| Hello,
I just recently picked up my first BMW - its a 1999 323i. Its in fastastic shape!
The previous owner had a few mods done to the car, and while i've done a little research - i'm having a hard time figuring out how much HP this car has over a stock version.
The mods:
Dinan Cold Air Intake
Dinan Stage 1 software
Turner Motorsports power pulley upgrade
Might be worthy to note that all these upgrades were done at Turner Motorsports.
The question - what would the approximate HP gain be from these mods? i believe the stock hp was 175(?). So i am guessing that after these mods - its right around 200hp.
Any thoughts? I'm not looking for an exact rocket scientist measurement - just ballpark.
Thanks in advance,
Mike the new |
