hmmm...maybe...but it would not have the stability that we are given with pvc piping...pvc holds its own shape and hence doesn't need to be attached in many different places to keep that shape, that black stuff would need to be clipped everwhere to make sure it stayed in that shape and didn't fall down onto the road or something
Just a few zippy ties would fix that up though.
I've seen a few guys use that flexible piping, doesn't it have little cuts all along it? As its a drainage pipe? Lets the water seep in and along or whatever, if thats the stuff your thinking of, it'd still suck air, and the edges are rough aswell, so that might restrict flow a bit, I'm sure it'd work fine though.
The ag pipe was tested by autospeed (I think) and it showed a lot of turbulence and actually restricted flow. The smoother the better no matter what you use.
Yes you'd get the noise of the pod filter, but it'd get very dirty extremely quickly. A pod down there sucking from all directions would get messy quite early on I thinks. Whereas a pipe blocking off most splashes of water, dirt but still getting cold air .. I'd rather the Panel.
what if you did an intake through the bonnet and straght into the box. less piping needed making less restriction and also having less weight. not bagging the mod or anything but it seems a bit rough if you ask me. good idea though. spend the extra buck and make it look good too. then there wont be any probs from polce as it would look like its ment to be there
The longer the intake the less restrictive its being.. Hence why you can't mess with the under the guard job too much I reckon.. It's not that untidy really, so its fairly neat, and its effective because your not getting water splashes your getting fresh air from out of the bay..
Ramming the air would be good, but I can't see it being too effective when you've got so many bends up there and stocko piping to deal with once it gets through the filter.
all you would need is a dead straight pipe going into an upsidedown box which is sucking top to bottom. no bends at all. it would be the best option to lessen the restrictiveness. its just that it would be a lot of work and not a cheap option
well the ramming would help get more air through the intake when driving fast enough. Even though the rest of the intake is stock i'm guessing the ramming would help get the air through the cai pipe which is much longer than the stock snorkel and would help get the air through the air filter, from there on it's always gonna be vacuum.
* takes a deep breath *
whiplash ramming uses the momentum gained from constant airflow through the long intake to help mroe air through the front, so the longer the intake the more momentum will be gained due to the larger mass of air going through it, i guess you could compare it to driving a heavy car and a light car at a constant speed. The heavy car will take less effort to hold speed due to its momentum compared to the light car so ramming in a way reduces the effort needed from the engine to breathe the air in.
ok i guess that theory is right. but wouldnt this only be happening when your driving. so how is it different? you only get momentum when your car is moving so while ideling the longer pipe would cause for the engine to struggle to get the momentum. wouldnt it?
just did my cai yesterday and today. i wanted it to be close to perfect as possible, so for someone not really used to physical work it took quite a while to complete (very satisfying tho!). anyway i'm not sure if it's the placebo effect, but since completing, it seems the car has better low down torque. oh yeah, i have k&n panel filter also.
I used 100mm pvc pipe with the two 45deg bends. However, the pipe at 100mm is partly hidden by the bottom of the bumper since the opening in the bumper is probably only about 80mm wide. Now either i got to cut into the bumper (have seen this done looks quite trick but would be great for drawing attention to your car by the cops) or i just gotta leave it as it is. i've got a really good picture to show you what i mean if anyone is interested in hosting it. anyway, if i was to do this again, i'd probably opt to use 90mm rather than 100mm pvc pipe.
for the record, here are the tools and parts that i used:
tools:
drill (cordless and power) with varios size drill bits
angle grinder
hack saw
shifting spanner
flat screwdriver
stanly knife
parts
5mm bolts with screw tops and nuts with spring washers
silicone
500mm of 100mm pvc piping
2 x 100mm 45deg bends
100mm metal pipe bracket
matt black paint (didn't prime the plastic and scratches off real easy)
100mm pipe cap (for blocking off cai in case of severe rain/dust or whatever)
cut up ice cream container lid (made up piece that i stuck inside snorkel to block it off - photos available).
except the ice cream container, all the parts were bought at bunnings for around $30.
Well done mate. Glad to see my article being used. I'll host your pics if you want. Send them to [email removed]
100mm is good to use, but as you found out it can be harder to get in there. Now that you've done it, I'd just cut the bar maybe, I don't know. It's a personal choice I guess.
CoastVL. Apologies, I should have referenced your very well written article in my post. anyway pics will be sent in a few minutes. Thanks very much!!

i did this a while ago. i had a good pic with the front bar off but it has gone... i got a piece that goes from 100mm into a rectangle and its exacly the same size height wise as the gap in front bar and about 150mm wide...so its a perfect fit and i made it so it sits in the lil gap and it holds fine...........a very good mod for VL's
