The incorrect assumption you are making is that all the kits are well designed, and that the risk of damage only goes up with power levels.

Here is a fun nugget, one of the major factors that your ECU uses to control ignition timing and fueling is the temperature of the air going inside of it. On the Z, that temperature is taken at the MAF sensors. On the Stillen kit, those MAF sensors are before the SC compresses the air. If you've ever taken a rudimentary chemistry course, you'll know that pressurizing the air is going to heat it proportionally. Of course, the ECU has no idea that the air temperature has been raised... so how do you tune it to provide the proper fuel ratio and ignition timing? You take a guess, cross your fingers, and pray. Does that sound like a good idea to you?

I'd recommend you do a lot more research before pulling the trigger on an FI setup.

Heed the advice of the experienced members on this forum and you will have a safer, more powerful, and more reliable setup.

The stillen kit can ultimately make more power than the Gamma. But it will end up costing more as well. Im not saying stick to the stillen kit. Im saying I personally wouldnt run the kit with the way it comes out of the box.

Stillen has sold an insane amount of these kits and i think there are plenty of satisfied customers out there.These customers however dont know what they are missing out on and that they could have pretty much reached that goal with breather mods.

I also think the stillen kit is somewhat safe if you are ok paying 8K for a kit/install that nets 75-100 hp. There is no way of knowing what percent of guys have problems if you leave the kit in factory form, but I would imagine it is pretty low. Now the guys trying to push the kit over 4xx+whp while leaving the cooling the same, they have LOTS of problems.

You will want more power down the road no matter what supercharger you buy (thats currently on the market)

My best advice is get the BP kit with the comp oiless turbo. That is if your Manual, if your AT your Ef'd.

:iagree: spot on!
I would never have installed the Stillen SC before the air to air upgrade was offered.

This is the unfortunate truth. And you can buy the blower from Vortech.

Once you have rebuilt the kit to take the stock VHR motor to its reliable boosted limits, you will have replaced literally every other part of the kit. Ideally, you want your upgrade path to require as little replacing of components as possible, and this kit pretty much delivers the opposite.

Maybe one day Stillen will allow us to just buy the bracket from them - but even then the positioning of the SC is not all that great.

Or maybe one day Ill just bring a new supercharger kit to the forum that costs less than the stillen and makes gobs of power safely. :tup:

Yeah but it doesn't require a sweet hood that everyone is excited about despite not knowing what it will look like.... so :shakes head:

:happydance:

I can make it require a hood, front bumper, rear bumper and side skirts. If only I knew how to mold fiberglass....

:icon18::icon18:

As far as the gamma/GTM kit ... it's a really good setup for a supercharger out of the box and easily upgraded ... I have zero issues from mine going 2 years now ... only bad thing was the reputation of GTM before gamma took over but I think gamma is doing better now

Nothing wrong with that. Ecutek is probably the most important upgrade, and then there are numerous others from there in terms of both safety and performance.

Seb is definitely the man for tuning these things.

OP, I was like you at first and was just going to go with the stock Stillen setup. Man, am I glad these guys talked me out of it.

The Stillen tune I had was, how should I say this.......TERRIBLE. What a POS tune! The car was barely drivable. I turned the tune over to Sebastian at SpecialtyZ and WOW, what a difference!

The TopZ A2A kit I installed made a huge difference in intake charge cooling. Because I was doing a remote tune with Seb, I got to see first hand what was going on with the timing, injector duty cycle and intake temps. You could see the cooling of the A2A system working and NEVER having a heat soak issue.

Learn from what we have figured out and you WILL be a happy guy!

Alright thanks a lot everyone. After reading post about how Sam/GTM and Gamma were scamming people and vendor, I decided to stick with the Stillen.

Going to get the Stillen Supgercharger with TopgunZ's A2A kit and have a custom tune done by a local shop in Texas (JoTech). I will get the supercharger tuner kit without there tune.

Gamma never scammed anyone, to my knowledge. I don't want to dirty up this thread going off on that tangent, but feel free to PM me if you want more on the Gamma/GTM story.

I think you've made a great choice with Stillen+A2A+tune. Good luck, get a build thread started when the parts start rolling in!

Felors way to give in to peer pressure lol. JK....

These guys know what they are talking about. They guided many of us in the right direction to happiness. They are looking out for us and i can't thank them enough. You should also look into CJ motorsports fuel system down the road and talk to Tbatt about his upgraded pully kit both are a must. Good luck on your build!! :driving:

Is upgrading the flex plate (7AT) necessary when supercharging?
