Last chance saloon for guesses

We've got Reads 90 who has guessed at 1500kg. Which is about 350kgs less than Perv's challenge spec 88" Bowler - which would be a helluva achievement - what a muppett

All the way to Nige's red-wine fuelled 3 tonne +

There isn't a prize BTW

Well i was being very optomistic

And i know you were aiming to get it as light as poss

I am aiming for 1700 for my truck, comp ready

[Tonk]

your ego weighs more than that

[reads90]

hey weight and see

This weighs 1600

[Mark90]

hey weight and see

Is that a clever pun or bad speeling?

for once not a spelling mistake it was a clever pun

[FridgeFreezer]

Axles = 500kg

Wheels & tyres = 400kg

Body = 500kg

Engine & transmission = 500kg

Paint = 25kg

Bling = 100kg

= 2025kg

[Mark90]

You would say that

[MogLite]

Okay - the scores on the doors

You can see the little logo of the car which shows front/rear & left/right if you can't read the writting on the scales

GBMUD - pretty close there chap

only 100kg for Bling.

Come on Jon . Its andy's truck, the king of Bling, got to be more than that

Looks like with a couple of spring packers under the front left and rear right springs, you will end up with virtually 50/50 weight distribution front to rear, and left to right.

God you are really the king of bling. Where the hell did you get that bit of kit, you tart

NAh NAh don't tell me , where you got most of Moglite EBAY

about the same as a challenge prepared 90. Pretty good I would say. It looks like the spring rates or the platform height is not distributed evenly; it is trying to balance on left rear and right front.

It is set up like an ovalracer. What could that be?

And with me on-board

Blame the wife for not zooming the camera - and me being too lazy to crop it - but you get the idea.

FWIW - my guess was 2400kgs - so I'm made up

Its about the same weight as my Ibex

I'm very happy with the front/rear balance

[Mark90]

Nice, rather well balanced too.

The springs are cast offs - 2nd hand Procomp +2's that are well knacered. But I need to know how heavy it is before I can calculate spring rates and ride-heights.

Unless the springs are way off - I'll probably not spend any money - but go air-springs.

I've not really measured the ride heights.

The engine/trans isn't central in the chassis - its offset for clearance.

Ali - that is about £1200 worth of Longacre corner weight gauges - as used by race car boys. I borrow it off of my mate who hill-climbs an Escort Cosworth.

We all have to get lucky sometimes.

hey lighter than my old 90 then

Nice bit of kit though

As well as possibly tired springs, it depends on how level was the concrete on which the gauges were stood? A bit of camber or a dip in the surface can throw the corner weights right out, as could uneven tyre pressures across an axle. If the springs were say 200lb/in, then a quarter inch dip in the surface at one corner would unbalance the corner weights by ~50lb. The axle weights and hence total weight would be correct though. The race car boys take the time to ensure the pads are levelled before adjusting corner weights.

The question has to be asked - is a ~3% variation in weight at the axle ends all that critical in this application?

intresting as my 90 is very similar to your old one and only weighs 2180kg loaded up

including the tasteful wood lining inside that weigh 30kg on its own

Andy quite remarkable to get the weight as low as you have I expected 2500+ at least

The concrete is pretty level - it was a proffesionally laid slab.

I've got frames for the scales that allow you to level up the scales perfectly. But that is probably taking things a bit far as you say.

Overall weight and front <-> rear balance is enough info for me at this stage.

ha lardy!

not a bad result though Andy B)

Dolly,

Are you getting into cad design? Which program? Wonder what the rest is going to look like..

Daan

[will_warne]

Well done Andy. Was that weight with you and the co driver on board? The other big plus point is that you've got a lot of weight down low with those axles which should nicely offset the high engine and gearbox. I'd be well chuffed if I were you

[dollythelw]

solidworks Daan,

just some toys some friends are knocking up - more bling than its humanly possible to gaze upon without going blind

Im still using Autocad and crayons - Ive spotted a problem though, the wax from the crayon is difficult to rub off the screen
