Vortech Civic Si
Vortech Engineering"s V-5 series blower has been on the market or some time but the Si is the first Honda Vortech has developed a full bolt-on kit for. The V-5 is compact in design and aimed at the cramped engine bays of imports. The D-Trim unit used in this kit moves 650 cfm of air and can support up to 435 horsepower. A heavy-duty version pushes 750 cfm of air-good enough for up to 525. Boost for the standard kit is 8 psi but the V5 can be spun to 15 psi (20 psi for heavy-duty units) while retaining abiatic efficiency (be sure you have fuel).
The Si kit utilizes a tube drive set-up to run the blower. The kit includes an air cleaner inlet, bypass valve, in-line fuel pump, FMU boost referenced regulator and a Vortech Aftercooler. The Aftercooler consists of a reservoir, pump, lines and heat exchange unit and its operates like an air-to-water interccoler cooling the charge air prior to the combustion chamber. The charge air is funneled through 2.75-inch piping that is available in satin or polished finish.
Our test car had a Comptech header system and APEXi exhaust installed along with the blower. The car was representative of what would normally prowl the streets. We were impressed with its steep power curve. In fact the only thing stopping the power production party was the rev limiter which kicked in at 7,900 rpm.
