Procharger install

[VPRPWRD]

Has anyone here installed a Procharger on a 13-14 Hemi? How long did the install take? What do you like / dislike about it? Any reason I should point my customer in a different direction?

Any and all feedback welcome, even the negative stuff.

The latest issue of I believe 'Truck'in' magazine??? On stands right now, has a step by step article of a procharger install on a 13-14 Ram.

Both the 6 & 8 spd trans are too weak under boost.

 

[WhiteSport]

yeah i also saw the article in truckin. that one had a 6sp. i think the 8sp would do alright but we all know the 6sp have issues for sure.

 

[VPRPWRD]

This truck is an 8 speed.

There is a Russian gent here who recently tried his luck with boost and the 8 spd.

I think his name is Badik or something to that effect. Anyways, it didnt go well and his trans was roasted in no time flat.

I pulled up a recent thread of his, right here:

It looks like he never actually pulled the trigger on a blower, still debating.

I've done an intense procharger install on my '09 and been around a few '13s with both 6- and 8-speeds and we've picked them over pretty good. Keep boost below 7psi and you won't have any issues with either transmission and since the one you're looking at is an 8- then you don't have to teach the owner how to drive it properly. The installation is a breeze on the Procharger kits, especially if you get the full kit, not the tuner. You can easily do the entire install in an 8hr day with basic hand tools. The A2A cooler makes the install super easy as there isn't a separate cooling system to plumb in. The one thing I will recommend for every blower install is to remove the factory clutch fan permanently because it makes working on the engine SOOOOO much easier.

Both the 6 & 8 spd trans are too weak under boost.

As I said in his thread, I have 3 other blown '13 Rams around where I live and neither have had issues with the 8 speed, badvik had his issues and we can't really figured out why his failed; lets face it the translation is horrible and you can't get any real technical info about the trans from him as he's not the one working on it. We have had one 8-speed failure but it was from a bad tailshaft casting, nothing internal.

In the Truckin article they kept it pretty tame HP wise, a nice solid gain across the whole rpm range, but they kept it on the drivable side and not to gernade stock parts.

I'll grab the Truckin' and take a look. Thanks for the input so far.

Where's your proof on the 8spd?

It's rated for 516lbft, which is just a hair over what the procharger kit should make at the crank.

The 6spd certainly is, that's very well known. But I strongly disagree that the 8spd won't hold up, especially with a Centrifugal supercharger.

I do believe the 516 is not rated at the wheels, I would hope a blower would add more than 116 ft/tq which would ultimately put it over it's peak rating. A fully bolted and tuned 5.7 will get you close to that max rating. I'm all about more power but when you're potentially playing roulette with a 45k truck I'm not interested lol

Your hemi does not put 400 to the wheels. Sorry to burst your bubble. 395/410 are crank figures.

Procharger quotes their kit at ~130hp gain. They do not quote torque gains.

The other issue is that ZF uses a 'torque handling' rating, not 'input torque' like other mfg's. I am not able to find a true input torque figure. However, from what we already know from our buddys with the SRTs, the transmissions will self limit via the TCU requesting a fuel cut when the torque level is approached. The 6spds do not have that technology. Which is to say throw whatever blower you want at it, if you don't tune the TCU's torque limit, it'll just never allow it to get that high.

Read my post over again, I asked if the 516 rating was crank which I assume it is. In which case my post is valid, pro charger claims 45% increase so let's assume a stock ram will Dyno at a modest 280whp/300tq = roughly 406whp/435tq which would put you over the 516 tq rating if that number is crank...

Where is your proof it wont light up?

Procharger does not claim 45%. They claim 130+hp, but say nothing about torque.

In their R&D article, they say the following:

With gains of 100 to 150+ rear wheel horsepower on stock vehicles and even more on modified applications we are sure to have a full system or tuner kit to get you the horsepower you want.

HEMI Systems R & D

Assuming a 15% drivetrain loss, 410tq at the crank is 348 at the wheel. 395hp is 335.

Let's take their 130hp number and run it through that calculation.

That would mean you go from 335hp to 465hp at the wheel, and accounting for drivetrain loss, you'd be at 547hp at the crank, or roughly a 38% increase.

Take a generous 40% increase on the tq. number, you'd go from 348 at the wheel to 487 at the crank, still 30 lbft under the rating.

The 516 is actually torque, not horse power. You can make 550chp but only 500ft-lb depending on the setup. The basic Procharger setup only pushes 6-7psi which gives an average gain of 120-130hp and 110-120ft-lb which as you can see will keep it very close but not over the handling torque of the 8-speed. Luckily the 8-speed is more efficient than the 6-speed so you get more of that to the wheels and the 8-speeds that I've seen are putting 470-480hp to the wheels.

Three '13 trucks living within 10 minutes of me that I've had my head/hands in and have been driving since the blower packages came available. The two 8-speeds are doing just fine even in the winter driving, another local owner is getting a Maggy installed in 3 weeks on a '14 8-speed and we'll see how the 8-speeds like low-rpm torque. My brother is also the back parts guy at the dealership that had the tailshaft failure in Airdrie that audio1er had been talking about. So that's my proof, yours is one guy in Russia, on a forum?

 

[Two Dog]

I guess special things happen in Southern Alberta.

Not 1 person in here who runs one has said anything? Really, no one on the internets has one?

Could you give more details then about the installs and tuning since you had a hand in it and how they are driven, etc.

Thanks

ProCharger Supercharger Blog » NOW SHIPPING 2014-11 RAM HEMI 5.7L Truck Systems! says 45% power gain. Sorry but no 4th gen will Dyno at 335whp stock. All I'm saying is, with this kit or other FI you are skating on thin ice with your tranny, you are right on it's limits. It's your truck, do what you want. You can go full bolt ons and retain good drivability and make decent power.
