Oh goodie, hopefully we can get her done before the next track session in July!:driving::happydance:

Order two and get mine polished, I'll call you with C.C. info tomorrow the email system is not working here. Don't forget to order the oil cooler, cat-back and tranny kit and cooler as well.

:tup::tup:

I smell a good dyno comparison between a manual & auto on same dyno, same day? What do ya say?

Don't forget track numbers..

That's what I want to see :driving:

:werd:

I have a question for josh or kyle or anyone at stillen. My car is sitting at my shop with the supercharger installed but i cant take it home. Why are u changing the pully from the one u sent? Will it be the same boost as the one u used in your "extensive testing"? Will the numbers be the same as u advertised in your press release? Did u rush this kit out with out really doing any "extensive testing" just so u could have a kit like gtm does? So far very disapointed with stillen. Any answers would be greatly appresciated. :mad:

phone call maybe? or vent on the forum because your upset. They are replacing a part they may have found to be restrictive or harmful in some way it sounds.. for that be happy. If its just a pulley... no big deal. You have waited this long, may as well do it right?

Just sharing my experience with stillen. Phone call has been place but they dont have any answers. They also dont have a tune for me yet either. Their software is also locked so it cant be tuned by anyone but stillen. I chose this kit over the gtm kit because of the "extensive testing" stillen did.

I am also looking for an open source tuning application for our cars. I want my friends Audi shop to install the kit, meth, and do our own tuning...

So far stillen has been very good about customer service for me.. and also they have done well to provide fairly affordable parts with good performance. Our cars are so new i think anyone that buys some of the first SC/TT kits will deal with some issues as your experiencing... I thank you sir for helping pave the way, and hope your build finishes up soon!

Also it could be that they are still testing, excessively or not.. which should be why your getting updated parts!

If they find something wrong with there kit then, them addressing it instead of ignoring it would be the opposite of shady i would think..

Isn't boost affected by elevation? If they are shipping kits across the country, of course boost will vary.

Tom, good speaking with you this afternoon. I'm sorry that the information relayed through our salesperson, to your shop, and to you was incorrect, and caused some confusion.

The shop has the new pulley, they will be installing it and do the ECU reflash on Monday, and you'll be good to go.

Funny, my kit works perfectly. I think the pulley is just a precautionary step to keep people safe. There will always be quirks here and there as you start installing the kit on more and more cars because there are minor differences in cars and setups they are running. I find it absolutely ridiculous that someone would get mad at them for sending you an upgraded piece, free of charge, for your car to be as safe as possible. Seriously, you have to be kidding to get mad over this. They just can't win with some customers...do something about it, bad, dont do something about it, bad.

Wait what?

So because your kit is 'perfect'...How does a new pulley and a more conservative tune help with the purchase of a kit that was supposed to make XXX numbers? I mean the whole stupid battle back and forth between them and GTM was fun and all, but I think what people want to know now is, what are the new numbers and how do they compare...

I know this is the INTERWEBZ and all, but is it true 2 kits have failed and since then a letter has been sent out?

Dear STILLEN Supercharger Customer:

Over the past month we have shipped out many superchargers and have received great feedback from our customers on everything from the kit itself, the ease of installation, the quality of the components and the driving experience. However, we have also found there are variations in boost with some cars experiencing pressures higher than we are comfortable with.

As the reliability and longevity of our customers’ vehicles are our utmost concern, we are contacting all those that have been shipped the supercharger kit. We will be supplying a conservative interim tune to replace the existing tune. We are asking that the vehicles not be driven until the new tune is installed. We have released the interim tunes and ask that you install the new tune in your vehicle immediately.

Within the next 7 to 10 days we will be releasing a revised tune if necessary depending on your vehicles configuration to ensure that all vehicles will be running at top performance within our design specifications.

Please call our office Friday morning any time after 8am (PST) at 1-866-250-5542 with any questions on the process of updating the tune in your vehicle, which should be done before the vehicle is driven. Instructions for updating can also be downloaded here: http://www.stillen.com/misc/OEM_Flash_Update.pdf

I'm glad they are reaching out and doing the right thing, but I cant stop thinking about the **** that was given to some GTM fan's, and then this happens...

