Worlds fastest XUV 620i

[Yooper1]

Today My 620i went 35.3 MPH under its own power with out throwing any codes. I am the fastest person alive to do this. No one shall pass me, I am the passer! :cool:

For real though, 35.3 MPH. Thoughts?????????? Lets hear them.

Well I have a 850D and it will go 36mpg.
I use the belt from the 629i, which is slightly shorter and therefore I get a little more clutch shift. I also have 27 inch tires.
It is now significantly faster than when it was new, 29mph was it's speed.

How did you get passed the speed sensor?
and the belt was from a 620i?
we need to talk.

There is no speed sensor on the diesel, sorry I can't help you.
Certainly oversize tires will give you more speed, but they can also take away some of it's snappyness if the tires are heavier.

kinzepower; did you have to do any modifications to go bigger than the 25" tires? i have an 08 diesel and would like to put bigger tires on too if modification is not necessary or minimal.

Vipertblck,
I have '09 XUV. I putt 31" tires on it last summer. I had to do a little trimming on the frame behind the tire and put the 2" lift kit (if you want to call it a lift kit) min. rubbing, but working on a custom lift now.
