Front Bumper + Hood effective cooling options

dimmaz · 05-13-2020, 08:21 AM

Hey guys, so I’m in the process of trying to decide on a new front bumper and hood.

I’ve pretty much decided on the Fujimura front bumper and was considering going with the matching hood to go with but what’s your thoughts on either the Varis or TrackSpec Vents?

The Z is a daily driver and track day car so cooling is the main aim but also having to consider water from rain or hand washings. I know that the Fujimura has some kind of ducting but not sure if Varis does? TrackSpec definitely doesn’t.

Does the Fujimura hood have as effective cooling compared to Varis or TrackSpec Vents? They do have a different layout compared to Fujimura.

Thanks cv129 (and cooltoy) for your reply, much appreciated. I had not read that post and it was very informative and interesting.

My understanding from all that I have read is that the placement of hood vents is important for proper cooling airflow.

TrackSpec and Varis seem to be similar in design with 3 vents placed in key locations to allow hot air to escape.

On the other hand Fujimura has 2 vents on each side in the middle and a vent at the rear closer to the windshield. Does this vent further back hinder air escaping properly from the forward vents when at speed?

Hotrodz should be able to chime in for you. He used to run the Fujimura hood and switched over to an OEM hood with the trackspec vents a couple years ago

Personally I am using the Stillen bumper and Track spec vents. I chose Stillen because of the simplicity of adding brake ducts even though the fitment isnt great. The Track Spec because of price and known functionality, but it is scary to make that first cut into the hood.

Hood wise you want something with an opening right behind the radiator and would have a bump in-front or have the vent depressed like the Seibon VSII or BD ones. The further back a vent is the less effective it is.

Red and Orange are the best places for air to enter the car, hence why the cabin air comes in right next to the windshield, and blue and green are the best places for air to exit the car, hence why the Porsche 918 has top rear exhausts, and they look amazing too.
