As you can see, without a compression tool, it would be pretty
tough to get the spider tightened down properly.
FEATURES & INSTALLATION
Our kit included a GBoost
Once we pulled the clutch, the rest
of the job was easy enough using the
video and directions. You will also
need a torque wrench, or perhaps two.
Some fasteners require 10 foot-pounds
of torque, but the clutch requires 95
We broke the new belt in with 25
miles of easy driving, and we didn’t go
over half throttle. If we had to climb a
mild hill, we selected low range. We
also tried to vary the throttle inputs.
After the break-in period, we hit
one of our steep, rocky test loops. The
GBoost kit actually feels like it geared
the car lower. It takes off smoothly with
a bit more rpm. The engine consistently carried a little more rpm. Despite the
heavy car carrying tools and a spare
wheel, the Turbo climbed steep, stair-step hills with ease.
We never felt the belt get hot, and
we never smelled a hot belt, either.
There is no squealing, lurching or
vibration from the clutches or belt.
Throttle response is instant, and there
is no hesitation waiting for backshift.
There is less engine braking, but we
The engine braking feels more natural, and the switch from off-throttle
descending to back on throttle is a
much nicer transition. It does all this
with great response, despite the heavier and taller tires we are running.
GBoost’s goal is to eliminate belt
slippage, provide better backshift/
downshift, increase bottom-end torque
and be more driver-friendly at low
speeds. They also want to increase the
low-end smoothness and driveability.
We didn’t really feel any slipping when
the machine was stock, but GBoost
hit all of the other goals. The machine
feels energetic and lively in all cases.
The kit is $299.95, but at least $120 of
that will be the price of the new belt.
All of the parts are high quality and fit
exactly like they should. For information, the website is
Taking apart the driven clutch is easy. You need a Torx bit, and you will need blue
thread-locking compound for assembly.
