Most of these race engines are built with much wider clearances for the bearings, etc.
"Big Time" race engines of all types are completely and totally different from the high performance "M" powered engines in our M3s.
: Out of curiosity, I asked a bonofide racecar driver about oil weights, composition, and brand. Of course, the engines and applications are radically different from the typical M3 driver.
: When he drove the Lenco top alcohol dragster, they used straight 60 weight, and changed it after each 1/4 mile run.
