Electronic Light Pressure Cai

ALO GUYZ... i already makes some eksperimen on my car.......electronic light pressure CAI..huhuhuhu....the result is better....it is good... well so good.....come take a look some pictures.....hehehehehehhe

looks great,isst really work, i mean in term of power improvement..coz previously saw sumone done this but using the fan to swirl the air coming through,but thi fan using power,hope it be more improvement...wanna ask,if the air coming through in high velocity,didnt it disturb the fixed speed of the fan???hope u understand my Q..thumbs up,creative..

 

[SkYwAlKeR]

why not u connect the CAI hose directly to ur stock airbox so the engine sucks cold air directly from outside... no need use fans to blow cold air in...

jz my 2 cents... vr creative idea of urs.... malaysia boleh... haha...

 

[mohdashraf81]

oooo....no problem as long as there is no leak on the hose..even you dont switch on the fan it still will make the fan turn when yourRPM around 3000, this is because the air inside the hose will be a vacum and will suck everything in to it...and this will make the fan move according the pressure that the carburator suck the air....if your RPM at 5000 -6500...the fan will go extremely fast..... the switch is for when you in race mood... when the car is stand still... there will be an air because there is a fan inside it... even the fan is small but there is 3 fan inside it so the air blow is good....so you get an-extra air even you car not moving this is for pickup at first gear then come to second gear the fan is already moving and vacum suck the air that makes the fan move more quickly....and so-on.....

 

[mohdashraf81]

the fan is for to swing the air in the airbox....its light a surbo..system...but surbo doen't have fan...hehehehehehehe.... malaysia bole.!!!!

 

[whatdamn]

just a point: the suction of the engine will outweigh the suction done by the small computer fans regardless even if u put 10 in a row.

 

[edwin_lcw]

for me causing more air restriction ..... doing CAI is the best ..... just my 2 cents .... anyway good job u have a nice hand work ....

 

[SkYwAlKeR]

yeah, air restriction still do come into my mind.... if u are moving at low speed, it might help... but at higher speed with higher revs, it might face some air restriction problems...

 

[mohdashraf81]

so there is some air restriction at higher speed la......but it seems there is some improvement on my pickup.....and you can hear air when it being suck....anyway it is just an experiment.....or just a prototype right........but im happy with it..hahahahahahaha malaysia bole!!!!!!!!!

 

[edwin_lcw]

i had this idea long time ago ..... last time when i work in the factory i seen exhaust that has a fan behind i mean in the pipings before it goes out to the muffler ..... is like a fan spin using ball bearings ..... i wonder if we use that fan to suck air since that fan is running freely not using any motor but ball bearings

 

[mohdashraf81]

waaaa....thats got idea......im trying to find a ball bearings fan to replace with this fan .....so the fan can move more freely but the fan cannot be so big la....it will be like a turbojet.... is like a small silinder fan with ball bearing .... i saw at accessories shop at RM300++.... so can anyone suggest if there any ball bearing fan at a size of computer fan.....???

 

[DarkAccoon]

just go to jalan pasar there and u can find those fans
will be using 12V and also has a variety of size
be it 80mm or 120mm
can also choose either ball bearing or sleeve bearing
kinda cheap also, about RM 20 something

last time i did the same thing but with different method.

i bought a 12v vacuum cleaner.. seal all the air holes/leaking with silicon paste. so just leave the air in and out the vacuum. i also cut off any parts inside the vacuum that will restrict the air flow inside vacuum (theres a lot actually). then i take out the on off switch, sealed the opening with silicon too (the good thing about silicon is it will not change shape or melt due to the engine heat). before i finalize the sealing, connect a long wire from the vacuum motor (extend the vacuum cigarette lighter plug wire) into my car, so can control from inside my car when drive. the vacuum air inlet i glued with washing machine hose, extend under my hood to the side hood opening gap. another air outlet also with hose to the airbox (i poke a hole at the airbox and glue securely).

the air pressure is great! really a good start in gear one! do not bent the hose in ur engine bay too much! the sound air sucking in before u start is awsome. dun worry when u gain speed as the air pumped in wont interrupted by the air from the stock airbox. infact, the air will keep ur airbox cool!

hint:do not turn the vacuum cleaner for long period. suggested is 10min max when moving. the motor might burnt!

happy DIY !!

 

[SkYwAlKeR]

waa.... going to be kinda like a mini turbocharger adi....
yeah, this is how turbocharger works... they force air to enter using fan blades....

bravo, u'vr jz created a microturbocharger... can sell as a product and say it saves petrol adi... hahaha....

 

[mohdashraf81]

hehehehehe...good.......i wil try it.......tengkiu...tengkiu.......any other suggestion.....

 

[Izso]

Too much air and not enough petrol oso no use la kawan. Later you get pinging or something then you die. Unless you got one really smartass ECU that'll compensate the extra air with more fuel being fired, you'll just get the same fuel injected + more air and that does not equal more power.

 

[mohdashraf81]

to much air......so if using the 12 v vacum it will give to much air.......but that if the car is fuel injection.....carb??......also same ka?....which one is the PVT hose??.....anyone knows PVT hose on iswara???

 

[fritz]

Izso got his point..extra air but if the fuel is injected as the same..how ar? any sifoo explain?

 

[ocphangaz]

fuel injection ke or carbie ke... still the dc fans are before the throttle body.

their functions in the CAI is to keep the air moving and maintaining the momentum when the car is idle or during gear shifts. this is when the throttle body is closed (release accelerator during idle or gear shift). so when the accelerator is being pressed again, the engine will suffer less power loss due loss of air momentum in the CAI.

so the AFM will not differ. the fan's CFM is about max 110CFM (120mm 4000rpm 12VDC) while a stock 1.5 carb will pull about 200-300cfm max

the air will not be "too much" because the airbox still have the original "snorkle" etc air inlet (stock). so if there any excessive air pumped in, it will go out from the stock air intake. furthermore, the hose is sealed into the airbox before the air filter.

you can keep the airbox cool and have "enough and compact" air in it especially when car is idle.. no pinging guaranteed.
