ProCharger Truck/SUV Editorial

With the engine built to be blown, our low-compression 540 made 507 hp at 4,800 rpm and 606 lb-ft of torque at 3,200 rpm. Fully intercooled and boost set on kill, those numbers jumped to 913 hp at 5,800 rpm, with 903 lb-ft of torque at 4,800. The difference with the ATI ProCharger is huge, to say the least. Those numbers represent an increase of a solid 80 percent in horsepower and 49 percent in torque. That’s a ridiculous increase that would make your “seat of the pants” feel like a NASA space shutte launch!

“When put into the [supercharger] system, an intercooler brings the air temp back down, thus increasing its density and removing the need to retard the timing. Reliable power gains go from 25-45 percent with a supercharger alone to 60-75* percent with an intercooler.”

“Any time that you compress air, like with a supercharger, that creates heat, and heat is the enemy of horsepower. An air-to-air intercooler takes that hot blast of air and cools it down. This [Intercooled ProCharger system] will give you a 65% increase in power [with 8.5 psi]. That’s more than any other supercharger on the market.

"Compressed air gets hot, but diverting it through the intercooler cools it down before it gets to the throttle-body."

"A [chassis] dyno run demonstrated a maximum of 377.8 rwhp and 357.9 lb-ft of torque." (66% power gain, stock '02 5.3L Tahoe)

“These intercooled ProCharger systems provide reliable 60-90 percent gains* in horsepower and torque on pump gas, with significantly better engine reliability than is possible when supercharging without an intercooler.”

"The mildly modded 5.4 (2004 3V) received a ProCharger P-1SC centrifugal supercharger along with its air-to-air intercooler. The GMS crew reflashed the computer with Superchips Custom Tuning software, and the 5.4-liter SOHC motor now makes 420 rwhp and 410 lb-ft of torque."

“The driveability of the system was tested when we loaded down the truck with a 7,000-pound boat and trailer and a bed full of weekend boating gear, and traveled a couple of hundred miles over hilly highway toward The Lake of the Ozarks in humid 85-degree weather. Even under boost conditions, as the truck effortlessly pulled the weight up long hills for long periods of time, the engine’s coolant temperature never surpassed normal operating temperatures.” “Because of the extraordinary efficiency of both the ProCharger and intercooler systems, intercooled ProCharger systems feature the coolest intake temperature of any supercharger.”

“Intercooled supercharging results in less stress on engine parts, lower engine temperatures, and better fuel mileage.”

By using an air-to-air system, more boost can be applied to the motor without fear of detonation or the need for added fuel enrichment systems or ignition retarding.”

“In addition to denser air and full ignition timing, there is considerably less parasitic loss...”

Truckin'

 

 

“What cuts down on a charger’s efficiency is a byproduct of compressing air - heat. When the air is compressed, it gets hotter. And the hotter it gets the less dense it becomes. You will still see power gains but the ignition timing has to be pulled back about 1 degree per pound of boost to keep the engine from detonating or pinging.”

“The intercooler (like a radiator for the air) brings the temp back down to around 20 degrees above the outside air temp.”

Sport Truck

 

 

“That’s a 2.33-second gain in the quarter-mile [with a stock 5.7 TBI] on pump fuel without sacrificing any driveability.”
