My prob. is all the under hood heat. The high temps in the little cramped engine bay is heating up everything.

I seen post, read post and done a search on "fender vents" and none talked about it as a functional mod. They all was about looks.

How would you go about ducting the vents into the engine bay so it can pick up the hot air and let the air pressure from the vents and aero flow along body sides draw the heat out?

The whole inner fender is the strut tower and I would'nt think it would be a good idea to cut a 3-4'' hole in the side of them for the ducting.

IMO just putting the vents in the fenders is gonna go nothing more than change the looks of the car, because the only "holes" in these third gen inner fenders is as the front like where the batt. goes and little tiny holes at the back where the computer's wiring comes through at.


Anybody with any ideas, tips, info, etc please chim in

Thanks

TTT

Anybody? Any ideas on how to get the hot under hood air out of engine bay, with fender vents, hood vents, anything????

i noticed on trans am/gta hoods, that there are vents towards the back of the hood. they're not functional, but perhaps they could be cut underneath to make them functional......... just an idea

I installed mine......but I had said the heck with making them functional. It's just about impossible without having to hack them to pieces. The frame support is in the way.....and the louver will barely even fit. On the old 2nd gen style....they didn't have this problem...and they worked really well. Flynlow92RS put screen behind his.....which might work....but not nearly as well because of the frame support being in the way.....

Thanks guys. I been looking all over and under my car and I cant see no way of makeing the fender vents really functional.

I been thinking about maybe just adding hood vents to the hood. Something like the chrome 1st gen camaro ss vents. That would take care of the heat under the hood, then making a ram/cold air setup useing a hood scoop and sealed air pan from the carb to scoop. Place the hood scoop inbetween the chrome hood vents, run a trans cooler, and a fuel cooler and not worry about heat anymore.

Thanks again
John

BTW... how yall think the chrome 1st gen ss vents would look on a third gen hood?

Get an SS Hood

The fender vents actually do cool the engine down, not enough to warrant putting them on for cooling purposes, but they do cool it down....

They allow the warm air that gets caught at the back of the engine place a way to escape..........

To save money i'm gonna use the OEM steel hood. The weight diff aint that much and for a daily driver it dont justify the money.

Plus I want my own looks so i'm gonna get a 67 vette 427 stinger hood scoop, and mold it into the steel hood. That way I can place it just how I want it.

My intake set up is a performer intake, 1'' spacer, 10 x 3.75'' K&N filter. That will stick well up into the scoop.

Make a sheet metal pan thats about 14'' on all 4 sides, with a hole cut in the center to fit on top of the carb, then the air cleaner ontop of that. Measure from the shet metal pan to the bottom of the hood, then get some foam that .5'' thicker than that and hot glue to the sheet metal. That away it seals to the hood around the hole cut for the scoop.

I'll use a small trans cooler (fin and tube type) in the air flow to the rad. Hook that up to the fuel line (off pump to ccoler, off cooler to carb) to make sure the fuel stays nice and cool.

A B&M 24,000 GVW super cooler plus the auto rad. for my trans coolers.

So all that stays cool but the tight crampped engine bays in these things holds heat like crazy. With all that air under there its just gonna re heat everything some and thats what i'm wanting to stop

I just wanted to say that these really work on a 2nd gen, but the fender is set up completely different to make it functional. If you look under the hood of a 2nd gen, there is a square sheet metal piece that runs over the inner fender to the vents. This flows air from the radiator to the vents. My cat actually crawled into this one time and you could see it through the vent. Had a lot of fun getting the thing out of there.

I think that you may be able to look at the setup on a 2nd gen and get some ideas. I plan on drilling a grid pattern into my TA hood vents to gain more airflow later on.

Do the side vents work on the 3rd gen TAs?

from what i see, they don't. all the vents on the hood and fenders looked just for decoration.

Yeah I own a 78 trans am ws6. The gen 2's the vents really do work, but on these third gens the strut towers are in the way and blocks off the path for air to flow from engine bay to fender vent. In the gen 2 f-bodys The inner fender aint blocked by nothing.
