Just an overlay of my best dyno vs the fastest all motor Maxima 56k lookout
Here is the post with all the information. This shows why he is out trapping me by almost 6mph with only around 14-18 more peak whp. His times make more sense to me now...looks like the familiar DE-K power curve

OK for those who don't understand what they are looking at...
Blue line - blubyu2k2 best dyno 2002 Automatic traps 101
Red line - SR20DEN best dyno 2002 6 speed traps 106
This is just to show why his car gains so much on the top end compared to normal VQ35DE Maximas such as mine. Both are all motor and his mods are listed in the link.

The next time I dyno i expect to see the stock Maxima dyno numbers 255hp 246tq.

However I don't think 14-18whp is why he's out trapping you by nearly 6mph. If you look closely he's only has a significant power advantage from 5700-6600rpms. In 1st and 2nd gear that's pretty much meaningless. Not until some of 3rd and then 4th and 5th will that power really make itself felt and that's at speeds well above 100mph. Most the trapspeed difference has to do with your automatics gearing and drag. The gearing of the 4 speed auto isn't nearly as good as 6 speed for 80mph+ acceleration plus an automatic has no direct mechanical linkage to the motor at WOT. What's accelerating your automatic VQ is fluid motion thru the tranny which creates a ton more power loss than the mechanically driven gears of a manual. I'd imagine your VQs are pretty close from 0-70mph and you may even be quicker thanks to the torque multiplication of the torque converter, but above 80mph the superior of the 6 speed gearing takes over and accelerates the car harder on the far end. This is very typical of LT1/LS1 auto vs 6 speed cars. In the 1/4 mile they are very close ET wise, but MPH wise the 6 speed owns the auto by about 3-5mph. When I had my auto 94 Z28 that went 13.4@103mph, I owned a ton of 6 speed cars on the street and track. On the highway, I stood no chance above 90mph. It was silly how hard I got walked.
Something to consider here is your auto 2k2 would probably be making roughly the same power as SR20DEN if you had a 6 speed. We've already seen dyno proof that the Nissan autos suck out about 15whp over the manual with 4th gen guys that have auto to manual swaps. I don't see why the auto in the 3.5 VQ would be any different.

Doesn't look like Matt's loosing any lowend though

Deezo: Mine is no longer a VI.
03BlkSETE: Yes. I will get the TS ECU set to 7200+ and add more 'secret sauce' to my IM to make use of it.
As you all can see my power curve is still flat from 5800-6600 which means I am stil not peaking. There is more work to be done.

.I am trying to imagine what you have done, but I have really no idea what the 3.5 IM looks like so I am really confused.

My special manifold will be on very soon.
