Check this out! Have a garage and hand tools? Bolt on 134 hp to your late-model Gen III "Eagle" Hemi in just five hours with ProCharger's DIY-friendly supercharger system.

Hemi Power Play - ProCharger's Supercharger System

... There is no replacement for displacement, but forced induction can sure help level the playing field. So with that in mind, ProCharger decided to turn their attention to the smallest modern Hemi: the 5.7L "Eagle," designating the '09-up version of the engine that makes 370 hp from the factory. Currently, ProCharger already has kits available for SRT 6.4L and 6.1L cars, but the lion's share of modern V-8 Challengers are packing the 5.7. Essentially, you can go out and find a bargain on a '09-14 5.7L Hemi car, load it up with a ProCharger kit, and run down the bigger engines with ease.

Of course, the kit itself has a price, but if you're handy with a wrench you may be able to forgo the install charge since ProCharger went to great lengths to ensure the design of the kit was very enthusiast friendly. That means you don't have to be a professional mechanic; you just need to know your way around an engine bay, have a space with tools, and be able to follow step-by-step instructions. Think we're exaggerating? OK, we'll prove it.

We do love showing you how the professionals handle installs in their shops, but for this install, ProCharger had one guy take their '10 Challenger R/T home for the weekend and tackle everything on his own in a standard two-car garage with only standard handtools. No pro support, no labor rates, just one dude bonding with his car bolting on affordable blown power. Assuming you have your tools laid out and dive right in, you could be up and running with over 500 hp at the crank in about five hours. Just try and tell us that doesn't sound appealing. ...

Wow, if I didn't have the extended lifetime warranty I would be seriously thinking about this. Heck I am thinking about it even with the warranty!

Yep Pro Charger has a good rep for making power with these modern Hemi motors. :smileup:

That's a great article! Thanks for posting, RichR!

glad to see another iowan on the board.
let me know how it goes

Good to see you here, too. Where are you from?

Compared to stock, it goes like a bat outta hell!

Before: 341 RWHP @ 5200 RPM, 362 lb ft @ 4300.
After (max 6.8 lbs.): 448+ RWHP @ 5993+ RPM, 416 lb ft @ 5300.

FWIW, although the ProCharger website appears to be silent on the matter, I've heard it said that this or any other modification doesn't in itself void any warranty. That, in order to legally deny a warranty claim, they must prove the failure was caused by the modification.

Might be worth calling an attorney (or, the Handel On The Law radio show).

Adds 134 HP? Not quite a Hell Cat, just a shade below...

Purgatory Cat?

Bolt on a supercharger in just 5 hours? No way! I'm pretty sure it would take me more like 5 days haha! That's pretty cool though, they make it look easy. Maybe one day down the road I'll give it a shot!

The Procharger kit itself isn't all that expensive compared to other superchargers. I think it's around $5,700 or so isn't it?

Not being too familiar with centrifugal and roots supercharging other than what I have read on this forum and other sites, I'm assuming that you kept the stock camshafts and pistons as opposed to replacing them with forged steel parts? In that scenario, does the max 6.8 lb boost limit the potential damage to your stock engine components?

 

[cdahl383]

I think more boost creates more heat in the cylinders and some of the stock parts aren't up for it. Think it damages the piston top ringlands or something.

That seems to be consistent with what the article states: Thanks to the highly efficient air-to-air intercooler design, the kit can make more power with less boost and heat.

On a 5.7 motor you should have no issues. On an SRT motors they are more brittle and you takes your chances (ringland issue Carl mention is the culprit)

 

[HemiMetal]

Thanks Andres (and Carl)

I didn't know about the SRT engines being more susceptible to this kind of damage.

Good looking out!

You are correct. The ProCharger engineer said 7 lbs provides a good safety margin and is as high as they'd go with the stock internals. Forged pistons would be next.

 

[cdahl383]

Don't they also recommend lower compression for higher boost applications? I think our 5.7L's have 10.3:1 compression don't they? I know my cousin's Mustang has 8.5:1 compression and he runs 12 lbs of boost with his Vortech. Maybe the newer engines are different?

 

[us1champ]

yes lower compression is wanted on supercharged cars.
i have a blower on a 6.1 i am at 8 lbs.. won't go any more and it bothers me without having pistons.

i also see some talking about stock pistons in the 6.1 vs 5.7
it is a trade.
the 5.7 does not have a forged crank, the 6.1 and 6.4 does.. so there are trades for all. i don't believe ( i could be wrong ) the rods are as good in the 5.7 either.

most say for a super charged car to be around 10.0 to 1 or a little lower.. depends on valve train also.

one key to a blower car is the tune. the tunes that you get from procharger, magnuson ect arn't very good. canned tunes are generic.. they was developed on car x y and z.

your car may not react the same.. may have more knock. may have different throttle body. different exhaust, ect ect ect..

i guess my point is. if you want a supercharger, or have one. i would HIGHLY reccomend someone doing a custom tune vs using what comes with the kit.

and i have learned the hard way that some tuners are more through than others.

the tunes that you get from procharger, magnuson ect arn't very good. canned tunes are generic.. they was developed on car x y and z.

In order to make their kits, ATI ProCharger does one complete beta installation for each model, engine, year and transmission. (Mine was the one they used for the 2011 Challenger 5.7L w/6-speed. This was only two months ago.)

They only recently began development on the 2011-and-newer models, after the 2011+ OEM tune was successfully reverse-engineered.

So, if someone bought a ProCharger kit for a pre-2011 Challenger and installed it on a newer one, the kit tune would be wrong, simply because it's for a different car.
