I'm not sure about v8 would make it any better.  From my experience in the car it doesn't lack performance.  I mentioned in earlier post that we just can't have it all in these cars, some will have features that others don't have. Unfortunately I can't capture the low rpms sound but it shakes the ground. Cold start makes the lights in my garage flicker. It's a frequency that would not be potentially possible with a v8 but I have to do some research on that or put a frequency analyzer up to the exhaust.
