Thanks, but I'd rather hear it from the horses mouth.. I.e. Pfadt, the manufacturer. Not speculation from a guy who likes their headers.
It's not rocket science, but rather simple physics. (I can't find the smiley with the tongue hanging out that I want here...)
For the graph they have and the dynos they've run, the best guess is the same 7-8psi everybody else is using.
The head unit is an Si Vortech, so those psi values would match the numbers accordingly.
tldr; 7-8psi.

Excellent questions!
All of our products are designed to be non-intrusive as a primary design criteria. Not only can the software be returned to 100% stock at any time, but also the hardware is designed to be returned 100% to stock. With the Pfadt supercharger kit, there is no relocation of the ABS pump, and there is no drilling or cutting of the frame rails, etc. Returning the software to stock is not a disservice either; Our kit is shipped with a cutting edge calibration that is second to none. This gives our customers a massive advantage. The Pfadt tune is fully adaptive to all driving conditions/environments and does not require "tweaking" or "tinkering". If for some reason though, someone desires to create their own tuning solutions that isn't based on Pfadts extensive validation procedure, they are welcome to do so by returning to stock. They of course not be able to retain the upgraded instrumentation that the Pfadt kit/tune utilizes, but that would only place them at the starting point of other hardware solutions (supercharger kits) and that is certainly not at a disadvantage. If anything, it speaks volumes to the proprietary features of a Pfadt system.
Our flash loader solution allows error codes to be disabled and we already provide two fan profiles for enhanced cooling. We have tested our supercharger intercooler design in stressed or severe duty scenarios ; we already account for any/all of these scenarios.We do not believe in "not doing one's job" as that is a dereliction of duty as an engineering firm.
Absolutely fantastic input! You've actually keyed in on some very unique points about what truly separates Pfadt from the others!
When you purchase a Pfadt product, the premium you pay is for the use of materials that have been selected without compromise, a system that is fully tested and validated that will work right out of the box. Extensive R&D, cutting edge designs, and exclusive features have resulted in the best kit available. This is not a piecemeal kit for "tinkering", and this is not a "budget kit". This is a OEM quality solution for those who desire to have the best system with all of the guesswork removed. With the Pfadt supercharger kit, we believe that what our customers want is something that has been tested and validated for all driving conditions including track duty, different altitudes and varying quality of fuel. Custom OS retains all OEM reliability and functionality, but with improved features. You should absolutely never be a guinea pig, and you should always go with a product that has been created with reliability as a primary metric.
Our supercharger kit will work as per the same standards of the OE components and you'll never have to worry about your tune being off because you're on a drive across the country and you're now at a different altitude or if the vehicle will tolerate regular grade gas or if performance will degrade at another location. The car will drive as reliably and will as reliably as stock, just with 50% more power (+200hp).
The bottom line is: What you buy from Pfadt will simply work, right out of the box. We try not to focus on how we are leading the way in HP/TQ, but rather on how we are leading the way with cutting edge innovations to create an OEM quality engineered solution. Regardless of location, expect the absolute best experience possible (Including international customers).

You are right, no need to hijack this thread, let's stick to the topic. PMed you back. Apologies for my reply which may have sounded rude
That was really uncalled for, and I'm sure some of the other vendors in the thread will agree. I was trying to be nice to you, actually. My mistake.
Keep it up, and nobody's going to want to help you. If you have a problem with me, PM me. Don't clutter a thread with your own trash. Also, PM sent.

If you have had posts deleted from this thread, read the following:
Online conflict
For the most part, the CF community remains a friendly place where ideas, thoughts, and assistance can be found. Unfortunately, there are times when members forget that this is an Internet forum and issues between members can get out of hand. This includes members turning to the forum to air a personal offline/on-line problem which results in sides being drawn by participating members.
In these situations, it is the forum's role to expeditiously end any conflict for the good of the forum and its membership. The forum's goal is not only to remain family, work, and corporate server safe, it also will not serve as a battleground where offline/on-line personal matters and drama are permitted to be played out in front of other members.
Any thread(s) that contain open bickering, name calling, subtle derogatory messages, "digs," personal attacks, or anything negative in nature will be closed/edited or deleted, and any participating members who post in violation of this rule, will jeopardize their posting privileges.
If any member is being harassed on-line in a thread or privately via PM, they should avoid a confrontation with the offending member and immediately report the problem to a section Moderator via PM, or by clicking on the "report post," icon
under their user name.
The Moderator will evaluate the issue and take appropriate action to rectify the situation.

