With very conservative tuning for fuel variation, HP on the Auto's is usually around 550-560+rwhp, and Sticks are 570+rwhp on our Mustang Dyno. This is with no manipulation of the throttle body, or use of any restriction device. (Just normal strait forward tuning) Obviously like always a custom tune for local fuel type will lend to highest HP numbers possible.

As far as sound goes, you can order the P1-SC-1, and D1-SC with the Helical gear upgrade. When you do that ($100) it makes the head unit virtually silent. The C7's we have as BETA's are actually set up that way, however a few customers have requested they get standard head units, because they want to hear the blower "whine", so its nice that we have the option to make them however the customer wants.
Each gear set gets matched per the customers request. So when a customer tells a dealer "I want a loud blower" we can do that for them. Every supercharger gets tested before it leaves, and that includes a dB rating. So we can always look back using the serial number, and see what the sound rating of the blower was before it left. (Pretty cool actually) If the customer doesn't request a specific sound level, we have a tolerance which we consider "in-spec" for our QC procedures.
Head-unit sound will vary from application to application, due to bracket(s), which way the inlet is facing, idle RPM, and Cam design. ECT. So its hard to compare them due to those factors, AND you never know how someone wanted it to sound.
CLIFF NOTES: If you want it silent, we can do that. If you want it LOUD, we can do that as well.
But yes, the main difference is sound. And that one version can't be plumbed back into the intake if the customer wants, or have a filter attached to it, to make it even more quiet.
Why not make a blow off or bypass standard in the kit that vents to atmosphere with say a 3psi spring (or adjustment) in it? This would decrease IAT temps for sure, as you are venting pre intercooler, many of us have been doing this for years with great success. Would have been nice to see this incorporated from the get go. Yes Its louder, but its bennificial as well regardless of how efficient the intercooler already is.
The photos I posted in the original post is very detailed. Its the same files that feed the CNC machines. There is no difference in the brackets that are shipping out the door, and the images I posted.
Thank for the kind words. Its appreciated

Normally we don't post results with anything other then stock cars. But this is also the first time we have seen a car loose power with exhaust change. (No it was not a tuning issue, it took tuning to get the car back to just 10hp down, and 15ftlbs) And felt like it was worth sharing our results.
Maybe others won't have these same results, However at this time we just don't have enough data points to pass judgments. (We have are results, and are told by others they are having the same results with FI cars) Normally we are VERY supportive of customer doing headers and exhaust changes, cause who doesn't like more HP and a killer sound?
I do have to say this again, We are not in the market of making/installing/selling exhaust, so pardon me if we do not go into this matter further, just simply stated our experience.

These valves are specifically built by procharger for supercharger applications, no need to mess with springs like you may with a universal bov like a tial.
My proflow was fine out of the box and I still use it in combination with my tial to vent all 18psi

I believe (and I may be wrong) that it actuates at 3psi and maxes out at 10-12psi.
I would recommend upgrading to the better valve that they offer the first go-around.

If the BOV is the part of a Procharger that's too loud for some people... yikes.
Those straight cut gears will announce your presence from a block away (not that this is at all a bad thing)! And of course, they have the helical gear option (which I have never heard in-person on a Procharger-equipped car to date).

Debating between this and a ECS kit. Need to get some prices.

We installed an ECS kit on our shop C7 and did not have to "mangle" anything... Moving an ABS module less than 1" is not an issue and is being severely over "dramafied" on the internet.

If given the choice I'll choose the Procharger method of not twisting or distorting any component on my abs! It's a matter of opinions. Late Model Racecraft was on reddit saying the ecs method was a big no-no. You don't seem to mind.
For me, only the best will do, and that means a system that doesn't alter the abs at all. Excited for the quote! Get me some Procharger boost someone!

With all due respect to LMR they have not seen/installed/tested an ECS kit that I am aware of. If I felt this was an issue I would certainly have not put it on my car or offer it to customers. There really is no twisting or distorting of any kind, but I do understand your point of view

You are the blower manufacturer but you also product "kits" so wouldnt you want to set them up to be as efficient as possible? One would think so. By adding a BOV that vents to atmosphere post blower discharge it will vent compressed heated air to atmosphere pre intercooler.. This alone makes the system run cooler as the intercooler does not get "preheated". So I dont quite understand what being a manufacturer has to do with adding one of these at the production level when it should be a standard option for the kit as it is with many others. I know the location of your "bypass" is correct, ultimately my question is at what point of vacuum/boost is it open and closed, how is it set. Im not busting anyones ***** here, its a honest question.
If engine is above vacuum, its closed, to create boost.
If the engine is in vacuum, its open, to bypass pressure.
That is how all bypass valves work, no matter who makes them.
The about the only thing that varies is the amount of CFM they can move. (And whats funny is that flow data would make people laught, that the "tube" style actually outflows the venting style units. But thats a whole other topic)
The only difference in the valves I showed that we make, is that one can be recirculated to the inlet system, for those that do not want to hear it when it vents under high load/high cfm. (The flow data is actually very close between the two units) We send the kits out stock with the "tube" style, and a K&N style filter over the end of it. (To make sure no debris gets in the end of it.
Also the photos posted are not detailed, they are CAD renderings. I as well as others would love to see actual photos of the parts. Crank pulley, Crank Drive pulley, Blower bracketry, off of the engine. A CAD rendering is is not the same thing as a photo. Also, that is not the same file that feeds the CNC machine... 
Thats a Drawing, no different than if I were to draw it up myself in solid works. The program that goes to the CNC looks nothing like that image. That would be CAM file with toolpath commands.

What was being stated is that the CAD image you are looking at, is the file that the CNC file was created from. The only difference you would see is that its a satin alum. finished piece of metal. About the only details missing are the dimensions.
WHICH SINCE you asked, and we have nothing to hide.
At this point, I think we are the only centrifugal company to show both CAD drawings, and actual photos.
However, don't judge those images, I just snapped a couple quick ones, because it was asked. Also please note, that some magazines have discussed "exclusive" photos until they run their stories on the kit release, so I am limited in what I can show. (at least for now)
Seriously, post some photos of the components. We would like to see what that $5K is buying us. 
If we want propaganda or marketing fluff we can just step back into the pfadt threads certainly no need for that here with a real reputable company that has earned its stripes!
As I can sneak away from projects, I will get items up here like the "How-To" as fast as I can.
However I will not get into debates about why being a manufacture we do not put Meth Kits, or wastegates,restrictors, etc. on our systems. (That is up to dealers/installers/customer if they chose to do so)

So what would a black d1sc kit with a tune ready to bolt on cost?
