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).

What article was this?

The guy in Canada ran a 13.3 with his stillen SC.
Chris and I watched the run. It was in a G37. 6 MT.

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?

:iagree:

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.

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.

Talking to a company's chief promoter is the easiest way to become biased. Looking at all of the data is the way to make the most accurate and unbiased assessment of the situation. This is what Chris is trying to do. Stating that he is misinformed is insulting.

If you want to call things like difficult hot starts a "tuning disaster", then then GTM has a tuning disaster as well. The tuning problems that I initially had with my car were not issues that could lead to engine damage or failure. Those issues were fixed long ago. My car has been running perfectly since September. GTM has had a problem getting their kit to market. Once they start getting more cars on the road like Stillen has, other problems - like GTM's hot start issue - are going to show up... Just like they did with Stillen. Then GTM will go back and fix those issues, just like Stillen did. GTM's mass deployment of the kit and the surfacing of problems still has not happened. They have two cars on the road (shumby and dreamer)? Stillen went through that process in June. Implying that GTM is "ahead" of Stillen is simply not accurate.

yeah i painfully read through all the threads before i dropped off my car at GTM..i dont have anything personal against Stillen or their products but honestly i was turned off by the negative reviews and lack of response from them..after taking Sam's car out for a test drive it was pretty easy for me to make the decision..

Reading all of that was kinda painful. Is there an update from Stillen with the tuning software or are we still in a holding pattern?

Turbo here I come...

WOW lol. Here is my opinion but then once again I know no one asked for it. First off I agree with Phim on the one subject. Dreamer I think you should post your results of the Dyno. Everyone knows that you are a test car in the sense of being with the headers and all but thats still valuable info the community can take in.

As for the GTM kit I am sure it can make 8 psi but it seems the people that have didn't want to go that high due to not knowing how there components would hold up or because they are testing things out to see what they can put on there cars to get it to work. As for the pipe that GTM is having to fix, that is a manufacture defect from a company GTM pays to do there pipe, not a reflection on GTM imo.

Now as for Stillen they have to really get this tune **** figured out. I don't think Stillen fabricated there numbers either as far as Dyno wise when they did it with there test car. I really think the car put that down. The part that gets me upset with the whole Stillen thing is that people have been unable to drive there cars now for 4-5 months. Also seems like the only way to go with this kit is custom tune and I think Stillen should help people get that and after they get there carb legal tune down then send it to others that want the carb kit. Blame situation taken care of and no one would be here wanting to rip others heads off. As for all the stuff floating around on the forum about the stillen kit. I only blame Stillen for that since they let us as a forum determine what was fiction and what was fact because they didn't come on here and give us a detailed explanation of what was going on.

I am not bashing Stillen just giving my opinion. I have nothing against them in the end and I am actually looking at them since I want to put a SC on my xterra, I just don't like how this whole situation is being dealt with. As for which kit is better I don't know because I don't own either one of them but I think if I was going to buy one I would be leaning on the GTM side just because from what I can see, is there customer service is better.

Phim as for numbers wise I think you are just going to have to wait for Danny to see what he puts down to compare which one is making more power. I know he is running on a canned tune from sam.

All forums go the same way eventually - makes for an amusing read when bored.

I am stuck away from home often and stuff like this keeps me smilin, now I got to thank everyone for that... ;-)

:hello: Come on in.. the waters greeeeeeeeat! :tup::driving:

:iagree:
He's telling the truth :driving::happydance:

In everyone else's defense, you are in the Stillen thread yet have a GTM SC. I'm at a loss as to why GTM guys are in this thread, and vice-versa for that matter. It's a pissing match from both ends.

I agree, the forum is going downhill quickly, and that is because everyone is pissing at "the other guy". I'm still trying to figure out why. Has everyone become nothing more than a fanboi?

hah.. nothing wrong with a good passionate debate. Long as we get to the bottom of things that is. And no one is hurt in the process :icon17:

Looks like i will continue to wait on progress, by spring time would be nice /wink. I would like to see the Stillen kit get its tune worked out. I really like how the look turned out in the engine bay. But function over form for me in the end. -Edit*

I guess the only real question now is... Redo my home theater or.. Diffy/gears/clutch/flywheel haha...

Hey, guys, been working solid lately. On Vacation, now.

