Kenneth: Ok, then I think I understand what you mean.
Well, the thing is that if you calculate 25Nm at 8500rpm it should be equal to 30hp. If that was true it would still “want” to accelerate, but instead it “stops” at 100km/h. This also means that the 25Nm is not really 25Nm. I would say that it should be closer to 18Nm (or 22hp). Ofcourse this is still a guess, we should have that in mind, but I would be surprised if it really did put out 30hp.
So I guess that you will then say: -The 30hp is lower down in the rpm scale and not as high as 8500rpm. (Correct me if you think otherwize)
-Yes, that might be the case, but if we look at the Nm curve which can be found in the Sevcon setting it is more or less 30hp all the way from 2115rpm (100Nm) and up to 9000rpm where it delivers 23,7Nm. So if the power is “wrong” at 8500rpm, what do you think indicates that it delivers 30hp (or at least more power) lower down in the rpm scale?
According to me it is more likely that the Nm value it is wrong all the way from low to high rpm (maybe approx 30% lower than what is indicated). Byt hey, don’t get me wrong, this is still an assumption from my side and I really want to underlige that I’m open for other thoughts as well, as long as they are possible to understand…
And as I have said before: the powerbox is still a really nice thing to have even if it does not put out 30hp!
