decklid hinges?

Hmmm does it really looks like? Hinge is correct, BUT it's only one. The left one is stock.
A little help:

It's at the left front fender...

hello,

hinge for the filler flap?

[Flieger]

Because of the three bolt holes I thought they could be door hinges but they looked too small. But I don't look at the door hinges on my car very often.

Finished the camber plates. Color change and DIY bushes to save weight (another 136g) and lift strut position. Furhter I drilled the battery mount

Wow Roland your machining skills are impressive...can't wait to see your car completed.

Thanks

Me too... But we have to be patient. Not this year.

Amazing work. I was mesmerized. Did you replace hood and rear tail? Someone know the diference in weigh between carbon and fiberglass, For the replaceable parts?
What do you expect the final weight to be?

Thank you

Hood is stock but drilled. Rear deck lid as well:





Tail is homemade out of FG/epoxy, check my thread:

Homemade Whaletail

Carbon itself is about 25%percent lighter than FG. Different specs at all, so not comparable only by weight. Same for aramid, even more like steel, very durable, but not easy to work with, mulish stuff, ask me how I know

I have no idea how much the car will weight in the end and there is no goal. I just can tell that it was at the beginning of this thread about 1040kg and will be maybe under 1000kg at the and, we will see...

[Flieger]

The main determinant of weight with composite parts is the resin volume fraction. If you do a wet layup and don't squeeze much resin out the parts weigh a ton. If you use pre-preg and put it in an autoclave you have almost the minimum amount of resin so the parts are lightest and strongest. Extra resin doesn't gain you any strength. Just make sure you don't have dry fibers.

Hi Roland, any news?

[aseem]

Fantastic thread Roland. I'm amazed of your relentless drilling, machining and anodizing work. You are a very good DIY representative. How can the rest of us send away parts for anodizing now, after reading your thread. Your parts looks beautiful.


In your search for a lighter car, have you seen this site from DP: Innen Look at that ventilation box, reducing the wight from 6500 grams to 300. This must be something for you? There are some other trick parts there as well, but expensive. I talked to DP Motorsports at Techno Classica Essen this year, and they had some really nice light weight builds there. I test sat this, which is really nice (not a turbo though): Sleeper marks 50 years of Porsche 911 - IOL Motoring | IOL.co.za

For those unfamiliar with German, "federleighte elfer" means feather light eleven

Nice find that BOX. We do have MOT requirements for the FAN but that box should work just fine in everyday driving.

I was in vacation in Sardegna until today, so I maybe this week I will make some more progress to show...

Thanks for the compliments!

I've seen this box a while ago, but don't liked it:

First of all, the weight of 300gr is without any blower fan, the stock one is not heavier for sure. The 6500gr is maybe correct with fan and all stock tubing heater regulation etc... I will weight my setup this week to give you an idea of my thoughts and solution. The DP box needs a fan somewhere and if you use one with equal performance, then I doubt any weight saving or improvement at all

[proffighter]

Today, I checked the weight of my setup:

Box, fan and all ducting is almost 3200gr. Add a few gramms for some clamps and knob and you'll end-up at 3250gr or so

For Heater unit and overall pic check this:

Gas heater installation

I did not weighted the box alone, but without fan it won't be heavier then the 300gr of the DP box. Or even lighter

Conclusion:
With the DP box you still need fan, ducting, etc... and therefore I cannot see any improvement







PS Be sure I will find some weight saving potential here too...

[proffighter]

I made some backing plates for the Tarett front sway bar out of stainless steel, went out fine, but thought I could be nicer...

So I decided to made some out of high strength aluminum 7075, what I use for most of my homemade parts. Saved another 20gr over the SS ones



BTW Pic does not show really, but of course there are M8 threads in the part as well

So -- when do we start a pool for guesses on this car's final weight? ;-)

I have no idea, but lighter than before I guess

However, I do not know, what comes into my mind during the assembly, I tend to think about every part while just mounting. Sometimes it stays, sometimes not.

HAHAHA, BS most of the time: NOT
