528 gallon tank???
speedyxjs - 17/4/08 at 07:38 AM

Im trying to design my tank but i think im calculating it wrong.
The dimensions are 100cm x 30cm x 80cm which i work out to be 2.4 metres cubed. I used an online converter which says the volume is 528 uk gallons. Surley this isnt right?

oh that’s right enough, the UK gallon is about the size of a sugar cube

It works at at 0.24 cubic metres or 240 litres.
Thats a pretty big tank!


Paul TigerB6 - 17/4/08 at 07:46 AM

quick calc says 240L - bit less for internal dimensions. So at current prices that would cost around £260 to fill (and contain around 240kg of fuel). You might want to go a little smaller mate!!

You've got the decimal place in the wrong place.

Cubic centimeter is the 3 dims multiplied i.e. 100x30x80 = 240000cc

Convert that into UK Gallons and that's 52.7926 or 240 litres.

Edit to say "holy crap, look at all those replies whilst I was typing!"

240 litres which is equivalent to 52.4 UK galls.

Big tank, what are you running a jet engine ??


speedyxjs - 17/4/08 at 07:52 AM

No jag engine so close enough
I just wanted a rough idea but at least now i know i can go a bit smaller
I might go for about 80 litres. These jag engines arnt the most economical


Humbug - 17/4/08 at 07:54 AM

I know you are using a Jag engine, but even so 240 litres seems a bit on the big side


Paul TigerB6 - 17/4/08 at 08:14 AM

240L of fuel to fill it - that would be like karting around 4 bike engines or half a BEC!!


graememk - 17/4/08 at 08:30 AM

i think i currently have the biggest tank at 40lts, 240 is just silly


speedyxjs - 17/4/08 at 08:34 AM

40 litres!!! I definatley want bigger than that
Because my engine is so heavy i want a fairly big tank to compensate a bit for that. Also i understand that alot of locostbuilders end up stopping every 100 or so miles for fill ups.
I think 70 - 80 litres will be what i go for

i only just got through the brake test and axle weights at sva due to the weight of my tank full.


blakep82 - 17/4/08 at 09:35 AM

think you may have confused your cubic meters with cubic centimeters

Build your own sports car.

And fill it up for £250


mcerd1 - 17/4/08 at 12:10 PM

what they all said ^^^

what size tanks do the jags normally have ???


1 gal (UK/ imperial) = 4.564 l
2 gal (US) = 3.785 l


JohnN - 17/4/08 at 12:41 PM

Are you sure 1m x 0.8m x 0.3m, that's either unfeasibly tall, or unfeasibly big in plan, neither would fit in the rear space of a seven.

Sure it isn't 0.1m x 0.8m x 0.3m

Which is 0.024m3, ie 24 litres? ie 5.2 gallons?

Cruising... I get about 300 miles on my 50litre tank....blatting....a lot less...

2 litre zetec with Gixxer 750 Throttle Bodies


awinter - 17/4/08 at 01:11 PM

my 4957cc V8 928 weighs 1650kilos and has an 80litre tank, cruising at 70mph it will do 400 miles on a tank.

The sylva striker has a 900cc bike engine in it and a 24litre tank and will do 170 miles on a tank @ 70mph

Fitting a 80l tank to your car is overkill. 40l max.

Yes if you blat it mpg is crap but take a jerry can or 2 it'll be better in the long term.

I went for twin 25L tanks to get better balance while acheiving a realistic range - about 300 miles of cruising with my V6.

Watch out for sloshing too - it can really throw some weight around and upset things if not adequately baffled. You could also consider foam filling.

80 litres and lasts about 3-400 miles.
My chassis isnt a standard locost chassis. Its quite a bit bigger
Maybe 80 litres is too much
I want more than 40 litres because that would have about half the range of my tin top.

Just a thought but have you ever driven over 200 miles in a 7 (let alone 400 ) without stopping???? It's not quite the same thing as sitting in a Jag and doing it and I think you'll find you wont fancy doing it that often.........

good point Didnt think of that


JohnN - 17/4/08 at 06:06 PM

"JohnN - My chassis isnt a standard locost chassis. Its quite a bit bigger"

What is the height of your tank then? Your chassis doesn't have a rear at the moment from your archive photos, but it looks like it'll need a huge one then. Either 1m or 0.8m is way higher than the vertical space available above the differential. have you actually made this tank(er) yet then?


speedyxjs - 18/4/08 at 06:48 AM

No i havnt made the tank. My plan is to have it at the rear of the car like in the boo and have a slightly bigger boot to make it a bit more practicle


RazMan - 18/4/08 at 09:52 AM

I think I might have found one about the size you want Speedy



any good?


speedyxjs - 20/4/08 at 07:12 PM

^^^
HOW BIG IS THAT!!!???
