Interesting read...

Paiseh if repost!

F30 320i vs 328i engines - Part number comparison - Bimmerfest - BMW Forums

Wonder besides pistons and a more aggressive tune , the power comes from where else.


That post is outdated. The pistons are different causing the compression ratio to be different. That post still says both are running 10:1 ratio.

It has been proven by opening up the engine and looking at the piston dome. The 328 is 10:1 ratio and the 320 is 11:1 ratio.

The higher cr on the 320 do not allow higher boost and it runs a different fuel mapping.

Basically, think a NA ENGINE with 11 cr. now u want to turbo charge it. U can maximum run say 1 bar. If u want higher boost, either use higher octane or lower compression by using thicker gaskets / change pistons.

x20i stock = 184bhp/270Nm = more than enough

those who desire for some more power
x20i conservative tuned (20% up) = 220bhp/320Nm = best bang for the buck liao
