it also is going to depend on your driving style and drive pattern. how much and how fast you rev the engine will affect how it responds. city driving vs highway driving is also going to respond differently.

It would be interesting to try on my truck (2.4l 4 cyl), stock is 26lbs not including the pressure plate. I have seen them as low as 12 lbs. I've also seen one place that advertises taking 10 lbs off but leaving most of the weight around the outside edge. Interestingly enough stock for my cressida is only ~18lbs with a 3l I6. I'm guessing it's because the I6 is inherently smoother than the I4.
