AIR INTAKE MOD COMPLETE - Better than 2-hole mod?

[adz_vy]

ladz i have been playing around with my intake today and this is what ive come up with.

an aluminium pipe leading from my air box to the ground in order to take in as much cold air as possible

I, like a lot of other people dont believe in the 2 hole mod for various reasons.

As for results, i believe there is an improvement but since i dont have a dyno to prove anything ill let you guys willing to attempt this simple mod see for yourselves.

The white glue is pva to help the waterproof heavy duty tape, which was still fresh when i took the photo but it will dry clear.


>>>>>>>>>>>>>> EDIT<<<<<<<<<<<<<<
NEW IMPROVED SYSTEM

I have surrounded the aluminium piping with heat shield (used to wrap turbos and extractors to resist heat) in order to keep the air inside the pipe as cool as possible. I picked it up from an auto store for 50 bucks. I have also type of funnel to the pipe in order to flare the end of the pipe hence increasing the surface area of opening. Also added is a triple layer of mesh.

nice, mod. i'm thinking of doing the same.

thanx bud. if you need any help just let me know

noticed any difference yet? and just be careful about dirt and stuff

yeah me and my mate went for a little "drive" :P he drives a vx and we're always "side by side" but this time i was about a car lenght ahead

im not too worried about dirt ive got the mesh plus the trusty k&n filter hehe then thers also the maf so i donno how dirt is meant to get in there

ok, wasn't sure what else you had hooked to that pipe...I plan on sending my air intake to where the fan is...that way it's pure cold air

are you talking about the radiator fan? doesnt that blow back hot air?

If you mean the radiator fan, thats hot air as its just drawn all the air through the hot radiator

?? My radiator fan gives off cold air (unless that's only at idle...)

And I thought the radiator was their to cool down the engine? hence why it should be cool??

thankx, im sure i will need the help, as i am a bit of a noob, when it comes to cars.

Good luck not sucking up water with that vacuum cleaner lol. It was pouring one day when i was driving my old car (nissan pulsar) that had a pod filter setup in a similar way to yours, however the pod wasn't as low and more protected (behind fog light). Anyway, went though a puddle and the car sucked up a lot of water, started jerking and then stalled. Had to wait a few minutes before it would start again.

Nope The job of the radiator is to cool down your coolant. Your coolant reaches the top of the motor at between 90 and 100 degrees. That's NOT cool.

Your radiator is stinking hot, you do NOT want air coming into your intake from behind it

Nice intake such setups are allways worth more in real performance than just about any exhaust you can stick on the car and for the money that's a good deal. I'd be pointing to to a high pressue area of the bumper if it was me and I wouldn't be running a K&N filter with that setup unless you only drive on clean streets inside a city. K&N filters don't filter well enough to take the dirty air abuse you get from a good intake. Oiled double layer course/fine foam filters are the go for this setup. I run an un oiled K&N at the track but only at the track, it's worth about .05 over the 1/8th mile over a paper filter (about the same difference between 40 and 50 weight oil)

love the ziptie job lol but i think i shall be heading down that same path, a intake that goes straight next to my headlight at metal dead end isnt working for me.

Just wondering why you don't believe in the 2 hole mod. I did contemplate something like this but in the VZ engine bay there's not much room to extend a decent diameter pipe down to where you have yours.

If you have a look in my ride thread I've taken pictures of my MCAI/2 hole mod installation and you can see there are pipes for the radiator and conduit for cables all around the intake.

I did read a few VY V6 engined cars haven't responded well to the 2 hole mod, so if thats your reason for performing your air intake mod then good on you cos it looks like you've had a decent improvement.

I will ad the MCAI/2 Hole mod was dead easy and is well documented on JC so there's plenty of help available.

mainly because hot air from the engine gets trapped under the hood no matter where the 2 pipes are i.e. behind the headlight etc. so ur basically sucking in hotter air than you would with a factory setup. indeed ur sucking in more air however its more warm air. as the old cliche goes its quality not quantity so istead of going for more warm air i went with quality cooler air from below the engine bay. just remember hot air rises so the coolest point will always be the bottom of your engine.

thanx for the tip. i shall be checking my filter regularly to see if it gets dirty. ive been driving with this setup for 2 days now and my filter looks as clean as ever. if it does get dirty ill consider buying an oiled double layer course/fine foam filter.

interesting mod, i can see it providing better cooler air than 2 hole mod, but the risk of sucking up dirt, water, birds and kittens makes it not very practical for daily drivers, hene why the 2hole mod is so popular.

have you consider putting some flared pipe or something on the end of that tube? if you could get like 120mm inlet flared to the size of whatever pipe you have you could ram a hell of alot of air in that pipe, could alomost call it forced induction when your doing 100kmh+ lol

the hose im using is extractable and can be compressed to make it shorter, so on rainy days ill just shorten it so it doesnt suck up any water

good idea. i thought about adjusting an ordinary funnel so that it fits onto the hose

You have a point there. I had a look at your pics and you have loads of room to fit your pipe from the intake down to the bottom of your engine bay. In a VZ engine bay you would need to maybe fit a set of smaller pipes because there is no way that pipe would fit.

I might stick a thermometer in various areas on my engine bay and work out the difference in temperature.

yeah ur right, unlucky about the lack of room there but keep experimenting ull always come up with new ideas

update on my intake...
the new pipe gets pretty warm from the engine and may warm some of the air as it rushes through. to fix this ive thought of surrounding it with heat wrap which is designed to stop heat getting though. that should help.

[alien]

BullitSV6: The VY's dont have room like the VZ to do the 2 hole mod at the front of the air box. It can only be done on the side, which wont do that much and will just suck in hot air that the engine has so kindly warmed up!

Have you thought about using plastic piping instead of metal? Plastic wouldn't heat up as quickly, (although may still heat up after a long period)...And to prevent water/dirt did you look around the front bumper to see if there were any room behind vents? I haven't looked around but thought it may prevent and dirt or water
