Procharger Stage II vs HO Intercooler

My Procharger order just came in the other day and I'm worried my order might be wrong after going through the parts. I ordered a stage II tuner kit with the D-1SC through Lethal Performance, which had the following title: "Procharger 1FS301-SCI-6.2 2010-2014 F150 / Raptor 6.2L Stage II Intercooled Tuner Kit w/ D-1SC"

I was going through the parts to verify there were all there, and started looking through the installation manual. There were two different sets of instructions for the HO and stage II kit. There are also two different intercoolers. According to these diagrams, I received an intercooler from the HO kit. I called Procharger and said the order was for a stage II kit, but appeared to have a HO intercooler. The representative confirmed the order from Lethal was for a HO kit "1FS301-SCI," and the stage II kit should be "1FS201-SCI." Anyone with a stage II kit here that can confirm this is the case? I'm sending an email to Lethal to see why their description and serial number don't seem to match.

Here's what I'm looking at...

Not many procharger guys left on here for help. Maybe @MurderedOutSVT or someone else can point you in the right direction.
Looks like you got the bigger intercooler, so thats a good thing!!

Do you have access to a good tuner that is familliar with the Pro-Charger on a Raptor?
Can I ask why you went procharger over Whipple or a TVS (Roush VMP etc.)

I'm MurdersOutSVT and I am a Procharged stage 2 DSC-1 user...

I bought mine with the Procharger already installed. It's set to the premium tune although I was going to get a custom dyno tune until my engine slung a rod. Not related to being supercharged as far as anyone can tell, I got the luck of the draw with a weak block.

Prochargers sound wicked and you know what it is without even being told. Gobs of topend torque and HP. I mean hinges off the gates of hell torque....over 3500 RPM'

That intercooler looks small compared to mine.

I'm curious about the Procharger vs the Whipple too. Whipple seems to make a fair amount more power.

I know a shop that did the whole Procharger thing upgrading everything possible the Procharger offers and went to the track quite often.
While it can make power like the Whipple, they went through 3 engines before giving up.
Now the owner is playing with the Gen 2, I haven't been there in a while, so he's probably on to a Gen 3 by now.

I called Procharger again and spoke with another tech, who confirmed my order had the HO gear. Apparently the HO kit has a 6-rib set up and a smaller intercooler. The stage II has an 8-rib belt and a larger intercooler. I've been dealing with Chris from Lethal Performance, and he has been awesome. I sent the kit back shortly after the original post and I'm waiting on my stage II kit now. I called Livernois last week to quote out the install, billet oil pump/gears, and a dyno tune, but I haven't heard back from them yet. I'm not too worried at this point, because I don't actually have an ETA on the new kit.

I considered a few variables when I came time to decide which system to go with. I bought this 2014 Screw with about 75,000 miles on the clock, and I'm sitting at 100,000 miles right now. I only had one issue with a radiator leak at about 85,000 miles, but I'm not ignorant to the fact that this truck (and engine) will not last forever. If this truck was new, I would have gone with a Whipple, hands down. But it's not, and I think the Procharger will introduce less stress on the aging components while still giving a significant boost to performance. The choice mostly came down to me not wanting to blow my **** up (famous last words of someone boosting a 100,000 mile engine.)

I know boosting this late in the game probably isn't the best idea in the world, and there are plenty of people who will say "just buy a gen 2, it will be faster anyways." The thing is, I don't care. I love the first gen raptors. I found a clean one and I'm having a blast with it. Now I'm going to boost it and laugh while making wooshy noises going down the road. :favorites37:

The points you are making for going to Pro-Charger are exactly why I was asking. Not to deter you from going that way, but i have seen way more isses with that setup than any other. The tune is critically imprortant on the procharger vs the Whipple or Roush. They seem to build boost in a way the PCM can not compute. @MTF has a good explanation for the issue.

I had 125,000 boosted miles on my 14 and never felt that the engine was being overworked. Although I do believe the Roush may be a little easier on the 6.2 VS a Pro-Charger just because a PC needs RPM to make power. You have to run it harder to get the same power.

In theory, the centrifugal should be easier on the engine than a PD supercharger. PD superchargers by nature create higher cylinder pressures at lower engine speeds, which is where the loading is harsher on your bottom-end. There are ways that centrifugals can improve lower engine speed performance (orifice plates and pulleying to increase the boost at lower and mid rpm and sizing the plate to restrict to a specific intake airflow. Ex) pulleying for 15 psi but restricting airflow to produce a max of 8 psi, which may be reached and carried from 4000rpm on, versus with a normal 8psi pulley combination and reaching 8psi at 6500 rpm, but only making 3 psi at 4000 rpm).

The issue seems to be tuning related on the centrifugals, with the limiting factors being the PCM Ford has on these trucks. Having tuned turbos, centrifugals and PD setups in the past, PD’s are really easy to tune.
