Hey i have searched, and cant seem to find anyone with a plastic or PVC intake tube. I know i have seen other (model) cars with greater gains that use PVC tubes instead of metal. Is there a heat issue for the Z and the fact that the tube is plastic? maybe melting? has anyone tried this?
-thanks-

 

The OEM tube is plastic isn't it?

 

haven't seen any aftermarket plastic intakes...not sure what difference they would make - what was unique about the ones you saw compared to other non-PVC intakes?

It surely is, but it is also not a 3inch tube, you can keep your airflow cooler and more plentiful with a larger gauged plastic tube. you can have a non-metal 3inch CAI, seems good. doesnt it?

I wasn't asking about building an intake, I was asking if any Z owners had seen any aftermarket CAI made of PVC.
I guess ill try it myself, ill post more info later.

 

No, haven't seen any PVC intakes. On one of my old cars I ran a PVC tube setup from the front bumper to pull colder air towards the ram intake... seemed to help (yes... it was ghetto.. and one of my first cars and a feeble attempt at modding a car). You're probably gonna have to DIY on this one.

 

for *** sakes you own a Z not a honda civic, spend a little cash and buy a proper intake, seriously I dont care how cheap it is dont build a pvc intake for this car, PLEASE!!!

 

Members have made intakes out of every material imaginable. If you want to make one then make one. Its your car.

 

I'm making mine out of legos.

 

I just like to take a time out to thank everyone for their "useful" information. I was asking a question, i wasnt pointing a gun at you.

 

i want to thank bofa for atleast making an honest attempt to answer my question, I know it is not a civic, I'm not trying to be cheap, just wondering if anyone has tried pvc as a substitute to metal.
thankyou all.

No prob man.... I like to have fun sometimes too. (I blame the unfluences of davidv.)

You may be onto something.. the only way to know for sure is to try it out. I've essentially researched all intake systems that you can buy for our cars and none are PVC. If you decide to DIY, def get some dyno numbers.

 

Bofa i have quick question concerning your oil comsumption did you get any oil trip on? Also how were you able to measure the lose in the amount of oil? The dipstick is so DAMN useless... Sorry for the thread jack guys.

 

What are you talking about? How does increasing the diameter of the intake tube keep the intake charge cooler? If anything, the larger diameter will reduce intake velocity, allowing the air to linger within the engine compartment longer, and soak up more heat therein. Please provide the basis for your statement.

 

never did i say that the air would be colder by increasing the diameter, i figure that a larger diameter would allow more air, but the fact that the tube is plastic would keep the air cooler than a metal pipe. metal being a conductor of heat. I just figured that someone out there has tried it and if they have, well, then this is the place to ask right?

 

PM'd ya DremZ.

 

How is your new intake coming along?

 

another thought ~ you could ceramic coat the interior/exterior of the intake to reduce heat transfer...in the end, the power gains from reduced intake temperatures probably wouldn't be measureable, but every little bit helps.

*I've been coating my plenum w/ a spray paint that has some ceramic in it.

 

PVC? I've never heard of such a thing. The stock tube will be just fine as far as temps go. Using another type of plastic will not affect anything. If you do end up making something out of PVC, you could always add a RainBird for water injection.
