RPM Shift Gear n54

[leonardlator]

I have a 135i n54 which clearly is manual and I would like to make an inquiry to the owners of these engines, or someone has knowledge.

¿In a DragRace at how many rpm do you shift the gear ?

I Understand that this type of car comes with two turbos that handles a range of revolutions of the load of Turbos, I'm go to explain best: In 1100RPM the turbos are activates, 1200RPM and until 5400RPM the Turbos are loaded and activated but then 5500RPM the turbos are discharged and I'm not get the same power and efficiency. At least that I know, I have taken this to the track and I think that went well, but would like to know your opinions.

Shift at redline if you arent sure, adjust as needed. The turbos dont lose boost at high RPM fwiw
