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).
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.

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..

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

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.

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!!!!

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.

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.

not sure what i want to do yet, going to a new tuner hills garage and see what they say. last i talked to them they had ideas about moding the pipe from the blower to the intake and moving the mafs there they said the cpu could read whats going on with the car better then mafs before the blower

since i have shelled out so much money on this car 9k for supercharger and install and 8.5k for the built motor i dont think i will be goin gtm or sts right now less i can get a good deal on selling the stillen kit

also i am not to happy with how hot the intake manifod is getting with the intercooler inside there, i cant see how the intake air is getting cooled be nice to have an ait sensor put in after the intercooler to see how hot that air is
more boost is just going to make it worse and the cpu will start to pull timing = less power

You will be in good hands @ Hills Garage I have heard nothing but good review's from Frank.

The kit does run hot and there is no way to know your IAT's unless you put a sensor like you had just mentioned after the intercooler. This is the reason I sold my kit and didn't use it on my built motor.

I agree will the maybe moving the MAFs( But we'll see- working on some things), Also I'm hope th Fron mount heat exhanger I bought will solve the heat issue.

I am going to wrap my intake pipe and then upgrade to the heat exchanger as well. I think the really good answer is to have some type of vented hood that can pull the hot air away from the engine. I have an extra hood that I am going to start cutting on to see what can be done to help correct that. Heat is the nature of the beast and trying to find a way to dissipate that heat is going to be the real answer to being supercharged or even turbo'd. Another quick fix is to add the redline waterweter to the stillen reservoir. this is shown to reduce temperature in the radiator so every little helps.
