Porsche 356 B 912 356 SC Super 90, 90PS 1960-69

Wossner Porsche Pistons have an excellent reputation for longevity and performance.   With 3 distinct sizes available you can keep your 356 running well into the future.

In order to assure the highest quality forged pistons, Wossner produces all of their own forgings in a plant separate from their piston manufacturing facility. In this way they can completely control the quality of the forgings which so crucially affect the end product. Made from 4032 T6 Aluminum, these forged pistons will hold up to the abusive life of a high performance piston.

These pistons are made with a slightly greater dome volume than stock so they will increase the Compression Ratio over the factory 9.3:1 to 9/5:1 giving a bit more HP and torque just from the raised compression ratio. If you are using these pistons in  a Super 90, the Combustion chamber will need to be adapted to the larger piston dome design.  The ring pack that comes with the piston kit is a state of the art 1.0mm top ring and 1.2 mm 2nd ring along with a 2.5mm oil ring which help to reduce friction and free up more HP.
