Care to share whats the theory behind this?

Addon

Did more reading.... really depends on the design of the front bumper ler... i think for our cars the effect will only be very marginal

Hi everyone, is there any updates for me here? I just smoked a lancer sportsback 2.4 at kewajipan road just now. He barely can even touch me. Haha.. Drag race from the traffic
Light. That fella is a road rager. Super dangerous driving.

There's a gap between the top of the radiator and till the start of the air guide/cover. This will be the turbulent air zone, which in theory reduces the cooling capacity. Unless of course u can install the cover to minimize the height of the Z height like that shown in your drawing.

Any cooling gains at most is marginal. We're not running our engines super hot, nor are we running in 50C ambient temp. Ive been running mine for some time, i dont see temp spike.
Jack was also running without the cover for a while as well.

Guys from damansara towards kepong... Kantoi towards Batu caves....

use FQ400 bodykit lo.

but, actually i dont think it would be that helpful. our car just NA. i think placebo effect plays a difference here too. but thats just me.

and, when we are travelling at highspeed, the high speed airflow for KNN (>100kmh) is already enough, unless doing dyno, then thats a diffrence when the car is standing still but rev until 5-6k rpm.

but, the engine cover( the one we drilled hole) i think thats is very good to make the car looks more expensive/tidy without it, looks like wira or saga ( 1st gen)

just stating my opinion

He road rage super dangerous, you tapao him means u even faster, u safer driver?

see, i told you guys b4, heat is dissipate to botom....

not above... ....

else this car going to b overheat loh!!!!

The cover serves a few purpose :
1) Looks neat
2) Concentrates cold air from front into the radiator (there is also a fan behind sucking in air)
3) Prevent hot air from engine to flow to the front of radiator when car is stationary (hot air goes up, to the hood cover, eventually finds its way into front radiator which its fan will then suck in the air). So if there is a cover, hot air will not reach the front part).
4) Your engine compartment will not be so dirty, your fan/alternator belts will not get dirty too. A dirty engine is a stressed one. Owner also will stress looking at dirty engine as compared to clean one. Go tt show ppl also paiseh if dirty.

i put it back already....
but I dont really buy your theory....
