So Chaser posted over on the other forum the NA extraction hoods they finally received. But part of the pictures and description got me thinking:

My understanding has always been that an opening designed like that would be induction rather than extraction. I'd like to know if that's incorrect. If I am correct though, what will this hood do to the airflow through the engine bay considering the extraction vents?

 

My favorite products are the one where the designers proudly display their lack of understanding in the product description. That hood will increase engine bay pressure by opening up a high-pressure vent at the back, and the vent at the front will become less effective as a result.

 

I'm with Savington. It is just a fiberglass/CF layover showcar piece. Not to mention if you followed their Hardtop groupbuy on CR.net.... quality and such is crap.

They are a knockoff crappy import bodykit company. Not much more.

 

That's what I was thinking, with that vent at the rear it kinda cancels the extractors out. I can see air getting pulled out thru the extractors and then going right back in thru the vent at the rear.

Agree with all of the above. If anything, those vents in the back should be covered. Im sure itll cool the engine bay off a bit with those vents in the back closed.

 

It will work really well at idle.

Chaser Aero: "The name sounds cool, but we really don't know anything about it."

 

Looks like they got the corner ducts from autozone

 

If you need an extractor hood there's only three options I would consider.

A. Buy a hood from rharris.
B. Find a used FM hood.
C. Put and extractor scoop in your stock hood. Use either a Mini Cooper hood scoop flipped around, or use the Carbon Trix scoop.

You forgot D.
Hack the oem hood up

 

What's the consensus on the Autoconexion vented hood? Mine has been sitting here since early '08, and I still haven't used.

haha yeah, but that kinda falls inline with C.

I had both versions and they worked awesome. Phil got to see them

 

Otoh- box in that vented cowl area (isolated from the engine bay) and you've got a cold air intake source.

 

I think it's ugly... ?

 

If your next post is an ad, get ready to wave goodbye.
