looks quite nice indeed.

Just like CreativeDesignZ said.

Paint it black and you be good to go.

Good job.

 

nice handy work bro

 

Do you mind telling me how long the 3" piece was? Reason I ask, is I can get one made up for free at work from aerospace grade aluminum as long as I have the dimensions.

 

WHAT?

I just don't understand, you buy a $30k+ vehicle, then want to put a $10 piece of plumbing/drain material on it just to save 20-30$ .

 

i don't mind at all. the tubing is 10-3/8" total length. if you can get the offsets in the tubing that would be even better. good luck.

and i took the advice of painting the tubing black...

 

saving 20-30 dollars nowadays is a great savings, if you dont see that then you need to get youre head checked. Go flame in the various, "should i put mid grade gas in my car" threads. he did it to benefit himself and the G35 community. Finally something CHEAP that is easy and a DIY can be made. everyone else in the thread seems to think its a great idea except you, so stop reading or posting if you dont like his idea, its as simple as that. Nothing wrong with making an intake on a budget its not like hes driving a show car

 

I wonder how this would compare to the real Z tube. My thoughts is they would probably be close to the same, but the PVC pipe is probably thicker than the Z tube thus making the home made intake a tad bit narrower. I guess there is no way to know for sure unless you were to dyno both for a good comparison.

not my cup of tea, but if it works for you then I applaud your efforts.

 

^yeah Ok You Save $20, But There Is A Reason People Don't Use Pvc Piping For A Reason, If It Was That Effective And Increased Airflow And Made The Car Run Smoother Everyone Would Have A Pvc Intake....there's Alot More That Goes Into A Intake Than Just "making It Straight".

 

well im pretty sure hes the first, so he might set the standard

 

FYI...i'm 47 yrs old. i work for a major coffee plant here in new orleans. my gross income is "more than enough" to purchase a authentic z-tube if i so desired, and then some.
what i have done is not to save on $$$, but to fabricate the tube, test it and kill time mostly.

some people like to tinker. now do you understand?

 

^ no i understand, if you want to creat a tube that is awesome, but buying PVC and cuting it is not fabricating a intake. You just installed a cut piece of plumbing material...

 

He did create it, he just used pvc pipe to do so.

 

thank you.
and the tubing i used has a wall thickness of 1/16" and the I.D is the same as the 45* fitting on the throttle body, a very smooth transition. so i don't beleive there is a restriction. i haven't physically seen a authentic z-tube, but if it is made from the same material as the stocker, then the pvc is more than adequate

 

hence the "topic title"...home made z-tube.

question...what is a z-tube? clearly not a entire intake system. but just a "tube" redisigned without the air baffle chambers

 

its made from the same material...put a K&N filter on the end of that son bitch after your mass air flow sensor and you will have a home made "intake".
