Hello Hubert, always super busy,are you doing the thermal insulation of the ceiling?
"Engine 1339 is causing some headaches because more and more issues show up"
"Developed some basic ideas on how to optimize the engine using original components only and in a second step do some naughty things . . ."
Are you designing a super 400 hp engine?
yes, the ceiling and the roof are more than 100 years old, there was no insulation. There are two main reasons to do the work 1. save energy, 2. reduce dust. When I pumped up the volume of my stereo, dust started gushing out of the gaps.
-some of the valve springs were broken, most others weak
-the engine had been driven with too small valve play, at least one cam of the camshaft is damaged, the camshaft is beyond repair
-the tappets are worn
-some of the rocker arms have griped(?)
From all the engines, people I know, my friends and I had checked on engine stands there was only one performing as promised. It was a 2.5 "1C" making 118 hp (should: 119hp). All the 3Cs and 2.8 3Cs ended up at 127 to 129 hp.
Back in 2009 I participated in the Gran Premio Nuvolari with the GT. One leg we had some problems getting rid of a FIAT 1100 Berlina (surely "elaborata"). That was the moment the idea of freshening up the engine showed up for the first time.
The primay target is to reach the factory values for power output, keeping the engine "original".
The other thing is something I should not talk about in public because I will receive a shitstorm. That is building a naturally aspirated maximum torque engine. That idea came up when I spent a day with my Dutch friends having a glas of wine and a couple of Genevers. I heard of a bored 2.8l engine brought to 3,0l. The makers abandoned that project because they did not get the waste heat under control.
The cooling circuit is under control at "the Farm", so 3,2l or even 3,4l should be possible.
