We need two identical cars - both sedans, both rearwheel drive and both with identical transmissions, one with an N54 and one with an N55, this needs to be isolated to only one variable and that is engine.
yea thats true. In another comparison though, i raced my friends 2011 335is with a front mount intercooler and dci when i was stage 1 jb3 with only intake and it was pretty similar, his maybe a smudge quicker esp from a dig. From a 60- 100 + run. it was very similar.
