pity cams/turbo kits/aftermarket forged pistons were never developed for these engines 
this is on a 130i, too which is 265hp stock (gets 240-250 to the wheels approx, stock) and i believe... considering the 128i is 230hp... well a simple tune (and intake swap i believe?) will get you +50hp.
supercharger kit if you want +100-150whp at least? :P
so considering 180rwkw from 195 at the fly (super impressive!).. 93% efficiency means 200rwkw you only need 216.6 at the fly, so yeah tune/full exhaust/intake will easily do it for you.
supercharger is apparently 330-350hp atw everything else stock on the lower powered USDM N52B30's... so that's 260kw atw :P. i'd imagine somewhat more available witha 2.75-3" catless exhaust.. |
Thanks, have you done this to your car? Do you have dyno charts to support the power figure?
I was under the impression our cars run around 140rwkw standard, certainly feels to be low-mid 100 range.
Do you have any information on the S/C kit? I have only seen the ARMA kits, which when tested on a Z4 in the states they weren't up to the task.
If there isn't some form of FI kit for our engines, it could be more cost effective to swap in(and engineer) an N54/N55, or S65 if feeling adventurous.
