Forced-Induction Parts Buyer’s Guide - Modified Magazine

There’s more to consider when upgrading a factory forced-induction setup than merely slapping on a bigger turbo or new supercharger pulley. The setup must work as a whole, and this theory applies equally (if not more so) to boosting a NA powerplant as well. Before you spend your life savings on eBay, take a look at some of the best FI parts available on the market today and choose wisely.

HKS
GT Supercharger
HKS’ latest forced-induction system, the GT Supercharger, is a newly developed “torque reaction drive type” centrifugal supercharger. A centrifugal-type charger was selected, as it carries many advantages such as low noise, light weight, and compact design. The traction-drive system further reduces noise over traditional overdrive gear systems. Because the overdrive ratio can be increased with this system, the compressor size can be reduced, and as a result, a compact unit is possible. Torque-reaction-type systems apply pressure in proportion to transfer torque, making the unit durable and efficient under low load conditions. This in turn delivers good fuel consumption for an economical and environmentally efficient forced-induction system.
