Noticed this a few times, always in the low-6000 rpm rev range.
Basically as the title says, while expecting lifespan to go up by setting the redline lower, sometimes it goes down. Changing nothing else, I would get better lifespan out of an engine spinning 6300ish revs than and engine spinning 5900-6000.
If there is another factor at play in this, I’d be interested in knowing, since more-revs = better lifespan seems counter-intuitive.
Either way, not really a big deal, just thought I’d give you guys a heads up on it. Great game, I’ve been having more fun than I should be making small V8’s, and attempting to use overhead cams in eras where they really don’t belong. Looking forward to the boost update.
I think this is because the game looks at the torque curve (or some average figure or something.) so when you remove the few hundred rpm the game thinks the torque curve is worse. If this theory is correct this should happen at some cam values but not others.
Yeah, I’ll try to put one together tonight or tomorrow. Only happened with V8’s, I’ll see how to replicate it once I figure out how to export engine configurations.
How do you export an engine created in scenario mode? The one I experienced this with was my “Propelling Luxury” engine (Gold 1150pts, 7.0L DOHC 32 valve crossplane V8 with single point EFI. I re-created its specs in sandbox to save and export it. To experience the glitch, run the motor the way it is (redline at 6400, best for the scenario I built it for), drop it to 6300 and lifespan goes up slightly (as it should). Drop it to 6200 and the lifespan goes down. It will continue to go down until somewhere around 5700 or 5800 revs.
On a side note, I think the year where MPFI becomes available is a bit late. Being a honda geek, I know for a fact there were multiple cars (such as every accord sold in north america) with MPFI in 1990. Some sooner than that, the original B16A had MPFI and VTEC, which kicked in (yo!) in 1989. Then again, they were a bit ahead of the curve. 7.0L XP 32 Valve DOHCRev0.xml (1.76 KB)
As has been pointed out before, technology year is NOT invention year. It merely represents when the technology could be considered sort of mainstream. A race engine might well be using tech 15+ years in advance of the current date.
