Supercharging A 350z

[Mr_GaZZa]

Hey guys,

i might be scoring dads unused Supercharger for the Z...

just wondered what mods i need to run 5-6psi boost on stock engine with a intercooler.

i aint to sure what the stock injectors/fuel pump can handle/ what the ecu can do as in being tuned...

thanks

Talk to Jash at C-Red. Pretty sure he has done a couple.

So has X-Speed

Mr Gazza, As part of the HKS kit, both the fuel pump and injectors are upgraded, as there isn't much additional headroom in them. You'll also need something to control the fuel/timing as the stock computer won't handle the changes well.

vq35 vipec's plug ins are in development , v88 wire in would work right now although you would be the test guinea pig to calibrate the drive by wire (or ditch it) . stock ecu remains to talk to the bcm to control all non engine car functions .

be wary of the supercharged stock internal vq , they make a bucketload of low down torque even at small boost and are prone to hurting rods . even a basic rebuild with some forged stuff might be a good idea if for longevity if nothing else.

will be an awesome engine though , so responsive .

Hey guys,

yeah i wont be aiming for high hp, just enuff to piss on 6-7litres common-dores.

I've raced this dude in a yellow VZ 6litre HSV 307kw with a bucket load of mods, i had him by a few feet both on the lights and rolling pulls!

think i'd be happy with 5psi

i been reading stuff like this... which makes me think you can just bolt it on pretty much?

Yeah i'll call C-red n that see what they can do / reccomend.

Still open to ideas ect.

Manufacturer: Stillen

Manufacturer's Web Site: Here

Type of Supercharger: Twin-screw

Additional Modifications Required: New hood that will clear the supercharger. These are offered by Stillen as well as other companies.

Price:

Stage 1 - $3,795.00

Stage 2 - $5,239.00

Stage 3 (Pulley Only) - $89.00

Stage 4 - $849.00.

Approximate Installation Time: 10-12 hours.

Future Plans: Stillen is reportedly developing a larger blower. They are being tight-lipped about it, but I was told it will work with the same hoods that work for stages 1-4 and most of the Stage 4 components. I would say it will have to be an M90. It will probably also have a larger intercooler. All of this will bump up the power quite a bit. The new upgrades are expected to be completed by the end of 2006.

There are 4 stages:

http://www.stillen.com/superchargers..._Guide_USA.pdf

Stage 1: This stage features the base supercharger with 6psi of boost. It includes everything needed for installation.

Stage 2:This stage features the base with 6psi, and it adds an intercooler as well as a heat exchanger with a coolant pump (with its own coolant) placed underneath the superchargerand.

Stage 3: This stage replaces the base pulley with a small pulley that increases boost to 7psi.

Stage 4: This stage features a new fuel pump, a larger 7th fuel injector, smaller pulley and remapped FMU (Fuel Management Unit) which increases boost to 8.5psi.

Mr Gazza, I personally wouldn't rely on what Stillen post on the internet, go talk to one of the tuning shops that have supercharged a Zed (C-red or Xspeed) and they'll have alot more useful info of what is required. I agree with Autoworx that the VQ35 isn't a strong internal engine, unlike the VQ30, so don't chsae too much power.

Cheers

With the HKS S/C on my V35 it was good enough for 312rwhp on only 6psi boost.

Internals were fine for street use.

Same power and less weight than a HSV you do the math :-)

S/C less likely to harm rods than a turbo setup

Thanks all so far for your input, more is still welcome!!

Hey Chris, so u have you Supercharged yours / or someones 350z?

I just really want to know if all the stock stuff will be okay 'ecu/fuel pump/injectors' and can the stock ecu be tuned? i cant seem to find anything.

But i am calling C-red tommorw, i had to get valentine stuff today so had no time!!

And guys as i have stated a few times, i dont want 1000000 RWHP or my rods ect getting thrown through and out the side of block LOL !!

Its pretty quick as it is and most things cant beat me.

I just want it for a bit more power / BOV and yeah cause i can

[two_evil]

i would go talk to marks workshop they have done a couple of z's before and they know there superchargers

[RICCA]

xspeed charged my mate close 2 30k!!

Don't make statements without explaining any of the facts.

Mr Gazza, Chris had the SuperCharger on his V35, was a very neat install, looked like stock

[xtc]

i was going to go the same way, to supercharge the v35 but got quote 14k (including labour cost etc) and this was through with vortech. one of the members JaiK before had one for sale and it seemed mint so i wanted to do what he did. he managed 360hp and 1/4 was under 13s. he did his at c.red.

but in the end...i spent the money buying another car

The graph doesn't show boost pressure, and at that power the standard internals won't last long

[two_evil]

The site doesn't have a spec list on the engine. However you can't deny that it has awesome power. If had i Z thats where i would get it charged

[GTS-t VSPEC]

The high point of the power graph is certainly high, but the average power (area under the graph) isn't.

[Mr_GaZZa]

doesnt look 2 bad!! i dont think i'd want that much watever a supercharger + intercooler will let it run @ safe boost /AFR

=] got a few calls to make

[ZXY]

let me know how it goes gaz as im still deciding wether to go the turbo or supercharger.

[Mr_GaZZa]

i'd rather turbos bro coz they force induct and hold boost on, but lots more work involved aswell as cash aswell... s/charger is bolt easy induction mod really... takes few % of power you gain coz the pulleys n that!

still deciding and getting ideas myself
