I will drive mine until the motor gives out and then quietly drop in a 3.8L X51. As it is I can still get into plenty of trouble with 201hp.
Your thoughts are intuitive and make sense. Mine aren’t & don’t, I guess. But, are you saying Nissan and Hondas, etc. have much lower hp per liter and with lots of tweaking would max out at 80 hp per liter too? Or (god forbid), are you saying they’re stronger motors?

What do you see as the negative effect of more cylinder pressure, rods, rod bearings, the crank? What’s going to break as opposed to wear out faster?

I’ve heard lot’s of anecdotal stuff about them blowing up to, never met someone who had that experience though. Whereas I’ve also heard and met many who drove/drive them uneventfully for years, probably much harder & more often than I do.

Rationally I agree & understand most of what you say but dam it’s fun. can’t see someone going back even if thy knew better.

Regards, PK
