После замены едет быстрее

А затем что м52б28 задушен.


Результат в купе с м50 коллектором, модифицированым впуском перед дросселем составил 15.1 квотер и 6.2 до сотни. При более удачном стечении обстоятельств 14.9

I pretty much just flushed my coolant, cleaned my engine very detailed and cleaned the m54b30 manifold completely.The swap is straight forward, everything is reused again or could be replace with new parts. The m54b30 intake manifold itself is bigger and has longer runners than the m52tu. The first 80-100 miles the car seems to adapt itself to more air flow. The difference is completely different at all rpms. The car just revs freely all the way to redline, no more choking.Well worth the 8 hrs of work and about $400 spent in everything.Any questions feel free to ask

It's to help you make a bit more power by changing the intake manifold on your Mx series engine. But which one? You can recall above I thought the B25 was a better manifold, but it seem I was mistaken, as someone took the liberty of dyno testing the M54B30 manifold on a the M54B25

"Test vehicle E46 325 with M54B25 MY2001. FInal performance: 142kW/ 193hp following DIN70200 (Bosch LPS 02).

Changes: Intake manifold from M54B25 exchanged for an intake manifold from a M54B30.

(translated for you)
*Final performance: 145kW/ 197hp following DIN70200 (Bosch LPS 02).

Maximal perfomance difference compared to the standard intake is 6,5ps at 4300 RPM.
Here are some comparisons between the two dyno charts:
performance difference in hp at Rev:
4.5ps at 3300 RPM
2.0 3640
4.2 3980
6.5 4320
4.2 4660
3.7 5000
3.3 5340
3.5 5680
4.2 6020"

Needless to say, if you have a M54 powered car already, don't switch. And if you Have an M52tu powered car, grab a B30 manifold if you can, otherwise, I doubt you'll miss the average of 3.5whp across the board.

*Cliffs
M54B30 manifold is the best manifold for all M52tu and M54 powered cars, though a M54B25 manifold will work well too.

народ дайте чертежи переходника на дроссель если есть у кого на почту seidl@mail.ru, купил впускной коллектор от м54 3.0, буду колхозить... а дису без вариантов менять или можно с 52го мотора воткнуть?

максимальный приход 6,5 сил? в чем прикол то?
