I have a GT-R with an LS3 based Katech motor. Has anyone gone with a Procharger or other centrifugal supercharger? I have had top mount screw and PD blowers on other cars and I like the power delivery (HP and TQ) curve on a centrifugal blower more. My second choice for power adder would be turbos but I like the look of the exhaust without turbos. Im not looking for insane power.....looking for probably 10 psi and e85 as a fun street car. All thoughts are welcome.
Any RCR 40 / GT-R gone Procharger?

I doubt you could fit it without extensive modifications ... not much front clearance room
plus why do it - top mount blowers are just so much better for drivable power delivery .... i have a 1,000 hp gen 2 viper w/ a procharger as well as a gen 4 and 5 n/a builds that are heads/cam/etc. .... although the gen4/5 dyno lower they're way more fun to drive because the power delivery is more consistent. the torque curve on the procharger is just stupid high up the power band, so you have to beat on the car to get to it, and then it spikes (which then causes other issues, like massive wheelhop if you arn't setup right)
and almost every single routine maintenance item, like a belt change, begins with "remove blower"
tldr - i prefer n/a builds ... big cubes/heads/cam ... since they're simple and reliable. Procharger dead last.

One disadvantage of centrifugal superchargers is that boost pressure is a function of the RPM squared. A Rootes blower is fairly linear.

I'm going to disagree with the other opinions. Mine is turbo'd but with big displacement and moderate size dual scroll, power delivery is not that different than a procharger.
1. The power delivery fits the SLC fairly well. You really don't need gobs of torque at low RPMs. With some downforce 800hp is very manageable at speed.
2. If you remove the factory water pump from an LS (use an electric pump) and plan your accessories, then you gain a LOT of space out front. I have my motor slid way forward, so much so the axle angle with the graz is questionable. And I still have room to change the alternator. I even have the AC pulley on (though no compressor right now).
I use this manifold and Davies Craig pumps:

Finally, a clean, easy way to do a remote mounted water pump or relocated radiator setup without the need for countless fittings and hoses. Featuring 4 female -16 ORB ports, we leave you with multiple plumbing possibilities, for that simple 2 hose setup. For cars that still retain heat you can...
