How far can a Cup's weight loss go?

[MarkCup]

Finally, I know for sure. I got around to weighing the last of what's been stripped today after Rentech Mike had his hands on it again, very pleased with the result...

The first stage (done ages ago) consisted of taking out the carpets, sound proofing, all interior trim except dash and roof lining, rear seats + belts, stereo + speakers, boot floor and parcel shelf, and came in at 65 kgs.

Today I weighed the driver's seat + mount, steering wheel, both airbags, carbon canister, fog lights, roof lining, power steering pump + tank + hoses, sun-visors + interior light, rear wheel/jack carrier, and that came in at 46 kgs.

I've added a race seat + custom mount, steering wheel + boss + spacer, driver's harness, and that lot was 14kgs.

Things I haven't weighed are my destroyed splitter, fuel rail, engine undertray and bonnet sound proofing, or the difference between the manual and powered steering rack...call that 7kgs (Mike reckons the rack alone was an easy 5).

Now I've still got the lardy passenger seat in there, so there's another 15kgs to be had by going for a lighter seat on that side, but as things currently stand, I'm at 917kgs, or 194bhp/ton.

Changing the remaining seat will get me to 197, so if my change to the manual steering has freed up 3bhp, I'll be at 200bhp/ton, for almost no money at all.

:approve: :approve: :approve: :approve: :approve:

I love my Cup.

 

[Bodge!]

headrest!

get it oot!

 

[Alexander]

get rid of the t**t strip and that will save a couple more grams lol!
looks good tho!

 

[DrR]

Take the slide lights bulbs out? Does the clutch cable have a weight on the end? Old ones didn't.

 

[davesport172]

instead of the numberplate, get your reg stickered on! got to be worth a few grams!!!

 

[Schweppy]

Good work.

TWO mirrors.....thats gotta be heavy surely?

 

[Tom Wilde]

I've heard that the engine weighs quite a bit...?

 

[fuel_slut]

Suggestions:

CF bonnet or fibre glass, or remove the metal struts in the bonnet.
Drill holes in panels
Strip inside door metal off
CF door mirros
Poly carb windows
Only run drivers seat
Remove the dash board you pu$$ey
Remove heaters

Must be another 40kg right there!

Good work so far but you need to be more hardcore! he he.

 

[Jordi17]

there wont be any car left lol

 

[Chris n nic]

Good stuff Mark

I have took out -

Everything out of the boot, rear seats including all belts, all carpets and rear cards, centre console + both front seats replaced with Cobra Suzuka and obviously dumping the belts etc from the front....what weight do you reckon that will be?

Chris

 

[Russ.]

never seen a pic of you mark, maybe the next step should be driver weight loss? cut your toenails that little bit shorter? regular doses of laxitive? lol

 

[Christopher]

Excellent work!

 

[Rich]

Start doing some serious weight loss, start chopping out the door and boot inners, get rid of the bonnet strengthening/double skinning.

There is loads of weight to save in removing unused wiring loom.

 

[Michael172]

your renault badge is stil on there.


your side strips are still on there.....

 

[Inferno]

instead of the numberplate, get your reg stickered on! got to be worth a few grams!!!

Around 200 grams a plate if you want to talk numbers! Is your stereo all out yet? And erm... you seem to have gone the wrong way with adding a second rear view mirror - with close on 200bhp per tonne, the view out of the front should take priority!

 

[cleo]

Spoiler? and I'll give you £90 for it

 

[Craig]

lightweight alloys

 

[Jay_clio]

whats that thing on the inside of the roof were a sunroof would be ?

 

[brisa4984]

CF wing mirrors?

 

[Ex-User (19928)]

Did you just weigh what you took out and took that away from the book kerb weight?

Or did you actually weight it ?

 

[Martin]

Good work Mark but I reckon with more work 850kgs is easily achievable.....800 kgs if you went very extreme.

 

[Mark One]

LOL at this awesome piece of car

 

[Mark One]

...But you do realise that you could have a 205 that is the same weight with a stereo and a heater etc etc lol

I know, not the same.

 

[The Boosh!]

love this car mark... seen the vids on the tube and....

YOUR A FKING NUTTER

 

[Henry]

loads you can be doing but it's starting to get more involved now. i'd go for poly windows first - it's weight from the top half of the car, although i think the front three windows are lightened anyway aren't they? (not sure how they might compare with poly).

removing the heater's up there too but you'd probably want to think about how that might that affect the ventilation circuit

 

[cat171]

Good stuff Mark

What about the alloys ? How much do they weigh each ? Can you get lighter ones ?

Classic IAM 'shuffler'

 

[ForceIndia]

You sir are a legend. Light weight is the key to performance, you've taken it to the max.

 

[Dan R]

For god sake dont fill it with fuel. Thatll balls it all up

 

[172Ben]

carbon fibre roof FTW

 

[Marky_]

I'm sure he has specialist lightweight 15"s for the track.

 

[cat171]

^
seen it on some phase 2 valver wheels & set of tsw evo r's I think they are (the yellow ones) Don't think i've seen any others.

 

[Iridium]

I thought it had some mods? Fancy ECU/Exhaust etc? Also, has it been rollered, and weighed? You should do those things now so you know *exactly* what you've acheived, just as a matter of interest

Dan

 

[RickyP]

Is that bar coming off the passengers headrest a mount for a camera? Awesome work to the car.

 

[Steviant]

Remove the heater and all the pollen filter etc Get the battery in there, like the cup cars.

 

[Iain C]

that is my idea of hell.....why would you take out the radio lol.

 

[The Chubby Pirate]

start replacing panels with carbon fibre? Suppose the bonnets a good place to start!

 

[Chavadurkin]

Drive naked...........? Surely your clothes will weigh something?

But please dont ask me to be in the passenger seat !

C

 

[MillerLight]

top and lower grill
wing mirrors
side strips


maybe 5KG there!

 

[Nik]

Trust me, other than to start removing limbs / non vital organs etc, he's not got much weight to lose lol
