Pod Enclosure With Cai Design

[Cillham]

In all honesty is theer any gain noticed with a CAI setup for a pod?

it has the same concept as an intercooler...

turbo heats up the charged air, the cooler it comes in at, the cooler it'll leave, less work for the intercooler .. etc etc

[mad082]

but as had been said, a cold air intake that can't supply enough air may lose power over a non cald air intake that can supply heaps of air.

[Craved]

do you really see a pod system creating a Vacuum enough to implode the surrounding box?

if the feed os 80mm or more then you shouldn't see any issue..

plus most people running CAI are running boxes that are far from perfectly sealed anyway..

from the first post, i missed that its made of PVC ... i dont think it'll like the heat too much, plsu how do you propose to join the piping to the funnel etc ..

ford has been doing this since the BA in their line of XR models.

[mad082]

i wasn't saying the box would get sucked in, just that its better to suck a bit of hot air, than not enough air.

[CATKICKER]

yeah, heat shield + cold air intake! I agree, a little hot air is better than not enought air, espesially when you have a FMIC and it will be cooled anyway!

cops are pretty soft on mods down here... just hard on dickhead drivers!

[paulr33]

i dont believe there is such a thing as not enough hot air

the stock airbox and snorkel will suck in the required amount of air.

if you feel its a restriction then fit a higher flowing filter.

sucking in hot air is a bad thing

Hey guys, pretty intresting to see all different CAI systems but to spent $180 - $250 just on the CAI then + $100 for a decent POD is bit over my budget...

Im going to start researching into different materials that could be used to make my CAI design..

I like the PVC funnel idea... quite creative! would love to hear some moe ideas

Cheers

Exactly Paul! As if a custom 3" CAI with a fully sealed POD enclosure isnt going to give you a much better air flow/suction then the standard box! Of coarse it will...

Does anyone know the legal side of using a POD in NSW??? is it still a defect if its partitioned/boxed???

if it is boxed and they cannot see it, legally it still must be able to pass the EPA sound emmissions test. so induction noise is covered within that.

[QRI05E]

Thats alright then... you can line the inside of the partition/box with thin foam which will reduce the induction noise.. but i love the sound of a skyline comming onto boost lol

[BezerkR32]

At the moment it is a defect & $70 fine. There is talk about repeat offenders being punished with a demerit point. If it is modified from standard then it has to be engineered, then technically it is street legal. Depends on the cop, ive seen engineered cars get defected all the same. But id rather spend the money and get the filter enclosed and legal rather than copping a couple of fines and then having to outlay the money. It also surprises me that you would consider putting some rough looking pvc ducting in your car, $17000 plus sports cars and always looking for the cheapest option. pvc piping, $400 intercooler kits, $22 bleed valves, absolutely amazes me.

Sounds like you are some kind of mechanical engineer or something, suggest you dont post rubbish like this, makes you look stupid.

i personally would rather lose a tiny amount of power due to hot air being sucked in, than lose more power by not sucking enough air. if the cai setup will definately supply enough air then fine but i'd rather be safe then sorry.

They run a 4" intake, have you seen the standard intake on a airbox? and its about avoiding $70 fines and defects also. My customers would be pretty pissed if i fitted a pod and then he went out and got defected. What you guys do on your own cars is your business, but dont advise other people incorrectly as it will cost them money.

well everyone should know the rules for their state, so if everyone would like to post up the rulings for the different states so that people who don't know can find out.

i'm in qld and according to the 'hoon' squad up here that pulled me over, all you need for a pod to be legal in qld is a fixed mounting bracket for it.

and something i just thought about is if you have a sealed box with just a pipe coming from the front bar, and that pipe is foward facing and in the open, and if you are driving in heavy rain and following cars then you are going to get an airbox full of water. i'd suggest putting a 5mm hole in the bottom of the airbox to let water drain out. it would have to be a real prick of a cop to book you for it, and if you made it at the back of the box where it can't be seen there is less chance of the cop seeing it.

As Paul said its better to have the pod completely sealed from underbonnet air intake. The pod will suck enough air if it have a single 3inch feed. The second you open it up to underbonnet air there is no point having the cold air feed, it'll start sucking air in through the path of least resistance - i. the holes into the engine bay.

And you'll lose more power from increased air intake temps than from a slight pressure drop from the intake system. I know (at least from working with air compressors) that a 3 degree increase in intake air temp decreases power by about 1%. So it

Cold air intakes are most important at low speeds and when taking off. The faster you are going, the less a cold air intake is needed as more air is forced into the engine bay anyway. And the second you increase speed, the pressure drop across the inlet pipe will decrease due to the air being forced into the intake piping - the ram air effect.

To answer your comment, products such as intercoolers, CAI, bleed valves are all non mechanical and non electrical devices.. How can you justify spending the extra $$$ for the a near identical product that does the same job??? Fair enough the name brands might be bit more appealing in appearance but to compare a CAI costing $50 or spending $300 on a name brand and both do the same job is not logical.. and might i add there is nothing wrong with those $400 FMIC kits and $22 boost controllers..
