Nothing I've read here has been informative as to why. All I'm seeing is that if you want to show how big your "wallet" is, it's the part to buy. A $20 hooker in a $1000 dress is still the same beast. I see a few guys here that assume that if you don't own one you are just running cheap junk. I assure you we didn't build a n/a 864 hp pump gas engine on cheap parts. The parts were selected very carefully, but not on the premises that just because it cost more, that it must be the best part. That's the way the government and unions work, and we don't cotton to that mindset.
