best Turbo n Supercharger out?

[Djgorow]

i've been searchin awhile to find the best turbo or supercharger to my 04 Z, i can't seem to make up my mind about which one to get a turbo or supercharger, and which ones are the best at a reasonable price...can anyone give me some numbers...

just go here and you'll find some stuff to help ya out some

Check out this kit for the Z!!!!! It is the hottest kit i have found for the 350z.......

I cant wait till september when it is supposed to be released. I am in the process of buying a track model 350z and want that kit to be one of the first mods!!!!!!!

Procharger is the way to go IMO.
It's an intercooled centrifugal supercharger setup.
Unfortunately, with the Z's high compression you can't boost very high on pump gas. If you were willing to add 104+ octane additive every time you fill that 20 gal tank you could do better...

350Z SuperCharger

I'd also go with anything JWT had to offer as far as intake and exhaust systems go. I believe they make a pop charger system for the intake.

The GReddy Twin Turbo 350Z kit.

Preliminary Specs:

Standard Boost - 5.6
Compressor - TD05H 18G (2)
Horsepower - 334.2 whp
Torque - 339.2

Includes Intercooler

this costs about 6 'gs though.

The Greddy TT kit period. NerveAgent is rite...it does go 4 like 6 g's.

[LancasterWannaBe]

Procharger advertises a 55% - 60% hp increase with their kit.
That would be ~440 - 460 FHP. (~ 380 WHP with 15% DT loss)

Although from what I've read about the AF Z car, the Vortech kit sounds pretty damn good also.

And to think, all you need is money

Does someone make a piston set specifically for lowering the Z's CR?
What is it with all the old turbo cars comming back NA??
Even the next supra is supposed to be NA.

But I guess if it works...

look at the dyno's. The centrifugal does not make quick boost while greddy TT kit will. The TT will make 20 hp more through the power range untill 5500 rpms when the supercharger passes it up. tubo is the way to go. You can tune it for race and then putin around town with a boost controller. turbo is the way to go.

[LancasterWannaBe]

... yea but with turbos, there's no boost bellow like 3000 revs or so...
And that's assuming they're ball bearing turbos.

Also a centrifugal supercharger would only take about 8 hrs to install or remove incase you blow your engine and don't want to tell nissan that you had a blower on it. Good luck removing a heavily used turbo exhaust manifold, the turbo, all the oil lines, air ducting, and electronics in 8 hrs.

With the turbo kits, you have to use a turbo timer to shut off your car(or you really should unless you're quite patient). Do these kits include an electronic boost controler or do you have to go out and spend the additional $600?

Where are these dynomometer charts you're talking about? Please post a link because I'm interested.

I just think a centrifugal supercharger kit is the best way to go, mostly because it could be removed quickly incase of a blown engine

[ArthurKing]

I think it depends on what you want...
I dont claim to know all there is to know about FI, but isnt a supercharger a smoother ride? and Turbos have that turbo lag before blasting off?
Anyways, i hear so much about the Greddy TT, its really the best way to go.
I do wanna see how the air power system turns out though...

[LancasterWannaBe]

A supercharger will produce the same boost acrpss the entire RPM range, so in that regard yes, it is smoother.

Yeah Turbo's have some lag to them, but it doesn't really matter when you're racing since you'll be reving high the whole time. I must say it is cool to hit that magic spot when the turbo(s) really start producig power - it's like a kick in the seat.

I would go with a supercharger because as mentioned above, it would be easier to remove, but I also would want a new car very streetable and "smooth" if I paid $32K for it.

All this goes to say that I agree with you in that it really just matters what you want.

the first is with the TT kit and second w/ vortech S/C w/ instercooler. Look at power to the ground at 5000 rpms.

Centrifugal S/C do not make instant power. Roots or twin screw styles do (jackson racing/stillen/kenne bell). A TT system w/ properly sized turbos will make power quicker then a centrifugal SC. A boost controller costs 300. Also one other thing to consider other the horsepower #'s is how much boost does it take to get those numbers. The Greddy TT I believe is putting out far less Psi than any other forced induction kit, which gives it room for improvement. However the SC are much cheaper. It just depends on how far you want to go.

[j_greene]

procharger
280x1.60(60%)=448
448x.82(18%loss to wheels) = 367@7psi

greddy = 347@5.5psi
*makes more power sooner and if you were to bring the boost to 7 psi it would make more then 367 at the wheels.

[LancasterWannaBe]

But what kind of heat is generated at 5.5 psi? Greddy probably set the system at 5.5 lbs for a reason.

One could also install a smaller pulley with better cooling abilities / higher octane fuels.

The question is, CAN you raise intake pressure without damage?

[j_greene]

They do it to keep it street legal. Turbos are harder to pass emmssions. The turbos in the kit can easily handle 15- 20lbs of boost. I have no idea how huch the motor can handle with the stock compression. The superchargers are nice and cheap but how many 700 hp S/C 350's are out there. That is an extreme example but at that level they use turbos and there is a reason for it. They are more effiecient. I am sure the cooling system can handle the TT kit unless you are running @ Daytona at redline for a couple of hours.