The kit makes the numbers at 7.9psi. It seems the problem was overboosting a little so they are doing something to adjust it back to that psi...why in the world would the numbers change? Think about it for one second... the numbers will be the same. My numbers are at 8psi and I check my peak boost every time I take it WOT to redline. Never seen it over 8.

You said it yourself, its the internet. I wouldn't believe everything I read. I hope you're not talking about Whiddles and weiboy.

dramer has driven it already. and he will be getting his offical dyno on Saturday.

I heard stillen boost has been climbing to 28PSI and blowing engines right out of the cars hood leaving it on the road. Just saying thats what i heard. lol

Dude, you got your tune done by a well known, and aggressive tuner /grats.

I asked if the rumors where true, I'm not spreading them...that is my point. I will have my kit installed, with meth, and custom tuned...Be sure I will report everything, good or bad.

The resized pulley spins the s/c slower and makes less boost, which makes less horsepower. That setup up is safer, but it is not what they advertised to the public when they started accepting deposits on the kit.

The cash flow generated by the number of preordered kits was based on numbers that looked very impressive. If they later come back and say, "well the setup we were intially selling wasn't safe, so we are going to give you a kit that makes 50% less power for the same price," are you going to be satisfied?

I think most people would not.

I posed this question/statement to Stillen's sales team: A 108 whp increase is roughly 50% lower than what I was expecting based on Stillen's press release of +155 whp. Even with the pulley revision, I was expecting 140ish. But 108?

The response received from Stillen: "Please keep in mind a couple of key points: Your baseline dyno was performed on your car as it was received at our facility - with STILLEN Gen. 3 intakes. headers, high flows and a CBE on the car. Our press release compares a completely stock vehicle with a supercharged vehicle with a CBE. A 370Z with our Gen 3 intakes, headers, high flows and CBE will usually achieve an increase of 50 HP over baseline. So if you take 50 HP from your baseline of 312 your real baseline would be about 262 HP. Compare that to the 422 and you have an increase of 160 HP. Obviously some of that increase can be from the headers and high flow cats but those two parts would typically provide 20 HP on a supercharged vehicle (the supercharger replaces the Gen 3 intakes so it isn’t accurate to account for them on the baseline). Therefore the supercharger and CBE would be providing you with about a 140HP increase not 108 as you state."

I dunno. The dyno graph is post #976 on this thread (and reposted below). It says that the power made after modification with supercharger is 422.4 whp (at 68 degrees F ambient) and before modification it was making 315.5 whp (at 75 degreesF). Quick math with a calculator says that the increase in whp is 106.9 and the increase in torque is 51.4 lb/ft

The graph with the new pully is also quite different than what RCZ has resulted from post #930 in this thread. In his dyno graph, the car reaches 300 lb/ft torque at 3,800 rpm (at 99 degrees F). The graph in my post (#976) with the revised pulley shows 300 lb/ft of torque being reached at a higher 6,200 rpm.

I suspect the difference is because centrifugal superchargers do not make make much boost at low rpm. Think of a hair dryer with it's motor spinning at 3,600 rpm (60hz ac x 60 seconds = 3,600 rpm). It makes very little air pressure. But, spin it at 60,000 rpm and it would make real boost. So I am thinking the revised pulley is killing the midrange as their press release advertises 343 lb/ft of torque @ 5,800 rpm compared to the 306 lb/ft @ 7,200 rpm seen in post #976 with the new, revised pulley, as well as the car making no increase in power over baseline at 3,000 rpm or lower.

I have posed that question to Stillen and asked if something can be done to rectify the situation. I am awaiting response.

Nope, I'm not upset what the Stillen kit is compared to GTM. If GTM didn't offer a supercharger for the 370z, I would feel exactly the same way: I feel like I did not receive the product that was advertised to me. If I did get the product that was advertised to me, I would be satisfied. This has nothing to do with GTM.

