1) Is there a BOV from the factory in the installation ?
2) Regarding the hood latches ( female parts), did you paint them, since they are galvanized parts from factory I think ? Or you had them re-dipped in zinc ?
3) Was the car dynoed ? Results ? Can you post graph ?
4) What is the engine oil temp reading on the Alpina digital gauge when at operating temperature ?
5) What type of gear oil do you prefer for the Getrag 265 ? 
6) Can you explain the functioning of the Ladedruck ( boost control ) knob between the seats ?

Thank you!
 
 
 
 
 
 
Sorry for the delayed reply Montreal, I haven’t been on the forum in a while.

1. No blow off valve from me or the factory, just a waste gate.
2. I zinc coated the latches then dipped in clear/light blue chromate. Not stock but I like the look and it’s very subtle and won’t rust.
3. Not dynoed.
4. From memory, I believe it reads 85C at temp. Next time I drive it I’ll check and correct if this is wrong.
5. I use ATF.
6. It’s been a while since I’ve had the boost apparatus apart but it regulates the air pressure to either side of the diaphragm in the waste gate and thereby regulating turbo boost.
