I am not sure what that means but an update is an update I guess.
I am starting to get worried that it's been 3 months with 0 progress.
I also do not see the difference between his intake manifold and the one made on my350z.com which almost exactly the same and made little to no gains...

Honestly the big difference that was made HP wise is/was due to the sheer volume of the box that was affixed to the manifold. There are links on 350z where a n/a 350 with an open top manifold made huge gains. When they strapped a HUGE plenum on top it noted gains all throughout the range as well. The key is increasing the volume of the intake without sacrificing flow velocity.
For what the issues were with the car your talking about, we would have to know what his overall volume was AFTER, because if it came out to the same as our stock intake then you would in turn get those same results. key is the additional volume :/

"The first test we did involved physically removing the upper plenum in the middle of a dyno run, to see exactly what kind of power the engine would produce with the intake runners entirely open to the atmosphere. We found 25+ wheel horsepower. Following that incredible discovery, we built an extremely large plenum out of aluminum to see if plenum volume was the issue. No gains were found, so the next logical step was to increase airflow into the plenum. A large 3.5” hole was opened in the top of the plenum with a velocity stack that would allow airflow additional to what was coming through the factory throttle body. That 25 wheel horsepower came right back, so we concluded inlet flow was more of an issue than the actual plenum flow. The engines power output at this point was 334whp."
I still would like to know what is different about Spark's intake manifold if anything.
http://my350z.com/forum/9356326-post195.html <--Lost HP. Granted he does not have headers but a loss is a loss. His intake manifold was only $700.
I don't want to sound like I am bashing the intake I am about to buy. I really think most of my gains will be from the larger throttle body options w/ the custom TB adapter. Now will this intake produce power better than the stock intake after 6,500k? Yes, which is another reason I am going to purchase one. On a car with the stock rev limiter and throttle body I am skeptical as to the gains. Then again who with a stock rev limiter is going to drop $1100 on an intake manifold?
Glad to hear everything is progressing as planned. I can't wait to see Aaron's before and after Dyno!

youve posted alot of info so allow me to answer in a reasonable manner.
Basic idea behind the manifold: Make a SSIM that has much more plenum volume, a 3.5" elbow with a 3.5" MAF and intake to go with it. Theory behind the 3.5" piping is to make the 3" TB act as a venturi and flow better than it normally would with 3" piping on both sides of itVQ35 FWD BUILD SPECIFIC.
That sir is with the 70mm throttle body attached...Am I saying that it will not GAIN with a 90, I full well believe it will. Totally agree. We have an altima down here that is running neck and neck with our fastest local NA maxima with a 90mm tb. But ask about his driveability issues, and what it takes to control and tune that monster at idle. I called the company that made the adaptor plates to mount the 90mm to the manifolds and talked to him for a bit, and he recommended against it..>So for myself and im sure most here...75 is fine, which is the option i went for with my build.Its in my garage, along with a custom 3.5 intake with velocity stack waiting to be bolted on.
Result: This gained power starting at 3000 RPMs, all the way to redline. Made nearly 20whp peak, and right at 50whp at the 7000RPM redline.
The key difference in this intake manifold was that it removed all restrictions, or as i said in my post earlier "The key is increasing the volume of the intake without sacrificing flow velocity."
I said that up there.^

+1 I have to give you that, I have read that a million times and i always took it that when he said no gains were found that they stayed at the 25hp that they found when it was open directly to atmosphere.
[:laugh Reading owns me sometimes [i]Sadly in the case of a RWD VQ, with ivt+evt control, longtubes, cams, and a MOTEC running a 90mm TB that was the case. On ourstock ECU, No Cams, No Longtubes, and a UTEC he netted 50hp at peak and no losses throughout the power range. The dyno is there. The video is there...honestly and for our specific application.
As well i believe that the SG car is cammed? neither here nor there. Personally i would have been fine with the monstrosity of a manifold that is currently making power on nmex's car. in making changes to me SPARKS is attempting to Bougey it up so people have something to look at. kept the same internal volume, and attempted to add velocity stacks and custom runners. To ME, again this is uneducated me, we cant make a discernment without knowing what the other manifolds internal volume is.
Hell I have a stock rev limiter 
and he had a stock throttle body when he got the formula to work out on the other intake. If he keeps the volume numbers the same...its gonna be about the same result...God willing.

The theory behind the first build. Ive been on here for 7 years man...Seen alot of ****, and saw all of his posts on guessing on length etc...gotta give it to him...it worked. No other thing to say. And i have the exact same mod list as him except im auto, and he easily pegged 16hp more peak than me. take it as you will. In lookin at the difference on his car i figure if i see 15hp from the 3.5 intake/maf combo, 75mm tb, and intake manifold thats only 70$ a horse cheaper than a turbo or cams which offer 19hp
Actually it is the exact opposite. They found the increased Plenum Volume had no effect on HP at all. It was the size of the Throttle body, Intake tubing, and MAF that was the limiter. Which is EXACTLY why I am going with the ls2 to 09 TB adapter because it's pretty obvious where the restriction is...we could talk all we want about the venturi effect but we would be better off with the least restrictions possible.

I changed the MAF and intake tubing when I went with this mani. So I added a lot of fuel, it's in the thread. 12-15%, but it's not comparing say, only the mani since like I said I changed everything aside from the TB. (LRMAF, longer tube for intake, and 3.5" tube, and 3.5" V-stack, vs the JWT POP). Only thing that stated the same is the filter and TB.
$200 chipped manggg
if the flange is made for that. otherwise it will be some work.

The wiring just has to be spliced, should be easy. The 09-12 TB I am going to run and then experiment with the LS2. No reason not to go with the 5mm larger TB. Small money hopefully it's worth 5hp up top.
What is better going with the LR maf or the 3'' tube from knight? I assume the tube as the size of the lr maf is slightly smaller. With the 3'' tube from knight I don't need to change the settings on my neo because I am still using the stock MAF correct? Unlike the LR?
Edit: Is Haltech the only way to adjust our Cam Angles? From everything I have read install a cam and reving out to 8k isn't worth it if you can't adjust the cam angles. Apparently there is alot to gain there.

Yeah, me and Doug are auto, but we don't mind.
Been wanting to dyno forever. Just haven't got around to it. Dyno is 95 miles/1.5h away. So, I need to make a day out of it, (3h drive + foodz + tuning time + strap and unstrap time,etc)

Sorry to clutter up your thread Doug ...
yup.....plug is different but still same wires, just color coded different. I looked in the FSM and figured out the wiring. You need the 09 pigtail off the 09 engine harness. It works perfectly.......heres the diagram (you can see the difference in the 02 connector and the 09 connector):
That was the problem I ran into. I seen your post and it was a red ring gasket. The flange I had made is flat. I got a TB spacer fora 7th gen maxima but the holes dont line up right. Either have to drill the holes out or I'm thinking about using some gasket paper and have the shop just custom make a gasket out of that paper.
