N52 Comparison


I have an E92 and the wife an E83. Both have the N52 engine (N52B30 to be exact)....but each is tuned slightly different.

My E92 has a rated 230 HP while the E83 is rated at 260 HP IIRC...

Having both in my garage, I can say the E83 is very much more responsive.. Not much more powerful, but definitely more throttle responsiveness. That implies (at least to me) that there is a way to "tune" the E92?? Maybe this is what installing a JB would give me??

From a Wiki I also saw the statement below which may explain it straight away:

*output changes result from the omission of the variable resonance system, dual plenum intake runner system, and the variable back pressure muffler.

Any other thoughts for me to brew on?
