On this episode of Engine Masters presented by AMSOIL, we explain how oil kills power—because it's not about synthetic versus regular oil and not about a brand-to-brand comparison, but about windage and oil-pan design. We take a 700hp big-block Chevy and show you how too much oil can kill 20 hp, and you'll also see gains when we go from a stock-design pan to a Milodon drag-racing oil pan. We are thankful for Engine Masters' sponsors Permatex (for no oil leaks!), Auto Meter (to check oil pressure), Mr. Gasket (to keep the oil inside), Earls (for AN oil lines and more), and Summit Racing Equipment (where you can buy it all).

There is no hotter engine package these days than the turbocharged GM LS-Series V-8. Many people have proven that you can pull a 4.8L or 5.3L straight out of a junkyard and boost it to the moon and make 1,000 hp—but what if you're a little more conservative and want to have huge power but also reliability from an engine you can drive every day on pump gas? That's what you'll learn about on this episode of Engine Masters presented by AMSOIL. We'll show you where we spent the money and where we saved it, and why we chose some lower-power components in favor of budget and reliability as we make incredible power from a 5.3L with a single turbo, 91-octane fuel, and stock cylinder heads.
