What are the pros and cons to both of these two systems? Just from reading different posts on here about the STS system appears to be putting out more HP and TQ than the procharger but it also looks like the procharger wont be as harsh on the engine and requires less engine modification than the STS System. So can anyone tellme what the good points and down sides of both systems would be? Im getting my refund check and mid year bonus this month and I want to get a few things done to the truck. Any information would be great guys. Thanks

 

The turbo will make more power.

There is no need to do any motor work with either if you keep the boost reasonable.

The procharger uses auxiliary injectors in a throttle body plate. Our intake manifolds are not designed for that so the fuel mixture will not be equal into all cylinders.

STS does not offer a tuning solution because of that issue, so its up to the buyer to provide tuning.

The tuner of choice with the turbo guys today is the SCTflash.

They are both about the same as far as harshness on the motor. They both spool up with revs.

The STS is easier to install and costs less.

 

actually from what I have found is that they basically cost the same... and I too have been contemplating the differences between the 2. And so far I have been unable to come to the conclusion over which is the better of the 2. In some cases having a turbo hanging underneath your truck where your muffler is could be a problem but at the same time helps keep some of the heat out from under the hood. The ProCharger doesnt require having to tap into the oiling system since its a self contained unit and although it is basically designed to work similar to a turbo all be it driven by a belt instead of hot exhaust gas, the same setuprobs power directly from the get go from the engine. And as for the tuning part its tough since practically every programmer or chip/flash setup has known issues with warranty and could possibly require a tow back to a dealership to have your computer set back to factory when/if it locks up on you, its the luck of the draw on that. Plus without rebuilding you will have to keep the boost levels to the standard 6-7 lbs. or less just to be safe.

Luckily with the current price of gas, my truck spends about 25 days a month in the garage while I drive a Lesabre or my Neon so the quest for more power out of the HEMI is getting set further back to the future.

 

This is straight off the procharger web page:

The Most Power and Best Performance
Intercooled ProCharger systems deliver the ultimate performance and power increase for towing, daily driving and sport truck applications. Compared to all bolt-on aftermarket superchargers, ATI's superior technology delivers more low-end torque and substantially more total power than any other supercharger system. In the lower rpm towing range, Intercooled ProCharger systems will deliver more rear-wheel torque because the intercooled charge air is extremely dense (virtually at ambient temperature), the engine is running full timing, and the P-1SC consumes far less power than positive displacement superchargers. At mid-range and higher rpm, in addition to making more power per pound of boost (due to the same combination of greater air density, full timing and less parasitic load), an Intercooled ProCharger system is also able to safely produce more total boost, thanks to the coolest charge air and exhaust gas temperatures in the industry. The net effect is a substantially larger increase in air density, which in turn produces a substantially larger increase in power. History and physics show that applications without intercooling must run unsafe boost levels or octane-boosted fuel to perform even close to an Intercooled ProCharger system.

Superior Efficiency and Fuel Economy Intercooled ProCharger supercharger systems enable your truck or sport utility to deliver unparalleled performance without sacrificing daily drivability or gas mileage. In fact, unlike inefficient positive displacement superchargers, in most towing applications your gas mileage may actually increase slightly thanks to the superior efficiency of the P-1SC ProCharger. Stock or modified, for towing, daily driving, or racing, Intercooled ProCharger systems deliver far more performance with far greater engine reliability than any other supercharger system or power adder such as nitrous oxide.

The Best Engine Reliability and Drivability
ATI introduced the industry's first intercooled supercharger system nearly 3 years before its nearest competitor, and is the only company that offers air-to-air intercooled supercharger systems for trucks and SUV's. Other companies' non-intercooled and air-to water supercharger systems are typically tuned at the edge of detonation, which leaves you little margin for error. However, because air-to air intercooling removes the heat which causes detonation, you can safely run far more engine-friendly intercooled boost with full timing and complete peace of mind. With air-to-air intercooling, there is no need for "band aids" such as ignition retard, over-rich or auxiliary fuel injectors, or water injection. There is also no need to buy exhaust gas temperature (EGT) gauges because intercooling means that exhaust and overall engine temperatures remain stable even during extreme towing, racing and/or summer heat conditions. The intercooler system, which is standard equipment, simply rejects far more heat than it will receive from the highly efficient P-1SC ProCharger. Intercooling is clearly the fundamental solution for reliable high performance, because it substantially improves both engine reliability and power output. That is why intercooled forced induction is the high performance technology of choice for millions of factory OEM vehicles worldwide.


I know the turbo is going to make more power but this system just sounds like it would be a little better than the turbo set up, It is a 6psi with a 3 core intercooler, all of their results show a min of 100hp gain at the rear wheels which is less than the sts, anyway I ordered a catalog from both places and sent them both emails so we'll see....

 

A little more info from their web page:


ATI is proud to announce its HO Intercooled ProCharger system for Dodge Hemi 5.7 Rams. The system produces 45-50% power gains on stock motors running pump gas with 6 psi of intercooled boost. Featuring the coolest charge air temperatures available, the ProCharged system delivers industry leading power gains and superior engine longevity.

Industry exclusive features include a 3-core air-to-air intercooler system, and patented self-contained supercharger with 3-year warranty. The HO Intercooled ProCharger system is 100% complete, with supplemental injectors and programming to ensure maximum performance.

ProCharger systems feature easy installation, minimal relocation of components, no need to punch a hole in the oil pan, and avoid having to deal with all the complexity of an air-to-water intercooler.

Hemi Ram systems are now shipping. Additionally, an Intercooled ProCharger system for the 5.7 Charger is also be available. Hemi systems for the Dodge Magnum, Chrysler 300 and 6.1 liter motors will be available in late 2007.


From the sound of it it comes with the programing as well....

 

if this is going to be your daily driver, you probably want to go with the STS. if you take it to the track often or do hard off roading, go with the procharger. the sts may give you more power but the pc will give you more low end torque, and power all the way through the band.

if its a daily driver you're better off with the turbo cuz it will only kick in when you want it to based on the load on the engine. the procharger will always be sucking hp even when you don't need it (wasted fuel, unnecessary wear on motor). i really feel the decision is totally dependant on your application. both look like solid kits to me, and the price is comperable, though you do have to pay extra for tune with STS i believe.

also, if you get the sts, you get a relocation kit for the intake. it gets tucked up between the inside and outside of the bed i think, so it won't be sucking in dirt and such.

 

You can tow with the Procharger but not with the STS turbo because the exhaust gas temps go through the roof. So if you do any towing take this into consideration.

 

STS dealers sell the kits for a lot less than the price on the sts website.

M15 is right on. Turbos on gasoline engines are no good for towing.

Centrifical superchargers make boost with rpm's.

Turbos make boost with heat and load. A turbo can make boost under 2000 rpm on an uphill incline in a high gear.

When boost goes up, EGT's go up.

 

good call, had never thought of that. you'd be making boost you don't want or need.

 

Ya STS turbo all the way if not towing but check out what I found on KRC's web site.
Procharger Intercooled system using the KRC 2 bar map sensor/ 50lb injectors (qty 8), SMT6 Standalone programmable system. $5499
[ul][*]No aux intake injectors to run the front cylinders lean, 8 injectors to to get the job done right. Only 8 wires to connect. Air to Air intercooler. D1SC upgrade available too for built engines. [/ul]
