Clint says 60 hours.
This is the only response I got for the F600 engine when I was taking the survey.
I put 53 hours in my spreadsheet because that's exactly two years in my scenario.
I just updated the
spreadsheet to say 60 hours. The new operational cost per weekend for F600 is now $987, or $123 per session.
If you would like to provide another opinion on these two numbers for F600, I'd be glad to work that into the spreadsheet.
Engine rebuild or replace, $:
2,500
Engine competitive hours:
60
The engine scenario is: you've got an engine that's capable of winning a majors (or even the Run-offs) with the right driver, 1. for how many hours does it continue to be able to win a majors race, and 2. when it no longer can win a majors, what does it cost to get back to majors-winning engine (rebuild or replace)?
Sorry for the detour, but it seems important to know engine costs for this new car (600 vs. 1000).
In any case, I think it's safe to say that a 1000cc shifted at 7500 RPM will last a lot longer than a 600cc shifted at 15,000 RPM.
Of course, torque is another issue--50 vs. 80 ft-lbs.
Weight is similar, cost is a few hundred more for the 1000cc engine.
