"All in all, it's a pretty simple installation [350 MPI system].
The difference in available power was awesome. The 28' Eagle topped
out at 76.3 mph (4,950 rpm), an amazing 18.3 mph gain! And the 26'
Eagle was even a shade better... a giant 19.7 mph jump!"
Hot Boat, October 2001
The radar gun
nearly fell out of my hand. I looked at the digital display and saw
a difference of 22.4 mph from the speed run we had just made only
a couple of hours earlier...In addition to boosting performance, the
ProCharger can improve fuel economy at cruising speeds because the
engine isnt working as hard as a naturally aspirated model to
push the boat.

We
were astounded at the difference. A full gain of 20 mph had been obtained
[on a 29 Fountain with a single 502 EFI and Intercooled ProCharger
M-1 system, running pump gas] using only the ProCharger, intercooler,
and the larger propeller.
Hot Boat, April 1998,
p. 85
In addition to raising speeds across
the board, the ProCharger gave our test boat [Rinker 243 Siesta v-bottom
deck boat] a quicker hole shot. The souped-up engine [stock 7.4 MPI
with 5 psi Intercooled M-1 ProCharger] pushed to us 36 mph in 7.38
seconds, whereas the stock package took 10.28 seconds.

[The 42 Fountain with twin 502s] posted a top speed on radar of an incredible
109 mph! That meant a 31 mph gain at only 6,000 rpm with 92-octane
fuel

The ProCharger attracts a speed freak on a budget, because he
doesnt have to modify his engine below the intake manifold to
make the system work...To see that the ProCharger draws less [hp to
drive the supercharger], all you have to do is look at the belts used
on the two systems. A roots system uses a 3 or 4 wide
cog belt, while the belt on a ProCharger is maybe 1. That also
means less load on the crankshaft

I like it. Its really a good,
easy bolt on
Harry Christenson,
Advantage Boat (Powerboat, March 1998).
The ProCharger bolted on an additional
225 horsepower [to a stock carbureted 454 Magnum]. The compact ProCharger
blower...thrives with stock timing and requires no internal engine
mods, so long as the engine is healthy. We were extremely impressed
with the low-rpm characteristics shown by the ProCharger setup, as
we idled through no-wake zones and shifted at whim...

The resulting package [502 Chevrolet with an Intercooled M-3
ProCharger in 22 Stealth] was one of the hardest-accelerating
boats in the history of our tests. It shot from a rolling idle to
a 60 mile-an-hour sprint in 9.89 seconds - the quickest of all 17
boats we tested at Havasu. It was also the first to 30, 40 and 50
miles an hour, and was the fastest jet-driven, V-bottom jet boat in
the history of our annual evaluations, at 79.8 mph.
Hot Boat, February

To date weve had exceptional
performance from them. We have done better than two dozen bolt-ons
in two years, mostly all EFI. Even the oldest motor with a ProCharger
is still running today. It was recently in for upgrades, and we checked
the motor. We found no sign of internal damage and no leak-downs I
would call excessive.
Mike Petersen, Eliminator
Boats (Powerboat, July 1999)
Named Blown Sleeper, the 15,000-pound boat [Formula 400 Ss cruiser]
was clocked by radar at an un-cruiser like 66 mph. With a pair of
stock MerCruiser 502 Mag MPI engines...and a ProCharger Stage I [M-1]
system bolted to each engine...it turned more than a few heads.
Boating, March 2000,

The ATI ProCharger is a pretty cool concept.
Its relatively compact size makes for a space-saving, low-profile
installation. You dont lose the rear deck as a tanning salon.
The 20-mph conversion [28 Eliminator Eagle V-bottom with 7.4
MPI] from a plain-Jane motor to a gospel-preaching something else
is cause to celebrate.
Powerboat, July 1999,

[We] ..dynoed a 540-c.i. mild motor that
recorded 546 horsepower (unblown), and 1,167 hp (114% increase) when
the ProCharger was installed.
Hot Boat, August 2000,
p. 26
While most roots-type blowers generate
added temperatures to the motor in the area of 250 degrees above ambient
temperatures, the motor we tested (1,167 mp 540 c.i. with an M-4 Intercooled
ProCharger) only produced 23 degrees above ambient temperatures at
peak. Almost as impressive is the fact that the motor idles at 850
rpm, where most 800-plus hp motors want to idle at 1,200-plus rpm,
which makes it difficult to shift into gear around docks and loading,
etc.
Hot Boat, March 2000,
p. 132
We also like that at 3500 rpm, the ProCharger
pushed us to a cruising speed of 43.2 mph [in a Rinker 243 Siesta
with 7.4 MPI] versus 38.4 mph with the stock engine. Needing fewer
rpm to run at the same speeds means longer engine life and less wear.

While the 257 Effect Open Bows top
speed was astounding - weve never gone faster in a bow rider
- it was far from the most impressive aspect of the boats performance
[fuel-injected 540 c.i. with Intercooled M-3 ProCharger]. Acceleration,
both standing-start and mid-range, was the real eye-popper. Time to
plane was 3.7 seconds, and in 15 seconds, the cat reached 88 mph.
The boat was ballistic in the mid-range, going from 30 to 50 mph in
2.7 seconds, 40 to 60 mph in 2.9 seconds, and 40 to 70 mph in 4.6
seconds.
