Ferrari Mailing List: Re: 930 Air cooled v. 512BB

[Rick Moseley (ramosel]

Doug,

I believe the name you are looking for was Michelle Mouton...  she came within a point of winning the rally championship then went to Pikes Peak and destroyed the existing record at the time.  I think she only did it once.  After that Audi brought Walter Rorhl.(spelling?)

On the street, that "disappointment" only lasted one race... Long Beach.  By the time the second race of their first season came along Hurley Haywood was dominant.  It wasn't until Hans Stuck discovered left foot braking did "Donohue's unfair advantage" come back to the race track.   Yes, watching him dance on the pedals was a real treat.   I'd imagine pedal sets had to be changed due to wear as well.   So race directors added more weight, restricted the turbos and made Audi use smaller tires...  They still killed.  Next year they let everyone use bigger tires.... Haywood and Stuck would circulate until every else's tires went off, then they attacked (visciously), finished one-two and won everything.   It wasn't just 4 wheel drive, it was the Quattro center diff. and the instant slingshot horsepower of the I5 using left foot braking with the right foot mashed to the floor to keep the turbo spooled.  At Watkins Glen in the rain I think they lapped the field... twice.

There was a big engineering study in the early 70s on the efficiency of cylinders vs. parasitic loss.  It showed the best combinations were I3, I5 and V10s.   Obviously, F1 went to V10s and Audi was very successful with the I5.   But other than a handful of other motors you just don't see the "efficient" designs in play.   The world is stuck on I4, V6, V8 and V12  (and Peter is correct, the road going Ferrari flats were 180 degree V12s, not boxers).

And to bring this back full circle on the air cooled vs. water cooled topic....  VW bugs are boxers...  Subarus are water cooled boxers.

Rick

Thanks Rick – what a skill for the driver – what craziness for the onlookers.

 

Yeah – Audi Quattro.  When they first came out didn’t a young girl set several Pikes Peak records driving one?

 

That and the poor Audi turbo when it first out was a disappointment – then Hans Stuck came along.  Camera inside the car focused on his feet.  WOW.  The guy looked like he was playing Flight of the Bumble bee with his feet.  Oh, and the Audi Turbo Quattro  super shined.  What was his trick?  Hans said just keep the engine full on all the time – don’t let up.  Heh heh

All true, Rick, but a standard 930 doesn’t do any of those things!

Doug, Doug, Doug....

That would depend on whether or not you like the sound of spinning turbos, waste gates whistling and pop-off valves.   When interspersed with the sounds of a sewing machine engine at full tilt boogie and add bit of exhaust....  its a thing of aural beauty.

 

But my favorite sound of that era... was water cooled.    Audi Quattro S1, Group B - Mikkola at the controls. 

2-1/2 minutes of ANGRY engineering at the hands of a master.   https://www.youtube.com/watch?v=cDRkHXMHqFo

 

aaaaahhhhhh.......

 

 

512BB?  The one with 27 (seemingly) Weber carburetors?  If so – I believe it would have had the 930 beat for sound.
