Optima Redtop Battery vs. Yellowtop Battery: What's the Difference?

Before spending big on a new AGM battery, you’ll want to know the difference between the Optima Redtop and Yellowtop. We break it down for you.
On episode 26 of Engine Masters, find out if you can stuff 25 psi of boost into a cast-piston, stock-crank short-block and have it live! Watch as David Freiburger, Steve Dulcich, and Steve Brule strap a ProCharger centrifugal supercharger to a bone-stock Chevy 350 bottom end and keep stepping up the boost to find the breaking point. But there’s a hitch: They agreed they would let the engine live if it could make 750 hp and survive. So did the guys leave parts on the floor, or did they make stupid power with a foolish combo? They did the best they could to show you blow-through boost tuning by keeping the ignition timing and the air/fuel ratio very conservative while also using Rockett Brand 118-octane fuel to prevent detonation.
