With that said, a mini at 650 kilos with someone in it ruins it's power to weight ratio as well!

Anyone care to do a torque to weight ratio thread?

power to weight ratios are all well & good,,,But!!!!!!!!!!

just think for a minute about a train,,,i don`t know how much they weigh,,,or how much power they have, so lets say (for EG:s sake) that they weight 5000kgs & have 5000hp,,,(however you`d like to calculate it in imperial or metric,,,whatever, it`s for EG:s sake not mine )

so the train has power to weight of 1:1

well the dam thing weighs 5000kgs so wether it`s got 5000hp or 50,000 hp,,,the average go-kart with 10hp & 80kgs will beat it in a drag race anyways, right???

so it`s all well & good sorting power to weight ratios,,, but if a fat ass tank of an old sh!tbox monaro weighs 1200kgs & has 300hp,,,my sh!tbox mini is still gonna flog it , simply cause it`s actually lighter

it`s a bit like that old crappy 125cc motorbike that weighs 150kgs & has 25hp,,,it`ll still flog my mini in a drag, the dam thing will dart off in an instant while we`re still trying to get bloody traction,,,hee hee,,,the dam fat arse train has heaps of traction but still can`t beat my mini tho

are well,,,another bourbon & i`ll be happy

dribble over

You should put your heart & soul into everything you do.

all i know was on saturday night i was pulling away from the commodore next to me with him reading :SHOCK all over his face

And thats with my gf in the car too.... Amazing what a dyno can do for performace....

So... how many HP you got now, on whose dyno??

DrMini- 1970 wasaMatic 1360, Mk1S crank, 86.6HP (ATW) =~125 @ crank, 45 Dellorto (38 chokes), RE282 sprint cam, 1.5 rockers, 11.0:1 C/R.

So help me out here.
Low'n blown is expected to tip the scales at 625kg, with kevlar seats, molly cage, and everything drilled and lightened. Power at the crank is 204hp on Waggot dyno. So 625x2.2 = 1375. Then 204/1375 =0.148
Is this right or have I done something wrong??????

I have a 50hp NOS kit to go on it after the car has been DMT approved. Allowing for losses in drive etc allowing for around 230hp at the fly. That gives me???????

Gees those are some very interesting figures.

I get 65hp(flywheel)/700kg = 0.042

not bad.

Brad that is one impresive car. LOVE IT

greg you're just showin off now haha

230HP/1375lbs = 0.167
very nice indeed

MiniMan: i follow what you're saying, so it leads to the question:

What does
1) Power
2) Power to Weight Ratio
mean,

in terms of:
1) Acceleration
2) Torque
3) Top speed

?

Sounds like you need to race one of these things to see which one actually goes faster. Guess you should consider gearing too, I've seen little motorbikes that go like the power of piss up to 100kph, and that's all its got. That makes me feel special, my Mini goes faster than 100 Well, it did. Now it doesn't go at all

.... the need to wear brown undies while driving...

Lets face it,
at the end of the day they are front wheel drive and if you cant get the power down it doesnt matter whether you have 100hp or 1000hp, there is a limit to what you can get out of the chassis. Does make me wonder how the hell QIK850 ran a 12.6 though at Willowbank.

3 words
moment of inertia

Yep thats exactly right. forget the 20" chromies. And with the big 5000hp train it has a sh!t load of moment of inertia in all those massive iron wheels. For those who dont know, moment of inertia is the rotational momentum, or the resistance to angular acceleration. Its also the reason why we lighten all the internals etc. Mini's would probably have an advantage over rwd because they dont have a heavy prop shaft between the 'box and dif... then again they have trouble getting power to the ground gets very compliacted

Still, 3 words:

What the f*ck?

you know, me and science, we just don't mix

lamen terms.. heavy parts take a lot of energy to get moving

thats why most hot sixes will out drag a big block V8 with double the power
