interested in learning more about diesel performance

Does anyone have good links to learn about older diesel Benzes on the interwebs?

Also, any more news on the GRM beetle TDI project car?

What sort of benz are you working on?

The info goes basically like this: more fuel, more air. I just picked up an OM617 core that we're going to rebuild and give the more fuel/air treatment to.

I guess I would check out Benz forums, especially the diesel section. You have to really dig for some info since few people own them for a performance vehicle and the diesel power magazines are mostly for diesel trucks.

Pretty much only go to Superturbodiesel.com. A lot MB guys are all about "Mercedes designed everything PERFECT the first time, what makes you think you know better????"

Be weary of what you read. I see a lot of info that is mis-info. Stick to the basic rules of engines, remember them well.
