Great car considering its price point, great car price point aside. Oh, oh, oh, I love the posts about rear valance design flaws. Yeah... like the M3 rear valance has excellent porportions; maybe to the vision challenged. |

Nice job Scott26 et al. I think it's beautiful; very aggressive. The orange looks fantastic. Would have been nice to see more interior/exterior color options, optional EDC, optional M DCT 7 speed, and optional sunroof (or CFRP roof), but I understand there are tight budget constraints.

yea thats just plain dumb..
i dont even wna start with how they left the hood,trunk, and even engine the same the trunk was badly desighned as it is it needs to be csl style alittle more for it to even look proportinal.. i think they just need to let vorsteiner do a few minor alterations on that and the hood and noone would be able to resist buying that

You mean current durability? Because I have yet to hear of a piggyback tuned N54 requiring any MORE maintenance than any other regular N54. And are you saying that merely the "better" intakes and exhaust added 50/lbs of torque(catted as well)?????? Uhhh...no. The boost has been increased pure and simple to make the bulk of that extra torque. |

This photo was taken in SF city. Unless it's a complete photoshop, no one caught it during the take?
After some investigation, they did some major photoshopping. I believe the original photo was taken at Sansome and Pine. You can see California St. sign after Bank of Orient's sign. Match the location and perspective on Google map, they kept some of the original building structures, added some and modified others. A tell-tale sign comes from the stone works below the windows on left hand side. In Google street view you can see the same window but BMW photoshopped out rest of the window with the same brick pattern.

When you use terms like "de-stress" the engine I get the distinct feeling you have no idea what that really means. All BMW has revealed thus far is that there are tighter internal tolernaces. So what does that mean exactly? Less clearance between the piston and cylinder wall? Smaller ring gap so that less combustion blows by? Tighter spacing on the crankshaft bearing? Did they polish and port the valves? If you use some logic and stop repeating the mysterious marketing, the additional cooling components are probably the primary reason they can produce a bit more horsepower via software changes and still have a reliable warranty. More power = more heat >>>> needs better cooling, which they have done already in their performance kit via a secondary radiator and a more powerful fan. Blueprinting an engine to tighter tolerances may free up some revs, but I don't see the redline being any higher in the 1M than the 135i. If you know so much about the engineering side then please do share.....otherwise you are just throwing out ambiguous terms to puff yourself up. |

Isn't it possible to change motor compression with a change in head gasket thickness? Isn't it possible to change compression by using parts with higher tolerances (reduced variance from standard) such as valves, pistons? Isn't it possible to increase rpm or provide less stress on the valvetrain by increasing valve spring rates? It seems to me that you listed several methods for improving the build quality and power potential with the minor changes to internal engine components. Isn't it possible to reduce exhaust gas temperature readings by changing the tune? For example leaning out or richening a cylinder? I am curious to see how much boost is changed, but it does seem to me that a fair amount of power can be made by improving the components used in the build, which then of course then increases the potential once the boost is dialed up. I'm curious to see what boost changes were made. Last edited by M3 Adjuster; 12-12-2010 at 12:38 PM.. |

Would'nt the easiest way to increase VE, would be to increase boost?
Based on the timeline BMW had to create this car, and based on the similairities to the output of the IS engine, one possibility is they took the same engine and put it into the 1M. Does it really matter if they didnt do anything else? I am not sure how cost effective it would be to create some "special" parts to make the engine in the 1M unique. But, I am certain this would not be to their advantage. If they did do this, I would expect the output to be at least marginally better than that seen in the IS engine.

A bigger intake and maybe somewhat less exhaust backpressure (which is hard to do with cats in the way). Sure, I guess you can call that de-stressing by improving volumetric efficiency since the engine is just an air pump anyways. But once again, it's obscure marketing terminology. Most aftermarket intakes/exhaust allow the turbos to boost more easily by reducing drag on the airflow. Is that de-stressing? Well yes. Except for the fact that adding more air adds also adds more fuel which then has the unfortunate side effect of creating more power. And that then creates more stress on the engine. So how is that de-stressful? I guess it depends on how you look at it. Which is what i don't like about the use of that term......"de-stressing" it can be quite misleading when used in isolation to look at only one side of the VE equation. And if adding a bigger intake and exhaust is considered a feat of engineering....well there sure are a lot of engineers on this forum. In any case, I don't think they have done anything radically significant to the N54 engine to make another 30-40 horsepower. Looks like another implementation of the power kit with the oveboost that comes from the IS platform.....just add in a lot of marketing hype. In any case you have answered my question which you don't think was a question at all. |

I am not a mechanical engineer....but exactly how does the same engine with the same displacement make an extra 50ft/lbs with only intake and exhaust? Explain it to me in laymen's terms please because i don't understand the super-technical mumbo-jumbo....

Thats more of a aeroengineer's job but as one I say that without a change in the A/F ratios and with cats its not really doable.

The additional engineering you are talking about so far consists of what? Better intake/exhaust...and what else? Like I said before the bulk of that torque is coming from increased boost...there is just no other way it is possible with the same N54 engine (note that is NOT N54 sourced..it IS a N54). |

I believe this answers the question of why BMW did not use the full potential of the engine in the 335. They had to have some room for the M cars.

January issue of C&D is quoting a price of $43k for 1M.
Also if you base the percentage price difference of US M3 coupe prices to UK M3 coupe prices, the 1M price comes to just under $44k as 1M in UK is 39,900 pounds. |

The first thing Dinan does is to call BMW and de-register your warranty. Once you are tuned via Dinan, they take over your engine warranty from BMW. Dinan doesn't do anything radical to destress the engine in order to prepare it for more boost. It's mostly a software upgrade. You can also purchase their 3rd party intercooler and oil cooler if you like being price raped......but that is no engineering feat. Most of the members who mod on here do exactly the same thing already so how is adding on aftermarket parts an example of good engineering? It's just common tuning sense that has been around for decades. As far as I am concerned, the only significant change going on via BMW is the secondary cooling system they attached to the power kit and the fact that they pulled out a couple of degrees from the timing curve. That was an example of good engineering that takes into account the additional heat being generated, but it's not like they threw in lower compression pistons or swapped out engine internals to compensate for the added boost. I guess you missed some of the earlier posts that indicated people who had purchased the BMW power kit experiencing limp modes during the initial releases. And don't even get me going on that other famous example of BMW engineering - HPFP anyone? In BMW we trust Last edited by Ilma; 12-12-2010 at 07:24 PM.. |
