Should I Use A Mini Or Offset Starter?


What Is A Windage Tray?
Windage is the flow of air within the crankcase. Each time a piston comes down in the cylinder bore the air under it is pushed into the crank area and each time the piston goes up the air is being pulled behind it. At the same time the rotating assembly is spinning and churning the air and adding oil into the mix. The windage tray keeps the windage around the crank from the oil in the sump area. It allows the oil coming off the crank to easily enter the sump without the windage affecting the scavenging of oil already in the sump. The windage tray also keeps any oil in the sump from getting into the rotating assembly during vehicle motion.

What Is The Proper Clearance Needed Between The Oil Pickup And Oil Pan?
You can calculate the clearance by measuring the internal pan depth and measuring the distance from the block's pan rails to pickup bottom. The difference between the two measurements will provide the pickup to pan clearance. Gaskets will add some additional clearance. Here are some recommended pickup to pan clearances: Ford Pans- 5/16-3/8 inch (.312-.375) Chevy Pans- 5/16-3/8 inch (.312-.375) All Others 5/16-3/8 inch (.312-.375). Deep sump pan pickups are submerged deeper into the oil are less sensitive to clearances. Deep sumps may have clearance up to a 1/2 inch.

Should I Use A Mini Or Offset Starter?
These starters use a smaller and faster motor combined with gear reduction to produce increased cranking power in a package that is lighter than a conventional starter or OEM starter. In addition, they are offset to provide more clearance for the horsepower saving oil recovery pouch on our power pans. To determine what starter is best for your application consider the needs of your engine and your oil pan. Our oil pan descriptions call out starter requirements when necessary.
