Thanks Everyone!

Good choice buddy, congrats. Gonna love the rush man!

Thanks SGDM! I probably would have done your setup but to get the car down there and back just wasn't worth it.

This is a great thread. I hope it helps others make a decision as well. I just wish more people with centris would have chimed in.

Can't wait to hear your thoughts once installed. You're gonna love it. Get some good rubber

Just got new wheels and tires are next. I plan on getting Michelin Pilot Super Sports. based on a couple other posts I'm wondering if I should be prepared to upgrade my suspension.

Once I get it done I will surely let everyone in this thread know.

I'll definitely chime in when I get my car back this week (ECS/Vortech kit).

Awesome! Thanks man.

I always find the comment that twin screws are more efficient kind of a misnomer. They are more efficient at maintaining increased boost pressure at higher operating rpms because they provide compression within the rotors. They gain a little boost pressure over the engine rpm range because of this inherent compression. The faster you spin them the more boost they provide (similar to centrifugal). But they draw more power to spin when the bypass is open (most of the time your engine is running) because they are constantly compressing the air. So technically if you are just cruising down the highway at 70 mph and not in boost your Whipple or Kenne Bell is going to take a lot more power to drive than your Maggie, LT4 or Eforce that is really freewheeling. Your car will lose a little fuel efficiency even if you drive it like grandma because the twin screw is always compressing air, even if it is releasing it through a bypass, it compressed it then released it.

The TVS PD superchargers are similar to gear driven fans in a sealed environment that are spinning roughly 3x faster than your crankshaft. Every molecule the supercharger grabs on the low pressure side is transferred to the high side and it is moving whatever it's rated volume is (1.7, 1.9, 2.3...etc) to the high side at the pulley ratio. No matter what your engine rpm the boost will remain relatively constant but as rpms increase the resistance and heat increase so some of the "boost" at higher rpms is due to temp increase more than air flow increase. The old combined gas law that if you double the air temp you also double the pressure without adding a single additional air molecule. Since we are trying to get more air molecules into the engine the increased temps are the enemy of the PD supercharger. This is why PD blowers have a reputation of having the power fall off at peak rpm. If you have a good enough supercharger cooling system you can still make a ton of power at the redline but the design just is not as efficient when you get there. Depending on model your PD supercharger is spinning between 15,000 and 28,000 rpm.

Centrifugal superchargers are kind of like fans blowing in a non sealed environment. They have to really get spinning (40,000+ rpm) before they really maintain significant boost pressure. They don't have a positive displacement guaranteeing every molecule is pushed to the high pressure side like the PD supercharger, they just spin and eventually the sheer velocity develops pressure. Because of this nature the boost climbs all across the rpm band. The faster they spin the more boost they develop.

Turbos are spinning in an open environment like the centrifugal but the rpms are much higher (100,000+ rpm) so they reach "ideal" boost pressures much sooner and need a wastegate to relieve the "excess" boost pressure.




Yeah that is huge advantage of the pd superchargers, they only take engine power to spin when the bypass closes and the car needs boost. Makes them better for real life fuel economy and EPA testing.

You seem to be very knowledgeable. In your opinion what do you think the average 0-60 speed would be on a stock 2016 2SS with a Procharger supercharger? Thanks...

Don't rule out bridge stone re 71r since your leaning towards a street aoto cross tire

Congrats on your decision! And yes, get good tires. These factory run flats with a 2300 blower are useless at moderate + throttle in under 50 degree temps until 4th gear, and sometimes 3rd gear is ok depending on the pavement.

Depends on transmission, ambient temp, and surface prep for the test. 3.6 is a good guess though.

Thanks jessrayo. I have an 8-speed auto. 0-60 in 3.6 sounds good.

What 0-60 are you getting now?

[sub_ETCS_ret]

I am trying to understand the differences between the Procharger p1sc, d1sc, and f1a. Other than rpm and max supported horsepower can anyone provide other advantages like lower end or mid range torque.
