SuperChargers for 370Z
 

Does anyone know what is a good shreaking sounding supercharger for the 370z something thats not quiet like the stillen one for the 370z but loud and scary the stillen supercharger for the the 350Z......or is there anyway i could convert that over to the 370z.....help i dont like quiet weak superchargers

So what you're saying is quiet = weak? :shakes head:

BTW, there are only two SC system for VHR motors. Stillen or GTM. Neither uses root type SCs like Stillen DE SC systems.

Actually I take that statement back... I just remembered a SC system from Japan. This is on a G37 coupe aka Skyline 370GT (CPV36).

Annnnd I found another one. This one is on a G35 sedan with a HR motor (not VHR) aka Skyline 350GT (PV36).

what are the names of those supercharger?

and the same supercharger systems for the g37 fit the 370z exactly right?

Yeah, more info on the G37 roots blower kit, please!

I've no idea. All I know is that they exist in Japan. You'd have to ask someone who understands Japanese and look for these on Japanese V36 forums.

Japanese = expensive

i guess im going all out then thank you and dont for get to check out openclutch.com

This might be the top secret if I remember right.

Whats the power/power band different between a root style and the style gtm/stillen uses. If its almost the same i might go root style when more info comes out. I miss the high pitched whine of a supercharger.

If you miss the high-pitched whine get a wife. :icon14:

My former E-55 was a blast to drive. Too bad it broke down on the way home from Indy-GP last year. The repair bills had me sweating, so herein lies my purchase of the Z.

ProCharger
 

You want screaming sound?

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.

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: :owned:

:hello:

Good to see another Okie on here :)

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.

Therer's a few of us around. :driving:

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

Would love to if I'm up in the area... didn't you say you were installing a turbo on someones Z soon? That would be worth a looksee! :stirthepot:

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

Right now we're doing a GTM TT on an '08 Nismo :tup:

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?

It's all relative as far as size and an engines characteristics. Myself, with the good torquedelivery and gearing of the 3.7 in the Z, I beleive the the centrifugal is the better choice for tractibility and control. I have had a few FI rods in my day and it is important to match the FI systems up with the the motor based on the characteristics of the motor i.e. cams, power delivry, before hp and tq levels and where in the power band their the strongest/weakest.

By no meas is the 3.7 a big torquey motor, but it does offer good torque down low and the gearing puts it in the meat of that torque pretty quick. So, to maintain a level of traction and control the centrifugal is the way to go in my book.

You are right and I happen to like the way a centrifugal S/C makes power. But in most cases in a stop light to stop light situation positive displacement blowers win.

I guess it all comes down to what you are going for. Sometimes the lack of tractability is what is fun. I like having a car that can get squirly in 3rd or 4th on the highway, it doesn't make for good times around the track but it does make for good entertainment. :driving:

Actually the thing about the GTM S/C I like the most is the use of the Rotrex. It seems like it might be a good balance between the two.

:iagree:

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 :yum:

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 :tup:

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

For reference...

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.

agreed

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

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