How did you do the carbon turbo intake ?

I started with a 4” aluminium hose, same as from the kitchen fan…

I placed the hose like a “snake” from one turbo inlet to the other passing as close as possible to the front opening with the center off the hose. With the aluminium hose in position I wrapped a lot of tape around it. To get a smooth surface I started with a silver racing tape all over the hose. Then to get the surface more shiny I wrapped one layer of aluminium tape over the racing tape.

After the preparations on the hose I started to add the fiberglass on the hose construction. The next day when the fiberglass is dry I remove the hose from inside the fiberglass.

Now there is a fiberglass “snake” with a 4.5” inside diameter !

Next part will be to get the air in to the “snake”. With the fiberglass “snake” in position I start to cut it wide open in the direction to the front opening. After that I start to fit some thin sheet off fiberglass to the opening, one layer sheets off fiberglass is real thin…

After the sheets are finally cut to the right size with a paper scissor I start to assemble the sheets to the “snake” with melting glue. Then it is time for some more fiberglass to get the sheets to be fixed on to the “snake”.

The next day when the fiberglass is dry I start to grind the outside off the fiberglass construction. When the surface is grinded I put on some putty to get the surface as flat as possible and grind some more...

Now when the thin fiberglass construction is finished I start to add two layers off carbon fibre to cover the fiberglass all over, still using the same styrene plastic mixture as to the fiberglass.

When it is dry the carbon/fiberglass construction is finished but there is nowhere to connect then hose in between the “snake” and the turbo inlet flange…

So the last part is to turn a aluminium flange that fits inside the “snake” on one side and with the same size as the turbo inlet flange on the other. Four hours later it is done and the new aluminium flanges is glued inside the “snake” with a strong car chassis glue.

Enjoy the free air pressure from the hose !
