I doubt it, it was post for sale in 2006.
Be very lucky to gain anywhere near quoted power without a lot of other work like cams, head work, full exhaust system.
Had 1 on my Vectra B with cams, full exhaust and remap and it only gained 20bhp switched back to standard manifold, ported head and Schrick cams not DBilas then gained 26bhp after mapping.
£/bhp the supercharger is much better value for money
