320i he meant... not 320d. Right out of the box a 320i is faster than a 328d. |

Same horse power but it takes he 320i higher RPMs to achieve that and the the low end torque on the 328d alone destroys it by 96 ft/lbs. Polus the 328d has a high top speed at 142 vs 130. The specs do show a 0.2 increase in 0-60 for the 320i but I've achieved 0-60 in 6.9s so I'm not sure with that. Even if the 320i has a 0.2s difference, beyond that at higher gears the diesel kicks in and would blow out the 320i. I thought you guys went by facts and not opinions?

Facts? It's right there in your screenshots.
320i 0-60MPH = 7.1s 328d 0-60MPH = 7.3s What more do you need? Yes, the diesel has better torque, but I'm guessing you don't have a good grasp on the difference between torque and horsepower and what exactly horsepower means. Look at the RPM for the peak HP for each of those. The 320i is way higher, which means they can gear the transmission lower and take advantage of the torque higher in the RPM range. Don't forget that you're also comparing the lowest end of the N20 with the mid-range of the N47. In Europe there is also the 318d which uses the same N47. The straight comparison would be the EU 328d with the 328i. 328i: 240 hp @ 5,000–6,000 rpm 260 lbf·ft @ 1,250-4800 328d (EU): 181 hp @ 4,000 rpm 280 lbf·ft @ 1,750-2,750 rpm Not hard to see which one of those is going to be faster.... Edit: I'd also like to say, I love a diesel, I've only owned diesel cars since 2004 and have no interest in going back. But, on pure speed, gas engines will dominate because of their increased RPM range. Diesels may feel faster because of that low end torque, but when you're limited to 4,000 RPM you're never going win any races. Second edit: I've found multiple sources that list the top speed of the 320i to be higher than 130MPH. Car and Driver lists it at 155MPH (I don't believe that) Topspeed.com lists it as 146 (more believable) Top Gear also lists it as 146MPH. Last edited by jnecr; 08-03-2017 at 01:07 PM.. |

Assuming you could actually figure out how to do it, then yes, it will invalidate your warranty. You'll also almost certainly get EGR failure - which require the EGR to be replaced, at a cost of (at a guess) $400+ (In the UK, an EGR replacement on one of these is usually Ł300 or so). Again, your modifications will mean that your warranty will NOT cover EGR failures. Please also read my other post regarding the car attempting to do active regens (it'll be picking up fault codes for pressure on the DPF, as it'll be expecting pressures to change, and they won't be), and enough active regens can lead to excess diesel being dumped into the sump. The oil level gets high enough, and the engine goes into a 'runaway', where it starts running on that diluted sump oil/diesel mix, and revs up to the limiter. Even switching off the engine won't help at that point, it will run, bouncing off the limiter, until it self-destructs. So, you want to wreck your engine, with no warranty cover, and a $10k+ bill for a new engine : this is the perfect way to go about it. Do come back and tell us how it all went in a few months. |

No, nobody has done it. Yes, it will completely 100% void any engine and emissions warranty. Yes, it will clog your DPF the first time you use it and your car will go into limp mode, the error codes will be numerous. You will have to replace your DPF which one person listed as a $2500 part, it's likely more than that. If you remove your DPF then you have voided your car's warranty already. So we can ignore that. I assume you'd block your car's EGR as well, if you didn't do this then you will clog your intake quite rapidly. Both of these require extensive coding to remove all the error codes and limp modes that would occur. In short, you're completely on your own, I doubt any tuner would really be too interested in helping you install a "coal switch." However, they can definitely help in removing DPF/EGR and coding it properly. |

Basically, it was so easy to do that the emissions regulators forced the manufacturers to make it a lot more difficult. From what I understand from a couple of people who have looked at the software, it's really heavily integrated into the systems, and designed to catch deletes and put the car into limp mode. In comparison, yes, it was relatively easy with the E90 models. |

Gotta say, I got behind a Golf TDI yesterday. It had a fart can size exhaust, and was just pooring out black smoke. I mean the slightest goose, and it poored out. Silver car, but the whole back end was just sooty black.
Between the 4" plus exhaust, having a black butt, and all the smoke, I couldn't stop laughing. People really think that looks cool?

"Rolling coal" adds ZERO power to it from the point before additional fueling even starts to register visible smoke.. Costs you a big fuel penalty and skyhigh EGT's, enough to damage many diesels quickly (not many can actually tolerate it).
I like as much power as I can get like the next guy, and am no enviro-nazi. But rolling coal even without emissions equipment to damage...just doesn't make any sense.

Well done, folks. This...............literally brought tears to my eyes. I do not possess the patience to even attempt to rectify all the astronomical ASSumptions incorrectly made by ole 'coal-roller-billy'.
I stumbled upon this thread while searching for something else and even decided to join just so I can add a comment. |
