The hardware can clearly support much larger power levels (enough to blow the stock engine up), but there seem to be some issues with the overall design; some have suggested the MAP placement is not ideal and has led to some of the inconsistent engine performance when ambient temperatures get colder or hot. (The biggest issue right now are the Stillen tunes, but that is not related to the integrity of the hardware)

Some people love their kit while others have had nothing but troubles, I am still considering it just for the power potential.

^^^^^ I would never use there tune it would be custom tune all the way.However I would love to see this at 10 pounds of boost T trim or 928 motorsports impeller.

I'm selling my kit for cheap if you're looking for one

I would love to buy your kit I did see it up in the for sale section.But I cant buy that right now I just bought my 370 my pockets are a little light after my down payment lol.

All good! I'm willing to drop the price for a quick sale too

Pm sent

This is funny I run from +37C TO -45C and haveto had a CEL. best one day change 25C still no CEL

No VDC works just fine with mine. It may actually be squelching the power down abit to keep the tires from spinning. Z has been very stable on all kinds of road surfaces and weather.

lmao...i come back to this site and i am hearing all kind of stuff

What do you mean?

i havent posted since Nov. i have a couple people on FB and just been viewing poeple talk down on the Stillen supercharger. Nothing new lol. But it was more than i expected.

does this set up work with an automatic 370z?

Stillen's test car was a G37 with the 7 speed automatic which is obviously the same one in the 370z and it seemed to work perfectly well. The linear power delivery of a SC will help preserve the auto's integrity at the higher power levels.

Stillens underperforming kit helps preserve the autos integrity you mean? ;)

This may be the top selling point over the GTM kit for 7AT's.

Do you have this kit? Yea didn't think so. how about you let the people who actully have the kit say things like that instead of someone standing on the out side of the glass looking in. Sorry but that was a really low cheap shot.
Frank

agreed, he needs to stfu :)

No, I prefer to buy proven parts. The Stillen kit has proven something, that is for sure.

excuse me?

Im not bashing STILLEN company but hey.. GTM has proven parts too you know?

In fact, GTM will have VVEL controller soon.. beat that if you can

oh wait let me guess, you heard stuffs about Stillen in Ebay but you never heard stuffs about GTM in Ebay? yeah thats true.. because GTM doesn't belongs to Ebay!!

Stillen and GTM are good company but you cant say you prefer "proven" parts when your facing GTM.

I have a 2009 370Z 7at with the Stillen kit and though it does not produce the numbers they advertised it does work very well and I'm very happy with it.

The Stillen kit was installed with just over 7K on the odo back in July and i now have just over 11k on this kit and it continues to perform quite well.

I took the Z into the dealership to have the oil changed and a long time mechanic came up to me and started talking to me about the kit and Stillen's involvement with Nissan performance. He mentioned that the kit was very nice and who ever installed it did a very professional job.

You can sit around and wait for somone to come out with the perfect kit with "no issues" or do like me and start enjoying a Z with an additonal 125 hp. Sure it's not what was advertised but it works very well across the entire rev range of the motor.

Satisfied

I think that went WAY over your head...

Do you have any other mods (i.e. cbe etc.). Also wondering if you are using the CARB tune. I am in the process of having this kit installed on my G37S 5AT along with the Stillen CBE with custom Uprev tune and am very curious to see how it turns out. If I get 125 hp I will be happy also, especially at altitude here in the Denver area.

Hey dal speaking of how is it going? I hope you make a installed thread here also for us 370z guys since we are still in the same family and are excited to here your results and review on what you think of the kit. If you were not planning on making one here please reconsider. PICS PLEASE =)

It is going pretty good. I got a call earlier that MAC would be starting the tune around 3:30 mountain so they should be into it by now. I really wanted to go down and watch the tune but I am slammed at work this afternoon. I will definitely post a thread over here with charts and pics when I am done. I spend quite a bit of time on this site as there are a lot of great performance related threads that apply to the G.

Quick update. MAC did not have everything they needed in the Uprev software to connect to the Automatic Transmission controller. They called Uprev late this afternoon, had it downloaded and were able to communicate with the AT controller by closing time. My car is scheduled to be on the Dyno for tuning first thing in the morning.

FRIGGING SWEET. keep us posted i am very interested. Did they take pics?

Only other mods is Stillen's Cat-Back system, other than that all stock and I'm using Stillen's Version 8 tune, which do not think is CARB certified.