Personal attacks/hostility towards others
The Forum should be a place where we treat one another with civility so that it remains a fun and friendly place to hang around with other Corvette enthusiasts. Hostility to others is rude and inappropriate.
Personal attacks cannot be tolerated. Attack ideas, not fellow Forum members.

I'm waiting to see what the eforce offers as far as pricing because they offer you a "powertrain warranty"
Also want to see what the Z06 MSRP comes out to because once you start modding, you just can't stop.

Edelbrock hadn't set a price by the time SEMA rolled around, but they did say that the cost would be between the current C6 kits ($5900 and $6900).
However, WeaponX (a sponsor here) has it listed at $8900 list: https://weaponx-c7.myshopify.com/col...vette-stingray
As for warranty, read it carefully - you may need to purchase additional coverage to cover the whole powertrain cost on the C7:

Some words for the OP:
I ran a Procharger on my C5.
The supercharger manufacturers themselves market their own kits. The C5 Procharger kit, and especially the bracket for the head unit, was PURE TRASH and a big reason the 2 established Blower kit makers/vendors on this board started making kits in the 1st place. Not suprising IMO, ProCharger and the other head unit manufacturers are in the business of making actual Superchargers. That is their specialty and area of true expertise. Trying to make complete kits too, and for every car/manufacturer under the sun, is not going to yield first class results. If you focus on such a wide range of vehicles you become a master of none.
I "upgraded" to a bracket produced by one of the big blower vendors on this board. It was light years ahead of Procharger's bracket, BUT I still got belt squeel, and also a tossed belts twice, and the accompanying involuntary removal of the hood liner.
This vendor went through MULTIPLE redesigns AFTER it began selling to the public. My bracket wasn't their 1st designs and far from their last.
I eventually upgraded to an ECS bracket. My cheap *** should have just bought an ECS kit from the get-go. Clearly superior in design, and MUCH beefier than the previous 2 brackets I had on hand. Never again a single problem with the car or belts.
Based on my prior experiences and actually seeing and holding parts in my hand, the next time I buy & supercharge an LS, or now LT, equipped Corvette, I will go with ECS hands down.
However, many people HAVE had great results with other vendors too, so I will simply state the following advice:
1. Consider a seller/vendor's area of expertise and experience level with Supercharging Corvettes.
2. Consider their track results. Literally. The results customers see AT THE TRACK.
3. Consider how many revisions key components of their past gen kits underwent. How radical were any changes made to the entire kit (Procharger's own kit was basically COMPLETELY redesigned. EVERYTHING was different except the head unit when they released their 2nd C5 kit)
4. Consider their own experience level with USING their product. Do they themselves track supercharged cars? How often? Are they on the front lines learning first-hand how the vehicles and supercharger kits perform?
5. Consider what you are paying for. Pure price comparisons are a bad idea. Why does one kit cost hundreds more or less than another? What is included? What is left out? Compare price AND components.
I personally would never buy from a head unit manufacturer, or from a kit maker that does not specialize first and foremost in these cars, or from a kit maker who has no prior experience before now. I would buy from someone with an extensive track record whose area of focus and expertise is supercharging Corvettes.
Good luck. You're going to have a blast. Just make sure to do your homework so you get there with minimal headache and stay there with minimal down-time or adjustments.

Thanks Bobby, much appreciated. There is some absolute ridiculousness going on in this section.
Absolutely over the top, jumped the shark, destroyed their reputation, ridiculousness.
Luckily the C7 market is an intelligent group and clearly have seen right threw it.

Doug your kit is absoute trash, what do you know about supercharging corvettes anyways??? Obviously those first time manufacturers have a clearly superior product! With there many many months of supercharging experience! 
Now where's my bracket....
