But compared to mondern day wrc cars i think they would be slower throughout a stage because of technology, but still no comparrison for the noise!!!

The group B cars are indeed slower than the WRC cars these days becuase of trick diffs, better tyres etc.
The WRC cars are meant to be limited to 300bhp but they are more like 350+bhp and maybe over 500lb/f of torque.

To limit power, all forced induction (turbocharged) cars are fitted with a 34 mm diameter air restrictor before the turbocharger inlet, limiting the air flow to about 10 cubic meters per minute. This air flow limits power output of the engine to 300 hp officially, although the latest WRC engines are believed to produce around 330-340 hp in spite of the air restrictor. With this technologically easy to achieve, engine development is focused towards producing an engine with a very wide powerband (or power curve). Generally speaking, a power output in excess of 300 hp is available from 3000 rpm to the 7500 rpm maximum, with a peak of 330-340 hp at around 5500 rpm. At 2000 rpm, which is the idle speed in "stage" mode, the power output is slightly above 200 hp [2].
