Windage control for sure is an issue on that engine in the video, but also makes me wonder if there is so much oil in that engine, where does it all accumulate for the sump to empty? top end? I've heard some people with later commodores have this oil pressure loss on braking but I personally never s...

Those are for the US FWD ecotecs, they actually have the sump part in the middle, somewhat to the rear of the engine unlike ours with it right up front. So the tray might not clear the limited space at the rear of our sumps and there is the whole pickup tube location situation too. Might be handy fo...

Came across this relevant video, the guy in it is really goofy but some interesting and surprising results with the oil windage.

https://www.youtube.com/watch?v=Ow4jldkybEY The engineering at NASA and all their associated contractors is truly like alien technology compared to what we have here in the public. These tools would be to ensure characterised and known reliability for all their spacecraft wiring which ensure the be...

https://youtu.be/DJDDlAkyHfc?si=zVNA1SwCVrfFkYiv Something you'd considered Gareth? I thought that was very interesting and is something I have thought about before as good ABS is very nice to have when you push your braking hard. EDIT: Can't get the youtube embed to work. Antus, is there a way to g...

Probably a oscillation/resonance with the leaf spring rear end. I know every single ute/wagon both Ford and Holden that used leaf springs axle tramp something shocking and worse so when sticky tyres were used. One of my work colleagues from years ago had a Boss Ford BF ute with Nitto tyres, pulling ...

I wonder if your timing is too far advanced, and the humidity plus reduced oxygen is bringing your timing closer to optimal? Perfectly valid logic which I also glanced over but since they have been tuned on the dyno, they are on the optimal timing. VR MBT at WOT peaks at 27, nearly 28 deg with 9:1 ...

I found this. Still suggests a reduction with high humidity, but there is a decrease in internal EGR and intake pressures also increase with humidity, but peak pressure of combustion and it's timing significantly slows down and retards. These engines are quite knock limited, so perhaps the high humi...

All valid points, but all of these other's have mentioned are counter to what physics are saying to the best of my understanding. The point on combustion speed might be the best explanation, but it doesn't make sense if the engine is already tuned at MBT in more typical conditions. The cooling effec...

As per title, why and how can a muggy warm and very humid day cause a significant uplift in performance above baseline, more so than cold winter days? This is something I instantly noticed during the last year or two over summer and the warmer months as we have had 2 years of wet and warm summers wh...