Now about HP numbers:
Kind of stings a bit, Uprev had ziltch for me, so I am going to Houston this next week and placing the Z on a Dyno. Let 'er rip. Hopefully have some cold hard facts to show. Place is called Carboy on Westheimer Drive in Houston.
Going in with stock exhaust system, carbs and headers. I don't have the fancy stuff RCZ has. But I do have a custom tune which seems to me very impressive. I was told the SC is ok with the stock 2.5" exhaust I have, only if I don't like the sound.
The SC is running well right now. Changed out the Vortech fluid as recommended at 2500 miles. Next interval is 7500. It seems that the more miles I put on it, the "smoother" it is getting. The blower still rattles a bit at idle. The signature "whistle" is neglible at normal highway speeds. I can't hear it. I finally broke the tires loose with VDC/Traction control ON today doing a turn onto a nice straightway. Felt great. The 7 speed Auto is just so fast! Forget it in Manual, I'm too slow. The Z is still smooth when passing somebody. I love that about this car. Just a slight depress on the accelerator and in a heartbeat, I'm in front! So much power here, I don't have to step on it at all. Oh, yeah and in a 25 mph headwind! I gotta tell you the Z drives far better than other cars (ok, especially the cube). Stiffer steering, finer control in the curves and low center of gravity. Oh and gas mileage has improved, too. Getting an extra 4-5 miles to the gallon. Averaging 30 mpg driving 70, for a fair number. So, yeah I have a happy ending to this story right now. Hope everyone gets theirs!

I've done lots of business with Carboy and I've always been happy with their service. They even cut me a deal back in the day when I was struggling a bit with finances. I'm half tempted to swing by and check out your car on the dyno. :)

Once I lock down a time with them, I'll send you a message, either way.
Definitely get all your questions asked, heck, it will finalize a couple I have too.

Whoa, for sure man. Thanks. :) I really just want to hear that thing scream on the dyno.

hahaha, makes me laugh. I think we're spoiled with the 5.0.

Can't wait till mine gets in...

Glad to hear good things about the kit again, go figure custom tunes and perfection. I do find it funny(watch the fan boys come out now), that someone installed the GTM, and now their is a fluttering noise that they havent figured out. I guess the all perfect gtm, isnt as perfect as it seems.

I am sure with time itll get fixed though, just like the stillen issues are.

Twin Stillen Supercharger

TKF racing Stillen Supercharger

Insanely nice looking ride ^ PW

Omfg hot! ^

Not sure if it was the same article, but I read 0-60 in 4.5 secs, and that's 0.7 secs quicker than the stock 370z previously tested by the magazine. 12.8 @ 113 for the quarter mile.

I don't think stillen had tuning problems w/ their press car, just certain ECUs.

The test car had KW V3 coils, Stillen rear sways, AP racing brakes (6 front 4 rear pistons), and enkei gtc01 19s w/ 10mm wider than stock (255 and 285?) toyo r888 tires.

The article did mention that they "predict better numbers are possible with less camber than what came dialed into the rear of [their] test car".

The one I read is Road and Track, 12/2010 issue.

THat 350 needed 2 power adders to hit 444whp?

Dyno Results
 

4th Gear: 352.4 Rear Wheel HP, Torque 293.2
5th Gear: 375.7 Rear Wheel HP, Torque 300.8

I was told to get Engine HP divide by .8

4th: 440 HP
5th: 470 HP

Did three runs and the best of the 4th gear run we kept
Each time we got to 160 mph, 7500 rpm got the electric cutoff, it was starting to flatline anyway. The Fuel and Air looks good all the way through.
It was 61 degrees outside. Oil temp never got above 250F
I asked how the Dyno itself was calibrated and the Tech told me it was all done through the software. I asked how often the big wheel is greased up and he said every 6 months or by hours whichever comes first.
Running Super Unleaded, Stock pipes, no oil cooler, just skin and bones.
Hopes this helps anyone else.

Test

That might work randomly for random engines, but it's not going to be consistent nor does it work mathematically.

HP = [Torque * RPM (at given torque value)]/5250

Yes. It looks to me you are right. This one is for Rotational Horsepower.

Lowers my Engine HP numbers by about 40 on each (if peak is 6700 - 6900 rpm).
Some could consider Horsepower is actually obtained in a quarter mile run matched with the weight of a car and how fast it is going when it hits the trap in real world conditions.

HP = weight x (velocity/234)cubed. The Dyno is Static.

Thanks for the post on that. I don't know where the Tech guy got the .8
I bought it though.
