Long time no see. Lots have happened since last update. We have moved from Stockholm to Dalarna into Marias house, we have also changed jobs so the cars havent been worked with at all. But i started my paternity leave yesterday so i might find some time i hope.

I have made some drawings and a "M-lamp" wich might be interesting!?

The chassie is made in Autodesk Inventor, which is my new tool at work. I don´t master it at all, but since i am going to work with it i need some practise so i thought i make a chassie for the Camaro. Inspired from Roadster shop with some of my own thoughts. LS-engine, dual A-arm suspension both front and back and a Dodge Viper rear end.

We are also going to rebuild the house so i made the house and garage/storage space in Solid Works.

The M-lamp is a birthday present for Maria made in 1,5mm metal TIG-welded.

Thanks an i hope i can make something sooner than 6 months..

I put them on the scale today. The bare one 5.6 kg. With one pump plus filter 7.6 kg and with Volvo 142 oem fuel cap 8.4 kg. OK i think!?

My fuel tanks are finally finished. After almost one whole year of drawing, cutting and welding. A much bigger project than i could imagine. And quite expensive..

Working in Titanium is a lot more tricky than i remember from building the front suspension.
These were my criterias and why i buildt my own fuel tank.
- E85 friendly material (only Stainless Steel or Titanium is OK!)
- Low noise from pumps (Need intank pump, i hate those noisy 044)
- G-force friendly (the comparment with pums fill itself up in cornering and acceleration, and the fuel return goes there too. I dont like the foam stuff)
-Easy construction (Two Walbro 450 intank pumps with pre filter, good for up to 1200 hp and only one filter before engine, one fuel line to engine, and one line back to tank, thats it)
Low weight (Well not as light as aluminium byt almost half the weight of steel)
- 56 liter of volume
