Cessna R172K 'Hawk XP 210 Horsepower
Cessna R172K Hawk XP owners are flying with the 210 HP engine. The 210 horsepower conversion provides maximum
performance for the Cessna 'Hawk XP. The high performance version of the XP
has a proven reliability, kit installation is simple and no category
restrictions are placed on the airplane's original type certificate. The
modification is fully approved by the FAA for both the landplane and
seaplane versions. The STC covers Edo and PeeKay floats and the 210
horsepower is also approved by Wipaire in their AFMS. The
Hartzell Top Prop is approved by Hartzell for this 3-blade propeller
in combination with this 210 horsepower conversion.
tachometer & hour meter is available as an option on the
R172K Hawk XP. This tachometer
is approved by the FAA for installation on 210 horsepower Cessna Aircraft
Hawk 'XP as the primary instrument. Accurate in all conditions, easy
to install, provides diagnostic and performance information for the engine
and ignition system and eliminates operational and maintenance problems
related to mechanical tachometers and cables.

All of the
work for your Cessna R172K Hawk XP aircraft modification can be accomplished
by most FBO's. Installation time is approximately four to six hours. The kit
includes overhaul and new dials installed on your mechanical tachometer and manifold pressure/fuel flow
gauge, new fuel flow placard, STCs, installation manual, instructions and
FAA approved airplane flight manual supplement (AFMS). A factory new
governor and digital tach are optional. The work on gauges
include a one-year warranty. All kits are FAA parts manufacturing approval
(PMA) approved. With a digital tach or new governor parts are priced considering the exchange cores are
returned (governor and gauges) after the installation.

The Cessna R172K Hawk XP has adequate power at 195 horses.
That is why the increase to 210 horsepower causes such a dramatic
difference in takeoff performance. All of the added power is destined to
quicken acceleration. This shortens the distance from the start of the
takeoff roll to the point takeoff speed is reached. The 210 horsepower
makes the airplane sound and accelerate like a Cessna 210! Even under
severe takeoff conditions the airplane jumps off the ground with an
immediate and positive rate-of-climb.
rate-of-climb (1150 fpm @ 81 KIAS).
As with takeoff acceleration, the
additional power all goes to increase the rate-of-climb after lift off.
The initial climb after rotation is much more positive. The
rate-of-climb increase significantly reduces the time it takes to reach
cruise or ATC assigned altitude. This reduces pilot workload (less
climbing maneuvers) to reach required altitudes when crossing controlled
Less fuel burn and
shorter time to altitude.
Because the shorter takeoff and increased rate-of-climb requires less
time, this results in less fuel burn from the start of the takeoff roll
until reaching climb altitude.
At low pitch (high RPM) the propeller works like an air brake. The
power off decent rate is dramatically quicker at 2800 RPM than at 2600
RPM. This feature can be controlled simply by setting the prop control
in high RPM if a rapid or emergency decent is needed, or by setting it
at 2600 RPM for a normal decent approach.
The standard R172K Hawk XP requires constant braking to hold the taxi speed down
at engine idle. The 210 horsepower conversion changes the propeller low
pitch stop setting causing the blade to "flatten". At engine idle this
results in less forward pull by the prop. The airplane taxi's at a safe
and comfortable speed without the need to constantly ride the brakes.
Also, this reduces heating and wear on the brake pads and discs,
lowering maintenance costs.
Ability to log high
performance pilot in command time under FAR 61.31.
Because the airplane is over 200 horsepower the pilot may log his
time as high-performance according to FAR 61.31. This is very beneficial
to owners, family members or others flying the aircraft to build time
for additional ratings or career opportunities.
and emergency go-around capability.
How much difference can 15 horsepower make? A lot! The extra power
all goes to added takeoff acceleration and climb performance. You really
have to fly it to believe it, but the difference is a very significant
improvement to the R172K.

performance at a fraction of the cost.
You will receive maximum performance from your engine. The 210
horsepower is attained by removing the "D-rating" that Cessna placed on
your airplane's engine. The 210 horsepower XP has a proven reliability.
In essence, the modification makes the XP nearly identical to Cessna's "Reims
Rocket" built at the company's plant in Reims, France, and the U.S.
Military T-41B. Both of these Cessna airplanes have the full 210
horsepower capability of the IO-360 engine. Over 25 percent of all
Cessna R172K airplanes have this conversion installed.
What does Continental Motors say about the conversion?
". . . no affect on the difference in structural integrity or
airworthiness . . . Thus the IO360K should also provide excellent
operation and service with a take-off rating of 210 HP at 2800 rpm."
STC SE1436CE and SA1437CE approve the conversion of
the Cessna R172K to operate at 210 horsepower. The STC's are applicable
to the following:
- Continental IO-360-K
- Continental IO-360-KB
- Cessna R172K landplane (all)
- Cessna R172K floatplane
