Dave.

Still have that old Audi film on VHS with Walter Röhl on the San Remo in the Quattro.

Also loved the sound of a BDA reverberating through a forest.

Only heard it a few times, the first time we were checking out Glow Worm tunnel near Newnes and someone was doing a test run up the valley.
My two mates and I just sat on the side of the ridge listening, absolutely captivated.
I think I was only about 15 or 16 at the time. It made a lasting impression.

Geez Coops, you must be getting up near Pedro's years

Back when I was a young fella karting, my engine builder was the owner/builder of the infamous 'Trench Digger' Milodon Sprint Car Chev engined Commodore that Wayne Bell piloted.
When Belly was piloting the Corolla Levin we went out testing with him a few times, but I never got to go for run unfortunately. He came kart testing with us a few times and used to have a few laps in my kart, just for fun, and when my mates Dad was out of circulation for a bit, we had the use of his Datto 720 sweep ute for our kart trips.
Amazing how quick an L20 datto engined ute with twin 45 Webers is

I worked in many pit areas that Mr Bell also went to,,,

Pedro, as a result of the spectacular loss of life during the 'Group B' days of rallying, FIA decide that it was easier to limit the power of the cars rather than limit the poor crowd control that allowed too many people too close to the action.
The format went to 'Group A' based on real cars and a drastic cut in power. The focus went to suspension, tyres and TORQUE.
Cars are now required to have a 32mm (yes 32mm!) restrictor up from the turbo. As a result greater airflow results in more inlet turbulence/ reversion etc.
That said, the current crop of ~280kW WRCars have far better stage times than the 550kW Gruppe B monsters.

Dave.

hmmm,, two things spring to mind,,,
to compare times, it has to be the same section,,,
and if it IS,,
I'd certainly hope they'd be faster after practising for 30 years.

Talk about sprung big time

Don't need to be that old to remember that one. Quite a clever design it was though!

To hazard a guess on the short rev range , It would most likely be the restriction they put on the size off the air intake to try and level the playing field: limited air in= limited revs. But i am not 100% sure if that class is covered by a restricted intake.

could be,,

in our case the 5900 limit is set due to small injectors,,
another 1500 revs are available (and the nice bump in playability that goes with it) with bigger injectors,,
just add $$$$.

so maybe there is an "common" injector used,,

Can anyone else see the insect on Rick130 post,or is it just me.....

How did that get there
