Modified Magazine did a article on mods on a 04 350z in july. part of it was this

http://www.topspec.com.au/prod49.htm

They had a 04 350z and put a carbon fiber intake on top of a 05 track lower intake plenum, 05 a grounding kit and voltage regulator, this top fuel power neo, high flow cats, UA pully hose kit thermostat radiator etc.

They said that the 05 track lower intake plenum is a new design and generates more horse power on the VQ. Very Interesting.

The top fuel power neo is a new way for me, but does it really work.

 

hmm well the 05 plenum makes more hp up top, but loses some tq


don't know about this top fuel power neo thing though, never heard of it.

supposivly some water filtration units work by rearranging the water molecules, maybe this is the same sorta thing but for gas. It's not really all that expensive so maybe someone will give it a shot. Maybe it might help against detonation? Could be a total waste of money too

 

I'm voting for "total waste of money" myself.

 

Isn't this what plenum spacers do too?

 

no
the spacers add volume

the 05 plenum has a different design for the air runners than the other version

 

Thank you for the clarification of the differences.

 

the 05 plenum on 03-04 engine di not produce any gains if I recall

 

yeah it did, above 6500rpm...hence the 2005 track engine has a 7200 redline

 

how much is that lower plenum? since my rpm is at 7200, maybe i should get one of thse too. =)
