stick it to the bottom of the vent. It works.

:rolleyes: You're the expert.


OP: It's wouldn't be a bad thing to try if you're bored, but I would take the result with a grain of salt. Unless the string (shouldn't be more than a inch or two long) sucks into the vent without a doubt, I wouldn't make any conclusions one way or the other.

The positioning of the vent looks good, and it will definately help extract heat and high pressure from your engine bay (as you move, airflow into the radiator and engine bay creates pressure under your hood, this vent will help that as well). And the vent will help radiate heat out from under your engine bay when you're stopped.

More Pics!!!

I'm sorry I can't let this die. Many people complained about the AK hood because it sucked air in, rather than let air out through the vents over the engine...this vent is in the same place, just like when people raise the back of the hood because they think it lowers temp by pulling air out, which it doesn't.

If he could show that air was going out at speed, then I'd do the same to my car. Until then, I'll plan on the carbontrix vent

Which is why a magnehelic gauge is useful for thoes of us without wind tunnels.




I like this newb.

Send me a pic of the AK hood and Carbontrix vent.

Raising the back of the hood opens a gap where their is high pressure (at the base of the hood) -which is why many muscle cars (and the Grand Am Rolex SpeedSource RX8) have their air intake facing backwards at the base of the windshield. I already stated this.

Most likely, air will not go in at speed due to the shape of the louver, position, high pressure in the engine bay etc...

Their is a low pressure zone at the sides of the base of the windshield. We raised the hood but blocked of the center high-pressure area while having an opening on the sides of the base of the windshield to vent the radiator exhaust/high pressure under the hood etc... in a different Grand Am RX8. It worked but had other adverse affects -as everything is related.

Aerodynamics is a lot more technical and in depth than you are making it out to be as everything affects eachother and their are many misconceptions and misunderstood physics behind many people's understanding of aerodynamics.

You last post was the first acceptable and nice post to reply to and debate, I hope you can keep up that maturity.

Or you can hook up some pressure gauges to a Motec and datalog your runs and see the pressure effects at varying speeds ;)

Incorrect, they complained because some questioned the funcionallity and asked for test data. AK got upset took their ball and left to play with CR. There was no data on either side of the argument.

The AK hood originally had 3 gaping sets of vents.


If you can ship me a functioning motec for $25 I'd use that instead. :giggle:

ah yes. Then I stand corrected and its still up for debate...unfortunately. It would be cool to get a straight answer on this before I start cutting. I thought Emelio did something with it.


I could go for some motec in my life life too.

Maybe i'm just spoiled...;)

Sure, if you pay for shipping, you can borrow my M800. You'll need your own pressure sending unit though...

of course it is. But if the string is going out the vent, there is a pretty good chance that you're winning the heat battle.

heh, you're right, but it just reads weird like some of the ethug posts.

put some of these near your turbo in a can or something and go for a drive. voila.

I very well may take you up on that offer. Not today. But when I've got some other things sorted out, it could be very useful.

That color is freaking nice, minus the chips. I like how they follow the hump in the hood. At idle the heat pours out those vents, I have the AK hood and it does the same,,,At speed though I don't know i'm usually to busy driving and listening to it spool rather than try to give a shit about 20 or 30 degrees.

Is it really that important on a street car, Or am I missing something?

haha, damn, this thread blew up =P I'm uploading pics currently ...

The color is from Toyota, but I don't know what the code is. It's a dark gray with blue, red, and gold flake. I want to repaint the front bumper and clear bra it ... but that'll have to wait for a couple months while I build up my bank account.

The car is eventually going to be my dedicated track car, so the louver is on there so I can vent off heat between runs.

BenR, I'll have to take you up on your offer. I'm curious to see what happens to the air at speed.

Nice, where do you live? In Alb? I noticed you and BenR are friends.

Fireindc: I've been chatting with you on RSW about the MegaSquirt tuning that you're planning on doing ^_^

looks pretty good, feel bad for your bumper though, also I hate these rims...
