Great Thanks.

I'm dynoing the car today to get a baseline and I'll dyno again once the kit is on. I am expecting to get somewhere around 210-230 rwhp now on my g35 auto sedan and about 280-305 after the install.

 

you expect too push 8 lbs of boost out of the stock headers? Do you have stock exhuast, those are huge restrictions for a boosted car.

 

Yeh, yeh, uhh Celcius that's it.Nah I'm J/K. I'm no major in physics so I can trust you on this one.I guess I misunderstood a credible reference for the intake temperatures.
Still, the IC works pretty well for its size.
I know it can't bring temps below ambient & comparing the two price-wise is a no brainer. With dollar signs out of mind, i'd just like to see the overall comparisons like: reliability,maintenence, and similar temp. ranges(if there are any similar temps.) under extreeme use & extended periods of time.
Don't get me wrong, I'm not knockin' WI.

 

Mabey he was referring to celcius. 10'C would fit right in line with it.

But yeah, I totally agree the whole system is vastly better off with the IC. I wouldn't get the SC without the stage II. If it only produced a 10'C drop in temperature that alone would be a big improvement.
I'm sure Stillen even considered putting in a larger IC but was severly constrained by space limitations. There just isn't anymore room to push the blower higher than it already is.

WI is deinitly worth trying and dynoing. I am very tempted to get the Stillen SC and try out all the above. It looks like it would be a lot of fun too!

 

Now i'm confused, and off topic, but please allow a side question. i'm currently running crawford headers, and i'm waiting to have my new longblock installed before i have technosquare install my hks sc kit. brian at ts says the crawfords will make more power with my sc over stock headers, but what you're saying seems to contradict that. i know that the stillen and hks are different types of sc. am i missing something???
thanx

 

It may be due to a boost Vs RPM relationship. The centrifugal SC don't really make boost untill high RPM. Conversly, the Stillen is working hard at lower RPM's.

This may be all it takes to lose boost during the valve overlap period at lower RPMs. In your case, you are probably good to go with the headers.

 

I just got off the phone will stillen (damn that dude talks fast), but they told me that with the headers and highflow cats that it creates to much airflow with the supercharger. This to me is odd when I thought that the guys with the 03-04 cobras put on headers and gain power with their roots. He said you need stock manifolds and cats for any supercharger, kinda sounded like BS to me but I could be wrong.

 

It double posted me......

 

I'm sure Stillen is stating the real deal when saying the blower performs better with stock headers. I'm sure they wanted it to work with their headers but if they say it doesn't I'm sure its dyno proven. They've probably dynoed that system 100+ times in development and had to of clearly seen that headers reduced midrange power.

I'm thinking valve overlap at low RPM is the culprit.

 

thanks tony. i trust yours and brian's expertise, but just to be safe rather than sorry, weighing the best-and-worse case scenarios, i've decided to reinstall the stock headers. besides, what's wrong with 80 add'l ponies guaranteed with the stock headers?
anybody wanna buy some jethot-coated crawford headers?

 

The HKS makes 80 more with stock headers?...

 

with stock headers and cats, it makes 80 more hp than stock.

 

OK.
My confusion! I was reading it differently.

 

If anyone is interested, I'm gonna slap on the new gold pulley and dyno on friday, if she goes lean I'll switch back to the red one that I have on there now, but we shall see ....

Keep us posted.
I'd like to see the duty cycle on the injector along with boost & A/F readings.I know it's not likely though.
Any additional info will be appreciated.

 

How can I log that info ??? I'm not sure I can get those readings right now ...


Colin

 

Split second can sell you the program. I believe it's the R4 software.
There are 4 screws on the black box,open it, then plug the adapter in.
It will log injector duty cycle,boost,and timing.You'll have to get a bung welded in your exhaust for the A/F ratios.

 

has anyone thought of putting a larger heat exchanger in front of the car to aide in cooling the water flowing into the intercooler? You could just go to the junk yard and find a radiator that fit in front of the Z and adapt the pump lines to it. Some one should try it as it iseems like it'd be super easy to swap them out. the system would probably hold more water too!

Where does the adaptor come from, I already have a pre-cat bung and I usually log that as part of my dyno runs ...

So you are saying that there is some kind of adaptor that will allow me to log the data from the stillen black box into the R4 software ??

Colin

 

That's right.
I've seen it done but I can't give you all the details.
