Sorry Frank i got to disagree with most of your comments. This thread is exactly the place to keep rehashing why the Stillen SC is not the SC of choise. I believe that when the thread is bumped that the facts should be brought to light. And I in no way see how stating that so far no one has returned a GTM SC to Stillen for a swap but yet someone has returned the Stillen to GTM to get a swap is wrong. That is huge and really says alot about a company. I think people need to know this. So it was posted before so what we post somthing once then never post about it again? That would keep database space down but kill the form. This issue should and will continue to be brought up in any relivent threrad that askes about stillen. Not only does this affect their SC but every area of their business. So when people are asking about their exhaust or brakes or lips or whatever all of this showes how they treat there paying customers. So end of the Day who would you want your money to got to? A company that will not stand behind their products weather it be exhaust SC or LED's, and are willing to throw a customer under a bus to the tune of over $3000, Or someone else?

I have to agree. If we sweep this under the rug, Stillen will not change its ways. Its kinda of like the whole groupon thing where they did the add on tibet. If people complained just one day then they would have kept up their tactics of using the ad. Groupon even said that there is nothing wrong with their add. Enough people complained long enough that they finally decided to take it down. That's what is needed complaining long enough that they acknowledge that something is wrong and fix it.

I figured you would

this was never swept under the rug. Like I said there was numerous threads about this.
http://www.the370z.com/forced-induct...sc-thread.html
There is a reason why after a while threads like this get locked and that is Op said what he had to say because it loses there meaning and people just start talking useless shiz. A simple search will find all this, not like AK deleted this stuff

Good idea. As someone who has casually trolled this thread off and on to see how the development is gong. It's been very difficult to understand where Stillen is now with this product because of the disgruntled commentary (justifiably or not).

Makes more sense to split the threads: one focused on the product and technology, and one focused on support/service experiences. As someone who might consider this SC in the future, I would like to be aware of both. My guess is if this were the case maybe Stillen would be more willing to address issues on each thread separately.

wow, this thread got long!!

I see a lot of people saying GTM is the way to go instead, but you know what, nearly EVERY person lately whom I have talked to that had major work done at GTM will never go back. They lag, take forever, want endless amounts of money (up front usually too), etc etc. I know 2 good friends of mine with very high quality builds (magazine / sema cars) that pulled their cars out of GTM's shop. I'm not a fan of GTM, hence why I never took my old Z to them.

Stillen on the other hand IMO has gone downhill on their customer service front. All they want is to release a kit that is "good enough" get money for the kits, and then continue with R and D, then when they produce fixes for issues or upgrades to common problems, they want to charge EACH customer with these somewhat faulty kits more money to upgrade, so there is no standing behind ANYthing...

Both kits have promise, great promise, but the companies that are making them are what holds the potential back.

and in the end, I stand behind my thought that the VQ is a terrible motor to FI. Out of being in the scene for 7 years, I know of not a single person who has not ran into major issues with "bolt on FI" kits, and consequently full builds as well.

stay NA, the VQ will love you for it. There is no such thing as a truly reliable VQ that is FI IMO...

Who cares, all this kind of work is custom engineering. Its not an assembly line. You want performance, fine you will require added maintenance. You want to have a perfect install, fine it will require extra time. Which projects like these have many variables to them, so who care if it takes twice as long to get a good deliverable in the end. You people and think these companies can wave their magic wand and make everything perfect. This is a ridge-line business and we are lucky we have the few tuners and manufactures of these types of goods and services. Stillen on the other hand has gone about everything the wrong way.

You still don't get it. I guess there aren't many project managers here. If something takes more time than estimated it means they estimated poorly or, and this happens all the time, they estimated effort hours correctly but not duration. When a shop is juggling multiple big projects a problem with one can slip all the others. This is just reality and is all about time/project management.

What you are saying is the shop estimated it will take X hours to do their NORMAL, HIGH QUALITY WORK, but then it takes X + Y to "make it perfect"..?

I'm a little surprised people are arguing this with me, this is common sense stuff. It isn't a knock against any shop, it is just a reality of the industry. When people realize that and set appropriate expectations, they will not be disappointed.

Yep, that pretty much sums it up. At least, that's what i experienced.

I actually agree with you 100%

Do you have to pull the front clip to change the oil in the supercharger? Is it easy to do?

nope, very easy to do. jack up your car and set it on jack stands and chaulk your wheels then remove your undertray and look for the blower's oil drain line located on the drivers side. i forgot what's the size for the nut but you'll need 2 wrenches to get it open. refill is the left brass if i remember correctly. the right brass on top of the blower is the dip stick. hope this helps

is anything from stillen carb approve yet

As far as I know, there are no CARB approved SC kits from anyone yet.

what about stillen intake are they carb approve yet

Updated the original post with CARB information. Here is the link to the new thread discussing CARB approval:

http://www.the370z.com/forced-induct...ercharger.html

When any shop no matter who it is releases a kit for a certain price $X yet there are mandatory upgrades required costing $Y which are not inlcuded within the kit, it almost seems to me to be either false or misleading advertising in order to claim a low price on their kit.

