have the Raby/Navarro engine mods been tested?
Couple of dozen cars/engines. Been doing some for about a year and a half. Unknown number of miles on each car. Unknown number of mods to each engine. Design changes along the way.
While I agree that many unit testing over time is what will give us a baseline of confidence, it seems to me that you are holding Porsche to a higher standard than Jake/Charles in the quote below when you base an opinion on the OEM reliability on the number of test miles the new design has run. Didn't this IMS-less design go in the 911 line of cars some months before the Boxster/Caymans? So there must be thousands of new design engines running around the world today.
Please understand I have nothing against Jake...in fact he and I have discussed this very point of quantity testing and he does run himself what he installs for others (as does Charles...when you put your wife in one you show some confidence). It is just I don't want to be a fan-boy and not be intellectually critical in my thinking about his products even as I root for him to be wildly successful.

That'll take hundreds of thousands of road miles to sort out.
I still think the best bang for the buck is to put a Raby upgrade into a roller.
