word—awesome! The 350Z world has been begging for forced
induction since the 350 came out. We knew GReddy and Power
Enterprise were working on twin turbos, but the wait seemed
interminable. Individual small tuning shops began working
on their own turbos, and many prototypes appeared.
took the supercharger route to forced induction, and fielded
an Eaton roots-type blower. While the roots is great for huge
low-end torque for the drag racing world, the drawback is
heat, lots of heat. So heating and detonation become problematic.
Stillen does a modest 6 psi boost which ends in about 305
rear wheel horsepower.
after Stillen's supercharger hit the market, ATI fielded their
new C-2 centrifugal supercharger kit for the 350Z. Because
of the included intercooler, intake air is cooled to 20-30
degrees above ambient (compared to 90-115 degrees above ambient
with the roots blower). Running a 7psi boost, with an optional
9 psi boost pulley, the ProCharger delivers approximately
50% increase in horsepower, and the dyno charts show that
to be true with 110-120 increase in horsepower to the wheels.
Yes, it's averaging 355-365 rear wheel horsepower.
ATI kit also includes an auxilliary fuel pump and an Aeromotive
Electronic Fuel Management Unit (EFMU). The EFMU allows fuel
flow to be more accurately managed with five sliders corresponding
to various rpm ranges. Tuning should be done on a dyno with
a wideband O2 meter to measure air/fuel
ProCharger delivers an exponential increase in horsepower
and torque all the way to redline with little to no drop-off
at 6,000 rpm as characteristic of the stock dyno curves. Power
is still very linear at the throttle, you just get more horsepower
the compressor does have a whine characteristic of a jet engine,
so while that might be a detractant for some, most people
with ProChargers love the sound—it's guaranteed to turn
heads when driven through a crowded parking lot. At wide open
throttle settings above 5,000 rpm, the ProCharger simply roars
like a Force V tornado (well, that might be a bit of an overstatement).
At relaxed open highway cruising with the windows up, the
supercharger noise is only heard very faintly; not enough
to be annoying, and certainly overcome with low volume of
for the good stuff! Do you want heart pounding power for a
reasonable cost? ATI's ProCharger might be just what you're
