I heard there were some people trying to use a 350z aftermarket plenum but werent sure if it would fit under the hood. Is there anyone trying to talk a manufacturer into making one for our car. I think this is something we should start workin on asap because depending on your mods already this one mod could add as much as 20-30 whp.

 

what the hell is a plenum lol.

 

Another word for Intake manifold

 

hahahaha, if you're going to ask them to make one for your 5.5 gen don't forget my beloved VQ30DE-K

 

vq30dek already flows very well with it's stock intake manifold....

and yesss! where is our vq35 IMs at!?! the altima and maxima communities combined is pretty large...i'm sure someones gonna be coming out with one !

 

true dat. VQ30 power!

 

It flows well but not good enough. Even with the power valve removed you can see the peak point

Most maxima peeps won't spend good money for a coilover system, let alone any sort of aftermarket intake manifold or plenum spacer. For example, the new 350z manifold made by SSR is about $1000 (IIRC). Just sit tight for one made on the altima platform and utilize the design.

 

Where is this at, is this DIY? Like the TB restrictor?

 

You basically disable your variable intake for top end power in expense of low-mid range hp/tq. The power valve is inside the IM and is actuated via a vaccuum solenoid.

Its been discussed and done by quite a few people on the org

 

I don't see a point of disabling VIAS. With variable intake you get the best of both world (peak hp and low end torque) By disabling this system all you gain is a very little increase of power between 4.5k and 5k rpm but lose low end torque.

Maybe contact them and get this started, or just buy a g35.

 

Yes... First SSR, then Crawford, now Kinetix. The first 2 bailed, the latter can be found here---> http://www.forums.maxima.org/showthread.php?t=444750

. The spacer wont do any good for our cars. And some can do/gain more or the same with 1000$ than that IM can provide. But the majority of Z33 owners have more $$ than brains... Most, not all.


Our market is very small.. Alti/Maxi/Murano ... but your is even smaller (00-01) Highly unlikely for either of us, with you having much less of a chance.



I've seen very nice top end gains (200fwhp+)

 

VIAS is already open over 5k rpm. Disabling the system will not increase top end power.

 

in a 5.5 I think VIAS kicks in at 4100RPMS....so you have that extra power all the way to redline..right? why would u want to disable that to gain extra power for 500 rpms?

 

Removing the actual rod opens up high end power even more than a 'normnal' VIAS operating, but again, there is a slight loss of low end.

You don't know much about 02+ VIAS do you ?

 

thats what this website is for to learn crap duhh

 

Well then use it for what it's for..

 

idiots like you are the ones who prevent that

 

No, members who do not search bring it upon themselves.

 

You are removing a significant portion of the intake manifold when you remove the power valve.

Dynos have proven that the top end is superior in comparison to a working power valve. Ask Jclaw, Sr20den, Tilleys99, etc

 

that's interesting, but I'm not ganna do that anyways 'cause I also need the low end torque.

 

yea but them I would want cams to take advantage of extra air and adjust the power curve!!!

 

So then get cams too.

IMs can shift the powerband just the way cams do.
