One obvious reason might be because your autobox is changing gears quicker at lower revs? I was in Mizon's car (325Ci manual + cf cai) and i don't think it 'roared' as much as the one in the vid. instead of the meaty 'roar', my PiperX makes an inverted 'shoooosh' noise, very hard to explain in writing :cool:

The BMW Straight 6 has such a distinctive sound to it, love it! This video clip is what mine sounds like (http://lunchin.shackspace.com/GLI_GHL2.wmv) for comparison. Test driving another 330CI CS tomorrow though don't worry :)

Auto does tend to make the car sound more restrained as the gear changers are much more linear IMO?

With a steppy, you can't hold on to a gear long to hear the induction unless you put it in manual overdrive. It should sound very similar. You'll also noticed that the engine software on a steppy car won't allow the revs to pick up as quickly as that on a manual, so blipping the throttle has less effect of the induction roar.

However, the is the mother of all BMW induction noise (http://homepages.nildram.co.uk/~ephome1/CSLROAR.mp3) :D :D

the car does barf when I blip tho. 97k miles - think the engine has loosened up. Get loads of hissing low down, then barfing at 2k upwards. Throttle response even low down in the rev range is good.
