Engine Blow-Up. Is Qualifying Engine Wear Tied With The Race?engine blow-up

No idea what caused the blow-up or if it was random.
Lots of things are possible speedshifting Lotus at 9300rpm.
My favorites are camshaft, ignition, and header.
Probably specific driver errors that are associated with each.
Too much load on the engine will mash up and flatten cam lobes in real life and probably crush some bearings, bend a valve stem or leave one in the cylinder too long.
Happens in an instant at the threshold of metal fatigue.
That's why hill climbs are so challenging...its all about the engine.
For instance, shifting too early or shifting to a too long gear while ascending the hill between T5 and the Corvette Bridge, or up Thunder Valley, or up the Main Straight, might or would do that.

I tuned carefuly all five gears, with special attention to 2nd and 3rd gear, to avoid reaching red line in those points of the track that you refer. That's why I don't understand what happened. If there's no tie in the damage model between qualifying and race, then I must conclude that it was a random blow-up.
Getting tired of this game again, because of this kind of things. I think it's time to stop again another 5 years...

Engine and suspension failures were quite normal.
GPL has the reliability coded in each car, so if you drive a Lotus or Eagle it will happen more often than in a Honda or Brabham...

SV3000, in fact I did a very good and quick start in this race (my best one so far). If that is related, it's a very, very silly thing... Thanks for the comment.

My experience has been it is a very rare event although used to be very good at it, especially when shifting up while passing a car out of its slipstream. Bad idea. Always shift first when well behind and use higher gear to accelerate while approaching the leading car. JMO.
Shifting at 9300 is only a fraction below the spec 9400 redline...a moments loss of traction could over-rev beyond any reasonable limit in about one millisecond probably.
The real Lotus 49 was fitted with as I understand a sort of crude maybe first time ever rev-limiter that kept RPMs below 9K to prevent the engine from blowing up if shifted near its tech perfect redline.
There is no torque worth using past 9Krpm anyway.
With you tho, and against all prudence, routinely shift when it seems the valve train is just at its max rpm happy point, where torque really falls off and there is pretty much no load on my fantasy motor.
Better get that right, based on experience.
Very very rarely blow an engine in advanced mode, and its usually in my view my own fault.
Really would just go with it being random unless it happens more often.
Or it could be on-line related? No idea at all.
iGOR went down on the 6th?

this happened 2x in the last UKGPL season to me
66s at Oulton I had a big lead when my engine got sour 2 laps to go and I was caught 400m before the finish line...

These occasion have been very rare luckily.

Yes, John, iGOR was down and the race was done through VROC (this league runs on iGOR by default). I also wandered if it was something on-line related, as I tested the setup before for many many laps in a far more agressive way without blowing the engine.
Millennium, I also have seen very strange physics, online only, like the ones you describe. Another strange one that happened to me in my short 16 races experience was three races before this one, in Enna Pergusa track: some players had a simultaneous screenfreeze and at the exactly same moment my car was pulled to the interior of the corner and was impossible to get it stoped; the game didn't respond to any control, and I had to shut down GPL in task manager...
