Alfa Spider Performance

["George Schweikle" <schweikg@domain.elided>]

Digesti,

This is a great thread Russ has started, especially in identifying different
preparation levels. My suggestion would be to organize a modification list
for the categories listed below. While all of the information can be found
in various rule books, this would be a great place to identify specific Alfa
modifications vs. rules, and provide a good starting place for people just
beginning to modify their Alfas. I'm not sure what this list would look
like, or if it could be archived, but it seems like a good idea. Maybe an
Excel spreadsheet that could be mailed back & forth between contributors and
users, and with some sort of simple revision/date control. I betcha Russ,
Eric Storholk and I could make a good start, but we're Spider/GTV oriented
and others could chime in with information for GTV6 & Milanos.

1. Street use (emissions compliant and who cares)
2. AROC Autocross & Time trials
3. SCCA Stock class Autocross (Solo II)
4. SCCA Street Prepared class Autocross (Solo II)
5. SCCA Time Trials (Solo I)
6. SCCA Improved Touring racing (IT)

Comments?

Subject: L Jetronic Alfa Spider Performance


I have been asked what to do to wake up the performance of the L Jetronic
Alfa Spider.  (snip)

I build the 82 in 1995 and the 84 was built in 1999.  Both were built with
SCCA race and solo rule books in mind.
The 84 is a dedicated race car and was built for the Improved Touring race
class.
The 82 was sort of built as an IT car, but with thoughts of SCCA Street
Prepared class too.
Both rule books require stock camshafts.
The rule book for IT requires a basically stock engine with a stock air flow
meter, stock intake manifold, stock camshafts including VVT.
The IT rule book allows head cutting to achieve up to half a point increase
in compression.  The IT rules also allow 0.040 inch (1 mm) oversized
pistons.

Since the 82 is a street car and occasionally autocrossed in Street
Prepared, I could modify it further.  The SCCA Street Prepared class allows
pretty much unrestricted intake.  That means Webers are legal.  I am not
sure what all can be done legally with an EFI in this class.  I guess I need
to read the rule book I just bought. Both cars have modified suspensions and
wider sticky tires.  I could write a whole other article on that.
