Triumph TR8 Efi Upgrade Kit
For larger capacity (4.6 litre and above) Performance engines using the original fuel injection system, considerable gains in torque and horsepower are attainable by fitting an Efi Upgrade Kit. Kits are available for both Flap-type and Hotwire efi systems and comprise a ported and enlarged inlet manifold (inlet tracts opened out to 45mm diameter), trumpet base with enlarged (45mm diameter) intake trumpets and plenum chamber with enlarged (72mm diameter) throttle body. These componenets help to remove the restriction in air flow, which can strangle your enginge's power potential. Efi Upgrade Kits are sold on an exchange basis.
