best weight saving gainers
zxrlocost - 23/3/06 at 09:38 AM

morning morning whats the best weight saving gainers on our 7's before it starts to cost 1000 pound to save a pound!

any chance of a little list or something

Im not bothered about saving loads as Id prefer to tune the engine

but obviously if something saves to me a good few kilos it seems a good deal

I know the wheels are one of the best but I like my team dynamics

Best one for me is to eat salads for a month

take the passenger seat out, you know that once you have taken the mrs out she wont go near it again


zxrlocost - 23/3/06 at 09:55 AM

I must have a right weird missus then because she cant wait to drive it

Go for an ali floor and bulk head and cortina uprights rather than sierra. The unsprung weight makes a difference to handling. And of course the engine. An old pinto is much heavier than say a zetec or a duratec and obviously much more than a bike engine. Then there's brake calipers, discs and the amount of fluids on board...the list goes on

Alloy bellhousing 6kg wieght saving, lightened flywheel although that can be costly.


JAG - 23/3/06 at 10:41 AM

Front calipers.

M16 = 5Kgs

Alu' 4 pot = 1.5kgs

For the pair you can save 7kgs for approx' £300.

Anything that rotates will give you a double weight saving - both linearly and rotationally.

So, lightening the flywheel, using light wheels (light tyres?)

Just noticed that you are using a bike engine - I think they already have light or non existant flywheels

remove the windscreen
remove the boot floor


zxrlocost - 23/3/06 at 11:08 AM

Ive got a bike engine and no windscreen already


smart51 - 23/3/06 at 11:16 AM

13" wheels + tyres may weigh 16kg a set less than 15" Pick some up on eBay and sell your old ones. Might not cost much at all.

Solid front discs over vented. Save about 5kg, cost £100 - 150 maybe

Drive in your socks?
get a haircut?

reduce the water capacity of cooling system...

light wheels, light uprights, light hubs...

diff with push in shafts, single strand loom, thinner body panels, smaller fuel tank, fibreglass seats with no upholstery...


David Jenkins - 23/3/06 at 11:24 AM

In my case, it's losing weight by dieting!

I've managed to get rid of 12kg so far, with 9 more to reach my target (in English, 2 stone lost, 1.5 to go).

Haven't noticed the car getting any faster, but now I can move quicker!

ok cheers for the advice

gonna do celebrity detox

Windscreen
Wipers
Heater
Expansion tank
Wheels/tyres
loose drums and fit calipers
Wilwoods/hispecs & discs
Interior trim carpets etc
Bellhousing
Boot box
Petty struts on roll bar


ChrisGamlin - 23/3/06 at 12:39 PM

As mentioned the wrong wheels/tyre combo is one of the easiest ways to add excessive weight, so keep them small and aim for under 12kgs a corner overall (or 9kgs if you want 13" Barnby rims and ACB10s!), and the seats are another easy one, thickly padded armchairs will weigh 3-4 times more than a GRP shell at ~4kgs and probably cost you more!


wildchild - 23/3/06 at 12:54 PM

go for the ariel atom approach and don't bother with panels?

on a more serous note, bike battery rather than car battery is probably worth a few kilos


G.Man - 23/3/06 at 01:25 PM

Oh good point, bought an aircraft battery at a show last year, donnington i think, and it was extremely light... they had another one that was suitable for my cosworth engine and it was tiny compared to a stock car battery and the weight difference was incredible...

Think my current battery is like 1.2kg's or summat rediculous..


chrisf - 23/3/06 at 01:44 PM

I agree with ChrisG that seats are a great way to save some weight. The fully padded steel framed jobbies many use must weigh quite a bit. I used some carbon Tillett seats and they weigh around 2lbs each. They really didn't cost as mush as one would suspect.

Thos Triton seats look like a great weight saver as well.

I thought drums were lighter than a disk setup?

Chris.

there is about 0.5 kg per pair difference


Winston Todge - 23/3/06 at 02:57 PM

Ta smart but which is 0.5kg lighter? The drums?


PaulBuz - 23/3/06 at 03:13 PM

MT75 is 7kgs lighter than type 9 g/box

DURRRR!!!
Sorry just realised i'm in the BEC setion

cossey - 23/3/06 at 03:21 PM

drums are lighter but if you get the vag rear calipers then they are lighter than stock drums.

ditch the reverse mechanism worth about 5-10kgs.

lighter propshaft, becs are lightet than cecs so can get away with a lighter prop.

push in shafts,

freelander diff (supposedly 8kg lighter but i dont believe it),

take all the excess junk out of the bike loom,


Chazzy - 23/3/06 at 05:46 PM

Having the confidence NOT to drive everywhhere with a tool kit capable of a roadside engine overhaul.

depending how you build/drive it it may get gradually lighter anyway

they're collectors cars...... you run along behind them collecting the bits.


JoelP - 23/3/06 at 06:11 PM

my mate can make lots of stuff in carbon, so i might get him to clone my bodywork into cf. He's not been doing it long but does it full time as a recent addition to his fibreglass activities.


RazMan - 23/3/06 at 06:58 PM

I'm not sure which battery you are using but you can make a substantial weight saving by using an Odyssey battery - less than 6Kg

Hi.

Where can one buy such batteries? For what kind of prices? What is it's capacity?
I'm using a bike one, but although small it weights a lot...

Thanks,
Joao


G.Man - 23/3/06 at 11:15 PM

will have a look when i am next back with my car...

I got mine from a stand at a kit car show at donnington...

Be aware tho, it was £75
