over the years you pick up stuff (stuff meaning you hear things) its been 20 years since I was at a well know companies show room that sells dry sump products to NASCAR teams, I found out NASCAR run vacuum pumps (i had no idea) but they also run special gaskets so they don't get sucked into the oil pan, the big question is what size vacuum pump. 98% of the info you can't use it anyways so you just build your motor best you can
Dave they even make vacuum pumps that have Roots blower type scavenge sections.. The special seals and gaskets You mention are to keep them from sucking air past those sealing surfaces.
Awesome education. I love American Muscle Culture. I have a 2022 Roadglide Special that has some Star Racing Engineering and it is Awesome. Thank you for the great content.

If I heard you correctly you are not a fan of nikasil coated aluminum cylinders. I am somewhat confused because the similar expansion factors of aluminum pistons with an aluminum cylinders nikasil coated has worked very well for me in multiple m8 engines I have built. Please let me know why you are down on nikasil coated aluminum cylinders. I am somewhat surprised. Thank you for your knowledge.
