Everything. The injection pump is a mechanical device, it has limitations that are impractical to completely eliminate. If you were to set the governor to limit the engine RPM to the maximum safe speed then the RPM it could revv to with a load would be limited. Since the engine can't revv higher th...

I know I am not as knowledgeable as you, so could you please explain to the unwashed masses what does a fuel pump governor has to do with the physical limitations of an engine?

I guess it would be too much to ask to go back to the topic...

I know that you taught Dr. Diesel the combustion cycle named after him (you are too modest to ask for recognition), and Bosch how to do fuel injection. And Lysholm and Garret, among others, call on you when they have questions. And you can grow single crystal multistage compressor blades in your kit...

If you do not break things you are not pushing it hard enough,

bonden_85, any new adventures?

Not trying to interrupt the conversation, I have a question: which manual transmissions are you using over there with those engines?

To increase the performance of a 617.95X engine I assume some head work is needed. What kind of work is done exactly? Larger valves? Porting?

Very nice setup! I need to learn how to build and exhaust manifold for my car. Like yours, I want one the turbo would sit on it instead of connecting to it sideways. This way it would be easier to bolt it without having to hold the bloody thing. I also see that you too cannot stand the hard metal tu...

Does anyone know what Mercedes did when they ran a 617 turbocharged/intercooled engine delivering 230HP in a C111Mk3 body in Nardo in April 29/30 1978 for 12h, with top speed of almost 322Km/h? Did they change anything in the engine itself, whether cam or fuel pump? How about turbo choice?

I saw in the local yard an Audi 5000 turbodiesel. The injectors look like the Mercedes ones, but I am told they supposedly flow more. I plan on yanking them and perhaps the fuel pump too. I may try to see if I can yank the precombustion chambers and see if they are any different from ours.

Does anyone have pictures, ideally not in the schumanautomotive site because I have no access to it, of a GT37 attached to a 617 engine? AFAIK people here have done it and I too would like to try that since I have one doing nothing here. :shock: http://kudria.com/projects/vehicles/turbos/images/F-25...