It's Stillen's tune correct? You're still CARB certified and warrantied.

Nice, we have virtually the same setup except for the tune. I got the first verbal results of the dyno tuning today, 385 HP on 7.2 PSI of boost from the 9 PSI pulley. They are still tweaking the AT parameters and want to review the data to make sure the AFR is good across the whole RPM range so I am not sure what the final number will be. I will post a thread with dyno sheets, pictures and a write-up on this site when all is complete.

I ended up at 389 rwhp and to answer the previous question yes this is the Stillen tune.

Nice! It sounds like you are enjoying it based on your earlier posts.

FYI, I posted my review on this site here:
http://www.the370z.com/forced-induct...tall-g37s.html

Bump :D

I wouldn't say they abandoned it as I am sure they are watching but the min yet post they have certin people trying to attack ten and twist words said. There are people with success with this kit who gave a full unbiased review and are enjoying there kit

I do love how Stillen attacked the 370 and just made everything for it. It's always nice to have one manufact. on your car worth of stuff, ie, exhaust, intake, supercharger, pulleys, ground effects, etc. Thank you Stillen for going the extra mile, and as always, amazing looking intake mani. I am bitter about it not keeping the seperate dual intakes/TBs, but of course I know this stems from using 1 supercharger, and not twin charging.

Not a fan of the advertising style of listing the crank hp first, or at all, instead of just listing the WHP alone. It's a style choice, and I hope it's not to mislead people, and only give them more information. (I know a lot of people will think the whp seems low since they live in crank hp world when their car is stock and never dyno'd.)

To the latest post whores, stop trolling/thread jacking. Lol. Say something about Stillen constructive or not at all. You realize Stillen has to skim this thread to look for consumer questions/comments, and you are just creating a crap ton of notifications to send to Kyle@Stillen?

Unfortunately, Stillen left themselves open to criticism for not keeping forum members updated on the current status of the resolution for fixing the major issues with their supercharger tune. It seems like the hardware is good and supports a lot of power but part of the appeal with running the Stillen tune is a) warranty and b) CARB compliance. If the supplied tune cannot be made to run properly, what use is the a/b and the good hardware? There are a few that have custom tunes which have yielded great results but that doesn't help those who need CARB certification or want the Stillen warranty on the kit.

Yes, there is some soap opera in here but for those considering the kit or those who own the kit and are having issues, Stillen should have been more attentive in addressing questions and concerns on here and that is what many people have an issue with.

This response is to Fezzik. This is the link to my origiinal gripe. http://www.the370z.com/intake-exhaus...entions-2.html

To add, Stillen provided no additional response to my inquiries. Since that post, I had the stock tips fabricated to the Stillen exhaust for $400.00. Well worth the price to remove the misaligned-mismatched design theme. It also reduced restiction that was in the Stillen tip.

do I have the right to talk all the crap I want since I had their kit but removed due to it not working correctly?

You already said this in previous threads that you made. Kit didn't work out for you and people know this. Do I feel they should have taken the kit back, yes for both your guys sake. I am just saying all this was already said and how many times we going to keep bringing the same old shiz up again.

We all get it that there was some tunning problems from stillen. Alot of the people that had problems came on here reported it and disapeared to not tell us the resolution of it. To me that means they got the situation fixed and are now happy with the kit. If they were not they would still be on here telliung us about it. Also like I said there are people here who gave there honest opinions about the kit and they are happy with what they got. All the info is there on this forum there is no point in beating a dead horse with a stick because it is not getting anything acomplished or satisfying any problems. All this info is oput there, people said what they had to say, let the consumer decide what is best for there car.

For the record Frank I don't doubt Stillen or Vortecs products, based on past experiences and stories I don't think their tunes are where they should be... Obviously people like RCZ and Dal are quite happy with their products...

I think constant criticism from customers is what is needed to get companies to change. It's not like Weiboy is spreading false information.

Never said he did and didn't acuse him of doing so. My point was criticism was already givin he said what he felt and gave the community true information of his experiance. There was a few threads and post about it. People just purchased this kit and are having good experiance with it so far and they don't need people running around bashing what they just spent there money on. I hope you understand what I am saying since I can't find another way to put it other then weiboy already posted his experiance a few times no need to keep repeating it and re-taking the trip down memory lane, causeing an uproar and also having people that didn't own the kit bashing it.
