Decrease intake air temperature - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

AceHeader-MT · 11-01-2013, 03:43 AM

I remove the plastic panel above firewall (below windshield), when I race at the track. Intake air temperature got huge drop.

I made a fresh air-hose for air-condition, in order to avoid suck smell air from engine compartment.

Fresh air-hose goes to front.

I plan on doing this same thing. I was also hoping it would help with hood lift. Have you noticed that?

I was too busy at the track, so I did not pay attention!

Yes, I will be in trouble if it rains.
So, I am making a custom penal now, I will up date when I get it back from powder coating shop.

Makes sense, btw I've seen guys drill out side vents which does same thing really.

I add some pictures of modified plastic panel, now I can drive it in the rain.. Intake air temperature got huge drop.

Very nice, indeed!
Where did you get the two, square mesh plastic panels?

I assume your talking about cabin air temp not engine air intake temps?

Hello, I mean engine air intake temperature.
During the 25 mins practice driving in PIC taiwan, intake temperature drop from 45C to 35C.

Very Interesting. I can only assume this mod reduced the under hood pressure enough to change the airflow characteristics in the nose area... do you still have the stock intake snorkel with the TRD intake?

I need to do some pressure measurements asap i guess.
