hi guys quick question for anyone in the know. Does anyone have any idea of the weight of a sierra rs500 or xr4 not looking for and exact weight because obviously both cars will be different. I'm just curious what the weigh of the production line i cant seem to find it on the net i have weights of rally cars ect but nothing of the standard car......

cheers Steve

don't hold me to it but seem to remember a cosworth is 1220kg. seem to think i need to lose 220kg in my project to be less than 1000kg. i think an xr4i was a little less (despite the 6 cylinder engine). i can't remember where the figures came from sorry. as a bit of a comparison i know that an xr4x4 with 2.9i fitted was 1290kg. hope this helps.

cheers mate that gives me a rough guide i thought it maybe around the 1200 mark. Im going to take mine to the weigh bridge at my local scrap yard to get an exact weight it will be good to see how much weight has been removed and get a bhp/tonne estimate

tonysierra4x4

are you scrapping car or just weighing it. what has been removed to reduce weigt.

rs_v8

just weighing her... all the interior apart from front seats and dash board light weight door panels, all the glass remains in the car il put up pics...

links don't work. are all carpets and soundproofing etc still in as these are a fair weight.

tonysierra4x4

thanks jeff. my memory is getting worse (age) lol, but i was sure i needed to lose 220kg.

rs_v8

Cheers im uploading into my garage now so take a look all carpet removed and sound proofing

tonysierra4x4

car is looking pretty good with you.
be interesting for me to know the new weight. even though i have stripped everything possible a larger engine and cage etc will be putting the weight back up on mine. when i removed the wiring loom for respray was surprised to find the total weight was over 17kg. spent long enough finding good genuine bodykit and bumpers etc and looks like i will go fibreglass as major weight reduction.polycarbonate windows save over 20kg apparently.

rs_v8

20kg on glass?? look like a definite then... you got any pics of your build? whats engine you running im running a 4.6 on mine...

still building mine. 2 on the go. mine is having volvo 2.3 t5 converted to rwd ofcourse. time is a factor atm.

not sure why link not working correctly but paste into search bar.

matthewpickup

I thought the weight was around 1170

cheers.... alls i need is a rough estimate so i know roughly what ive saved ... wanna swap your truck



tony your project is sweet!!! What bhp are the volvo engines putting out? i would assume around the 250 mark??

matthewpickup

ah , and no that would be like selling/swapping a child lol

tonysierra4x4

standard engines are around the 250 mark but already modded when i bought the car. currently on a rica remapped ecu with 19t high pressure turbo which makes a big difference.
one is running over 300bhp with torque a little over 350 lb/ft. will probably end up on standalone management so will increae slightly when done.
i wanted reliability more than anything plus i will be having enough fun with that sort of power. tbh a lot cheaper than going cosworth route. the 2nd is totally standard but not realy decided if both cars will be given t5 engines.

rs_v8

Thats some decent power and a lot of torque!!

Do you think its possible to get it under 1000kg? Id think it would be very hard. I bet the touring cars where 1100kg

rs_v8

Thats what im wondering im going to get her weighed as soon as I can.. I think 1000kg maybe a little low near the 1100 mark im guessing stripped like she is......

tonysierra4x4

i think it will be possible but extremely difficult. the cage needed puts the weight back up. when you have weighed yours we will have a better idea. i hope it can be done as it is a nice round figure to aim for.

Carbon fibre bonnet and roof would save around 40kg (around Ł1500 for both though )
Carbon tailgate?
Side exit exhaust will lose a good few kilos as well

To remove more weight out of my light weight car I'm building I am going to send the cage through the floor and put the mounting points for the rear arms so I can do away with the rear beam , also I may remove a bulk of the inner wings , no dash at all just a digi dash mounted off the cage among other things, as I need to make sure it's under 1000kg

tonysierra4x4

are you using a sierra or other shell?

lacey

Base model 3dr sierra

rs_v8

If under 1000kg is possible thats the way to go about it I suppose...

lacey

I hope so lol
