Excuse itix that it looks like you wrote this.
My comments (besides what it says at the bottom) are sections that beginns with "Both the length" and "Explosion velcity" in the middle of the clip.

That's cool, I hope Proton will fund an ERC programme for MEM.

Coach 2: Fabia S2000 has 92,2 mm stroke. At 8500 rpm it means higher piston speed than F1 engines. Quite insane for an engine with steel rods I think. Polo WRC has only 73,8 mm stroke.

Dimvii: Thanks, I'm aware that there are many things to count with but still I find it interesting that there is no universal formula. Also we shall not forget that often the choice starts with stock configuration which isn't driven by same needs as racing use.

It's not really even playing fields to compare an NA unrestricted 2L motor to a 1.6L, inlet restricted restricted motor though. Airflow works completely differently for those two motors. Same with having things like anti-lag as well.

I think neither Mirek or I meant to compare DNA with turbo Munkvy, but the discussion revolves around whether short or long stroke provides the most torque.

I was not aware that NA Skoda had 92.2 mm Mirek, but it is so both Super 1600 and S 2000 rpm limit of 8500, or?
92,2mm * 8500 gives piston speed of about 26 m per sec. It is very fast and above what was previously thought was the limit for piston speed (25 m per sec).
But kitcar had not 8500 as limit, and if we take 93mm * and forexample 9,000 rpm, this will give the piston speed of about 28 m per sec.

Yes, 92,2 at 8500 rpm for Fabia S2000. That's why I mentioned it as it's unusual configuration for such type of engine.

I just checked Peugeot 306 Maxi and the sources say it had stroke 86 mm. I don't know the rpm limiter but most of the sources say the peak power was at 11000 rpm. 86 mm at 11000 rpm means the piston speed 31,5 m/s. Can it be real?

There was an interview with Bútor before Eger, and he said his Evo II Maxi was 300 Hp, with peak power at 8600/min, but the gearchange light flashes at 9700. I believe the factory/Evo III spec Maxis and the Xsaras had 311 Hp, but don't know the characteristics.
