Vw aircooled 1600 draw through turbo carburator

Whats up guys, i just finished installing a draw through turbo setup on a little vw bug with the 1600 engine. The thing is i hear the turbo spool up but im sure im not generating any boost. Can any one help me understand why its not generating boost so i can fix it. Im running a webber 44 fdi carb with a carbon seal td04 turbo and external wategate with a 5lb spring. I posted a pic of the engine setup if it help with anything, thank you.

Hola amigo! Did you ever figure out the problem withe your Vocho not making boost? It's very interesting. I built a Type-1 racing motor and I'very been wanting to turbo charge it too.
