In this episode, Lake Speed Jr pays a visit to EFI University where the Expo engine was torn down and has been sitting for two months. Profilometer in hand, Lake shows how much corrosion from oxygenated fuels can alter the surface finish of cylinder walls and why that’s a bad thing.
For the second half of the segment, Lake heads back to the studio to join Expo host Joe Castello and NHRA champion engine builder Gary Stinnett to talk about proper engine prep techniques to prevent corrosion and how that led him to develop a fogging spray, Foggit.
