BMW E39 528i
I've got a neighbor with a 2000 E39 528i that hes put a decent amount of money into. He's under the impression that with pulleys, CAI, retuned DME, custom magnaflow exhaust and headers that somehow his originally 190hp/210lbs ft torque car is now some kind of bahn-burner. He was bragging about how he's gonna be near 270whp just based on those mods (he may have said cams too). Regardless I'm heavily skeptical and think hes just retarded... my question is... what is the estimated REAL power output of that engine fully modded?
I searched google and dragtimes but couldn't find anything with similar mods really.