Can we get a moderator to clean this thread so we can keep on topic? It doesn't bother me that everyone's joking around here, it's just that the message gets diluted.

Thanks,

Phim

Please keep this thread on topic. I don't want to see any personal attacks in this thread. If you have a problem with a fellow forum member(s), please exchange emails and do it outside the forum.

Thanks.

Even though I was hated for it, this is the reason why I was so verbose in this and other threads. The truth will always come to light...and I now have a small sense of vindication.

our hero

OK, so it's Monday. I guess Stillen opens for business in what... 3 hours?

Ill be on the dyno in a few hours if stillen has worked out all the kinks

Lets see what gives......

Stormcrow: yes you are vindicated for being skeptical. I am a skeptic as well. I took issue with you previously because some of your posts were inflammatory and were perceived as attacks on certain people. You've been much nicer lately though. :-)

I'm hoping that Stillen will address the tuning issues and that the end product will be safe and will have an output that is in line with what they advertised, so that they are vindicated.

It does seem unusual that they only shipped a few kits with the original pulley, then very early on, pulled the kit, added a new pulley and a new tune....presumabley a tune they have tested......but then have still kept the old press release for all of their advertising material and no new press release or dyno figures have been offered.

So Im wondering if the tune and pulley needed updating because their IC isnt cooling as well as it should and they are losing power due to heat soak? That is about the only reason I would choose GTM right now, I know the FMIC works.

^^^ one other reason should be the more TQ thast the GTM kit has over the stillen

That is not the reason; I will let Kyle explain if he chooses to.

If heat soak was the issue, they would have known that early in the development cycle and adjusted pulley size accordingly. Stillen's answer was that "customers' cars have been seeing higher than acceptable boost levels."

I'm thinking that if they have been testing this kit on their developpment cars for over a year and all of them show 8psi of boost on the dyno and on the road, then they sell ten kits and customer #3 says, "hey, I'm getting 10 psi of boost, but making 25 lb/ft of torque less than what you guys advertised," then Stillen would say, "please take your car back to your installer and have them check everything out, something must be installed wrong." Not, "please do not run your car with the pulley we included, it makes more boost than we advertised. Please install this other pulley instead." They were able to trouble shoot this issue and deliver a fix before all of their pre-orders were satisfied. That indicates they knew about this issue very early on. In my particular case, I was an early pre-order (3/16/10). I wasn't informed that I would be getting a resized pulley until after the order was paid in full, the car was in the shop and the install was nearly complete (late june/early July).

That 2 as I feel thats what we really lack stock.

well I guess you can say that atleast you didnt go ut and blow up the car, but I would agree they knew and were just buying some extra time to get the new pulley fabed.

May I ask if that was your car at Stillens facility on Friday the 9th of this month? There's a car there looks just like your avatar.

There is a lot of discussion going on here and a lot of it involves inaccurate information or assumptions. Unfortunately we've been buried for the past few days so we have not been able to spend much time on here. For now I want everyone to know that we are working with Phimosis to get his car where he wants it. Our engineers made this is a huge priority and worked overtime last week and made some big gains. We will be updating everyone soon.

Phim, it was more than skepticism for me. I have had previous experiences with the Stillen products and, in turn, offered my POV when seeing the very same sales tactics and promises that lured me in and duped me. My vindication stems not from being a skeptic and being proved correct in that arena, but from being proven correct that the very same issues are created repeatedly at Stillen. I would have no issue with this company if they approached their clientelle with truth instead of false promises, stall tactics, flimsy excuses and outright untruths.

In truth, I am sorry that you had to suffer the same fate as I. But, at least you are an intellectual person who can now help other members of the community through voicing your experience. Good luck to you, sir, on getting things sorted.

..........<biting my tongue>...........he's the only one on my ignore list for a reason.

Taking bets on which kit blows up more engines over time.

I'm placing my bet on the GTM kit.

That is a horrible thing to bet on.
