Hey guys, I just bought an 2000 A4 quattro. its the 150 hp model I believe.

Does anyone know at what RPM the turbo kicks in?
And how long do you idle for the turbo to cool down?

Thanks

 

Not sure about when the turbo comes on, but the OEM turbo is small and comes on pretty fast - you probably don't feel it. I'd imagine it's somewhere around 2500RPM or so. As for idle time, drive out of boost for the last few minutes or idle the car for 30 seconds to a minute or so, and you'll probably be fine (maybe longer if you really cane it while you're driving).

 

the turbo basically spool at idle... There is no lag basically

The turbo is both oil and water cooled and doesnt need to let idle for more than 5-10secs if driven easy the last min of a trip. If driven hard then parked, give it 30secs

 

Ya...

what cincy said... not exactly a part that goes "on" and "off" with your rpm's.
