Best power adders + who has the highest HP NA?

I have a 06 330 that I use as my daily driver. It is paid off, so I just want to make it more fun to drive.

I am doing an AA Stage 2 flash along with suspension modifications (H&R springs/m3 sways) I am also putting some rack RG8 lightweight wheels on.

I already have air scoops, K&N panel filter and charcoal filter delete.

What else is there to do?

Who has the most HP NA?

A less restrictive exhaust and headers.

I pretty much got ALL the possible options in my car, except for the headers.

^not completely true. NA engines need back pressure or else you lose low end torque, obviosly not to much back pressure but you dont want straightpipes either. when i have the money to do it i plan on a 3 stage manifold swap, catless headers, and a 75 shot of nitrous. its been proven that nitrous is safe to run in the n52. is is the most cost efficient way to add power before dropping thousands on a supercharger

I have a few friends with 335s. With my buddy's stock E90 335xi I can almost keep up with now. He can take me on take off but once we're rolling I am pretty much up past his mirror and he can't pull on me. Before the tune and 3 stage intake mainfold install I would be very close to his ass but couldn't pull past that. Now my friend's modded E90 335i still destroys me, just not as horribly.

I could see you staying close to a stock IX. I've managed to fair the same against them. I can hang with a stock 335i fairly well too. Modded 335 and Im dusted.

So, stock, your 328i kept up with a stock 335xi (being at his ass)?

No at the time I already had a PBX, intake, and exhaust installed. An stock E90 335xi is not exactly a rocket ship.

Where is it proven? Everything ive ever read says backpressure is bad because all it is is leaving burnt. Gases in the cylinder chamber which messes with afr's.. All situations (bigger exhaust eg) improving flow, as long as back pressure isnt WORSE makes more power overall


There's a 130i in the uk apparently at 335~ (w?)hp.. Custom ITB's, custom flowed head, custom cams and a motec m800.. All N/A, no nitrous.


I'd also like to read about nos being safe in n52? That sounds like its be interesting to read!
