Talking Weighed my MY99 STi RA today .....

... and it is 1280 kg - no driver, half a tank of fuel and the spare wheel.

It's the V Ltd edition, so it has AC and leccy windows.

So does that confirm what the manufacturers data is for the car. How much lighter is than a stock my99?

I've got my WRX01 down to 1400kg with a full tank of fuel (or 1350kg when below a 1/4)

I'm not sure, I remember seeing a list of Scoobs and their weights but I'll be fooked if I remember where. I'm sure both the Type R and the RA are supposed to be about 1240/50 something like that. As for weight difference between a standard MY99 I don't think it's much, no more than 40 kilos.

It is useful to know the real weight of the car, particularly when using software like Delta Dash to calculate your power curves etc.

1280kg's sounds high

Though the sti5 standard car was suposed to be 1280kg - so if its more that would explain why my car is slower!!

I tend to agree, but I think it probably depends on how the manafacturers weigh them for the specs. I'm sure if you drain the fuel, coolant, oil, remove the spare wheel, jack and other bits you could probably drop another 40/50 kg off it.

Yep the manufacturers weights are dry, so no fluids but i believe the spare and jacks etc are in there!

Full tank of fuel = 55kg

engine oil will be around 10kg

gearbox oil around 6kg

coolant another 2-3kg

So it all adds up and makes a bit of difference

from what i remember, the book says

my99 1280kg
01wrx 1380kg
01sti 1480kg

Think a 60 litre tank is more like 40kg from the density figures I looked up. 1235kg for the MY99/00 UK saloons were without aircon, whereas 1270 is listed for STi/P1 both with aircon, but of course ally bonnets etc, so presumably the aircon is at least 35kg.

I weighed my MY00 UK/Euro spec turbo with myself in the car and a quarter tank of fuel and it weighed 1370kg. Take off my 88kg and you're left with 1282kg. It has airco as well.

Cheers,

George.

1litre of water weighs 1kg (give or take a nanogram) so i don't think that petrol would be that different in weight

Engine takes 4.5litres of oil, i would think oil to be slightly heavier so maybe 5kg

Sorry for not being so precise pavlo they were only rough figures that i quoted

Oil is famous for floating on water, so it is lighter actually

http://www.simetric.co.uk/si_liquids.htm

On this list, vehicle gasoline is about 73.7% the density of water, so 44kg for a 60 litre tank.

Oil is about 90% of the density of water, so about 4kg.

We've saved 20kg for you Scott on just the petrol and engine oil, so the errors do add up.

I know you are right John but that seems quite silly - water rinses off the arm so much better than 'thin' 20/50!
