I am looking to get an S/C for my Z but cant decide. All same to output roughly the same hp output. I am looking for the best quality, no matter what the price. Another question I have is if a Stillen intercooler is compatible with an ATI or a Vortech supercharger, and if so how efficient is the combination.

Thanks

Just so you know where this thread will inevitably be moved to

 

My personal opinion, after much reading but no actual owning, is the following:

Stillen: Due to it's roots type design, it will have better low end than either the Vortech of ATI (both of which are centrifugal designs). However, in it's normal state of tune (I think 5 psi), it doesn't really gain that much power. You need to go to the 7 psi intercooled kit to really make the Stillen worthwhile. The downside is that you will need a new hood and you will loose the front shock tower brace.

ATI: Seems to be a very nice kit, but the "full" kit is missing the ability to retard timing, which seems to be very important on the Z. While I have no problem with the DFMU (it seems very flexible to me), the lack of timing retard makes me think it is best to save some money and get the "Tuner" version of the kit. Then go buy the 380 injectors and get a reflash of the ECU to set the fuel flow and the timing retard. The only downside to this is that you may need to be near one of the few shops that can reliable reflash the ECU. You can also use the "full" kit and a J&S Safeguard controller (a separate box to pull timing and guard for knock), while there isn't anything inherently wrong with that setup (it is probably more adaptable than the reflash solution) I am not a fan of the complexity. One more thing, I like the mechanical design of the S/C itself since has a self contained oil supply.

Vortech: This kit seems very nice. It has a good fuel solution and a good timing retard solution. Not too many units out there yet, but that is not surprising given that it is newly released. The only downside is that you need to tap into the car's oil supply, but I've heard some argue that this is better than a self contained supply because it doesn't require any additional maintenance. I prefer the modular nature of the self contained supply, but that is just me.

Adding one - Dreamworkes: This kit seems really cool on paper. It is a roots blower and will therefore have a very good low end. It has an integral intercooler. It doesn't require a new hood or loose the shock tower brace. They have said that there will be a full fuel and timing solution, as well as a warranty not only on the S/C but on the car's drivetrain as well. To me, this would be the perfect kit. The downside: to my knowledge no one has seen anything other than CAD models (nice looking ones though). Word is that they are going for CARB certification and the final product should be available around March (there is a post about this in the Forced Induction section).

So, if you can wait I'd try to hold out until something further happens with the Dreamworkes, but if you want something right away I'd go with either ATI-tuner/reflash or Vortech. I'm not a fan of the Stillen hood, so I'd avoid that one.

-D'oh!

 

SportZ magazine will release its Spring issue in March comparing the ATI, Stillen, and Vortech SC'ers. We should have additional information regarding the Dream Workes Racing SC kit. This information may be of interest to those considering FI for their Z's.

thanks guys. i appreciate the input

 

Hi all,

On the Vortech SC, rather than tapping the oil pan, can you use somthing like an Oil can or somthing like an engine oil cooler to supply oil to the SC.

Thanks,
Az

Thanks for the info
