Anyone interested?

I have no price or power figures but my source suggests that by end of Feb 04 US emissions testing and all that will be finished.

Basically I'm down to 2 choices. The ATI or the HKS unit. So let me know if there are any takers.

 

Although the Procharger is a smick looking unit, the flack on the forums regarding the unit and the Company's seemingly putrid attitude puts me right off.
have you seen:

regarding the Vortech unit? (they have the ATI Procharger also)

I won't be considering f/i 'till the bloke that sells it to me installs and manages same.

ps - the vortech has 3-year limited warranty, but USA might as well be on the moon!

I had a look at the link and this seems like a nice unit. Cost around $6,700AUD and 4-5 hrs installation. In other words around $7,500AUD delivered and installed. Gains +83kw. Thats starting to look tempting.

I am not an expert but are Superchargers less stressful on the engine than Turbo's. With turbo's you can control the boost to make the turbo more agressive which is fine when you want tons of power, but too much too often will put additional stresses on other components like clutch, gearbox and other drivetrain components which will cause them to fail early (particularly the clutch).

Any of you folks had experience of Supercharger v Turbo's and particularly of their drivability?

If you want to buy a SC you can get CAPA to install it. They do a lot of work with Vortech but they are expensive.

Our car will require extensive tuning to get it right though. Fuel delivery and timing are a problem at the top end of the rev range.

Finding an installer who is smart enough to listen and not be a know it all (thus blowing your engine) might be harder than you think. Look at all those experience tuners being taken to court in the USA.

 

Guess what I found!

Now have i got your attention ? Because that is the best price i've seen for the Vortech kit... I bet you the install and tune will be big bucks from CAPA.

 

I spoke with Tony from CAPA end of last year and this year regarding the kit. "to be the first kid on the block". I personally think the ATI is a better kit than the vortech.

Anyway just remember that the price quoted is "US Prices are ex. factory and do not include Shipping, GST and Import Duties" as stated on their web site.

PS: When I say the ATI is better than the Vortech I make the assumption that you will be using a new or piggy back ECU.

 

Superchargers and Turbos perform the same task they just do it differently. Turbo runs of the exhaust gaes to spin a turbine which compresses the air outside the combustion chamber, while a supercharger runs off the crank using a belt to spin the compressor, which compresses the air outside the combustion chamber.

Draw back with the turbo set up is that you need to get X amount of exhaust flowing through your turbo before you'll get any boost happening (Turbo lag), while the supercharger works from the word go.

You can control the boost on both Turbos and Superchargers(Using a smaller pulley to increase boost). The amount of stress etc will all depend on the boost you run.

Not sure if that answered you question or not?

I've had an aftermarket custom turbo and aftermarket custom SC on the same car (at different times of course) which I believe gives me a rare insight into both approaches. Both have their advantages but I far preferred the turbo.

SC had a heap of torque with a nice flat curve throughout the rev range. Cons with it was that boost couldn't be readily adjusted, maintenance on the SC unit itself was required weekly (just make sure the oil is topped up) and there was belt whine despite not being a toothed belt.

The turbo has a slightly less torque below 3000rpm but over took the SC from there to redline. No maintenace, boost could be adjusted and it was quieter when not on boost (and you're not on boost much at all on the street).

The fact the turbo would break traction in the dry in the first 3 gears without touching the clutch was fun as well. If I go FI it will be turbo without a doubt or hesitation.

 

Do you believe in putting a turbo or supercharger on a car that is not designed for one?


Murray

 

If done properly I see no problem with it. I had an aftermarket turbo on my MX-5 for about 7 years without a single problem (except a destroyed gearbox after about 5 years).

 

Did you change your compression?

What boost were you running?

Murray

 

Stock internals, 12psi

 

Jesus!

Im surprised it survived as long as it did, it would have put out quite a bit of power then!? What are the numbers on it?

How did it compare to your 350z?

Murray

 

New owner did a dyno run just after he took possession. It came in at 156rwkw IIRC. The 350Z is oh so slow in comparison. Same power at the wheels as the Zed but with an additional 500kg to carry around.

 

Thats pretty cool.

But im sure you'd rather own your 350z

Just do a few more mods.

Murray

 

The Zed is a more comfortable car. I'm still undecided on my long term plans though.

 

Your not considering selling your ZED are you?

Your just not sure about what your going to do to it?

Murray

 

No, not yet. I'm content to just wait ATM. Anyway, right now my Landy has my attention. Trying to decide on selling it, swapping in a new engine or rebuilding the current one.

 

Sound like a few $$$ to go into the cruiser. Pity you can throw that money towards the Z instead.

 

Aps..just put in the twin turbo kit... everyone that does it says it's amazing.

It just requires you to do more work with fuel and timing as with the SC and you get amazing power at 6psi. Max is running 9psi on the SC without a problem nowdays... Thats tells me the car can handle it as long as it has fuel to boot.
