't feel the difference. I don't see anyone besides Vegetable coming here saying the same as Vegetable either.
I am suprised we still don't have any videos of a 335 vs 340i videos yet.

[Tyresian]

On the subject of the B58 breathing better and having better throttle response, does it come with a better stock charge pipe than the crappy plastic one the N55 is paired with? Possibly a wider down pipe as well? I haven't seen or read anything on this yet so just curious.

It's the intake cooling system that's completely different, similar to the S55
And yes the charge pipe is supposed to be much better

I hope that`s true about the charge pipe being improved. The blown charge pipe thread in the N55 section is pretty active these days haha

Ah, gotcha. My experience with the N54 was with early model E90's.

I still have my 2006 330i 6MT and was SO aggravated when BMW replaced that engine after ONE YEAR with the N54. I got a 2007 335i loaner one time (8AT admittedly), and it was scary fast. I don't feel that way in my N55 at all, but it's a 6MT. Anecdotally, all the techs at my local dealership lament the lack of urgency of the N55 compared to the N54. I have yet to drive the new 340 with the B58. I may regret it even further!

The DP on the N55 got a 1/2 inch larger on the 2013+ models

You're right, I wasn't thinking - responding to anything you post.. oops

I was just reading that, pretty nice. I have my 2015 335ix on lease and I'm planning to get the MPPK installed this week, finally got my dealer to make a deal, it was a very frustrating process is all I can say on that, lets see if they hold to the price.

And I know investing in a leased vehicle outside of lease is throwing money out, the way I sit it with how I've bought cars and gotten rid of them after 2/3 years in the past... It is all the same an doesn't matter, the money is gone but I get to enjoy what I'm paying for which is what really matters. Had a guy telling me just to wait 2 years and get a better car... You can always play the waiting game, but if you can afford it, why not do what makes you happy? 2 years is a long time and who knows how many years I'll have before having to deal with kids in a vehicle, dogs can be enough (have 3 small/medium dogs).

Anyway for my 2015 335ix, I'm thinking of doing the charge pipe and down pipe. As long as it wouldn't hurt the lease turn in. And hell maybe I'll buy out at the end if they offer a deal, though it is unlikely, I'd rather go 440ix GC or if they do a M240ix GC, love the coupe but back doors may come in handy.

This.

N-54 First release was very strong. About the next version was scaled back quite a bit. Last version split the difference between them. 335is N54 was a standalone with a different ECU & factory timing package & was the strongest N54.

Think the were 3 flavors of N55 (had stopped paying attention) Original was weaker than the N54. Next version was middling & just short. Last version with the 4" turbo exit & electric waste gates was very close if not stronger than the best N54 save the 335is version. The is also had the 7DCT which helped move it along nicely

No reason to think the B58 is not stronger than the early N54's. Will see if they stay that was or if its deja vu all over again & the dial it back a bit after the new wears off & the magazine tests are over.

N55 MPPK/MPE is variable because there are two versions, ECU dependent, of it early 320HP late 335HP

I did the same thing. 39 month lease and I added the power kit since you cannot residualize it. Worth every penny

Nice.. Does the MPPK help reduce the turbo lag or is it still there?

340i vs 435i

340i vs m235i

[DS_BMW]

340 is dead even with m235. Much quicker than the 435.
