For those that have been down this road, and I know there are many, which ProCharger did you choose and why? I've limited my selection to the D-1X, the F-1A and the F-1A-94.
This will be a street car and will see limited track duty. Primarily a fun car to drive but a monster from a roll. My concern is gibing up the low end torque for the top end power. That's the dilemma we all go through, right? I've struggled to find dyno charts of said variants on the C7. Z06. Best I can tell as long as you keep it above 3750 rpm, the bigger the blower the better. But how is that for just tooling around town when you don't have your foot 100% in the gas? It still needs to be fun to drive and an enjoyable experience when not in kill mode.
Is giving up the area under the torque curve worth the top end is the question. Detoxx03 seems to be quite happy with his D-1X on a C6, and others seem happy with the F-1A-94. But for street use, opinions from those that have been down this road with real world experience would be appreciated. All the supporting mods will be there to make the most out of the situation.
I am looking at the same decission soon, upgrade to the 2300 or 2650(if actually comes to market) after the first of the year, or go the centrifugal route. Not a track car exclusively but more of a street car and roll run. Looking for info or at least a location to help with the choices.
Your not swapping the blower for just 700rwhp. Do it once and put an F1a-94 on there. That way you are good from 800-1050rwhp range without changing anything on the blower kit except a pulley and belt. Run a large BOV from the start. If you dont plan on over 750-800 then keep a PD blower.

I spent MONTHS going through exactly what you are asking. In the end I upgraded to F1A-94 by Procharger's recommendations. It's based on the F1A just a larger impeller etc and a newer design. Good for 1200 horsepower plus. I wanted a street car that could do drag + road course. Listen to the above quote do it ONCE and RIGHT. I have the BIG RED Bypass valve PLUS I am using the CRFUELER port injection system with the 46mm Precision wastegate addon which allows me to control boost pressure like a turbo. I can turn the boost down for 93 octane vs pulling timing then on E85 open her up. Just a better way in my opinion to control power for a belt driven supercharger. Yes it's complex you will need a secondary fuel system + port injection system + DOME pressure solenoids and a good tuner I would recommend Chris Crawford if going down that path.
To me if you want to stay under 800 wheel stay away from a centri blower just do heads/cam/ported blower with 103 throttle body on flex fuel and call it a day. If you are wanting track duty aka road course you will need a flex fuel setup I would not recommend an Alky kit or Snow kit for that. So now you want a low side + port injection system = $$. Just depends on what you want in the end.
F1a-94 all the way. I had a stick m7 making 800whp with a f1a-94 and it hit hard and pulls hard all the way up top. I now have an A8 making over 1050whp with a f1a-94 and just went 8s with it. Video will be posted soon.

What these boys said...
I went F1R and i regret not getting the F1A94. Seems to be a perfect match on these cars pound for pound boost wise. But im still very happy, just kinda stinks knowing you're leaving some power on the table.
I'm currently making 860 on pump and meth, low 900s on 40% E85.
Decided on the F-1A94 based on a ton of research and the input from this thread. I appreciate all the input and sharing of personal experiences! Happy to be joining the F-1 ranks.

<900 D1X, >900 f1-94. Bigger blowers are harder to turn, and rougher on belts. No reason to go big blower unless you are going to make 900+ later, then do it once, but if all you want is 800-900 do the d1x and enjoy.
I just got my F1A-94 + Crawford Racing Port Injection w/ G1Pro intake 1000cc inj. + MagnaFuel 750 custom low side (all supporting mods like long tubes, etc) and I can tell you it's an entirely different car in a beast mode way. The only real advantage I see of the stock supercharger or smaller blowers is below 3k rpm but keep in mind the car is a V8 with still plenty of torque for driveability. I am telling you when I stomp on it I don't regret that F1A-94 one little bit it feels like someone strapped my car to a damn fighter jet. I had K&N Carbon Fiber intake + Kooks long tubes + 3" x-pipe + Borla ATAK + custom tuning before I did the huge build and that can say it doesn't even remotely compare to how fast it feels now. I am smiling from ear to ear and I am still on 93 octane. When I get more access to E85 (buying it in bulk) the station is 40 mins from me the car will make quite a bit more power which is just hard to swallow b/c it feels insane right now. Another thing I noticed b/c the power comes in smoother it hooks better, well as good as CUP2's can hook when hot. If I was just going for under 800 hp I would just stick with stock blower and do heads/cam on a Z or do a 2300 and heads/cam on stringray/GS. Just my .02.
I went with the D1-x as based on the forum here they've mentioned with the F1a-94 I will be loosing the low end and the RPM should be high.
Once the car is ready we will see how much It will make
yes there is definitely a trade off between the D1-X and the F1-A94. Do you want the massive torque from a smaller blower or the top end hp from the bigger one. It all depends on what the user is looking for and what he/she plans to do with it. Stock tires already struggle to hold the torque in second gear, so in my situation I'd rather have the pull up top than more torque to rip the tires loose through 3rd and 4th. I don't plan on taking the car to the strip much at all, but roll racing/half miles are more my style.
Mine initially lost some torque when I first put it on but some tuning tweaks and it made it all and then some. Still doing a couple minor tweaks but as of now it makes 980/796 vs the 933/758. The D1X is a badass blower and would put it up against any for the power and powerband it packs.

what kind of fuel system are u using to get into 900s
