ProCharger Marine Editorial

"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!"

“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 isn’t 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”.

“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 502’s] 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 doesn’t 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. It’s really a good, easy bolt on”

“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”.

“To date we’ve 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”.

“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”.

“The ATI ProCharger is a pretty cool concept. Its relatively compact size makes for a space-saving, low-profile installation. You don’t 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”.

“[We] ..dynoed a 540-c.i. mild motor that recorded 546 horsepower (unblown), and 1,167 hp (114% increase) when the ProCharger was installed”.

“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 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”.

“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 Bow’s top speed was astounding - we’ve never gone faster in a bow rider--it was far from the most impressive aspect of the boat’s 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.
