<VV> turbo distrubutor

[JVHRoberts@aol.com]

I'll put in a qualified maybe on the Cosworth. My GF at the time had one of 
these, and I was amazed that I could NOT advance the ignition far enough to get 
it to detonate. AT ALL. I even got it to the point where it was bucking 
against the starter, and it STILL wouldn't ping! 
Given that it was a 4 valve engine, with above average combustion chamber 
design, even by today's standards, only 8:1 CR, and not the most aggressive cam 
timing probably had a lot to do with it. So, it was already running about as 
advanced as it could anyway. 
I also don't remember if there was any electronic intervention in the timing 
of this car. The EFI was digital, if memory serves me...
However, this car is a special case. Almost anything else will run a LOT 
better with a functioning vacuum advance.

And if this was the case for the Cosworth Vega, leaving the vacuum advance
off it was stupid too.  The absence of a V.A. is fine for a WOT-only car,
but if it will ever need to be operated at part load, it's a terrible
mistake. Performance, driveability, and fuel economy all suffer. It's a
triple loss.
