I got a bit of a wine too, but I havnt been really noticing it, maybe its either i almost finished with break in or I just got used to it haha. I have no idea what its from tho...

gadget · 05-30-2008, 11:32 AM

air intake from the opening in the hood-- i think its normal but not sure...

rvacha · 05-30-2008, 11:57 AM

Yep, I've got a cool whine as well. I figure its the belt or VANOS, but I could be very, very wrong. Anybody know for sure?

Dunno. Mine makes all kinds of interesting noises. Never owned a car that had so many different engine tones.

MDCTFTW · 05-30-2008, 12:33 PM

Are you sure your woman isn't in the trunk? (joke taken from someone else on here)

I get a whine also ... not sure what it is. I'm a little paranoid about the sound my car makes at idle though. I get some sort of gurgle besides the normal engine noise, but only at idle. Anyone?

Mx3 · 05-30-2008, 12:35 PM

Mine has the "whine" as well. I think this is normal. It's subtle and sounds good

nusevad · 05-30-2008, 12:51 PM

I dont mind the whine as long as its normal. Sounds like a supercharger haha

The outermost camshafts are gear driven from the inside camshafts which are chain driven from the crank.

The cheaper alternative is to use a belt but they stretch under high loads.

Anything gear driven will produce a whine of some sort.

I concur, to anyone what knowledge of both the Lotus Twin-cam and the Cosworth BDA engines will know exactly what you mean by this.

ah ... thanks guys ... well it sure does make this car feel like a highly tuned precision machine ...

... loving the car more and more

lucid · 05-30-2008, 03:35 PM

Yeah, I have that, too. I thought it was coming from the differential though.

ScotyH · 05-30-2008, 08:52 PM

Yup, the diff noise is there too.

Seems loudest at about 60-70km/hr

dbacon · 05-31-2008, 01:07 PM

The whine on my 6MT car was more prominent after the first service. I like it...very subtle.
