Hi, I'm wondering if my supercharger is defective because when I need it most for overtaking it seems to be very lacklustre.
A typical situation is when I'm stuck on a country road behind a Sunday driver. I'm in 4th gear (manual transmission) doing 40 mph at about 2300 RPM, and when it's time to overtake I'm really not getting the boost I want, it feels very sluggish, and makes for a very slow overtaking manouvre.
For contrast - When I'm in 3rd gear at 30mph at about 2200RPM the car surges nicely forward when I give it some throttle and it has that nice supercharger tone. Also when I'm in 5th gear above 50 MPH and I give it some throttle, again the car surges nicely forward and I hear that beautiful supercharger tone.
But at 40 MPH in 4th the supercharger performance is unimpressive and even the noise doesn't sound right; I don't know how to describe it but it just sounds a bit flappy. It doesn't even sound like a supercharger.
I know I can just downshift to 3rd for overtaking but I'd prefer it if the supercharger would just do the work for me, and 40MPH in 4th is always the exact scenario I need it, yet it seems to be the exact scenario where it doesn't want to perform.
So, my question is - is this par for the course with the SLK R170? Or does it sound like the supercharger is somehow defective?
Thanks:crying:
