Questions regarding high RPM engine sounds when shifting?
Hello to all. I hav an 05 sedan 6MT sedab. When shifting gears at or above 5000 RPM, i heard the engine wanting to keep on reving when I depress the clutch with the foot off the accelerator. The engine seems to keep on acclerating even though my foot is off the gas. I can only hear it when shifting above 5000 RPM,l and not below. Is this normal? Does it have anything to do with the electronic throttle that our cars have insead of a cable?

This is normal in hard shifting - I bet your timing is a bit off between the clutch and gas. Nothing noticeable in performance, just simply that the car's engine is still responding to your throttle signal when in fact you have already pushed the clutch in to dis-engage and shift. The RPM will shoot upward when the engine is not under heavy load with the same pressure on the pedal.

As a 6mt driver, I agree 100%

Compared to other manual tranny cars I've had, the G does seem to hold onto it's revs longer... but they don't climb on their own.
It seems I remember reading that the ECU gives it a little gas even when you lift off from the pedal to help with emissions, causing the RPMs to fall off at a slower rate than you may be used to.

I am very close to my 1200 mile mark, so I am starting to explore some higher rpm fun. I have noticed a distinct growl from the engine between gears when shifting (5500+ rpm). My first thought was that my foot must have still been into the gas, so my next shift I made a point of taking my foot all the way off the pedal. Same noise.
This isn't my first manual (Mustang Cobra, SVT Contour, Prelude), so I'd like to think that it not my shifting.
If this noise is normal, so be it. It does sound pretty menacing.
