How do you work out the Brake HorsePower (BPM) of a motor vehicle like a car , van , motorbike , lorry etc ?
Answers:
As the other guy said find a rolling road and have it tested but if you are of a nervous disposition about your vehicle go 4 a walk when they are testing it cos it don,t sound or look pretty and also be prepared 2 be a bit disappointed about the results its good if its better than u think but on the other hand if it is not as pokey as u think it is it hurts especially if u have put a lot of cash into it I once had a Suzuki gsx 1100 back in about 1978 got lots of parts fitted you know the usual kit nice 4 into 1 exhaust system etc.etc and after spending a good few quid on it took it up 2 Santa pod on a run what u brung day and got my bottom well kicked , But luckily there was a mobile dyno testing firm and after my first 2 runs after getting caned by a tuned LC 350 and a 250 gamma Suzuki I decided some thing was maybe not well with the world ! so I managed 2 get a spare slot in the test wagon and to my horror found it was actually 25 bhp down on standard I was given a lovely print out showing mid range power loss mind u losing 2 a tuned 2 the balls LC350 is no disgrace the gamma was also cool so no complaints fair enough lads you whipped me !!!!!!!!!!.
