Yes, with all the variances between dynosallanvw wrote:Car and driver should be around the 650 to 660kg. Are you going to get the calulator out Dave ?.
and the size of the actual horses(Shetland ponies in some cases!),
some basic maths is an easy way
to compare things on a level playing field.
Even with a poor start,
the MPH in most applications, is within a couple.
(unless you have a car problem).
So once you know the weight,
and have a MPH,
a HP number can be extrapolated,
which is very close to the numbers I have seen from a Superflow engine dyno.
If you have a dyno number already,
you can then determine,
suitable gear ratios,
or how much you can improve,
or even, if you are at the limit of you engine combination.
The numbers this calculation gives are much lower than a lot of people tell, especially in Europe,
but on a world stage,
if you are over 100hp per litre with my formula,
you are doing pretty well.
