Hoods.

[D's GS-T]

Are there any good C.F hoods out there that properly vent ait out from under the hood. I figured i could save some weight, and get rid of some heat all at once by picking one up

I'm kinda in the same boat... Searching for a vented CF hood that is functional yet clean looking.

After looking through many pics, the VIS Racing Extreme GT CF hood seems like it might fit the bill. Here's a couple examples:

Do you think those small vents would be as effective as an OEM CF hood with a strategically placed Carbontrix vent or two?

haha but theres other ones ive seen that have a bigger vent in the middle that one is sick and is the perfect one for you

I haven't seen either in person, but judging by photos I suspect the two vents in that VIS hood would equal one carbontrix vent. Perhaps someone with fist-hand experience could chime in. *shrug*

Here are some pictures of an OEM CF hood with Carbontrix 18x10 vent. I don't have any measurements for you off hand, but it looks like it'd be close or a bit bigger than the two vents in the GT hood.

I worry that although that hood above looks better than a carbontrix, it is not nearly as effective. First of all it does not have a lip to help produce a low pressure zone above the vent increasing the effectiveness of the vent. Second the location, it looks to be above the valve cover, instead of right behind the radiator. Third, again location, the farther the vent is up, the more itll first be away from the airflow that your trying to vent out the radiator, and second itll be closer to turbulent air near the base of the windshield, again, reducing the effectiveness of the vent.

I had great success with the carbontrix vent and could see the effectiveness when I sprayed the front with a powerwasher, you could see the vent actually PULLING air out and over the hood and over the roof (like a windtunnel effect). It also effectively reduced my coolant temps on track. Also ducting up your front end greatly increases the effect due to higher pressure moving to lower pressure (vent).

I have the carbontrix vents, I live in phoenix, 115 summers. These things works wonders!

/\ Very nice. Do you have info on the install?

so clean, yet so functional

I'm rocking this hood from Seibon.
It is a very high quality piece.
The vents are large enough for a cat to climb into your engine bay if the mesh wasn't in place.

I know this post is pretty old, but does anyone know if this carbontrix hood is still available??

I just got one from Carbontrix but they changed vendors and it took 6 months to receive.

I dont have any data as to Underhoods temps. But theres an old school mod of using a few washers where the hood mounts to the chassis.

Terrible idea. Cowl venting doesn't work on our cars.

 

[Bud92gsx]

It probably doesnt work. I have no log data to show it doesnt work, I wish I did.
