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!"Hot Boat |
“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”.Powerboat |
“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 |
“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”.Boating |
“[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”Hot Boat |
“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”Powerboat |
“I like it. It’s really a good, easy bolt on”Powerboat |
“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...”Hot Boat |
“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 |
“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”.Powerboat |
“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 |
“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”.Powerboat |
“[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 |
“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”.Hot Boat |
“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”.Boating |
“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.Powerboat |
