Why not make it so the vents are over the hpf logo on the intake manifold? Then everyone knows its hpf car.

Am I the only one who thinks these look like a goofy hood you'd get in a video game like need for speed? I really dislike the middle duct/scoop w/e it is. I guess I just want a vorsteiner replica in all honesty.

Eww... just my opinion, but those hood vents are gaudy.

Really, you guys should get an actual engineer at your company, or at least talk to one in exchange for a few beers. Then if you were making gaudy hood vents, you could at least design them so that they suck air out of the engine bay, and don't push air back in. The E36 and E46 M3 GTRs had their hood vents in their locations for a reason.

Thats (unless I'm mistaken) a 190E DTM wing.... not an aftermarket wing. So while yes.. its a big wing.. its also true to form for a early 90's dtm race car.

Correct, and OE Mercedes-Benz part.

Period anecdotes tell of a BMW executive who was quoted as saying "if that rear wing works, we'll have to redesign our wind tunnel.". The anecdote claims that BMW did.

I am not exactly a fan of vents either, but the benefits of getting all that extra air cooling the motor, coils etc can not be discounted.
If there be vents, then why not something a little more aggressive than the past?
I may change my mind totally once I see the drawing rendered better.
I would like the artist to do a better drawing of an entire CAR with some of these hoods in place. Some of the hood is not rendered that well as far as being 3 dimensional. its hard to tell what dips and what is supposed to be raised.

Chris, can we take the renderings a bit further so we can get a better notion? Thanks.

I really like the detail to construction, rigidity, fit and finish. Nicely done.
Now, who wants to buy my painted Imola hood with 3M clear vinyl bra?

Poor mkodama...right to the point from an engineering perspective.

Unfortunately he's right.

The area towards the very front of the hood is a low pressure area, then it transitions towards high pressure at the back. The reason why the HVAC inlet is placed where it is, is that it's a high pressure area that literally self feeds as vehicle velocity increases.

If I was going to put a vent at the center, or towards the rear of a hood, I would build a lip before the exit point to help create a low pressure area.

Oh...and to keep a hood down, so it doesn't flap around...you want to seal the back of it close to the windshield. I've seen many race cars (that have gone to great lengths to save ounces from the chassis) have a full OEM rubber strip at the base of the windshield to help keep the hood down at speed.

But...what do I know...I don't have a Doctorate in Engineering. (Heavy jab at mkodama)

I like the first one. And it appears they all have some sort of lip just forward of the center vent.

I don't know about all this, but, yes, Chris...first and foremost I need to think that the hood is FUNCTIONAL. That is more important than anything else. It should be creating a flow through where hot air is being removed.

I am 100% for function before form in this case.

Should have bought your first because of the E30! Get to the AMG forum!

Choices choices choices, a couple remind me of my Asuka hood. Interested to see where this goes.
