You mean why the non rev-up DE is rated for more wtq than the rev-up and HR, right? In the case of the revup DE, though… the non-revup IS more torquey… they both go by the older SAE standard. Just the HR falls under the new standard.
Yes, but your opinions are based on nothing more than your own hunch, and no experience. I can accept that that’s your opinion, but it doesn’t mean anything (no offense intended with that statement). R&D is always expensive for new engines, but it still gets done. That’s nothing new.
