In reality it is about the same performance if anything a little better. BMW did not make the N55 motor to out perform the N54. They made it so it lower CO and helps the environment and with their advance technology they were able to do that and keep 300Hp mark on this N55 engine platform.

To hell with that graph. I've seen it and it is shit.

But I was trying to tell you and everyone else, It does not suck ass, The difference is in High RPM maybe somewhere around 4% loss of power. It is not extreme difference between the two. For your information My last car was 2008 335i (N54) pure stock motor. My new car is 2011 335i Xi Pure stock. I have notice some slowness but not like the way you guys explain and bash the N55 engine, and if your N54 was fast enough and it was still in a good shape why did you upgrade?

First off, if you read everything I've written... I am one of the people here trying to defend the N55 for its potential, I think it will be a great engine.

Second - It certainly wasn't me who said the N55 sucks ass and I did not start this thread - check your facts.

Third - Other way around, I first had an N55 in mid 2010, then got an N54. When I got my N55, I drove it around a little while then hopped into a friends N54, where I felt the difference and after much deliberation was able to have someone take the lease over on my N55, since there was no value loss there, it was no problem for me. Had I bought it, I would have been f-ed...

I'm not going to research anything, my experience is exactly the opposite of yours. My N55 feels gutless at lower RPM, when I drive around normally on the streets I am getting taken off the line by minivans unless I really stomp on the pedal. That is not the case for N54. N54 felt like power delivery was immediate. Perhaps the power feels different from engine to engine? I don't know. Some stock N55's have Dyno'd as low as ~240whp, while others as high as 266hp. That is why I said the graphs are shit.

taken by minivans? Lol. OK there chief..

My stock n55 would break loose around 30mph as seen here..

with how much time has been spent on the N54 motor compared to the N55 motor i wouldnt say so. were at about a 15% loss compared to the N54.

Well I know I am makin 400 whp..more than any n55..

You should not get angry about being slow in the brain. Also doing more research might help you become a little faster in the head.

Provide some facts where are those Dyno'd cars with ~240whp and as high as 266hp? Do they use regular gas in their 335i? Maybe they should read the user manual. They are also part of that slow group of special people...

Good Luck to you..

I don't know why you have to resort to insults. I did not do the same to you. But I'll answer your insults nonetheless. All these proof you're asking for, I'm not going to get for you. You'll just have to believe it or not. Somewhere on this forum someone mentioned his stock N55 pulled ~240whp. Your very own graph that you linked showed 266whp. I'm not going to a track or a dyno. I don't have the time and its not my priority in life to take time out of to do so. And anyone else who takes their car to dynos are not going to put regular gas in their tanks, I'll give them the benefit of the doubt even if you won't.

You say I see things in slow motion? Thanks, that is supposed to be a compliment. Because people that really do, are extremely gifted and do all kinds of important shit. You'd have been better off calling me something else. And research? Research what? Believe everything you read about on the internet? Or believe what I experienced myself as I've driven both N54's and N55's. I'll bet you're one of those people that would rather respond to a newbie telling them to search when in the same amount of time you could have answered their question. You're just a Grade A Asshole

+1 Bz seems like a troll and that's why I've ignored him. None of his posts make any sense, all he's doing is regurgitating things he's read on the net...

Just stirring...

Anyway... having access to a workshop who tunes BMW's, I've had a chance to drive quite a few N54's and N55's - I think they feel different (N55 more turbo like, N54 more naturally aspirated) but I can't say I agree there's any large difference in power, acceleration.

If you're being serious about struggling to take on minivans, maybe get the car checked out? End of the day, it's a turbocharged 3L straight six - that's not exactly a low powered engine regardless of twin vs single turbo.

Personally I think the N55 does feel faster stock, it has more of a surge down low and feels a bit more free revving but I prefer the power delivery of the N54 - really smooth, linear.

Had a N54 for 3 years, most of that time FBO then stock for the last few months. Ive had my N55 for a month and it definetly feels faster then the N54 stock. I know once im FBO on the N55 it wont be the same as my N54 but in stock form the car performs well.

almost 20,000 km 07 model never had fuel pump problems, i guess the american release was different from the german?

20 000 km is nothing... the fact is the N54 eat injectors and HPFP, I know people scared to take their n54 for vacation because the N54 is an unreliable peace of shit that break without notice... Who want to be in limp mode 300 milles away in a shit hole with the wife and children on vacation? Who want to lose 3 days to replace an injectors and diagnose this N54 300 milles away from home? This is sad but instead of taking an N54 on a long trip I would take my wife 2005 civic before... his civic outperform the n54? hell no, it barely make 130 crank hp! but it wont let me pants down in a shit hole during vacation.All this "the N54 is better than the N55" because your butt dyno tell you the N54 pull 3 hp harder pffff who cares?

so in my book the N55 is a better engine. Simpler=better. I dont need two tinny ass turbo on a 3.0l, and every part in double, to make it perform.
I preffer a simpler reliable design that WORK and if I have to gives 5hp in the process for this than it is fair for me.

Shit hole, maybe not the best term, but for me= a smaller place in the country to take vacation like in Maine, NH, Vermont far away from home(big town). I wouldn't like to be in limp mode in the middle of a mountain in Maine or NH with the kids.
