What Ken Smiley is running right now: V-Flo ($350),
Capristo ($5k for full version), and ECU flash ($800). He also de-snorked, which might have an effect. The
IPD intake
plenum will interact synergistically with these mods, as will the accessory underdrive pulley. Do them all and your power:weight will beat a Carrera S's. But remember, your engine and brakes would then be dumping heat faster than before, so you want to bulk up there. So do third radiator and GT3-style air passage. And for a while I've been promoting brake fluid recirculators (in addition to high perf fluid and braided stainless lines), because I intend to do it and I want someone else to be the guinea pig
