Is our fuel pumps making our cars run weaker? - BMW 3-Series (E90 E92) Forum

Is our cars fuel pump one of the limiting factors for more power? With so many pumps failures would a better fuel pump allow for more power to be extracted from our engines and if not perhaps help with the longevity of our fuel system?

Control over the fuel pump, and bigger injectors would be a big help. It would also let us run normal meth kits and not $1000 ones.. The combination of bigger injectors and a better fuel pump along with bigger turbos will make 500WHP in the 335 a reality... IMO... By the time that happens though I'll probably be in a modded GT-R

There is no replacement for the high pressure fuel pump right now. It's not a generic fuel pump..and is only made by BMW. It's around a $1,300 piece from the dealership. This is currently all of the x35's main weak point.
