I don't really agree on Large Snorkel will helps on improving our campro engine performance....
Btw, i done research alot on on Short air ram with open pod air filter of the intake system... which only improve on high rpm and high end torque which is not suitable for our campro engine.... becoz what we need is improve on low end torque... for those who like pickup la.
I am thinking of the put the old waja airbox and fix it with our old cam tak pro engine.I notice that Old waja airbox is a short air ram design and it was also a drop in filter type. Its short air ram design help improve on high air flow going into the throttle body thus minimize heat from the engine and reduced air restriction.
High Air Flow (normal air temperature) + Correct Fuel Mixture = Engine running at Efficiency Condition.
Our current original air ram was long in length and U-turn type design which i dont really think its good design becoz the air velocity has been reduced due to the air that travel slow enough and causing air turbulence to enter the throttle body which is not good.
Seems that Old Waja Air Box is good combination of both worlds but i think there might be a problem. Too much air flow going into throttle body may causing the MAF ( Mass air flow sensor ) to give error sensor readings to the ECU thus delivering bad air fuel mixture on each rpm speed. U all know la, our Gen 2's ECU is quite dumb.
Anyone here who disagree with me and have better suggestion?
I'm the one that have the waja airbox on my gen2, too bad i'm selling my Gen2now.
Below are the few reasons for me to replace gen2 standard airbox.
1) Less suction noise, the airbox is located far from firewall
2) Easier maintenance, no screws only clips and easier to access
3) Shorter airflow path
4) Less heat, as the airflow is far away from engine if compare to standard that run on top of engine and airbox sit on top of manifold.
What I got in return from waja airbox:
1) Better response
2) Easier servicing
3) Less lag when engine is hot
When you said about air volume to MAF sensor, you have to clearly define either it's in WOT (open loop) or Low throttle (close loop). During WOT ECU is getting the reading from MAF while during Low throttle ECU is getting reading from O2. Which means if during WOT there are more air entered to combustion chamber and ECU will allow more fuel as well. But as long the A/F ratio did not exceeded default figure in ECU you still able to enjoy the performance.
