The weight saving thread

Fredrich, what do the remmele doors look like on inside?, all cut out or have factory style pressing?
cheers Richie

Flat on the inside. Very nice fit but no enforcement or ribbing.

Thanks, i did contemplate doing it like that, wold have been much simpler but am sure it would need to be thicker to have similar strength

cheers Richie

That door looks amazing 

Not knowing a lot about this at all, I assume they are two pieces bonded together?

Yep just like a stock door, 2 pieces joined together

Very impressive.
Are they going on the pan cab or the chassis cab?

Chassis car, I haven't even seen the other car for 2 years nearly!!!

Both sides are now done, decided to fabricate my own hinges as the stock VW hinges are really heavy, with everything I removed  weight saving is 31lbs per side[just over 14kg] so total of over 60lbs is huge    I will add some lead right at front of car now to help the front to rear weight balance and car will be lighter as well

How about this weight saving?
The company I work for (Composite Design Sverige AB) has been on the journey with Koenigsegg since the first prototype.
So a lot of inventions started here. Like the CF rims. Since some years they do them inhouse. But we did several hundred.
This one is built for Micke Svens Spezialmotorer.
He does retro axial driven horisontal cooling for Porsche racing engines. We deliver in CF and regular epoxi fibreglass.

This is what was manufactured by us and used in the world record holding 407 km/h Koenigsegg run in USA.
Niklas Lilja, the driver not only likes the rims but says that with that huge reduction in large diameter rotational weight, the car behaves significantly different in many ways, handling, braking and acceleration. All improved so much he can simply feel it.
Not for us VW freaks (yet) but very cool!

Last one and what I expect to see soon on our cars.
The Koenigsegg valve covers. This is not so difficult to do for our engines.
Who will be first?

Ha ha ha! 
I had a visitor at work and when I saw these in the conference room, I could not hold myself.
How about this 2 kg weight saving?
Engine rotational mass! Not just on the car.

No, stop before you get lost in dreams, the design and purpose is for OEM engines, that are usually not opened/serviced.
They are glued in place with a special tool.  Yeahh and a special glue.
Well, in fact there is a tool to take them apart too.
No engine has run with them yet, but I can say that the theoretical numbers for fuel savings, makes them very interesting and gives a payback.
Not for aircooled VW engines and not for racing, as designed today.

Some very nice parts Frallan   Like the fan & ring a lot  

I made valve covers for my engine already but have not used them as was concerned about the heat aspect causing it to leak

Whooooooooooooooo 
Frallan, that is impressive, damn cool.

[mikko k]

Very very nice parts! 👍 But not for poor racers.. 😥

So I was chatting with some buddies last night and I came up with an idea for a rear-seat delete made out of canvas and a couple of strengthening ribs. My idea is to have it anchored at the points where the rear seat crossbar is bolted down, then have it stretch up and hook into the little metal extrusion for the rear parcel tray carpet, with one rib running across the middle, right where it meets the rear wheel wells, and one running across the front, between the anchors, to keep it from pulling too far back. It's obviously still adding weight over just taking everything out alltogether, and it's not quite as practical as a big storage box, but I think it's a neat concept that could be done cheaply and still look good enough for a street car, while providing the necessary "cover" over the battery. I'll try drawing it up later this week and upload pics here.
