Sandcast Solex 40PII on a pre 59 pushrod engine?

#16 Post by Guest »

Bill,
Having someone in the past running them will not make it
legal now unless there is some strange ruling. You said P1,
which is a different carb, I think you meant P11.

Oliver is trying to establish that some push-rod Porsche, somewhere
raced in the 50s using and cast solex PI -- so his customer can use them
now.

Oliver,
The Solex PII were not used on any A models except the S90
Conv. D or 4 cam motors.

Dear Folks,

For a FIA registration I'm looking for any information about a 356 A
(coupe or speedster) with a pushrod engine and Solex 40PII "sandcast"
carbs.
For my project, I need to be sure that one engine like this one was used
in the 50's for racing............and I need to find proof!

Sorry for my not so good english!

Best regards from France!

I have to agree with you about this but there is a well
known vintage driver out there racing a 356A bodied car with
Solexes and gets a way with this because he says the D came
with a S90 motor. My factory spec book shows that the first
S90 was in 1960 with motor number 800101.

Alan
my roadster came out 29th of march '60 and came as a S90 original N° 800306.
but gone long time ago ...

Most A and even pre-A racers are running the Solex 40PIIs because the organizations permit them to. There are more restrictive race groups that only permit Zeniths on the early cars. FIA may not permit it, but SCCA allowed Solexes in the mid-seventies.
You pick your group, and follow the rules.

Solex carbs

#19 Post by Al Zim »

At the time we were finishing with E Production SCCA racing, the A car were allowed to have Solex 40PII carburetors in place of the Zenith. This was probably in the mid 70's. I will bet that Vic knows the exact date. He is younger and his mind is fresher. al

Solex carbs on "racers"?

#20 Post by Dick Weiss »

Al,

I have a few years on you and can remember when 356s were running in 3-different classes during the late '50s and only twin throat Solex carbs were on the Carrera until the S90 was introduced in late '59 for the '60s and onward, but still running in separated classes in SCCA.

Solex PII on 356A

#21 Post by Gerry McCarthy »

All:
I did a little research on this subject, and can not find a sure answer. The last pushrod 356 to race at LeMans was in 1956, A 356A # 56007 with a 1300 (1290CC) "long stroke" engine, 74.5X74 MM. Type 589. The 1300 type 506 engines were 80X64 MM. The 589 could be ordered with 32PBIC or 40PICB carbs. The Monthlery record car , a Gumnd Coupe used Solex "PAAI" carbs in 1951, whatever they are! The 1500 Glocker mid engined cars, and the pushrod 550's of 1953 used 40 PII twin-throat carbs. It seems likley to me that the factory used these highly-developed pushrod engines somewere, in a 356/356A body, although, 1956 is the last year LeMans saw a pushrod Porsche, ( no "production" Porsches were entered in 1954-1955) one of these engines had to show up somplace, backed by the factory. You will need pix. from the factory supported races in Europe from '53 to'56 to find your evidence. After '56, it's ALL Carrera! Good luck![/i]

It's me again,

For my project, I'm working with the appendix K from the FIA, specially with this article (point (b)):


3.3.8 For Non-homologated cars, the following evidence (given in order of priority) may be admitted to prove period specification:
(a) Manufacturer’s specifications as evidenced by any of the following: sales brochures, manufacturer’s handbook, manufacturer’s workshop manual, manufacturer’s spare parts list, road test magazines, all of which must have been published in period.
(b) Evidence that a manufacturer’s specification was varied for an entrant in an event. Any manufacturer’s document, drawing, sketch or specification produced in period, or any magazine article produced in period (specifications in magazines and periodicals of the period must come from at least two sources).
(c) Reports from recognised experts who inspected the car.
(d) Of lesser value, but to which consideration will be given in any specific query, will be books and magazine articles written out of period by reputable authors. Recent letters written by manufacturers, mechanics, engineers, designers, drivers and team members of the period may be considered for a specific car.

And I repeat, I've parts, specially intake manifolds for PUSHROD HEADS, made in welded steel. I'm sure these parts were built before birth of S90 because in 1960 is was cheaper to buy, new or used, solex aluminium manifolds than build one set!

Thanks for your help!

Oliver,
I think the key section is part b. If the factory did a
modification then it is ok for you to do the same mod. If
the mod was done by a third party I think it is not recognized.

The entry papers for -058 only say Solex but Ludvigsen's 1953-1956 Spyder book says that the Le Mans entries (two SLs and two pushrod Spyders) had twin-throat Solex carburetors. They are pictured in a Spyder on page 11.
By the way, does anybody recognize the oil filler in the picture? The size is similar to a Super filler but it has a screw-on cap and may be aluminum.
Old thread, but Karl may have got this wrong, unless there's better photos. To illustrate, here's Spyder #44 at Le Mans 1953 with its twin-throat Solex carbs.
1953 Le Mans_550coupe_1500Super_44.jpg
And here is the #49 SL coupe at Le Mans 1953, and it seems to have the Solex 30 (or 32) PAAI carbs that Gerry mentions in this thread, a carb very similar in layout to the Zenith with a single round intake at the top, but 2 throttle bodies inside. Note the single Knecht mesh air filter, not what would be needed for the twin-throat Solex.

And here's an SL from the grid of 1952 Le Mans, showing the Solex PAAI carbs better.

I don't know how the factory engines were outfitted for Liège-Rome-Liège in 1953, but likely the same on the SLs.
