Depending on an engine’s configuration WorldNCI offers two systems, FAST-II and HTechnology. Engines having open blow-by or road tubes are retrofitted with the FAST-II system which is comprised of both the FASTechnology™ and HTechnology. Engines having a semi-closed crank system are retrofitted with only the HTechnology. Below are results from equipment having either one or the other "System" configuration installed and are identified by FAST-II or HTech.
