Not much to say about the 330d really. It being FI, the exhaust makes less difference. A decent remap on a completely stock engine will take you from 230hp to 300hp, approximately. That can be done with the DPF still functional. Above that you can go a bit further by adding a hybrid turbo, and I think it's at that level that the DPF needs to be removed (plenty remove it sooner, or even at stock power, but it's not necessary). The stock exhaust manifold is pretty nasty and can be replaced for a couple of extra ponies, but no major gains there either. I haven't seen any mention of modifying the exhaust behind the DPF at all, but people do it eventually. There's only a small box on the stock exhaust between the DPF and the rear muffler.
As for altering the exhaust for sound, I've never paid significant attention to that. I don't think we need to worry much about drone on the highway; 80mph is 2000rpm on a 6mt. And too much exhaust just results in tractor sounds eventually. Last edited by Tambohamilton; 04-02-2023 at 03:42 AM.. |

330d
Tam, I am going to take my diesel questions over to your build page if you are still monitoring it.
What year is your wagon? Is it auto or manual? Is it RWD or xi. Is the diesel engine an M57 or N57? Form your thread, you advised that the diesel engine was approximately equal in weight to the turbo 6 in the 335. Is the back of the wagon any heavier than the diesel sedan? Is the engine the only thing that makes the diesel heavier than the petrol equivalent? I have a 328 sedan (salon) and I am trying to correlate comments from your build with Biginboca who has the 328 coupe. I can find total weight differences between cars, but not axle weight differences. Peter |

Yep I used a dremel with a carbide cutting tool. Worked like a charm!

Agree to disagree I guess, I'm a much bigger fan of flying under the radar. I like for modifications to mostly go unnoticed unless someone is an enthusiast and looks closely at the vehicle.

I agree with this. That’s why I got a stock style carbon hood and a low profile carbon trunk. I was thinking I could paint them and have a pretty stock looking sleeper.

Hood Vents
Ok, Since we are talking hoods, I have a question for the hot weather folks:
What is the current thinking on venting the hood behind the radiator to allow heated air to exhaust? It appears that the science is sound, although it would definintely not contribute to the sleepper look, and cutting into a carbon hood would require some guts. I am wondering if hood vents would be a no-weight-gain solution to improved cooling. What I don't know is if there is an aerodynamic penalty on the highway at "Nevada" speeds. Peter |

nope, unless the car and chassis were setup for that youre doing more harm than good. only time aftermarket hood vents work is if the chassis known to run hot, usually by cramming v8 or larger into a small engine bay.

By design these cars run hotter than what people seem to expect. It’s for fuel efficiency, not some unexpected cooling issue. The radiator fan and cooling profiles work to keep the engines around 240-250*f. When people come from other platforms they seem to think that a larger radiator or cooling mods like high flow fan are needed. They aren’t needed, instead if you want to make the engine run cooler start with coding the radiator fans and water pump to run cooler. Start with software that can make the difference not the hardware you’ll only be fighting the software. The only engine cooling mod I have done was add an oem N54 oil cooler and even with that I’m still running the oem oil thermostat and no software changes. I’ve not had any cooling issues with that set up even on the track (granted at sea level). At the end of a 20 mins session running 5500-7500rpms I’m seeing oil temps 260-265 tops and never had a limp mode.

Measuring Engine Water Temperature
Regarding monitoring engine temperature; What is everyone using? BMW in their wisdom chose to delete an engine temperature gauge from our E90 cluster.
I would be interested in monitoring water and oil temperature and would like a warning of loss of oil pressure. Peter |

The reason BMW deleted the gauge and/or substituted oil temp was once they installed electric water pump/thermostat which responds to engine temp needs (rather than running constantly) it resulted in very wide variations in temperature. This frightened owners who beat a path to their dealer to report something was wrong with their engine...when it wasn't.

You can enable the "secret menu" to show coolant temperatures, but it requires a lot of button pushing and you have to repeat it every drive: https://www.carsaddiction.com/articl...er-hidden-menu My radiator fan is a little glitchy right now (code 2EFF) so I am using bimmer-tool app on my phone and a K+Dcan cable to monitor coolant temperature: https://play.google.com/store/apps/d...hl=en_CA&gl=US Note that the water pump operates in different modes to yield different coolant temperatures depending on the scenario: • 112°C ECO mode (economy) • 105°C Normal mode • 95°C High mode • 80°C High + mapped thermostat mode Also worth knowing what temperatures are considered overheating. The car will start to reduce power at 117°C coolant or 148°C oil, then overheat at 125°C coolant or 158°C oil. See attached for more details. Last edited by The Nightman; 07-15-2022 at 05:18 PM.. |

Update from Biginboca
Alphonse,
I hope you were spared the worst of the recent storms. Has your racing season started up again with cooler weather? Any updates on the car? |

Hey, Biginboca,
since your home track closed, have you found a new one to frequent? Homestead, or maybe Sebring?
