Fuel capacity?

[Stu]

What about the new spec 'EFRA' pipes? Will my Jammin be OK?

[showtime]

the "new" spec pipes aren't freely available yet as such and a lot of the foreign drivers run to different rules etc so there is no hard ruling on pipes
noise isn't really an issue at the college as the nearest neighbours are a long way away

to quote LewisDXR when asked about pipes for the last meeting "as long as it doesn't sound like an ASBO'd up Subaru Impreza you should be OK"

any of the pipes from the 2007 list will be fine

as a note the BRCA are allowing 2007 spec pipes at Nationals this year anyway

yes the 3 chamber ones..efra marked 20xx

Hey guys....

I've measured the capacity of Northy's tank today, without the little plastic thing....

The tank capacity was 116cc's, now I think that if he keeps the fuel lines short then there'll be no problem

You need to measure it like said earlier in the thread Jim, give you summat to do tomorrow!

The internal diameter of the pipe is only 3mm or so?

surely you can work out how much pipe it will take to reach the limit.

if you cant let me know how much pipe you have, the diameter and the legal CC limit

Yeah, pay more attention next time

Okay this is late night maths and I don't have a calculator....

The wide fuel tubing has 2.5mm diameter = 0.25 cm

116 cc current, so with 125 limit you have 9 cc of fuel capacity left to spare.

CSA = pi x r^2 - 3.142 x 0.125^2 = 0.05 approx cm^2

9 / 0.05 = 180 cm of fuel tube

This can't be right..... can it? Anyone with a calculator or a brain seeing my mistake, as without a block in the tank as well.... seems wrong. Esp considering people were saying one with a block was close to the limit?

sounds about right

Be careful,if you're running a Kyo Inferno US Sports,as it's tank is a 150cc one fitted as standard.You'll need to change it for an MP777 one,as it's 125cc.

Your calc is correct - here is the easy way to do it http://www.handymath.com/cgi-bin/cir...i?submit=Entry

Change the values to cm and ccm - then input the figures. ( Height of liquid will be the diameter assuming the tube is full)
