People complain that nobody searches any more. Ignore them. Look at my post count...I search constantly and it's still tough to find info here sometimes.

My best advice is to just read threads in the FI section. You'll get a feel for what people are doing with their superchargers and turbos.

And if you're concerned about reliability and complexity, the Stillen SC might be an option. It's produces the least power gains but that should (in theory) be safer, the install is straightforward, and you don't mess with the ECU at all. Plus you can upgrade the kit in 4 stages if you want more power incrementally.

edit: Also, the Stillen stages 1 & 2 are CARB legal if that's important to you. No other SC is unless I'm mistaken.

 

+1 I'm also considering Stillen S/C. Sounds like it gives you decent power (around 330-350 to the wheels)

 

HAHA, no. Sounds like? where have you been reading? Certainly not here

 

Umm, quite possible with Stage 4. Had you used the search function, you would've known.

 

Saw a stillen supercharged Z (I believe stage 2 or 3) dyno (dynojet) at 295 HP, 270 TRQ during hot weather.

 

there is ONE stage 4 that made 340whp. ONE. How many more have done it? Hmm? And he had ALL bolt ons, not just the basic stage 4 kit.

Or are you talking about Stillen's in house 'testing'?

 

Vortech has been CARB legal for a long time as well.

 

Ah, cool. Thanks.

 

Again, instead of blasting others for not using search, take your own advice. Quite a few stage 4 owners are makig 330-350 whp, not just one as you claim.

As for your pathetic "well they have boltons also" excuse, thats BS. How many turbo oweners only install just the kit with no other performance mods???

You don't know what you are talking about.

 

1) show me
2) the biggest deal with the 340whp stage 4 I'm talking about, is he could only make that much power with all those bolt ons. There's no argument whether people with turbo do that or not, it's the fact that the stillen produces the least power for probably the most money for any kit out there right now.
3) show me
4) I don't know what I'm talking about? You're trying to talk someone into buying a stillen supercharger. That speaks for itself, assclown.

 

We have a G35 guy (superchargedg) in the Mid-A group with a Stillen S/C stage 4 that is putting 340 hp to the wheels.

 

i see your point. Let's say stage 4 at 340whp. Expensive kit $5204.00 intercooled. Is it really worth it?

 

you won't get 340whp with just the kit. and I think the stage 4 kit is not the same price as the basic kit. IIRC the stage 3 goes for like 6k something.

in order to pull that power, you need headers, a full exhaust, and an intake of some sort. Maybe even cams.

at least with Vortech, with headers, exhaust, and a plenum spacer or plenum you could see 350whp+ for sure.

Stillen....well.....it's a rip for the $

 

$3675.00 stage 1
$5119.00 stage 2 with intercooler
$5204.00 stage 3 with intercooler

per Ultimatez.com

 

still, Vortech can be had for 4500 or less......and makes more power than the stage 4 out of the box.

 

Considering selling my Stillen Stage 4 to go TT (if I can make the $ work). Haven't opened a FS thread yet, but if you're interested send me a PM.

 

The only issue I have seen thus far with Vortech is the sound of the unit at idle. Apparently many people with a Vortech supercharger have experienced a pronounced rattling noise at idle. The common band-aid used to address this issue is to raise the idle, something I am not comfortable with.

I am in no way bashing the Vortech, as it is my current preference for forced induction, should I choose to go that route.

 

How has your experience been with the Stillen kit? While the numbers look ok (300 to 330 rwhp), I haven't read of anyone putting down any good numbers at the dragstrip using this setup (which I find odd). The 1/4 mile times I see most often quoted are around 13.2 - 13.4, which are slower then what some people have ran with a NA setup (for example, Alberto hit a 13.1, all motor).

 

this is because Stillen does nothing for top end. All the brunt of the power is midrange torque and that tapers off pretty heavily up top. Twin-screw/roots blowers are known for this.

 

Yeah, the Stillen is more for around-town fun than drag IMO. If you just want high numbers and timeslips I don't think the Stillen is for you.
