[Vintage-race] FIA Spridget and Webber Question

I thought the FIA allowed any carb as long as it was fitted to the unaltered
original manifold. There is always someone who knows of a Sprite that ran with
twin Webers and eight port head, or that 1480 cc engine and 6" wide
tires...... like the Spitfires and GT6's that run Webers because Triumph ran a
GT6 with Webers in the Macau GP (honest according to Kastner that was it in
1967?) which would make that an interesting car but doesn't grandfather Webers
for all Spits and GT's. Out West here there is a 1967 cut off date in HMSA and
CSRG and I know that CSRG tries to check cars for proper configuration when
they join (they don't make guest cars toe the line ) but many good people will
update their cars after their vehicles are accepted.
The thought is that it's a gentleman's sport and gentlemen will not "update"
and gentlemen won't complain. I always figured if your car wasn't raced at
Lemans then maybe the SCCA guide lines should work? Or if you want to go
faster find a different car? The only pain is self inflicted.

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.
