I don't completely agree with the comments about displacement.
When you apply boost to diesels you are in a sense increasing the displacement. So while at 0 gauged psi, you might have more displacement in a BBC, when you spool that turbo up to 15psi or more you are doubling the displacement so now your comparing a 7.4 BBC to a 11.6 CTD.
It sounds really obvious and I'm sure a lot of people understand that but I just wanted to out it in writing so we are all clear. Many people jeep going back to the whole there's no replacement for displacement argument but it all seriousness the CTD is pushing out more exhaust gas than the larger gas competition so therefore it has more displacement.
All the peak up numbers and tq numbers were made at peak boost or max displacement.
