i was told by a reputable source in the industry that HKS was goign to release a more agressive pulley for their supercharger. has anyone else heard this, i love the idea of a super chargers reliability over a turbo, but cant get passed the semi weak gains from it and the huge cost? are bigger pulleys on the way?

 

I believe that, in time, both of the single turbo kits (APS and Turbonetics) will prove to be equal in reliability and cost to the superchargers while providing more area under the curve.

 

ya, but will the cops impound your car when they open the hood? this is what we californians have to worry about.
i, too, have heard about a pulley upgrade. call hks and find out for us?

 

I just heard that the Vortech kit is approved for CARB cert. All testing has been done on a 05 and they have the stickers coming!

 

HKS needs to worry about there compressiors braking first. I know of 2 now that locked up.

 

The Hks S/c Sucks ***!!!!!!!!!!!!!1

 

what the heck, i thought the vortech was never to be used on the road or some crud like that...what can we use over here in cali aside from the stillen kit????

 

I guess you've never actually been pulled over with mods. They don't give a **** if you have a thousand Carb EO stickers when they pull you over. They can still ticket/tow you. It is only worth it to have a EO sticker when you actually go to court

 

you're right, i haven't, yet. i need my car to earn my living, so i'm kinda paranoid about the whole smog/carb situ. i'd rather error on the side of caution, but that's just me.

 

Maybe you are missing my point. In SD it doesn't matter whether your kit is CARB legal or not. If a cop pulls you over and makes you pop the hood and sees that HKS supercharger or an intake even he can write you a ticket/tow your car on the spot and it is then up to YOU to prove that there is a valid CARB EO and have all the leg work done to show that to a court. So trust me HKS, Greddy, Hell custom T101 turbo kit it doesn't matter. If the cop sees it, and it aint stock he can write you up on the spot.

 

HKS will be releasing an upgrade... actually they just ordered one of my fuel system kits to install on their car so they can begin testing at higher power...

 

Noice, took long enough

But if I was to ever get another Z, HKS SC would be my choice for daily driving.

 

HKS has had a couple systems have a problem... but in the end you cant really compete with HKS quality... and the problems with the superchargers I highly doubt are even HKS' fault, since they do not manufacture the charger unit itself. Hopefully Rotrex or whatever they are called have got it all worked out.

 

I've never heard of them being able to tow you. Any proof to that?
Scary.

 

Fyi..The new import tuner mag has the hks 350z with vertex kit..very nice.anyways they say its doing 400whp with 100 octane gas with the new 9.5 pulley. So i guess they do have a new pulley for hks sc.

 

i like the sounds of that. thanks for the info thus far. whats the deal with the vortech CARB? i dident know that had gone through, is it just a roomer or is there actually proof?

 

If you have anything that is not CARB approved on your car and they see it they can have you towed and have your car impounded at which point they remove the CARB non-exempt part and keep it at your cost. Their justification is that the part is not legal for highway use (read any public street) and therefore allowing you to leave would be allowing you to break the law right in front of them. Unfortunately because it is left to the discretion of the officer at the scene they can be a d!ck and tow your car even if you have a CARB sticker. If that happens it goes to one of their "liscensed" mechanics who then goes over the entire car to find any CARB non-exempt parts which are then removed at your cost. If he doesn't find any cool you get your car back minus towing and impound fees. Oh yes techincally you are deserving of a refund for the fees but if you have EVER dealt with SD county for anything you'll know it take FOREVER for them to do that. Especially if they owe you money.

 

looks like I am selling my HKS

 

I've been looking at the HKS kit for awhile and I really trust HKS quality but I'm extremely put off by their fuel "solution" of adding additional injectors.

Excerpt from Corky Bell's Maximum Boost:

Some systems attempt to increase power by adding one or two injectors overall, rather than per cylinder. These injectors are customarily placed in the air tube entering the throttle body and can be pulsed by a small control box based on an rpm and boost pressure signal. As is the case with increasing fuel pressure, adding injectors is practical only up to about 9psi. This is not an ideal system, and, if used, care must be exercised in locating the injectors, to achieve equal distribution of fuel to the cylinders in a manifold designed to flow air only. [...] Consider this a low-boot mechanism.

Of course this book mainly covers turbochargers, the basic principles still apply.

 

I agree and this is a very valid point here however Corky Bell probably never cared about having a CARB exempt kit. You cannot replace the injectors and get a CARB cert. All you can do is add sub injectors.
