Induction Noise Change At Top Of Rev Range

kpkpkp · 04-04-2010, 10:58 PM

I have noticed that my induction noise seems to get a fair bit deeper as it hits the last 3-400 rpm of the rev range before the led shift lights light up.

Is this correct or do I have an issue - the car pulls through the revs fine.

I'm pretty sure mine does this also. Normal i would think.

Sounds normal to me mate.

It's normal, it's just where the engine takes on more load for want of a better way of describing it I think

I'm also pretty sure mine does it, I have the flap installed and working, flap opens at 3k in sport and 6.2k in 'normal' mode I think doesn't it?

Later in Sport I would have though, 3400 or 4000 even

kpkpkp · 05-04-2010, 10:13 PM

What difference does removing the flap make?

and about 7000rpm with SPORT button off
