STILLEN 370Z Supercharger System - Announcement!!!

weiboy718

I'm never satisfied but it is what it is and I'm gonna enjoy it!

There is still a few drivability issues that needs to get resolved. it still pings on the low end and my hot start is showing again. I'm not too worried about the hot starting, just the low end ping is what's really concerning me. I'm sure uprev or stillen is gonna fix it soon just don't know how much longer and I can't wait to get everything squared away and get the stupid carb sticker.

Q8y_drifter

is the pinging similar to a knock?

Both are forms of detonation, so in theory, yes.

How about trying some sort of octane booster to help with the pinging issues? Do you buy gas from the same place all the time?

We are also wondering the fuel he has access to as well, if not a habit in going to the same station. That being said, we should have some adjustments soon to help with the remaining quirks Weiboy has noticed. His G is very prone to tip-in knock.. which can be present on stock vehicles.. but seems to be very prevalent with his.

Wei.. switch the stations up.. and make sure it's a brand name station, and if it has been.. a different one..

out of curiosity has anyone performed any compression tests or leak down tests at all on the motors after install and some hard driving? I know that these motors are already showing signs of oil consumption here and there (not as prevalent as the older VQ motors by any means), so I'm just curious if these motors are holding up to the task.

When comparing GTM and Stillen kits please note that there are differences in kit components and this provides a huge range of variables that can change overall performance numbers, even though they're both FI, it's still not comparing the same apple to the same apple.... with that said, BOTH companies have had reputations with " exaggerating " numbers on what they claim (I have seen this with my own eyes first hand with a few FI built cars I've closely worked on). So you cannot take their claims as ammunition to compare the two really either.

what really matters is how they drive real world. dyno graphs don't tell enough of a story on how the car drives.

For example: when I had my stillen SC 350Z, it would dyno low even though I would be running 100 octane, custom stage 4 and new maps etc. BUT the way the car drove was great, linear power output all the way through to the upper RPMs etc. Sure it wasn't 420 HP that any stock motor Z could pull with a decent TT kit on it, but I had power in daily driving where they didn't. I didn't have oil temp issues like some of them did. I didn't have to worry about leaking wastegates like the older Greddy kits, I could go on and on. Real world driving is what makes a kit really shine. I can illustrate where having more power doesn't mean that the same car is any faster, in fact it can be much slower, all things are relative. Take the last generation Mustang Shelby GT500 vs the normal C6 vette. The shelby has 100hp more. yet it's slower in the 1/4 mile, any road course, 0-60, etc. In nearly every test, it's not faster if anything it's equal. Yes, they are two different cars completely, but if you're only looking at numbers and dynos (which it seems this thread is really all based on), then there you have it lol

If you really care about power numbers and that's your main selling point, save, build the motor, and go crazy anything less is a total waste. if not, why argue back and forth about numbers on paper.

Nope, still would not have.
People are waiting for the full 8PSI run so I will wait to post what they want. There will be plenty of standard GTM stage 1 builds that I can wait. I do not BS nor do I intend to sway numbers in favor of one company. I will say I was a bit shocked on the original pulls making 5PSI, but then we got down to analyzing it and found out what was going on and continue to work on it as quickly as we can.

Are you assuming you know what I want and what I plan to do with my car? When I originally talked to Sam the very first time, I told him I might end up running a 6PSI pulley with stock headers/cats just so I keep it at 400whp and no more. Then we threw in the idea of LTHs and started on a different path, and we are where we are today. No problems, nothing is broken, everything is working as intended and we hope to combine the LTHs with the stage 1 kit so everyone can enjoy this combination.

On your last paragraph, Shumby has posted his results, other G37 guys have on the other forum. I believe I am one of the first with a completed 370z kit while the others have opted to wait for the new piping instead of finishing then having to go back and change the piece out. Also, before you get all jumpy on this revised piece, nothing is wrong with the current one. Sam is improving the current design to be even better, if I never got the new piece I would never care, but he is sending me it free of charge to help all SC owners have a better kit.

You really want to start a mud slinging war RCZ, great, but do some research before posting instead of just putting the blinders on and typing. I am favor of neither Stillen nor GTM, I have owned products from both and many other companies. I buy what I want, use it, if I enjoy it or hate it I report back exactly what I have found wrong and right. We are all happy you have a working SC kit, but as it has been pointed out no one here seems to care really. You got a custom tune, are running other upgraded items Stillen has yet to test themselves and are putting down good numbers. Congrats, but lets move on past that point and look at what is going on with the majority of owners, from both sides. Stillen is still having issues with their tune and GTM customers are just waiting for a new piece to bolt down and be on the road.

Another person with no problems on his s/c, people need to STOP protecting GTM so much. I mean it is clear, that the problems werent design flawed, apparently like the GTM pipe as some are saying, its the tune.

I dont know, I think both companies are great, but as a vendor and a sales guy in general, Stillen is doing the best they can. People keep knocking it, but like most have said, GTM isnt really out their producing numbers they claim. Their is no perfect kit yet, though Stillen seems to be coming out ahead on this one now that issues have been addressed.

Good to see Stillen posting again, I personally am glad to see you guys back throwing in the comments here and there.

RCZ

+1

Stillen gets over the tune issue and the kit is perfect.

theDreamer

Wow, really?
Because I have not been on both sides here at all? Geez, you are blinded by stupidity and assumptions. I am really tired of this BS that is spotted in both threads. I could careless who has a better unit or who 'wins or loses' in this imaginary game on the internet. I picked the company because of what I wanted, but when people go around spouting wrong information, it is the reason I use the icon for facepalm.

You might want to go look at my posts again, I am by far the most neutral in any of these threads even with the ownership of a GTM unit. I really do hope Stillen pulls this through, competition is better all around and only one option can create even more problems (companies get lazy, ignore customers, etc.).

You want to attack me go ahead, but be very careful before you make a reply and re-read your own post even and as it is filled with some wrong information. Also, as a vendor I respect what you bring to this community, but maybe you should take look into staying neutral or not replying on topics like this.

Here I will help you out:

I will keep calm here, but what did I say was wrong? That GTM DOESNT HAVE A PIPE that needs to be modified, or that STILLEN DOESNT have an issue with their tune?

I am sorry, maybe you should go back and read what is going on on the forums.

ImportConvert

So...I read an article where the 370Z with the Stillen kit was tested. Ran mid/high 12's@113 and did 0-60 .2 seconds faster than stock. I did not see that they dyno'ed it.

Can I take this to mean that yes, Stillen has worked out the tune-issues before sending out a press-car, or no, they have not, and work still needs doing?

GUTCH

Only 0.2 seconds faster than stock?! WTF? 0-60 times are what I live for. Maybe I need to rethink the whole FI idea.

Red__Zed

You usually won't see a huge drop in the 0-60 time with FI. The key to dropping 0-60 times is getting traction. Before I did suspension work on my S, I would run about a 5 second 0-60 time, but trapping around 145 in the quarter mile.
