Re: RS2 turbo

[Thomas Tornblom <Thomas.Tornblom@nexus.comm.se>]

With all this talk about getting more oomph in our audi turbos, I am
wodering if anyone has tested fitting two turbos?

I read an article in a swedish car mag a couple of years ago about a
Volvo 245 that a turbo shop in Gothenburg had put two turbos in.

The interesting thing about it was that the two turbos was connected in
series, and that the turbos was of very different size. The turbo
closest to the engine was small and would thus give good low end
performance while the other was a large one giving the real boost.

They would be connected something like:

engine exhaust -> small turbo (with WG) -> large turbo (with WG) -> pipe

engine intake <- intercooler <- small turbo <- intercooler <- large
turbo <- injection metering house

They got over 400 hp out of this screamer and during testing they
broke several clutches and diffs while burning out in 4:th gear on dry
asphalt!
