since you guys keep buggin me...

If that's not strictly a track car.....Lame ........ and if it is a track car it would have been of more benefit towards the rear of the hood.

Will you please enlighten us as to the positive and negatives of these two placements?

I would love to hear the logic behind this statement.

WTF??? like any e30 with a proper cooling system needs a big hole in the hood!
looks like crap imo. but the rest of the car looks good.
had to believe it was a euro old skool car though.

DOHC engine in a small space in a hot climate. Even a good cooling system is going to struggle there. Tack on track usage and you're going to need any help you can get.

Looks good to me. Where'd the vent come from?

I agree with Charlie. After driving for a few days, the temperature needle shows a cooler running car. Also, considering during summer time ambient track temperatures can reach over 140degF (Willow & Buttonwillow in summer), this is definately a benefit.

Plus if you get tired of it e30 hoods are cheap.

Youre so right. We all mod our cars strictly because we take them to the track and should only mod them for the purpose they serve. If it doesnt see a track, then you shouldnt be modding it.

I may be over analyzing this but hear me out.

Heat produced by an engine has a tendency to collect in the rear of the engine compartment. Thus the reason many high hp muscle cars had rearward facing cowls. That is where you want some sort of heat extraction.

I wonder if you've actually made an air intake? Problem with that is where's that extra air going to be expelled. Turbulence is the word that keeps reeling in my head when I see that "vent".

Edit: I see now that the ribs on the vent are directional. Maybe it won't draw air in, but I still think; front of car (or engine compartment in this case) = intake/ rear = exhaust.

Does heat get trapped because the increased air pressure in the front of the compartment keeps it there?

I think this will alleviate that by decreasing the pressure inside the bay and allowing better flow of the heat up and out. I figure the two biggest heat sources in the bay are the radiator and the exhaust manifold. This vent looks like it will remove much of the radiator heat up and out.

But like the OP said, it's primary purpose is to negate lift on the front of the car. 8-)

Its a vent, people. I doubt the owner was getting into the physics of heat extraction when thought of. At worst it doesnt hurt. Its a unique touch Trent wanted to add to his car, cant it just be that without people breakin down motives and/or functionality? I dunno, I respect the info and all, cuz its always useful, I just dont know if this needs to be taken so seriously. :)
