hp (DIN)
DIN horsepower is the power measured according to the German standard DIN 70020. It is measured at the flywheel, and is in practical terms equivalent to the SAE net figure. However, be aware that DIN "horsepower" is often expressed in metric (Pferdestärke) rather than mechanical horsepower.
hp (ECE)
ECE R24 is another standard for measuring net horsepower. It is quite similar to the DIN 70020 standard, but the requirement for connecting an engine's fan during testing varies. ECE is seen as slightly more liberal than DIN, and ECE figures tend to be slightly higher than DIN. John Deere is one strong adherent to ECE testing.
9768-EC
I may well be wrong but I also thought that HSV had a 6250 rpm limiter compared to the Holden 6000. My tuner changed mine accordingly, not that I climb that high.
Supposedly there is 36kws difference between the 6.2 Holden and the NA HSV.
The VF2 displayed redline at 6k but it does rev to 6250 aswell.
VF2 redline is 6600rpm.
LS3 redline is 6600 rpm.
