An interesting test with a turbo and supercharger on one engine. DPUK.

Although not Audi related, here's an interesting dyno session on a motor with both supercharger and a turbo.

There's a forum member who's done it to a couple of his projects. One was a urs4 and the other was a b4 saloon.

Nice! It’s always inspiring to see fellow enthusiasts modding their projects like that.

Very interesting, thanks for the link... I've been day dreaming about building a twin charged G60 engine as I happen to have a good complete one knocking about. However decided it's going to cost way to much money, be a lot of hassle, may go wrong and parts for G60's are now hard to get so I'm much better off selling it in bit's and keeping things simple with a 1.8T...

Someone in the USA has built a twin charged 1.8T engine using a G60 charger, there's some limited info regarding the build on Motorgeek and I think there's one in a MK4 Golf on the continent which I found some very old video footage of doing dyno pull's.

Who know's what I may do in future if it doesn't sell, I could use the short stroke 3A bottom end from my B3 80 and G60 etc head to build a twin charged 2.0 8 valve engine... I'll keep day dreaming for now though.