Granted there are experienced people out there who would prefer to source their own upgrades. But for the average "Joe", why not just be up front and honest about the whole thing and provide an all encompassing price of $Z ($X + $Y)?

Again this is directed at all suppliers. :shakes head:

Lame kit, too much lag

Lag on a SC system? That's a first

Maybe you just don't understand

Enlighten us then

Yea am in for the enlightn us, I have this kit made good power All tho my SC failed and car is down. :(

Didnt have time to read this whole thing but tomnavone caught my eye, Did he really return his kit becasue he only made 397hp and 293lb/toque ( WHP) On their tune,, REALLY MAN I made 342 WHP 260WTQ on their tune, 42 WHP &20 WTRQ over my IE #'s.. Custom tune netted 412 WHP and 300 WHTQ, Those are their advertised 515HP, No wonder they fought with him on this, What did he think he was going to make 500WHP

This is a solid kit from what we have seen. 420whp on a mustang dyno on 9PSI. Made about 330ft/lbs of torque. Had a nice powerband really. I applaud them for taking a kit back just because the customer wasn't happy with dyno numbers. You could have just told him to go run on a dynojet! haha.

Thanks,

I've had nothing but problems with my stillen kit, the kit heat soaks so fast youll have 460 whp when u start it up, drive for a few mins in 80 degree + weather and the kit only puts out 370whp. Im fed up with the kit aswell as the car.
The overall design is weak, intake tubes, MAF postion.. The cooling system is a JOKE.
I was thinking about upgrading the cooling, new res. new piping, new intercooler.
upgrade the pulley and impeller, and MAF sensors. But why? this stuff should of been done in the R&D .
Im taking the kit out next week and replacing with a single turbo set up.
And ill never look back at stillen, for ANYTHING.
Poor design.
Thought id add, not to talk down on anyone that has stillen kit, If its working for you.. all the power to you.

Where is RCZ when you need him to talk up Stillen, and tell us how we are a bunch of idiots that know nothing. Wait he sold his too... LOL

^Haha, the stirring begins.

Heat soak is a problem with the "other" kit as well, of course... would be interesting to see some data on this

Dumb question. How are you planning to up grade the intercooler?

I am the one that bought RCZ's kit and I have not had any problems except for the crappy tune I received from WPB. Otherwise the kit does exactly what it claims to do. Granted once the engine gets heatsoaked all kits begin to loose their efficiency. That is the nature of the beast. Maybe some more than others but each car is different as well. Know as far as being able to combat this issue one needs to ensure a colder charge is sent into the engine. One theory I have is to use the current Air to water setup stillen has and add a Air to Air intercooler prior to the supercharger to give a duel cooling effect so in essance having a cooling effect before and after should lower the operating temperature as a whole.

Overall I am very pleased with the kit and understand its potential and limitations.

I'm not seeing this with my Stillen kit? It rocks!

As mentioned before, all kits will get heatsoaked. If I've been doing back to back Dyno runs I'll lose 20 - 25whp. If I let the motor (supercharger) cool down for about 10 minutes I'll make the power back immediately. Unfortunately, you're only "simulating" numbers on the rollers, so once you're on the road, who knows what power is being made / lost.

Methanol will help with the combustion temperatures, but won't help with the heatsoak on the blower. That's next on my agenda.

Well , We'll see when I'm done with my car, See sig for current numbers,

I upgraded EVERYTHING,
34 Tooth Count Jackshaft Pulley
30 Tooth/35mm Supercharger Pulley
idler assembly from a 03-05 350z
Bosh EV14 Injectors 850CC
UPREV MAF's
NGK plugs( GTR Plugs)
Heat Exchanger (Frozen Boost) 27"x6"x3.5".

I agree about the heat soak tho the way the kit is now.

Still the only CARB certified kit

Ive had my Stillen kit on for 5 months now (in the crazy midwest heat this year), and have had no problems at all. AMS dyno tuned it for me back in early May. There is power drop due to heat soaking...however every system encounters this. Actually Porsche is notorious for power loss in high heat...so this really is nothing new.

Hi there
I drive my "Z" since 15,000 km (Miles??):driving::driving:

The force is almost constant at high temperatures
(somewhat limited on the summer temperatures, as with any other turbocharged car)

I can tell you one thing:
If the STILLEN kit is perfectly matched, the pleasures are just awesome! :icon18:

Dear greetings from Switzerland

Ivo

you must have freak car then .LOL Cause I could feel mine heat soak, the acceleration is a hug lag ,, Thats why I'm upgrading my heat exchanger, I really do like the small one atteched to radiator.. :icon14:

My Stillen powered car seems to pull even better when it's warm.

Here it is on second run on a hillclimb during 90 to 95 degree weather!

Hoopa hillclimb 2012 - 370z - YouTube

lol the expression at the end are classic!

I tried to find the heat exchanger on frozen boost not sure if it will fit because I already have an auto cooler and a 34 core oil cooler. Please let me know how you find the new heat exchanger very keen to find out the results

Just a random question, You have to completely remove the sway bar while having the supercharger in? or is there a modified sway bar you can put in?
