This is the crankshaft we use in our Pro Drag SR20 engines making over 2000+hp.  This crank was specifically designed for this application for strength and durability.  The factory stroke allows us to have a better rod ratio for reduced piston scuffing at high boost and a larger connecting rod for strength.  We also implemented the direct oil holes for the connecting rods.  With increased boost comes increase vibrations in a 4 cylinder.  So we increased the flywheel bolts size to 1/2-20 so we can use Top Fuel L19 flyhweel bolts.
