Magnesium case for Porsche Historic Racing.

[Olsen911]

Hello Guys.

Wanted to show you what we are up to.

We are a small Racingteam in Europe, running the Historic Race Series here in Europe with Porsche 911 2.3 ST 1971.



Porsche also did race these cars with the magnesium engine cases and therefore we also have to. But this was 46 years ago.

We are always struggling finding some useable engine cases and make them stand the task. When we finally find some useable cases the pricey bit is all the machine work that goes into make them to racing engines.

And we are seeing most of these mag. cases are becoming more and more fragile and the chance of cracks in these cases after 1 or 2 season is getting more and frequently.







Something had to be done so we looked into the marked to find anyone how produced all new high quality engine cases.

Not such thing existed so we contacted the Historical Committee Europe (under FIA) to whether it was possible to reproduce a engine case and still be able to be approve and participate in the FIA races and the HTP. – Historic Technical Passport . HTP. – Historic Technical Passport are used in Europe as a “stamp” for at the car contains all the correct parts and are authentic in it´s class.

Historical Committee Europe replyed: there is a rule that states” if a part can´t be found and if the factory don´t produce or selling this part no more, A corresponding part can be produced with similar dimensions – appearance and function”

We went to work.





More to come.

Thanks - Cheers - Olsen911 - Tommy Olsen.
