Packard Performance’s supercharger creates power
no matter what rpm it’s at. With the other engine mods
and the smallest supercharger pulley, it’s putting 130
horsepower to the wheels!
This larger-than-stock Hess Motorsports radiator is
mounted behind the driver for less cab heat, has dual
cooling fans and is less likely to get mud packed in it
and overheat the machine.
expertise to perform a five-angle valve
job, which makes the engine produce
more usable power. Nic has his own
shop, Nic G Motorsports, and he performed his own head porting to allow
more flow. A Hess radiator relocation kit
mounts two fans and a larger radiator
behind the driver for increased cooling
capacity. This kit prevents heat from
entering the cab from the stock radiator
location. A full Weller Racing exhaust
system added a thrilling sound and
more potent power to this UTV.
MORE THAN JUST POWER
The YXZs have good suspension in
stock trim, especially for short-course
settings, but most racers widen their
UTVs for better stability and more
travel. This YXZ uses Lonestar Racing’s
MTS suspension that widens the stance
from the stock 64 inches to 71 inches.
Summer Brothers extended axles were
used since the stock axles won’t work
any longer. STV handled the billet
tie-rod kit. This setup doesn’t change
the overall wheelbase, so the YXZ still
handles properly. Another reason this
YXZ stays planted so well is because of
Double E Racing’s adjustable rear sway
bar kit. This is a better setup than stock.
It sits higher, is adjustable, stronger and
resembles that of a TT quad sway bar.
Helping the UTV hook up is a set
of 27-inch Kanati Mongrel tires. Nic
grooves select knobs off with a grooving tool to gain more traction and take
away weight. His Kanati tires are protected by TireBlocks’ flat-prevention
system, and the car sits on 14-inch
DWT Sector Zero beadlock wheels.
SAFE YE T COMFORTABLE
Nic is a big guy at 6-foot- 5, so the
stock seating arrangement doesn’t
work well for him. An NRG bucket seat
allows him to sit farther back in the car,
while the NRG quick-release steering
hub and steering wheel extend closer
to him. To meet the safety standards
of WORCS, a full race cage from STV
was added for strength and to keep the
occupant safe in case of a rollover. An
STV five-point harness also keeps the
driver safe. Bumping, but not intentionally rolling someone is legal in WORCS,
so STV front and rear bumpers were
With the jumping, whoops and hard
cornering that is in a WORCS race,
frames can become weak, so Nic welded in STV’s frame-gusset kit to help
with the stress.
We met up with Granlund at the
WORCS round at Glen Helen to check
out his supercharged YXZ before the
race. After the interior mods, the car
is comfortable for a taller driver. The
NRG seat puts the driver in a lower
position to lower the center of gravity.
Granlund’s car is a big improvement
over stock. Thanks to the Hess 2:1
steering quickener and rapid steer
kit, you can turn lock to lock without
taking your hands off the wheel. Being
that this YXZ is a manual-shifting
model, that is extremely important, as
Granlund has one hand on the wheel
most of the time.
The Kashima-coated Fox RC2
shocks work well stock , but Granlund
re-valved them so they work extremely well on a WORCS course. The car
floats effortlessly over jumps, through
chop, across whoops and over rocks.
As you can see, the seat position and the lowered
cage made for a much lower center of gravity. This
helps tremendously with the handling of the car.
Since Nic Granlund is well over 6 feet tall, he needed
more room. His NRG seat sits low and the sides are
bolstered. To accommodate him sitting farther back,
Hess Motorsports makes the longer steering quickener
and mates it with a NRG quick-release steering wheel.
