I once called procharger and asked them if they offered helical gears for anything other than the p1sc/d1sc and they said flat out "no". The f-series have more aggressive impellers and are rated to a higher rpm than the p1/d1. That's where the extra output comes from. I'm not sure what makes an f1 able to spin faster but I'm guessing it's a lighter gearset, less rotating mass. There are aftermarket impellers for p1/d1 but the good looking ones are cast aluminum and are heavy. Already had one break apart on me and it was a disaster. It's hard to cnc the curved veins from billet but I'll figure it out soon enough.

From what I gather. The reason the F1 can spin faster is that the compressor housing and impeller fabrication is different. I spoke with one of the techs and he told me the reason the 62000rpm limit is there is a safe margin for heat production. The impeller gets too hot causing expansion and can rub on the housing, destroying the blower. The F1 impeller for one is much more aggressive, made thicker and from a different material. Although he said for street application he himself would never get anything other than a D1. The F1 is significantly harder on an engine because of how the boost comes on. The D1 is a very smooth delivery.
Also he said to minimize heat and increase hp to remove the inlet. Add a velocity stack with stainless mesh and a oil soaked nylon sock over the stack for maximum flow. Also reduces heat. Just needs alot more maintenance than a filter. He also said the filter that comes with the kit os very restrictive and is only really good for stock engines running 7psi and under. upgrading the inlet on a modded engine can yield up to 100 extra hp. This i have confirmed for myself. I run a truck air filter that very barely fits under the hood. My hp went up significantly and my inlet air temp went down also. The limits of the D1 are also tied into how the engine is setup. Having meth injection changes how it can be tuned. You can get over 800whp easy on a D1 but looking at engine setup is where you should go and not just blower ypgrade
I know this is old, but I figured a little updated resurrection of this thread was in order...
My car makes 911/792 at the wheels with a D1SC, on only 12.5 degrees of timing with e85. (decided no reason for more timing since I went back to being a street car and quit chasing times and it did so well as is)
My friend and tuner also has an auto C6 Vette making 906hp at the wheels with a D1sc as well.
900+ rwhp is definitely achievable with a correct setup. I made 882/781 with the previous motor, and my new motor is even better.

Great numbers. What intercooler setup and how much boost for 911/792 ? Was this strictly on E85 or was Meth also used? Any other details besides what's posted on your profile is very greatly appreciated. I would love to one day perhaps up my setup.
Agreed. You can make 900 with a D1SC. It is A LOT easier to do on a D1x.
For those interested, I put this up a while ago. You can see the difference between how a D1SC and D1x build boost - and why it is a lot easier to hit a higher HP number on the D1x. But, you do lose a moderate amount of low end with the switch.
These are two boost curves corrected to 70 deg F ambient. This is on a car where everything else was the same and just the blower was swapped. Same pulley, same everything - both spun to 62,000 rpm.

I have a dual air to air intercooler setup with 2 smaller coolers, 1 each in the nose holes on each side of the grill. The car is on E85 only. Made those numbers on 19.5 psi.

Are these the Twin 4.5" Procharger Intercoolers? Also do you recall what pullies were used to acheive 19.5 psi?
Thank You

My setup is custom. I used a vette style procharger setup on my camaro, instead of the fbody setup. i have the blower belt separate from the main drive and all my accessories are vette spacing instead of fbody, and its ran with a stock LSA balancer and a 3.70 pulley on the blower. The intercoolers are the 3.5 inch procharger coolers, but we cut the 2.5" inlets and outles off and replaced them with 3". The piping y's into them separately, then y's back together before going to the engine. These little intercoolers are great when you put them where they can get better air.
