EurosportZ34 Posted November 5, 2004 Report Share Posted November 5, 2004 What would the hood vent do? OMG are you serious dude? they extract heat from the engine bay. they are fully functional when they baffels "drip trays" are removed for summer driving. they are big pimpin' here's some shots of my Z34 this past summer...

Only thing is, at high speed, your vent won't help you as mush as a Warber style hood. Those tend to help keep the front planted to the road. Still, I have always likes the Z34 kind....

dsgrntld187 Posted November 6, 2004 Report Share Posted November 6, 2004 It keeps the front planted better? How does it do that? Quote Link to comment Share on other sites More sharing options...
WhiteOut Posted November 6, 2004 Report Share Posted November 6, 2004 It won't help to keep the front planted better at all. It will effectively create a low pressure center, or vacuum condition, in the front of the hood. And technically that should reduce downforce not increase it as suggested, in the real world however at less than subsonic speeds it probably has about zero effect.

HokemBokem Posted November 6, 2004 Report Share Posted November 6, 2004 I was wondering why my car would suck in air behind the left headlight? It seems like there would be no airflow back there? Quote Link to comment Share on other sites More sharing options...

If you read the Fiero forum posting you should have picked up on this, but by custting the hood ,& bending down a flap so that even a little airflow will come through the grill and up through the vent. What that means is that at high speed more air being forced through that vent turns into downforce. This is even measurable with the right equipment. It works, plain and simple, why do you think most high end sport cars have hood vents. BTW , no flame intended here for anyone, sometimes these thing can be hard to explain face to face , let alone over the internet. Here is a pic on a Fiero... can someone photoshop on on a Cutty.

I realize that at high speeds it has some effect, but as previously noted it creates a low pressure center or a vacuum effect. And I believe that you'll find the main reason ALMS cars and other road racers have these types of hoods is due to that vacuum effect being used to suck air in for cooling purposes.
