Hey guys, new to forums with a 128i ive had for about a year and a half.
I thought I would share with you the power im getting my from car.
2010 128i
slicktop
base everything + sport package
6mt
131k miles
We pushed 248whp and 207wtq at BPC
The car car has AA headers, N54 manifold and throttle body, 3" stainless intake piping to OEM airbox with KN drop in (charcoal filter removed), resonator delete, 135i rear box.
Below is a dyno of the car only, as well as a dyno with another 128i with 3 stage manifold and catless headers with BPC tune vs my car.
So the advantage of using the N54 manifold vs 3 stage manifold is an increase of 24whp and a decrease of 10wtq. Similar setups, different intake manifold and intake.
Next plans are S65 injectors + E85, MILVS, catch can, euro airbox, N55 Magnaflow. Hoping to see 300-310whp.
To see other modifications done to the car check out my build thread!
