maybe we'll meet this 16 second wonder one day with our slow v8's.
Your argument about v8's being inefficient is getting you nowhere dude. Your ability to grasp math, common sense, and knowing when you said something stupid is sorely lacking. Displacement is not meant to make up for inefficiency. That's why an ls6 makes more HP stock than most of your ricer 'champions' (an SVT makes even more HP per liter, with not much boost).
If you look at most stock japanese cars (naturally aspirated) you will see that they're either right around the v8's, or less.
There is a reason japanese, german, italian, and american manufacturers use higher displacement v8's for high performance applications my friend, and it's not because they're too lazy to get the desired amount of HP out of a 4cyl engine.
