very sily CAI idea but just wanted to know why not?

[rnbguy]

basically i was thinking why not run the CAI pipe to sit infront of the engine fan? and somehow have the fan run most of the time or when racing etc... that would provide alot of cold air for the engine right?

i know im wrong but someone lighten me on why thanx?

[EK4R]

umm...im not sure but if your running on a hot day, you would only get warm air into your cai? maybe you need a bag of ice or something handing in front of your fan

[lam.666]

the fan will only be blowing air into the rad im pretty sure (not sure on the rotation of the fan though so it might even be sucking the air out of the rad...) some1 correct me if im wrong

sticking a cai pipe just behind it will only force warm/hot air in anyway, you can place your hand there after u go for a drive and see how hot it can get.

best place would be to have the pipe in the place of the stock resonator then out to the front bar

the fan sucks air from outside thru the radiator, this means that all the air by the time it comes thru the radiator it would've heated up from its orignal outside temp making it useless in terms of CAI.

yes.
The radiator fan deals with HOT air - runs directly thru the finds of the radiator so you dont want that air entering your engine.

Best bet is something isolated from the engine bay itself...IE follow the stock airbox route down the drivers side guard etc.

right what about the a/c fan? ...

just pulling random ideas here, no need to reply if its too silly

AC fan is the exact same principle. It blows to cool down the ac .

Get the idea out of your head :) Just run a air feed pipe to the bottom of your stock airbox...

[rnbguy]

lool mmkkk

i dont wanna do the normal CAI its not worth the 0.00001kw gain for the devaluating to the car by ripping parts appart, was trying to come up with something new..

[bennjamin]

just take out the resonator liek everyone else and put in a nice hi-flow air filter ( panel one like K+N or trust etc) . then run a pipe to the bottom and you will have a nicer induction noise , and also will gain slight mid range top end "feeling"

[Xaber]

if you really want to do this idea so badly lol just buy a 10inch fan and place it under the front corner of ur car with piping running towards it and a flat panel filter. but then again i will doubt the fan will be able to keep up after a certain rpm and this idea is really just a very weak and simple supercharger and wont give mind blowing gains over just a normal CAI.

[rnbguy]

yeah nah screw it... doesnt sound good nemore ..FINE!!!!!

:)

[Kiz_EG6]

The main reason that someting like this would not work is that at any decent revs, your engine would be drawing more air in than the fan could force anyway, rendering it pointless and in the way.

That is assuming that you were after some kind of a "forced induction" effect from this, not just cooler air into the engine bay!!

Same reason those stupid electric fan pod filters are ineffective!!
"SUPERCHARGE ANY HONDA FOR 69 BUCKS" i'm sure everyone has seen them advertised.

[JasonGilholme]

I wouldn't do it cause it'd be hot air.

Ducting into the front bumper is the way to go.

[rnbguy]

yeah i gues i wasnt expecting a supercharger just a slightly better alternative to the usual CAI...

all good

[Boban]

Here's something different :p

[lam.666]

whatever u do dont do that, if you want to be different and dont want to hack the airbox and resonator

get a spare airbox lid, cut a hole then get some fibreglassing skills and make yourself a snorkel above the headlight

[TheSaint]

what about feeding a/c cool air into the intake pipe?

lol probably dumb but theoretically should be good? (prob only juss make up from the engine draw that a/c does anyway lol)

Yeah, honestly, you'd be lucky if it even did that, maybe on a stinkin hot day!
I think that the cooling is pretty efficient anyway!
If you go to that trouble you mite as well use the time to put nitros on it!

[JasonGilholme]

There are some racers that use the air con to decrease the intake temp of the air.

Dunno how effective it is tho.

[Boban]

CO2 ffs. just plumb that into the intake b4 your throttle body and you're set. I friend just bought a little eg hatch with that installed, i haven't seen it yet in person but apparently it works. It's an ex Northfield show car if anyone remembers it.


Also, i was talking with a friend, apparently somewhere in the states (it was on foxtel a while ago) they are running a eg hatch with an intake connected to the crank pulley. They have installed a fan inside the intake pipe and run a belt from the fan to the crank pulley, so at hi rpm the fan spins faster and at low rpm slower. I haven't seen it so i have no idea how/if it works, but sounds interesting.

[rnbguy]

yeah, theres probably a similar solution kept in the dark out there :)

[dsp26]

The a/c idea has been done before but not the way you think.

the cold blowing air was diverted to a pipe that surrounded the metal intake to cool the intake... then turn off the A/C prior to launch.

can't leave it on as the a/c being on would already reduce the power your crank is outputting...

so yeah as others have said don't worry about it. just heat wrap your cai pipe

"SUPERCHARGE ANY HONDA FOR 69 BUCKS" i'm sure everyone has seen them advertised.

there are legit ones with proper turbines.. however they are a massive drain on battery juice... required like 6 additional batteries in the boot to maintain 1min worth of 8psi boost... again the additional weight disadvantage outweighs any gain.... maybe a good alternative to nos though as it is rechargeable. but then ask anyone with hydraulics how long it takes them to fully charge the 1 spare battery they have in the boot let alone 6.

Besides that, how does your factory engine management go with them?
And as you are saying, you need a whole pile of extra weight.. i-i mean batteries to power it!

I guess you just have to weigh up the situation.
If you ask me, there are no real shortcuts to good power gain, spend the diollars required and put the hard work in and you will be rewarded!

yeah still tricky to tune coz such units are like aircons with electric clutch activation... usually activating at WOT on the TPS or having say a VAFC and using the vtec controller to activate the clutch... but the first method is better as you can have a seperate tune for WOT while the car runs on closed loop while not in WOT.
