XA.16 - 340R 340 PS/TONNE PACK (RHD: A34QX6Q07S. LHD: A34QX6Q14S^ LSL389
The purpose of the 340 ps/tonne kit is to optimise the performance potential for use on closed race tracks.
A major part of the package involves the removal of components to save weight, with the full procedure below
resulting in a dry weight of 571 kg. With a power output of 195 ps, a power/weight ratio of 340 ps/tonne is
achieved. The R H D kit includes an oil cooler fitting kit, which is factory fitted on LHD cars.

Delete air intake resonator valve: Remove the air intake resonator valve and control mechanism including the
vacuum reservoir and two solenoid valves. Re-plumb the MAP sensor. Discard the secondary air cleaner at
the airbox inlet, and connect the intake trunking directly to the airbox, with the primary air cleaner at the front
end of the trunking, which can be sited close to, or connected to the air intake duct on the LH flank. Take care
when washing, to avoid directing jet wash equipment into the intake duct - blank off if necessary.
Delete breather rail: Remove the steel breather rail from the inlet tracts. Remove breather hose from cam
cover to rail. Fit alloy blanking plugs to inlet tract spigots.
Delete charcoal canister: Remove the charcoal canister and plumbing. Vent the fuel tank breather pipe from
the roll-over valve to atmosphere.
