righto then

That makes sense about the valve overlap and wasting fuel, but doesent the valve overlap lessen as the motor revs more?
hence the smoother running?

So at idle, sure there would be fuel wastage, but whent he motor revs harder, wouldnt the more aggresive cam be of benifit?

The economy isnot a big deal since its not the daily driver, but sure I dont want to be wasting volums of fuel for nothing more than a sound.

Also, done some more reading. A centrifugual type charger is really only a turbo that is belt driven. So this would be the easiest option, and probally the cheapest since they are more common (corrolla, commodore both used them i think)
