STILLEN 370Z Supercharger System - Announcement!!!

m4a1mustang

If they tested it at a mid-high 12 @ 113 that's still pretty lame, though. Not too much quicker or faster than stock. Granted who knows what the test conditions were.

Its gotta be the traction, I mean this car has a good amount of torque from factory. I wonder if anyone can find out what size tires and suspension the car was running in the test??

no way you are only going to get a .2 second advantage. If the SC only make 100 hp, that should equal just under a 1 second difference. It was probably an apples to oranges compare (i.e. different tracks/time/temp/config).

How mis-informed are you? How about this...Dont take my word, why dont you just call GTM and have a conversation with Sam. I think then you would quickly realize who's "ahead". You say you like both companies...go ahead, communicate with them and see first hand what they are like to deal with...

Having an issue where the casting company adds to much material and the time to goto market is delayed due to having to hone/extrude the pipe is WAY less of an issue than the pinging/cold/hotstart/drivability problems the Stillen kit has/had...I would take a delay of part over tuning disasters any day of the week.

You've repeated this story multiple times like it proves something. What does it prove? That the guy is not a good drag racer or that he was not pushing his car hard? I mean 13.3 seconds is slower than what a stock 370z can turn with an experienced driver at the wheel. Are you implying that the Stillen supercharger decreases power output to less than stock? How does this apply to the Stillen thread?

Dreamer,
You claim to be unbiased and neutral and not promoting GTM or Stillen, but to claim that everything is "working as intended" with your GTM kit is biased and not accurate. Your kit was intended to make 8 psi of boost. You get 5 psi. Your kit was intended to make 450 hp. Yours does not, or you would have posted the results. Even if you made 400 whp you would be happy and would have posted the results - you have stated that 400 whp was your goal. You state that the fix is a simple bolt on, but a kit that "has no problems" and is "working as intedended" should not need a fix. Regardless, the fix has been in the works for 4 months and is still not done.
The truth is that the GTM stage 1 unit is just a little undersized for the 370z so that it produces good midrange power at the expense of peak horsepower. With the GTM unit, it starts falling out of its peak efficiency range when you try to push it to 8 psi of boost at the high flow requirements the engine has at the redline. The Stillen SC is a bigger unit and makes less boost in the midrange, but more in the upper rev range when the SC gets into its peak efficiency. I have headers and cats and exhaust and the Stillen kit still makes 9 psi of boost.
I make my comments based on the data. That is the idea behind being unbiased.

One guys time doesn't really prove much. I figured you'd know this with your drag racing experience. I've seen all sorts of guys with tuned cars who couldn't drive worth a .... Even if he could drive other issues could have affected his time. As others have said, track conditions, driver experience, tune, installation and traction, or all of the above, could have played a roll.

What is wrong with my kit?
Oh I am not making 8PSI because of my long tube headers, you claim you have headers and HFC, congrats but you still have major restriction which creates back pressure. Do you even know how LTHs will alter a SC unit, go spend some time on an American car forum and talk to a few of them about SC & LTHs, I did so I got an understanding of what to expect. I knew ahead of time I was going to lose boost and would most likely require a smaller pulley to bring it back up. I cannot magically wish for Sam to drop everything and provide me with my every need & want for this car, he has a business to run. We got the kit running and viable with the LTHs and wanted to see how much it altered things.

My 400whp, who said I was not at that? No one knows my dyno results but me and one other person at Baker Tuning. I will not post my results until we are able to get back to 8PSI because that is what people want. If we are unable to because the unit is to small and have to go back to a more restrictive stillen header/HFC setup then we will.

I have never said anything bad about GTM, but you just admitted it right now. They do have an issue with the pipe, but are fixing it. Also so you know since I guess you havent read, GTM was having an issue with Hot start also, so I think the misinformed person is yourself.

This post is for all:
-This forum is going down hill quickly and it seems some people wish to just tear apart companies, not even Stillen or GTM but others outside of this thread. It has become sad that since 2009 this forum has gone from great information and people wanting to try new ideas and pioneer items for this car to bitching about the stupidest things. Really it is sad and pathetic, I am at fault also for falling down to this level and it looks like people just want to throw mud all day.

What stupidity and assuptions are you claiming that Chris is blinded by? He seems to be very neutral and as a vendor (and business man) it's in his vested interest to have good relationships with both companies. I've actually been surprised by some of his criticisms of Stillen because he didn't pull any punches. For you to bash Chris because he is now praising Stillen for adressing the issues that he previously complained about is unreasonable.

Phimosis

No sir. What the people want is for you to post your results that you have now. Multiple people have requested this of you. I have not seen anyone post here or in the GTM thread saying that we don't want to see your current results. When you say that "that is what the people want", I can only assume that you mean the people that work at GTM don't want you to post your results until it produces numbers that they are happy with.

We all understand this is a work in progress. I've posted 5 sets of dyno results for my car and I report back to the forum users what the changes did, how the car worked and what the problems were. If you read this thread back to July 11 or so I bashed Stillen when I first got my car back for multiple tuning problems. They fixed them, then I posted new results and new driving impressions.

Stop protecting GTM. Just post the data.
