Funny cause I was waiting for same also, But what dyno do they use? Dynojet? So my 412 would have been more like 450ish WHP and 330's WTRQ. :)


Also let say?? 1 psi will get you approx 6.8% extra hp over a naturally aspirated setup (again, theoretical).

330HP VQ ( 6.8 %) is 22.4*9 PSI =201.96 HP over stock- 531HP so 412-430 Dyno depending and some other Var's WHP. So adding 4 PSI( 13 PSI) to my set up should net me 621HP /20% drive loss Should be 497 WHP , (again, theoretical).

Please do not turn this thread into gtm vs stillen,

GTM and Stillen both have durable kits....

Even if our kit was CARB approved, I still would not be able to offer you what you are looking for. The minute you buy any CARB approved kit and you make any changes to it whatsoever (Custom tune, different pulley, etc.) that approval is void along with the warranty. In order for you to keep the CARB approved status and warranty, you cannot mod the kit. From your previous post in another thread, you are already talking about modding the kit so your point is moot.

I'm not really sure what the regulations are in New York, but if the regulations are like a lot of other states that only check the OBD II or even a sniffer test, then our kit will pass with flying colors. Even in California, they are talking about new regulations that will be testing cars through OBD II only and doing away with the sniffer test altogether.

The bottom line is that you can either buy a kit that makes 500whp out of the box, or buy a different kit that you have to mod further to maybe (and that's a big maybe) make 500whp.

I'm not following your ricer math, but I commend you for trying. :)

You definitely have an uphill battle, but if you don't try you'll never know and I'll give you credit for that.

My biggest concern will be how will you tune the car properly if you're never able to tell what kind of air intake temperature your engine is ingesting. You would be better off going back to the stock intake manifold and running a blow through MAF setup after an air to air intercooler. That way, you won't max out your MAF's and your ecu will know what the hell is going on. Even when Vortech designed their supercharger kit for the 350Z, they were smart enough back then to do it right and use a blow through MAF setup along with an air to air intercooler.

Sam

I have to agree with this.

It is hard to believe that Stillen didn't really learn much from the horrible F.I kit they have built for the 350z. Using a S/C that a 1.6L honda would run on a 3.5L V6 engine..:shakes head:

When I saw the 370z kit, I thought it was a good supercharger (head unit), but then they went ahead screwed up EVERYTHING else.

AGREED!!! Let's chill out and respect the guys build up.

No problem Sam, I knew you would get a kick out of that! LOL.

I upgraded the MAF's with the UPREV ones so I'm not worried about maxing them out. Al tho I do kinda agree with the moving the MAF's after, I was tossing this around( having pipes made for the Stillen intake) but decided for now to stay with the Stillen design.

The thing that is really hindering me is there is "NO ONE" around here that could make the pipes- Heck I had to send my intake to FL and S&R for them to trace it.. IF I had a local place that did the custom work , I would drop the car with them for one day or so to make the pipes and move the MAF's. But having to send things out to far away places is not comfortable for me. I have to call and fell like I'm bugging guys when the place is not local for me.

Agreed with Sam on this, Again the GTM kit or Stillen kit should pass the inspecting Sniffer test as long and as long as you have you cats you should be fine( ALL THO there was a goofy thread here that said it you have tune you would FAIL).. GTM's kits are proven OTB to make high 4'-500WHP, An again I almost went this way but the "Dealer offered my Factory warranty stay- if they installed it and I used Stillen's kit- The dealer is a Vendor for them). Yes I have this in Writing- But to stay on topic, GTM and Sam's kit's are proven 500WHP kits, Mine will be a UM lets see. But this something I did to be differnt and really wanted the Factory warranty,- Especially casue I have a 2011 and when this started it was under 9k miles.

But if I had the choice , I proably would have went GTM- But the had no X kit whem I went FI also.. :(

You did what you wanted and needed to do. You had your reasons. Nobody can fault you for that. Enough said. ;) I'm waiting to see how this turns out. Because I may follow the same route, or wait for the twin SC's from GTM.

ANMVQ. You can always buy a spare intake pipe from STILLEN and send off your old one. No down time there for sure.

ANMVQ I also am going along with this kit because my Nissan dealer told me that they would still grand warranty to my 2011 12,000 miles on my Z. So I guess it's still a win win.

I wanted to throw this out there if you need something from S&R I am in tampa and could always drop by for them to take measurements or the such. In fact I am leaving for overseas for a couple of weeks come the first part of Sept so if they needed it for a while they could use mine without downtime to me since I will be gone anyway.

Hey Kelly, THANX man really a lot. S&R ( Jose) has my intake now. I sent to them last week. But I may take you up on that, I was still tossing the idea around of moving the MAF's but wont know till after the 25th my retune date. Maybe between now and then if you really have time just swing through and have them measure and look at the the pipe after the SC to the intake I can talk to them over the phone and see if it something they can do for me.. PM me an I toss you my cell #. Thank a lot man!!!! :tiphat:

WEIBOY, Thanx man, the Stillen intake is at S&R now. Car was down for the SC issue , Was talking more going forward, But maybe with Kelly's GREAT offer I may avoid this.

:( Tuner will be a real time attach on the 25th( Just texted me) So the 27th now..

The wait should pay off. Lol
