Well looks like I was the first to add mods to the HKS kit now AAM is working on milling me a one off pully for that kit.
So from what I see this will be the first HKS SC with a 9 lb pully.

I will keep you guys posted

 

get her done toby

 

Awesome dude. Have you thought about using a higher volume rotrex pump, or is it the only one that will fit the bracket?

 

I dont know much about that bro I am just trying to boost and stay in the safe range

 

What is the max speed that unit can run at?

and what does it run at stock?

 

Last time I talked with HKS about their future SC upgrade they said there will be no pulley change but instead a change within the SC unit (roller ratio?) for more boost. I wonder why they don't simply change the pulley to add more boost. They also mentioned adding more boost than the stock setting without forged internals will not be safe.

Funny because HKS is sending the specs to AAM so they can make me a pully. So HKS has made one all ready

 

good, please post the results, i have made up my mind to get the hks supercharger as soon as it comes out for the G35 C. I reserved one at sgpracing.com, they will be installing my kit as well.

 

That's strange... I have spoken to both the HKS Japan guy who developed the HKS SC kit and the head of HKS Japan overseas marketing department in person. All I can say is that they don't like people changing their stock settings and they consider simply changing the pulley to add more boost dangerous.

Then you got the other HKS techs here in the US that told me they're coming out with various stages on the HKS SC (probably all BS). Their software is proprietary, right? So you can only go to an authorized HKS dealer to tune your car. I get the feeling we won't know anything for sure until the product is actually out. It's crazy how many rumors there are about this HKS kit.

 

As the company that develop the kit, HKS Japan is most concerned about the reputation of the product. If something screw up and the product can't sell, the whole development cost is gone. Big issue. So say 3% failure rate, not a big number, but for HKS Japan it may be totally unacceptable and call it "dangerous". On the other hand, tuning shops have many kits to choose from so they care less about the reputation of one particular kit. Theycare more about the customer services they can offer. The goal is to use their existing resources (product offerings, experience, know-how, etc) to provide the best services to meet their customers' needs. After all people have different appetite for performance vs risk. So in this case maybe 3% failure is considered very safe and highly recommended.

For your info, HKS Japan guy also told me they position their SC kit to be a reliable and simple plug-in solution. That means to achieve that it has to be installed in a very controlled environment (near stock) and then no more mod. That's also one reason why they include F Con S in their kit which is not tunable by others. And about future upgrade, the package will likely include SC unit as well as forged internals. HKS already showed their forged internals for VQ35 engine in the recent Japan auto show.

This is very true, but as a HKS Pro Certified Dealer we are offered much more leeway. The issue that HKS USA has found is in the fuel system. Even with 1000CC Injectors they can not supply enough fuel at 10psi. With the AAM Return Fuel System, an F-Con PRO and Larger 440cc Injectors the Kit is more then capable of performing.

 

And I have the A/F reading to prove so. before I had AAM install these mods I was lean with the HKS kit on a stock motor.

 

Was it lean with the additional 2x injectors or without. I have the opposite where on the stock motor mine is quite rich with the SC.

Will scan and post graph. Later

With the stock set-up from HKS we saw a pretty flat 12.5 across the board. This is with an auto trans fwiw.

 

well, how's the new pulley?

 

update?
orginal setup not enough power for your tastes?

ANy run ins on the street?

 

Bump for update on pulley

 

Why dont you just buy the pulley? no sense in making your own They are only $65.

New HKS supercharger doesnt look like it will be sold here in the states.
