Can we please put the old engine/new engine argument to bed.
Engines are stripped and rebuilt on an hour or cycle schedule.
An "old" engine rebuilt properly is a sweet thing to watch as it sits on the wing next to it's "more tired" counterparts, burn,egt,N1 all comfortably below the others. In the end it is down to where you get your rebuilds done. I have had rebuilds done at Haeco / Taeco, RR and Luftansa Technic (sp?) and can can attest that LT were by far the tightest rebuilds by a long shot.
MIC, great satire.
As to the twin/quad debate, I'll take 4 over the pole anyday.
Ben, keep it factual.
AJ, bye.
