I have certainly not forgotten that. I mentioned it on a thread in the F1 posts. Porsche is not only a consultant for several firms in the car industry, but also in the motorcycle industry, in the aero engine sector and even in defence industry. Most of this never get mentioned publicly because Porsche, like many contractors, has to abide by confidentiality clauses and cannot divulge its work. An example of Porsche work is the Street Rod engine on Harley Davidson. Porsche has also worked for Lycoming, the aero engine manufacturer.
