I feel  your pain.  The vintage organizations are very inconsistent on
this  sort of thing.  SVRA once required 1.25 SUs (although I  consistenly
saw 1.5s on cars at their events) but in the last few years  their rules
have changed considerably. 


David,
 
As you know, I have been Technical Director of SVRA since 1991 and a racer  
since 1982. During that period, SVRA has always recognized a single Weber as  
being equivalent to 2 SU carbs across the board regardless of make or  model.
 
There has never been a size restriction (i.e. 1 1/4" vs 1 1/2")  
 
I don't know where you ever got the idea you state above. VSCCA? VDCA? 
 
The situation with groups requiring Homologation papers is also very  
draconian in my opinion, in the year 2007.
 
One need only to examine a copy of the FIA yearbook for (take your pick)  
whatever year you want to and you will find how difficult it is to apply this to  
modern vintage racing.
 
It all depends on the "Group" a particular event was being run under.  Groups 
1 & 3 where essentially "showroom stock". Groups 2 & 4 where  improved groups 
where carburetion was "free". 
 
A sports car running Group 3 standards was limited to exactly what the  
factory stated on the official forms.
 
However, most events were actually run under Group 4-5 specifications, and  
Group 2 for sedans, the equivalent of Group 4 for sports cars.).
 
It is silly for organizations to try to refer to these regulations "by the  
book".
 
However, if they want Sprites to have 1 1/2" SU's, just say so. Don't try  to 
justify it by going by the book.
