SuperChargers for 370Z

OKC370Z · 06-23-2010, 04:21 PM

You'll have enough traction issues with a centrifigul, install a roots and you will have instant boost and instant loss of traction. My experience in the past has me leaning towards the centrifugal mated with an engine that already makes good low end torque for it's linear power and a roots for an engine that does not have much low end torque and requires high revs to get moving.

Without traction on the street or strip you get:

Good to see another Okie on here

If you make it up to Tulsa stop by the shop!

Sorry, missed this earlier. I have emailed you and got a quote for install of a few things, amoung them the Stillen SC. I am in the process or sorting out the financial so I can come visit you in the future. I amy just stop by some day an check out the shop and talk with you.

Typical of the tuning industry I presue you are open on Saturdays?

How many Cobra, Lightnings, or ZR1's do you see swapping to centrifugal? If you have a traction problem you solve it with suspension, tires, and weight transfer, not by swapping blowers.

Who said anything about swapping blowers? The intent of my statement above is for STREET applications. My opinion is that you're better off with a centrifugal rather than a roots type blower because of power delivery, based on what type of motor you have in the first place.

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.

I don't know about you but 3.7 liters is small in my book.

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.

While a centrifugal blower will work well on this motor, you just can't beat a properly sized roots SC for a nice flat torque curve and nigh-instant boost

A roots blower's one weakeness is top end potential (here the centrifugal will win the day) -- of course, for that you just match it to a big turbo for twin-charged madness

Without a doubt, if a roots blower kit is developed, it will eventually find its way onto my car

For reference...

Not sure what a procharger sounds like a WOT, but i would love my 370z to sound like this....with a REAL supercharger, not some stupid exhaust clip on.

If you are all about the sound than you might want to go turbo.

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

What would be awesome is a roots blower kit
