reads90 Posted September 19, 2006 Share Posted September 19, 2006 Last chance saloon for guessesWe'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 Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted September 19, 2006 Share Posted September 19, 2006 Axles = 500kg Wheels & tyres = 400kg Body = 500kg Engine & transmission = 500kg Paint = 25kg Bling = 100kg = 2025kg Quote Link to comment Share on other sites More sharing options...

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? Daan Quote Link to comment Share on other sites More sharing options...
MogLite Posted September 19, 2006 Author Share Posted September 19, 2006 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 Quote Link to comment Share on other sites More sharing options...

Daan Daan 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. Quote Link to comment Share on other sites More sharing options...

DaveSIIA Posted September 19, 2006 Share Posted September 19, 2006 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? 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? Quote Link to comment Share on other sites More sharing options...
white90 Posted September 19, 2006 Share Posted September 19, 2006 hey lighter than my old 90 thenNice bit of kit though 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 Quote Link to comment Share on other sites More sharing options...

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.

will_warne Posted September 19, 2006 Share Posted September 19, 2006 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 Quote Link to comment Share on other sites More sharing options...
dollythelw Posted September 19, 2006 Share Posted September 19, 2006 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 Quote Link to comment Share on other sites More sharing options...
