still trying to find out what hp kw, whatever it takes to run a box and diff??
byron said 20% but i need to be more specific! i need to answer a question in another forum,
eg, they measure the output at the rear wheels?
rwkw!! so what would be the kw at the engine??
will the difference tell me what the gbox and diff is taking to turn it?
it has been written in here, but i cant find it? cant remember the figures? or post
i seem to remeber a t400 takes more kw/hp to run than say a 4 speed?
can someone help without too much jargon,
cheers
bcb
ptpro
some men see things as they are, and ask "why"
I dream of things that never were, and say, "bloody ripper idea mate, lets try it",!! |
more than basketcase than a bear!
DOH!!! |

Ah! I get it now. You want a specific answer to a non-specific question?

Mate there is no specific formula. Like you said a th400 will sap more power than a 4 speed manual. A 9" diff will sap more than a Borg Warner. Dont forget too that tyres and uni joints will also take (small amounts of) power away as they all have fric Edited by user Friday, 4 July 2008 12:50:29 AM(UTC)

Mr Bear its really easy......
...but at the same time quite hard.....
of course you can work out how much power is needed....but..
...go to...or ring up would be better ....latrobe university engineering department......and they will give you some guid

Using the calculations supplied in your other thread on this topic,
it would take approx .75hp - 1hp to turn your assembly WITH NO LOAD, e.g, with wheels off the ground.
AND using a manual gearbox.

The answer ist a fixed percentage...but its not linear either.
If I had a 100 hp 149 engine in an eh with aussie 4 and banjo...then by applying the 30% idea...I have 70 hp at the treads.
But if I flick the 149 and fit a turbo 202 and now have 300

Hi Bear,
Heaps of engineering formula's and tearing out a bit of hair may be needed. But (and I have not tried this)
Maybe you could use the manufacturers spec's for flywheel Hp/Kw verses the spec's from a dyno shop for the the rear wheel Hp/Kw,

thanks all oil37,fast eh,etc,,,[would not have bean fasterer than my yellow gold eh prem wagon? in 1974!!! by the by.]
gives me an idea,
clearly box and diffs although varying depending which ones they are, use a fair amount of hp/kw, just to turn them |

yeah casper,
what a waste of money?
$1>2 fill up,, same as petrol!! @20k,s
some of the proffesional elec cars are reasonably good range, and good power.
but these home made numbers are a laugh!
the ev site i am on, they go on with so much jargon, |
