David, Thanks for your introduction to marine engines. From my experience with VW SDI and TDI engines I like to give you some more details to answer your statements. >Incidentally it would appear from one of the >illustrations on the website that the RPM of >these motors will be below 4000, which is in >accord with marine usage. The max RPM is limited to 4500, which is anyway the maximum RPM on vehicle Diesel engines. Compare http://www.vw-marine.com/deutsch/motoren_tdi115-4.html with http://www1.vw-online.de/technik/4_pumped/rechts2.htm or http://www.vw-marine.com/deutsch/motoren_tdi150-5.html with http://www.vw-nutzfahrzeuge.de/deu/technik/111kw.html Are there any difference in power/torque diagrams? (150 hp app.. 111 kW; 115 hp app.. 85 kW) >Anyway, what I'm trying to get at is that these >engines will be considerably more expensive, VW will sell nothing for cheap, you should know, but VW Marine isn't on the market yet. No one knows the prices for the engine and where to buy. You will get to now it beginning next year. >heavier, Really, not much. There is the enhanced oil pan, some covers and the water-cooled turbo and exhaust manifold. What does it take, 10 pounds, 20 pounds? >and less powerful than the equivalent automotive >engine. This is really not true, compare the links. I got some more detailed descriptions in German language. As time will come I will send the details. Regards Helmut '80 Vanagaudi |
