Nope. It's the same engine as the Z4 35is. The S54 was in the E46 M3.

Isn't the engine in the 1M the N54B30TU? I know the last two letters/numbers are important and for the 1M they specify that the engine is a High Output version.

EDIT: I retire my previous statement. I was under the impression you were referring to the 135i and then I came across your other posts referring to other platforms. |

The DCT weights 50lbs+ more than the steptronic and 6mt. I've owned the N54 since it came out back in 2007 and was one of the very first to run a tune. I've owned both the 6mt and 6at and have driven the DCT. Believe me the shifts are quick but not that much more than the steptronic's 300ms gear change. Gotta love people who just hop in the game and since they have th newest model they think they are the best, know more, and have seen it all. Oh and i've ran multiple N55's stock for stock and let me tell you first hand the 6at rips a shorter 60ft time each time despite the N55's sophisticated launch control. Now I'm not saying I had a huge lead but a good half car to a car up top. The N55 just got here, so give it some time and there's no doubt it will be right on par with the N54 goodies.

Hey, you're in FL, assuming stock for stock (only power mod is BMW Performance Exhaust), let's arrange a track meeting. By the way, kinda hard for me to kneel down when I'm already above you. |

Again my post was intended for those that were simply laughing at the thought of an N55 losing to an N54? We all know that the N54 is capable of producing more power right now due to the fact that's it's been in production much longer.

Looks like some ppl are ignoring the fact the video showed a MANUAL vs a DCT...
The DCT is quicker than a manual, period. However, I would like to see a stock auto N54 vs a DCT N54 (335i were avail with DCT in 08 I believe in Europe). |

It would need to be a roll on. Way to much driver error involved in a manual launch.
From my local drag strip (elevation of 5280feet), my stock 2011 N55 6mt runs were dead on with a 2009 N54 Steptronic. (13.9's) With the JB3 stage 1 tune my car was .3-0.4 seconds faster.

From a roll, we started at around 40mph, dead even until about 105-110 where his bumper started to pull forward on me. We let go at 120 and about half of his car was obviously slightly ahead of me. I'm guessing due to quicker shifting and more aggressive gearing. To me these are interesting findings because regardless of the abilities of both cars, it all boils down on how they are driven. |

Their was an explaination of this when DCT first came out on the M3, and from what the video explained DCT has no drop back due to shift time..this is more noticable the faster you go...because the faster you go the faster your speed decreases when you take your foot off the gas. Here is the video that I am talking about. Last edited by Aries932; 03-01-2011 at 12:12 PM.. Reason: Wanted to add something |

My Golf has the DSG box (same as DCT) and I would say the exact opposite to that mate. For example, when doing a straight line drag, the 1st to 2nd change is probably the gear where you lose the most momentum when changing with a manual box. Then 2nd to 3rd and so on. The higher gears is where you have less of an advantage with dual clutch, as the car is going that quick and carrying that much momentum anyway, someone with a quick shift in a manual won't really lose much at all. The dual clutch boxes help not just with the quickness of the shift, but the fact that there is no let up in acceleration, the nose of the car doesn't drop on each change and there's no loss of boost/lag. Something I have found to be most noticiable on a MT car when doing the first few changes (1st to 2nd / 2nd to 3rd ) as you are not carrying enough speed or momentum to help you at that stage. Could be wrong though.. |
