The short turn is critical to peak flow. It's not uncommon for a port to hardly gain anything in high-lift flow until the short turn is worked, with the tendency being to stall at a certain max flow level. This intake shortside was cleaned-up as shown in the port at the left, netting about 10percent in peak flow. Note the rounded, laid-back shape. On the right is the raw shortside before porting.
