Re: groupe B 10V motor 330bhp
I would think at least 2 bar boost minimum? The rally ur-q was also
6:1 compression ratio, combine this with high octane witch's brew gas
and you can run some serious boost pressures. Pretty much nothing
happened until about 4-5krpm and then BANG! Walter Rhorl does a rather
nice description in the Audi quattro Experience (I know that was the
Sport but I think the boost lag is probably quite comparable to the
early ur-qs if not quite as explosive).
Does anyone know if the alloy block motors were 6:1 compression ratio?
That's certainly something most salesmen would have kept hidden, the
WX/WR ur-q is bad enough with 7:1!
Is it possible to request homologation papers for older cars from the
FIA? Anyone have the homologation papers for the ur-q?
