Looks like Ruf has more or less bypassed the 997/VTG Mezger technology for his big power creations and it looks like he was right all along as I understand Schmirler is now turning away from the VTGs since they are limited by their size (hot/clever side) to about 700PS.
Schmirler is now basing the latest and greatest Porsche tuner engines on the 3.9 litre Alzen/H&R mission 400 engine which ran at 1054PS and attained the required 400kph.
They are now attempting to use this base engine and slightly smaller conventional (but special) KKKs to produce 1000NM @ 3200rpm and 870PS - as per Ruf the Porsche 997 electronics will not play with conventional turbos and ECU boost control so they are trying to marry a Bosch Motorsport 4.4 unit with the existing Porsche ECU..... All sounds a little too much for me

BUT that was quite a number of years ago, and who knows if this plan still holds.
it does make sense to want to do though, from a brand standpoint (i.e., really lay claim to being a bona-fide manufacturer, what with having your own NA and monster turbo motor).

This is a stunning car, really love what Ruf has done....
Need to chill above, begining to sound a bit "fan boyish"
Ruf is a "manufacturer" like 9ff and Techart, it is a German thing.
Ruf does "build his own engines" but they are very much Porsche engines and the way he tunes them is just like other top end European tuners like Techart, Sportec, Manthey, Weissen, Schmirler.
Stating "is available with PDK" sends a sigh through every Porsche nut as we know instantly that this is not a Mezger engine and is the fabled Dfi unit.
Ruf has undoubtedly fettled his version to stay together at 620PS/825NM using special rods, pistons and head gaskets but (as he will know) this engine has a limited structural integrity compared to the Mezger and when it wears out can not be refreshed so easily....

Hi TB 993,
Well, RUF also said once that the Mezger engine can do without problems 800hp..9ff has even done on a GT3 block more than a 1000..and they seem to last.
However, from what I understood here - RUF didnt use the 9A1 991 engine for his tuning here...both 991s here are V8 right?
Most tuners als have refrained from boosting more than 600HP from the 997.2 9A1 turbo engine..the new 991 turbo will also have "only"..540HP..
So RUF clearly decided against the 9A1 engine..but also against the Mezger engine..- that one he replaced by his own creation..
