And, again, for the purposes of which car will be able to make more power, the initial statement of the turbos being different is incorrect. Sure BMW may have put some in the mix, and a new turbo came for some LCI vehicles (see the F35 still using the same turbo used on a E90 on its LCI version, for example).

So, again, what you're saying is true, but one can't take it face value that because one is an F30, it'll automatically be "faster" like the other guy said (he said E90 had a narrower power band and less power).

I definitely see what you are saying..

I think the biggest difference that matters in that race with E90 and X3 F25 is the 8-speed transmission in the X3, which is obviously superior

Also I do believe the turbo is slightly different but it might just be in the turbine part itself and not actually the housing and design. The part numbers are different, so there must be something that is different about it.

Actually on Realoem.com under my VIN it shows part number 11657636426 for the turbocharger that is used on X3/X4 35i models. I'm pretty sure these have some mechanical differences.

But the X3 is so heavy though lol only tuned to be compared to a similar 3 series.

Many factors at play, and the 8 speed vs a manual and AWD vs RWD will definitely be major components in a drag race.

My tuned 135i cannot even read the licence plate of my stock X3 28i...

...In the winter

Haha, at first I was like what! Got me with the winter comment lol

The first time I drove my X3 I fell in love with the 8-speed, it is better than the DSG in my Audi S4. Are there any TCU tunes available for these tranny's yet?

X3 can be made into a little year-round animal with PS1 upgrade.. perfect for daily!

In all the time I was drag racing (quarter mile), I never had anyone ask "what was your 330 foot?" Besides, in your scenario you still lose and the other car is pulling away.

FWIW, it is possible to design a race between a human and a racehorse where the human wins.

You didn't say anything about FASTER - you claimed that an E series and F series N55 was identical - you are wrong.

(per my vin - car is NOT an LCI)
