For example I was able to hit 201 WHP at the redline with my DEK manifold swap and VQ30DE with stock internals, only thing that was stopping me from more WHP was the redline.

That was a true 201 WHP, later on that year I was able to get 196 WHP with bad head gaskets on that hot house dyno at Maxus '05.

In the mean time, could you post the complete mod list here for clarity's sake? This VQ30 is in a 350Z (w/ 6-spd)?
So far you've mentioned:
VQ30
Nismo heads with S-2 cams
3.5 IM w/ PF TB (is the mani modified ie no shelf/power valve or is it a 350Z mani?)
Motec
Headers (which ones?)

Sorry I'm so late getting back, I was at a race in Spokane and just got back. If you can post the faxes, that would be great, go ahead. I am jammed up at work since taking a couple of days off and need to get with the dyno guy to get to the files. The VQ30 has the following:
VQ30 short block with ARP rod bolts
Nismo heads
Stock 3.5 intake and injectors
Pathfinder TB
Cold air inlet from 350Z
Motec ecu running MAP
Jerico four speed
Quartermaster 5.25" clutch
This is in a tube frame chassis with a weight of 2280# with a fiberglass shell of a 350Z

Not too much under the curve there. Another case where peak #'s aren't all they're made out to be.
Strange that power falls of toward 7k or so. So, this is

That'd be damn sweet on the highway though.

That's ok. I will be gaining more ground soon after the SSIM is finished this fall.

I'm more interested in what exactly he had to do to get a VQ30 to work in a RWD configuration than those numbers.
But on another note, whudafxup with the torque curving back up after 6500 RPM?

2 hp curves, 2 torque curves, both sets on different sheets. No one sheet has hp/tq.
Look at the readout, Max power...Max power.

It does look fishy though.

Why pay someone to do something you can do yourself? I get the phenolic for free from work. Mine won't be as pretty as Aaron's but they will still work just as well. And I have a lot more room between the upper manifold and the FSTB than most people so I will make mine thicker.

I will try to get a couple of shots of my set up. It uses a pathfinder bellhousing that bolts to a plate at the firewall and the bellhousing is bored out to fit the snout of the jerico tranny. I also used a pathfinder oil pan because I needed the clearance at the front of the motor. I cannot describe what had to be done to fit this in the frame so I will try to get some pictures. This was a fabricator's dream or nightmare depending on your point of view.

Host it from photobucket/imageshack etc, then do this with th picture location, but W/O the asterisk.

If anyone's still wondering about the two different runs, that looks like one run with the VI open and the other with it closed... crossover is even in the right place (5k).
The curve upwards at the end of the primary graph (VIAS/power rod closed) is the runners getting a "second wind" as the intake pulses are approaching the second resonant frequency of the runners. IIRC the 3.5 IM exhibits similar yet more prominent behavior, where there are two crossovers and one stage of the IM is used both in the low-mid and uber-high end of the rev range, and the secondary stage is used to fill in the valley of the primary stage in the mid-high range.

If you're talking about the Niz-Dat graphs, you're way off. He clearly said he was using a 3.5 IM. And it appears he's using a 350Z IM which has no VIAS.

Vq30 Pictures
I hope this works. There is a picture of the car, with motor in car,with custom oil pan, and a shot of the oil lines coming from the pan.
The image link did not seem to show up.Try http://www.vq35de.com/Images/Niz-Dat/

What do you mean by "stock" VQ30? That first run is 208 hp and 215 ft-lbs, and there's no way you'll see that at the wheels on a stock Maxima. Now I know it's in a Z but still, there's no way.
Are you referring to the engine only - ie. do you mean stock internals, but with modified intake/exhaust/drivetrain/standalone ECU etc? What were the mods on the car for those "stock" dynos? Which IM for starters...?

What I mean by stock is a junkyard motor from my favorite wrecking yard and bolting on headers and using a Motec ecu running MAP instead of the mass air.
I was surprised also by the numbers and wanted to see what the heads would do for a 3.0. After this season I will put these heads on a 3.5 short block I have and then run the dyno and see what it will do. I believe that there is more power in the 3.0 but I was squeezed in for some dyno time and we could only make two runs for adjusting before he had to leave.

In your opinion, what accounts for the high TQ #? I'm not attacking you I just want to know the details, as like I said, I know the engine might be stock internally but there are other mods in the picture to get those numbers, especially the TQ.

The VQ 30 that put out 208 hp is from a 95 maxima with stock intake and TB. The headers are custom by the guy that built the frame. It uses a Jerico 4 speed with a Speedway quick change rear end running 12" slicks on 15" wheels. The drive train is the same as always. I am sure the headers help the torque and I don't know if the long run from the TB to the intake on the VQ 30 with the heads helps the flow but I would say that the Motec and the ability to tune the fuel and timing is probably one of the biggest factors.
