1952 / 1500cc typ 527 Engine / Split Windshield Cabriolet

#1 Post by Joe Ruiz » Mon Mar 26, 2018 3:32 am

I have a couple of questions concerning the 1500cc type 527 engine for a Feb. 1952 Cabriolet.

1) I was reading another post by James Davies stating that the early 527 engines used the short wire mesh air cleaners for the 32PBJ carburetors.

"The earliest mesh filters for the 32 PBI carbs on 527 engines were short. This is circa 1951-52. Then they became tall in mid-1952.
Then they remained tall through the rest of pre-A production. Both the short and tall from mid-1952 onward had just 2 lines of
German text on them. Period photos from magazines show both the short and tall in mid-1952."


According to Porsche records, the first typ 527 engines used SOLEX 40mm carburetors WITH adapters on top of short, 32mm intake manifolds.
They used the tall, wire mesh KNECHT air cleaners. Can someone confirm/elaborate on this?

2) Did the engine use the fan housing that had the "welded" seam running along the topside or was like the later cars similar to 1953 on up?

Thanks for your help.
