The factory engine/intake/exhaust components were not designed for FI.
I am sure many people will be waiting to see more results from more sources. We are not worried about this because the numbers you see in this post were done accurately and were truly done independantly. The pulls were done on the same day, I dont even think they took off the dyno.

i do not doubt the results from their test... sounds like a very basic before and after test. Was the car even unstrapped between the tests?
phunk, I will take this to respond and let lsdunique respond to ALL the others. My "Z" was not unstrapped. The car was strapped and first pull with Kinetix V4 performed at 3:43 PM. V4 removed, NEW INTAKE MANIFOLD installed and first pull performed at 5:23 PM.

so when are we going to see NA dyno numbers? I have been holding out for this instead of the plenums....but now I am have to make all the fuel rails and everything else that is visable nice and shiny...

7: can you remove the passenger side ignition coils with the plenum installed to service the spark plugs?
Phunk, let me take this also by providing another pic. Extremely EASY to get to the ignition coils. The only thing I would suggest, if you plan on changing injectors do it before installing NEW INTAKE, as the ones on the passenger side are covered.

While I will plan to install larger injectors in the future, ALL testing was done on OEM injectors. Kinetix V4 Plenum and Intake Manifold Collector (lower) removed and "prototype" installed and dynoed.
Yeh , those runners are beggin for a row of aux injectors.
I'm just looking for alternatives to the APS "wet" Tall boy soon to be available. Being stainless , I guess injector bungs could be readily welded into the runners , one fuel rail for all six aux injectors.

Stainless would also be heavier though. Wouldn't that kinda balance out with how much cooler the temp would run? What kinda of power could you expect from this puppy?

Correct me if im wrong put this new IM bolts to the top of the lower IM and not the 3.5 heads.
As for maxima owners all the plenum makers would have to do is where the first bend starts (in the TB neck) slightly into that bend put the TB bolt on flange there and maxima people can use this. Ill prob just buy one and have a SS flange welded on because mine will use a pathfinder cable TB.
I believe maxima owners will have to buy a 350z lower (part that injectors go in,and part that bolts to heads) to make this work.

As you saw in some of the pics, my "strut" was removed for installation and knowing this was the one-and-only "prototype", requiring return to Kinetix after testing. I never had ANY hood problems. Would the "strut" have fit with the "prototype"? Don't know, however lsdunique says "no problem" with production INTAKE.

I have some questions about the manifold:
1: are your velocity stacks inside the plenum at different heights in order to make each runner equal length since some have a shorter distance to the plenum then the other 3?
2: are your velocity stacks the type where they are horn style or are they flush style?
3: what is the displacement of the plenum not including the throttle body inlet tube?
4: can you post pictures of the inside of the plenum during construction since we will never get to see in there after you weld on the throttle body tube?
5: what is the distance from velocity stack to the intake valve?
6: what is the inside diameter of the runner tube?
7: can you remove the passenger side ignition coils with the plenum installed to service the spark plugs?
Overall I love the concept and my only concern is even distribution from bank 1 to bank 2 since the factory collector is used... its original design was intended for the runners to face outward and this plenum has one bank take a u-turn to get to the other side. How is your transition from your plenum to the collector on the cylinders that take a turn back to the passenger side?
I think I might be interested in trying this thing out on my car.

In Cali , I beleive we'd need a valid EO# to pass the visual test.

I talked to Peter last night, May is the set release month.
