hah - I had you figured for a paste eater

 

Lead paint.

 

nope, boogers.

 

The secrets out

 

chinese evo extraction hood vent
thoughts? takers? it's cheap, it's ricey. Wonder if it would interfere with the hood "bubble" at the front.

 

You first

 

I would (I've already got holes in my hood) but I bet it'll hit my cam gears where it dips down for the extractor since my engine sits almost 2" further forward and 1-1/2" higher than the B. Right now the t-belt is about 3/8" from the hood skin.

I'm actually considering 280zx turbo vents (one has the naca scoop, the other doesn't) IF the angle on them will fit the cowl hood line on the Miata. White car is a vw carbrio- and the vent angle doesn't jive with that squared up cowl line. The Chrysler Lebaron GTS vent would work to IMO - but it's big at 10x14. Has an inch taper on it that will work. I laid a template on the hood - but it IS big.

 

So the opening is 2" deep, and the vent sticks up 1.5" and hangs down 1.5"? Unless the fiberglass in .5" thick, they need to buy a new ruler.

 

abuddy put a 280zx vent above the turbo on his 240sx... it worked well and looked good.

 

with or w/o the naca? I wonder exactly what the naca duct at the front is going to do. Was it engineered by Nissan? I'd hope so. Where's the experts?!

 

I doubt that naca duct would do anything.

 

I have these lebaron vents on the jeep hood, they work well

 

NACA ducts suck air in. putting a vent right behind it is ... uhmm... curious.

 

If the NACA portion of the vent was positioned right in front of the compressor and the vent portion of it directly over the turbine, maybe it would force a cooling path across the turbocharger.

 

Yeah, if you think of an engine bay like a computer case, where cool air flowing through it efficiently is more beneficial than a shitload of fans simply sucking air in, a NACA duct combined with a scientifically designed/placed extractor would work really well.

 

BYW cutting holes in the hood with a jigsaw is a BLAST

 

So I guess the question is- were the Nissan engineers thinking scientifically when they stuck that naca duct there, or was it done for visual impact?

I'm from the "cutting wheel on grinder camp".

 

I was thinking about the idea of using a sheetmagnet to cover up the holes for whatever reasons you might decide upon.
How is the magnet going to work, aren't the hoods aluminum?

 

Nice Rob. Way to ruin a perfectly good hood.

 

That hood spent 2 years under a walnut tree. So I suppose someone who owned a dent-popper shop might consider it perfectly good. Ain't no way I'm fixing it. That was pre-subframe-shim, when I was going to cover it up with an early 80s Mustang GT hood scoop. When I saw that it was barely touching, I went with the shims and some trimming of the hood ribs to get it under the hood.
