Small motors that make power at higher rpm levels will benefit more from a roots type blower due to lack of torque and power in the lower rpm range. larger motors with good torque characteristics benefit from using centrifiguls since they already have the torque and power down low and need help breathing on the top end.

Both supercharges will work and peform well but after owning both and in different applications I preffer the centrifugal with a motor like the 3.7 in the Z. And the reason why is becaue of traction, I don't have any desire to set my Z up like a drag car just to get better traction when I can make as much usable horsepower with a centrifugal as a roots and have more tractible power in the range I would use it.

We aren't driving 4 baggers here. Our engines are perfect for "roots" (using the term generically, I prefer twin screw). "roots" got a bad name the 350z world because Stillen used too small a model on the 350z (for clearance reasons probably, but still..). I guess ZR1 owners should be told their cars aren't trackable.

On topic, but a different direction.

Do you think they will come out with pro-chargers anytime soon. They seem'd to be very popular on the 350 back in the day.

Maybe for the first 18 months in the 350z world, but then because of tuning problems mostly and some high profile blown engines, they fell way out of favor.

I didn't know that. Thanks for the insight MMC. I guess no pro chargers then...lol

We lived in St Louis when we had our Vortech powered 350z.. You ever see us run it at Gateway?

Drag or Road course.

I have never dragged before. Me like the twisties

Drag. It was my wife's car and she would run it.. High 12's mostly. I had something with a little more HP ;)

LOL..nice! Family that races together stays together.

I believe "procharger" is just a brand name for centrifugal blowers...

What would be awesome is a roots blower kit :yum:

I'm sure a ZR1 would do just fine on a track whether during a track day or competing. Don't get me wrong I like roots (in particular) twin screws, it's just my opinion that for MY Z I would rather have the centrifugal for the street. I'm not a racer and never will be. I like my cars to perform on the street. And once again not that a roots would no peforma well on the street it's just that I prefer the centrifagul's characteristics over the roots for street application.

guys lets clear this up a bit they are called positive displacement superchargers. there are roots, twinscrew, and G-rotor or scroll types. centrifugals are all variable displacement. in know roots is easier to say but you confuse the newbs and are hard to understand when you mix them up. on that note positive displacement superchargers disagree with the vvel and open throttlebodies and it currently* cannot be done on our cars. variable superchargers only work because of their sh*ty performance characteristics at low rpms.
