The single biggest accessory for a supercharged application on the street is an intercooler. Strategically mounted, it will considerably lower the air intake temperature, increasing the density of the air/fuel mix for bigger power gains. Since our engine will be static on the dyno, the boys at ATI sent along this water-to-air intercooler (used on boats) so that we can keep the intake charge as cool as possible. It bolted on to our special-made bracket. Neat setup!
