captain chaos Posted September 19, 2008 Share Posted September 19, 2008 I'm not talking about what the blurb said in the brochures, I'm talking about what we owners have weighed the cars at.. I know Julian has produced a very light car, but my Vx rebuild has been a little less focussed on weight reduction (with a Vx motor upfront how could it be 😬) and yet from some of the numbers I've seen on here recently, my car seems to be below average.. DaveK has just helped me flat floor my car and with aeroscreen, 12L of fuel and all other fluids my car has come in at 519kg. How does this rate as a Vx and how far am I away from real world K-series weights? Cheers Gary Link to comment Share on other sites More sharing options...
rgrigsby Posted September 20, 2008 Share Posted September 20, 2008 That seems pretty light to me, many years ago the Se7ens list had an RR and weigh in at Emerald when they were in Brixton, the results are here. On the first page of that spreadsheet are some weights of various cars. My 2.3l Duratec weighed in at 515Kg when I originally built it although it maybe a little less than that now. I friend has a very stripped out VX engined car and that weighs 512Kg so to get down to 519Kg without trying is pretty good Cheers Rob G www.SpeedySeven.com Edited by - rgrigsby on 20 Sep 2008 06:55:10 Link to comment Share on other sites More sharing options...
acw Posted September 20, 2008 Share Posted September 20, 2008 Hi My HPC weighed in at 642kg with half a tank of fuel at the session Rob gave the link to. Andrew Link to comment Share on other sites More sharing options...
rj Posted September 20, 2008 Share Posted September 20, 2008 My K came in at 468kgs with 13l petrol - the car has windscreen & wipers, but otherwise I've been a bit manic. Link to comment Share on other sites More sharing options...

Support Team Shaun_E Posted September 20, 2008 Support Team Share Posted September 20, 2008 534kg with half a tank of fuel. It's a Superlight but has windscreen, wipers and heater. Also it's dry sumped which adds a bit (Caterham bellhousing tank). Yellow SL #32 - member of Drowned Rat Racing Link to comment Share on other sites More sharing options...
AMMO Posted September 20, 2008 Share Posted September 20, 2008 My car was 590 kilos with a Crossflow and old type heavy leather seats (9 kilos each) when I bought it. Complete with hood tools an a half tank of fuel. Now with a Duratec with screen and flares but no hood or tools and with the spare wheel removed (what I call track day trim) it was 518 kilos. Removed the bench seat and fitted S type seats so a bit more now. Both times weighed with the same corner weight scales. Ammo Raceco.com Link to comment Share on other sites More sharing options...
Bertfatal Posted September 20, 2008 Share Posted September 20, 2008 My SV was 582 kg when flatfoored. That includes windscreen, heater, wipers, hood furniture and hood in the boot but with the spare wheel removed. Bertfatal Link to comment Share on other sites More sharing options...
Peter Carmichael Posted September 20, 2008 Share Posted September 20, 2008 There was a recent weigh-in at the Surrey meet. I think Mark Durrant's R500 (with roll cage) came in at about 502kg. IIRC it was 1kg lighter than my K (with full roll cage). Don't know how much fuel Mark had in his, but mine was two litres below brim full.

captain chaos Posted September 20, 2008 Author Share Posted September 20, 2008 I really am quite pleased now...I think my key savings have been swapping to tilletts, some carbon panels and making my own wiring loom. Any CSR weights?...a couple of my mates have CSR260's...what do you think they weigh? Gary Link to comment Share on other sites More sharing options...
paul jacobs Posted September 20, 2008 Share Posted September 20, 2008 My CSR 260 was weighed at the SVA test 3 years ago, and with a full tank of fuel, 8 gallons, leather chairs, heater, FIA roll over bar, full windscreen, sidescreens and hood etc, it came in at 598kgs, which is more or less what I expected, given that the factory quote 575kgs, but I guess that would be without much fuel in.

The Boy Posted September 21, 2008 Share Posted September 21, 2008 Just looked st SVA info. 860kg!!! The car is a Superlight Sigma car. I had full tank, spare fuel, tools and overnight things in the boot, weather, screen, an SVA inspector etc - all that you would take on a trip. I'm more amazed at how quickly you can add weight to the car. Would like to get flat floor setup done. Any recomendations in the Wiltshire area? Sorry to add to this post.

Stationary M25 Traveller Posted September 21, 2008 Share Posted September 21, 2008 Surely 860kg and Superlight don't belong in the same post !! 860kg - are you sure that's not 680 ? Link to comment Share on other sites More sharing options...
combine Posted September 21, 2008 Share Posted September 21, 2008 1991 vx 16v 2L , cornerweighted so weighed accurately , 630kg ! Need to get some weight off somewhere , there's the spare on the back , the leather seats , windscreen , er , what else ? Downhill though maybe advantage ? Also possibly more grip ? Anyway she is a wicked beast with serious overtaking attitude . Oh , could empty out the boot !

The Boy Posted September 21, 2008 Share Posted September 21, 2008 I hold my head in shame ☹️ just checked 360 front 500 rear!!! I did have lots of tools and parts to get me through SVA. How accurate are the SVA? The figure was read on the brake test rollers. I was concerned by the reading and question accuracy. Running only 13" wheels that car dropped into the rollers so was not flat, I think this has made the reading heigher that it was. Learning new skills all the time, 8100 miles completed.

rj Posted September 21, 2008 Share Posted September 21, 2008 850kg used to be the max gross weight. Surely can't have been weighed in at that as a driver then would not be allowed! Link to comment Share on other sites More sharing options...
Lasse H Posted September 21, 2008 Share Posted September 21, 2008 My CSR 200 weighs in at 600 kilos. That is with a full tank of petrol (42 liters) and with windscreen, wipers and doors. I have changed to a Raceco silencer (saved 19.1 kilos ! Thank you, Ammo) and Odyssey battery ( 5.5 kilos less) and cf headlights (2 kilos less). My car also have FIA-bar and integrated dash-board. regards, Lasse H Link to comment Share on other sites More sharing options...
martin b Posted September 21, 2008 Share Posted September 21, 2008 We had a recent weigh in at the Surrey meet as Peter C rightly says Results are here 519 kg is very light for a VX Well done Martin Surrey AR/AO Link to comment Share on other sites More sharing options...
combine Posted September 21, 2008 Share Posted September 21, 2008 Regarding the 519kg vx , it must be a later one as the chassis were altered at some stage ie more efficient use of tubular steel , probably less as well , not sure of the date its in the '7' book which I have lent to a potential '7' buyer .

captain chaos Posted September 22, 2008 Author Share Posted September 22, 2008 From the 'weigh in' results it looks like my car is about the same as Darren's K80 RUM. My car weighed 532 with alot more fuel in... Link to comment Share on other sites More sharing options...
martin b Posted September 22, 2008 Share Posted September 22, 2008 I think, though stand to be corrected that the lightest VX we had was Steve Mells, the lighter Vauxhalls only had 8 valves. Martin Surrey AR/AO Link to comment Share on other sites More sharing options...
