Need a 335d in the Pacific Northwest
Portland, to be specific. HPF is willing to test fit one of their fmic's to see what would be needed to run their unit on our cars.
Is there anyone in that area that could work with HPF for everyone's benefit? |

They didn't get specific, this all happened this week. I think they will probably start with simply visually comparing the i/c's, then go from there. I *think* they are very similar (the 335i and 335d i/c's), even though the part numbers are not the same. If they occupy the same space and have the same connections, I think we will have a good chance of success.

Contact me privately. Let's see what can be done.

Ok, talked to HPF a little bit. I have some tasks this weekend that will allow us to see where things are headed. Cross your fingers...and thanks to Joe for being proactive on this...very awesome.

Lower temps, higher boost! :P

Has anyone yet measured the inlet and outlet temps of our stock IC to see how efficient or inefficient the stock IC is?
A larger IC may actually end up increasing turbo lag unless the car is tuned to run more boost to compensate for the cooler more condensed intake air. Boost pressure increase is not usually a bi-product of increasing the size of an IC, unless there is something different about our cars that I am not aware of. |

In my case, the fmic would preceed a tune, probably from Renntech. I would like to have the fmic in place before I take the car to them for tuning.
Chris, heat soak and retarded timing/lower boost is also a consideration. Every dyno comparison I've seen of the 335i factory i/c versus an upgraded aftermarket i/c shows the factory i/c heat soaking and then timing is pulled. I assume (bad word) our car operates in the same way, and might even be more sensitive to intake temps, since our intake plumbing has a temp sensor, and the 335i does not. I don't disagree with any of your points, but as you know, info on the d is very sparse, so my attitude is "we gotta start somewhere." |

I can relate to the issue of heak soak,,, my point was simply that by adding a larger IC it will not increase max boost above stock pressure. And while possibly helping to mitgate the issue of heat soak during track days or during hot summer months, I would be apprehensive to assume that our engines operate in the same fashion as the N54 or N55, our turbos certainly don't. By their very nature diesel engines run much cooler, so I would not be surprised to see much cooler inlet and outlet temps by comparison with a gasoline engine and it's quite possible that the stock IC is more than adequate. I just think a good place to start would be to determine how efficient or inefficient the stock IC is by measuring inlet/outlet temps under load throughout the RPM band and how quickly outlet temps recover after a hard pull. You might be surprised by the results. In any event, I am all for more options, you know that! If you are heading down this path regardless, and since you are stock now I believe, try and get a baseline dyno done before the IC is installed. I would be very interested to see if the IC by itself (no tune) increases HP's. |
