What is the N55?

Alpine335TT · 02-07-2010, 08:49 PM

Can someone please clear this up for me. I've been reading up on this a bit and I'm still confused as to whether or not the N55 is indeed a single turbo motor.

Yes

noro · 02-07-2010, 08:56 PM

yes single physical turbine. 2 separate exhaust channels spinning the one physical turbine hence the "twin scroll".

If everyone searched all the time, there would be (almost) nothing to post. If you don't like to read the topic, just skip it. It will be gone in a day or so most likely anyways.
