Crank scraper
SOHC 4G63 came in the 89-92 Galant. I pulled a motor myself to check it out and compare it to the G63B and 4G63t 1g of the same vintage.
A retired Chrysler engineer who worked on the 2.2 Shelby Charger engines reported that Chrysler and Mobil did joint research back in the mid 1980s on windage losses for that engine. (This is the gentleman who made aftermarket racing oil pans for several years for the Shelby racers -- no, he said that he does not want to get back into that -- I asked).
They picked up 7 hp at 6000 rpm and 9 hp with Mobil-1 using a crank scraper type windage tray. It is difficult to get this kind of info because it is circulated within the car companies but not available to the general public.
Hope that info helps!
Kind regards,
