I really appreciate your posts, @R Vosari, because you say what you think and have a different perspective. I appreciate anybody who treats these cars like sportscars, rather than investments.
To my knowledge, I was the first guy on this site to dry sump my car. Indeed, I had difficulty finding anybody who wanted to talk about it back in 2008 or so when I did it. I hear what you are saying regarding the power increase, but regardless - to my way of thinking, sportscars are dry-sumped because every engine needs oil, and the main benefit to dry-sumping is to ensure you're going to get it. It's nice to have no oil sloshing around the bottom of the case, but the larger benefit is being able to run the car as low as possible - much lower than is prudent with a wet-sump system, and to always have oil.
I think there's a power benefit, but with an oiling system as bad as the Type 1's, dry-sumping fixes most of it by making sure the things that need oil always gets it.
As for the windage-tray - almost everybody I know in the ACVW hobby hates them, but I've always run one in my wet-sump T1 engines.
What the V8 drag-car guys do has almost no correlation to our cars. All of the big-power VW drag guys run multi-stage dry-sumps.
Again - I always appreciate your input, but I'll be over here doing my thing.
