Procharger For 5.7 L Challenger Rt

I have read in a recent Mopar Power magazine that Procharger has a great DIY unit for us 5.7 litre folks looking for some more oomph. Has anybody out there installed one and if so, is it as good as they say?

 

You can actually call Pro charger and they will send you a Hemi brochure on their superchargers for free. I just got one last week, thing is their superchargers intercooler works on air not coolant.

 

Looks like the Pro Charger is a Turbo set up. Not an application I would go with on a domestic big block. I have a Supra with a Turbo Application which works fine, because the block was build for the pressure. The big issue with that application was number 6 cylinder at the back of the in-line 6 always blew the head gasket. To much heat and pressure. Another concern is limited space under the hood. In-line 6 has the room on either side, hence why Toyota also came out with the Twin -Turbo on the 4th generation Supra. Just my two cents worth.

 

Procharger is a centrifugal Supercharger. Basically a belt driven turbo if you boil it down. Also why the Air to Air intercooler works. Most of your water to air intercooled applications are on a roots style blower.

 

I tell guys that want a cheap fix in hp is nitrous. Kits are getting cheaper but so much safer from blowing up the engine. On a stock 5.7 look at the 60-75-100 hp shots. You can google to see you has the best units out there and yes spend a few hundred more for the best.

 

I wonder how much tuning is required.

 

With a Procharger kit at 8 lbs. boost, you'll be right under 500 rwhp and 500 lb/ft torque. Tuning will be critical, and you may have part throttle boost issues, like leaning out of the fuel mixture under part throttle boost conditions. This can cause detonation inside the engine, raise cylinder pressure and heat tremendously, and blow a ring land off a piston or worse. Some also experience "auto- drive" under part throttle boost, where boost low pressure boost is happening at part throttle, and causes the car to feel like it is still accelerating when you are actually pulling your foot out of the throttle.

Chrysler computers 2014 and earlier have no way to sense and do anything about boost pressure from a power adder like supercharger or turbo, so custom tuners have found ways to "trick" the computer into performing. Full throttle performance is not much problem, part throttle performance can be - you may need to learn to "drive around" part throttle conditions.

Suoerchargers are great fun - just read and educate yourself so you'll understand what the trade-offs are...

 

I've installed a magna charger on my 2010 challenger. With a good tune from someone who knows what there doing there isn't any real issues to work around. I am running 8 pounds of boost with no problems. I'm also running water methanol injection, it greatly reduces the chance of detonation.

 

I have a Procharger on my 2010 R/T ...not aware of any tradeoffs and it is my daily driver.

 

There are a lot of supercharger options, ProCharger and Vortech are centrifugal style then there's the twinscrews, Kenne Bell, Magnacharger, Edelbroch, and now Whipple and I probably missed a couple. There's no way I'd run one without dynotuning much safer and you'll get more out of it.

 

I have a vortec with a air to liquid innercooler. We have built a ice box/pump system that mounts in the trunk under the floor in the spare tire area. It works very well. The vortec however, is maxed out at 15 lbs boost, and doesn't have enough velocity at upper rpm to carry full boost in the top gears, so it does drop to about 10lbs. Going to install a Kenne bell 4.2 to get rid of that issue. All in all, still have posted 11.30's on the board with 1.6 60' times, with the 6 speed.
I like the air to liquid innercooler better than air to air, disspite having to dump ice in every pass. Even on hot days it seems to keep times more consistant through the whole day.

 

Back to the tuning, I've gotten better results data logging then dyno tuning. Dyno tuning doesn't give you the real world data for the car. You can run flat out on the dyno but there isn't true load on the car. You need the data you get from driving your car on a regular basis . Roller dyno's are also hard on your car , more on manual then automatic.

 

I hope that Dodge jumps into after market products that will keep your warranty intact. Right now they have the Scat Pack which looks to add 38 total additional HP. The problem is the cost. I can not get a number from dealers but I ballpark the full package to cost over $12,000. Mustangs are already being improved several speed specialists that can be ordered at the dealer under full warranty. Mustangs and Camaros in 2015 are available from the dealer with performance close to the Hellcat.

Help us that bought before the Hellcat became available. Turbo, Supercharged, I do not care. Just get me close to 500HP at a reasonable price and I'M in!

 

I have installed a ProCharger and also have a 75 shot of nitrous. The dyno numbers (DynoJet) 466.73 WHP/467.60WTQ with just the Pro Charger, with the nitrous 537.30 WHP/627.14 WTQ. The car ran a 12.03 at Lebanon Valley.

 

Don't forget that the 5.7's have hypereutectic pistons, and should be changed to forged Pistons, when Supercharging, Turbo Charging or adding Nitrous. The current Pistons are silicon infused aluminum alloy, and under high pressure and heat for long periods, will experience catastrophic failure. That said, there is no hard and fast formula for figuring the failure. 10,000 hard miles? Who knows... Just be prepared for a rebuild sooner, rather than later if you don't do the upgrade. And the degree of rebuild will vary by how hard the engine fails. Pooled silicon on the top of the piston? Could be valves, heads, rods, etc. Worse failure? Crank, block, etc...

 

All good to know. I'm debating pro charger vs nos still not sure. I've got a 5.7 ram rt I've got a couple of mods but would like to get up to around 500 to 550.

 

The hyper Pistons are not as week as most think. The real problem is the ring land location. Chrysler designed the ring land to close to the top. Keith Black has hyper Pistons and what he did was moved the ring lands down. Granted they are not as strong as forged piston, but if you take care they last a while. The thing that needs to be taken care of is the detonation problem that can happen with forced induction. Running 6 to 10 pounds can be done safely if you take care . You need a good tune by someone who knows what they are doing, drop one heat range on spark plugs and get your intake charge as cool as you can. (Water methanol injection works well for this) and yes it works on root style superchargers. With a proper setup it will run fine for quite awhile. A friend of mine has been running a root style supercharger on his 2009 R/T for 50,000+ miles now with no problems. He took care and adressed the problems before they became real problems.

 

I am running colder plugs and a custom tune. The nitrous is controlled by a window switch to spray at > 2800RPMs at WOT.
