GR Yaris Misha just gave us all a present!

[Duke]

I know that the the hardest I've ever felt my car has worked would be in the Alps, not on the track.

A lap of the Nürburgring is <10 minutes and most will only do one, maybe two, then go and chill out for a bit. On a shorter track there will usually be sessions of about 20 minutes, but if it's an open track then I guess there is a temptation is to stay out for more laps.

In the mountains though you can easily be 'on it' for 30+ minutes at a time, with the elevation changes being much more severe than even the Nürburgring so even if you aren't ultimately driving as hard as you might be on a track, it's as hard or harder on the brakes and engine, for longer.

I guess what you’ll get on track which you won’t on the road though is the kind of sustained lateral loads which are likely to lead to oil starvation.

400km after tuning , I almost don't believe it.

Ironically perhaps, mountains can be a huge load for 'normal' cars, while relatively powerful cars have an easier time. I wasn't there but I have a hard time imagining that 30min+ was wide open throttle to redline at every moment you weren't braking or taking a bend. If so, either very lucky with traffic and speed limits, or you literally have hundreds of hairpin bends with very short straights. Then it's worse for the Dutch cars running up the caravan....

If someone commutes their GRY in the Alps, in summer, and has no traffic or speed limits, and their name is Delecour or something similar, for sure it can be as bad as proper full on track driving absolutely. Because here we're talking about cars that basically are only ran at the ring, for 10,000+km, of which the majority was wide open throttle and upshift at or near redline... Not just the 1-2 lap visit...

Anyway. En engine has a finite number or revolutions it can make before breaking, and that number is significantly reduced with heat and (excessive) load...

maybe 200hp per ltr is good limit in terms of reliable full monty power, Unless rebuild internals. please prove othervise.
its quite much anyways for such a small motor.

It's not black and white, how this 200hp/l is achieved also plays a big role.

Big difference if it's just a stage 1 remap, or if that number is achieved through better flowing and heat load reducing hardware which could just be possible on stock mapping. Then the actual thermal load on engine is the same or even less then stock, but power is up a good bit.

Running that hard and much at the ring, that tune (370hp?) was a bit ambitious...

The speeds that car carries at the ring are not those of a 370 bhp Yaris, that is for sure…they’re almost close to stock power.

My sophisticated PhD research on YouTube concluded that we are looking at 2 different GR Yaris’s.

There’s the grey one in front, the driver is “Tom” (later he’s the passenger with Misha), supposedly with 370+, and the now blown up engine (but my research didn’t find the respective source for that) @Hini ?

and the white one behind with a guy named Miguel Almeida, with his YT Channel Great Motors, 280hp and a very heavy passenger…

(“Saving Weight” just got a whole new meaning…)

Yep, those are the ones we're talking about. Grey one did pass Misha like 4min earlier then the white one and they started together on the same lap. Grey on seemed to pull away pretty well out of the caroussel from a supposedly much higher power again E46 M3... So I did expect some extra power in the grey one and, honestly, was already thinking when is it gonna blow...
