Thanks Jason!
But I must comment on the "relative reliability" part
If you referring to the broken rockers, they were just a tuning fault of mine running the engine into overboost and getting hard fuel cut-outs and associated backfires.. The funny part is just that a lot of ancillaries have gotten damage (bend throttle plates, burst boost lines, two broken rockers) due to the boost-cut-outs but the long block is still solid as a rock.
The basic concept of this type of engine has proven itself beyond doubt.
Furthermore, I ran the 350 hp tune over half an hour mostly WOT, full-on at a race track (Zandvoort). I did the same doing 8 laps of 10 minutes per lap (21 km's each lap) on the Nurbürgring last month and your calling this 'relative reliability'? Come on man, just admit I totally detroyed your reason for running a watercooled engine alltogether

But I love you too and truely appreciate your craftsmanship on your car

Its totally amazing that the 103 cast-alu bored Mahle-Oettinger cylinders held up as much as they did, while we all know that a smaller bore would have been much better.
Stock case, stock heads, stock crank and stock rods. "relative reliability'...pfft please! Aircooled FTW!
