Crank scrapers or plate...?

Look at the oil pan gasket for a 2.4 from a SRT-4, it has as close as you can get to a crank scraper in a production type motor. this is combined with the balance shaft housing that acts like a Windage tray.

Showing a scraper from one production performance engine, doesn't say how many production engines use them. Not raggin' on ya at all; it just bugs me when broad generalizations are attempted from one example. It shows the Mopar guys still had some brains when they did the SRT4.

I thank everyone who chimed in with info; I suspect many have learned a lot. It still looks to me that most all of the examples where it is clearly obvious are concentrated on the high RPM uses... where it does indeed make the most sense (to me at least).

And where you are racing, every improvement can/will show up; I lost a position in a rally by 2 seconds out of a 4 hour stage total time; I bet that scraper would have made up that difference and more. But, on the other hand, a $3k set of rally shocks would have made an improvement of 2 MINUTES... or more. Guess what I would save up my $$ for.... We ALL make cost/benefit choices all the time. I like to see sharing of the info, and letting folks decide.
