So I took a red 8 for a test drive at the local dealer Monday, awaiting mine which should be here next week. First drive of the machine... first drive of any rotary I've taken for that matter. When I revved the engine pretty high in neutral, I felt this mild grinding coming from someplace underneath... Does anyone know what this might be? Is this normal? My last car was an Acura RSX 6-speed and the engine was pretty smooth at high revs... no grinding. I just don't want any surprises when mine comes in. Thanks

 

grinding no, vibrating yes
