Air Scoop

[Woodyatlarge]

I bought some weed killer last week and a hoselock sprayer to spray my weed killer,in the sprayer box there was a directional spray fitting for the sprayer,as soon as I seen it I thought....AIR SCOOP FOR MY POWERTEC KIT....

I cut a hole in it and siliconed and taped it to my 50mm flexi air feed...It works too ,as I took her for a test drive and done about 29 miles flat out,stoped the car opened the bonet and felt the the 50mm pipe running to the cone filter and it was nice and cold and so was the filter.The air flies up it....I will check in wet weather for water running up it of course.

Some pictures below.

Your 2ZZ will eat loooot of dirt

So does feeding cold air make enough difference to the engine's performance to overcome the extra drag that the scoop creates?

Im getting some fine mesh to put over the top end ,I read of this being done it cuts out some of the dirt but still alows air flo .I pulled all sorts out of standard air filters,bees wasps etc.

Could you not intergrate it a bit more into the front of the car?

It looks like it could trap a rabbit!

The scoop is not big enough to cause significiant drag ,but Im no aero expert ,usually these sort of scoops are thin and streemline but I am a f--king mentalist who cant leave anything aloneand my wife thinks I am a nutcase but since putting this induction system on she keeps lift up the gears better were as before you could do it but not as easy.My top end from about 60 mph on she is faster and more powerful ...I have had the usual warning light problems with the kit but its sorted now .My fuel economy is better..if not roaring the boxxox of it.

Yes it would be better ...Im working on it

It does look like a snow plough.

Interesting. I'm no expert either, but did wonder about doing something similar with the Celica way back. I'm not sure what the actual gain from a CAI on these engines is. In theory there should be some, but whether that's 1%, 5% or 10% I don't know.

It would be interesting to find out, but I don't know how you can measure it because a dyno can't really simulate the conditions a road, even with powerful blowers. Also not really an easy way to measure the drag, but I imagine that's a few percent.

I was somewhat put off by people saying they'd scooped up puddles and had water locked engines. I don't know how likely that is in practice though. I'd have thought that you need to build a bulkhead between the engine and the filter for maximum effect; that seems to be the way with the Gen 6 GT4s but then they can easily feed the filter through one of their spare headlights which isn't usually possible on modern cars. A bulkhead probably increases the chances of excess water getting in the system.

Good luck with it though, and if you get any test results it would be interesting to see them.

Hey guys, hows it going.

I totally understand woody, im the same, i constantly have to fight the urge to "tinker" with things on the car too. And on some small level it probably does work to your advantage having a scoop forcing air into the intake mouth.

I dont think your likely to get a waterlocked engine from that setup unless the silver ducting actually closes and seals around the intake inlet. takes a lot of force to suck water that far up a pipe and if the filter isnt actually sealed around the ducting to procide that force the water will probably never get far enough in to do damage.

I would get yourself prepared to shovel flies, insects, birds, dogs, cats and the odd small pony out of you filter now though that will suck in every living creature for about 8 feet ha ha ha!

Let me know if you catch anything exciting!!

lmao !

i think its great what hes done, all whats left is a mesh to stop the flies etc going up the pipe and its sorted. im going to do same thing or similar when i get my flexi pipe.

but maybe have two air feeds so they can sit a bit further away from my induction kit filter therefor if water does creep up it shouldnt actually touch the induction kit but thats another day another story lol

is the scoop visiable from being stood up in front of car ?

[ae102]

thats not a good place to fit a scoop - your gonna be throwing water straight at your filter. i like the diy approach - simulate wet weather driving by spraying a hose straight at the scoop.............

[Hogie]

What happens if you hit a deep puddle. Mite be alright in the summer, rite bout getting the mash. Engine bay will be destroyed without it

[Woodyatlarge]

Just to answer a few questions.

The scoop cant be seen from a standing up or kneeling position ,you would have to lie down to see it.

If I hit water puddles the scoop is in front of my front wheels so this is not an issue.

I will not be throwing water at any filter as there is a 90% bend at the bottom of the scoop.It would take alot of speed and a mass water flo to even begin travellin up the pipe it would hit the bend an bounce back .The pipe is grooved and not smooth for a free run of liguid.

Rain cannot hit the scoop directly but water spray from cars in front may do so but this will not have any effect.

And finally the hosepipe test.I turned the top of the air feed pipe away from the cone filter just incase .In got my garden hose and from 6 feet away I hosed the cone with spray first then a straight line of water at full force for a few minutes and all the water hit the 90% bend were the scoop is joined to the alloy pipe at the bottom and sprayed back out at me.

I then cut the cable tie at the cone end an looked down the pipe and there was no water anywhere to be seen apart from a few dripsat the bottom ,the bend at the bottom bounced the water back again.

In real terms if you were travelling fast with the force of the air you might get the odd bit of water round the bend ,but the cone is sheltered from direct rain and in front of my wheels and the wont be anyone in fron with a hose pipe standing hosing you at 70mph anyway

The induction kit does not suck air up the alloy pipe like a vacume cleaner,the momentium of the car moving forward catches the air coming at you and it pushes up the pipe and flows in to the engine bay in and around the cone,were the cone is able to have colder and densor air witch contains more oxygen than warmer air.There for giving you better fuel economy when driven nice and more power if you need it.

Large things like flies and crap will fall off the filter.

If it rains soon I will point the air tube away from the filter and have a look at it.

I am 99% sure that this scoop will not bring uneasy moisture to my cone ,More moisture will come in from the engine bay itself...

I am an aerodyanmics expert (cough cough.!)

the ram pressure increase you'll get from the car moving forward is significant, the reason is the highest velocity air is underneath the car. However because you've fitted that weed sprayer thing, you'll lose all of that pressure as the air has to disperse through the holes.

In my opinion you would be better off ducting that through a bog standard filter and into the engine, you will lose some pressure in the engine bay.

can't comment on the muck and water business as a lot of cars have the air intake in the bottom front of the bumper.

good effort though, can't fault you for inginuity.!

I am just tinkering with things at the moment ,But I can tell you one thing...after a journey in the car I thought I would open the lid and touch the filter and it was cold and so was the induction manifold and the top of the air scoop that points at the cone filter .The rest of the engine was hot.

So colder air is definately going up the pipe to the filter .

I would like to move it from under the car in behind somewhere but still taking a direct hit of air from the front as I travel,but the tube at the minute travels up to the filter,I am scare if I put it forward pointing that I wont have the same protection from water travelling up the tube..

[nrgizerbunny]

don't get confused between cold air and high pressure.

because you have a break between the inlet and the filter, you will lose pressure, air will still be cold, but you'll lose pressure.

I actually only drive the car once or twiice a week,my wife uses the car every day for a 25 mile commute to and from work and to leave the kids of to school and stuff.I actually cycle to work and back,she does a mixture of short start and stop and long runs.

One thing my wife has said is that the average mpg has gone from 32.2mpg to 35.8mpg on the car computer since the kit was put on the car.This to me is most of the point of the induction in the first place.

It has made a difference ,I have never drove the car above a certain speed but I can tell you now that above 60 or so she is a different car at top end .I love it ...

I am not worried about the break between the outlet and the filter but as I get cooler denser air around the filter to feed on ,to me that is what the objective is.Cooler air has more oxygen than warmer air.
