Bonnet Duct

[SargeRX8]

There was a chap here selling some parts, in the picture he had an R33 bonnet which had a vent/duct fitted to the standard bonnet just above the filter location. It was NOT a flush mounted vent, it sat on the bonnet rather than moulded in. This is what I want. Does anyone know where I can get one? Most I find are mounted from under or flush mounted, but these ones that sit slightly above would be an easy DIY(no putty work, cut, seal, paint and fit).

Something like this but not CF http://www.justjap.c...518&cat=&page=1

Or if I can get one in CF, cheaper, that would be mint.

Is this price fair? Can anything like this be found locally?

How do you order it? They do a carbon fiber piece too, but there is no price....

Hi

then click on "Contact Details"

I used the 3" wide one, but have a chat with Ken to see which one suits you.

My car is currently in the shop fixing rear-end damage - they're going to be re-spraying the entire car. I can't decide if I should take this as a sign to fit one of these ducts whilst the opportunity is there. I've googled around images for the 'real' NACA ducts on v-specs, and they seem to mount them from the top rather than the bottom (and then almost moulded into the carbon bonnet underneath from what I've seen).

I can't decide if it would look better or worse to mount from the top of the bottom - have the edge around it on top or more like Terry's old car where it was done from underneath. I suspect there would be better airflow from the top method, but I'm worried it wouldnt sit flush enough or look 'right'.

Gah!

Reference images:

The other thought I had was whether I should just replace the bonnet altogether with a GTR one (NACA duct in it..?), replace hinges, latch, upright, then try and find a bonnet mole to fit ..

.. decisions, decisions ..

That kind of looks nice but I also kind of don't like it. This is what I want and I want it in CF. My car is white, and anything CF on white looks minty.

I really want it where it is in the pic I attached but I can see use for both locations, at the rear to cool the turbo, at the front to feed my air box. Ahhhh decisions decisions!

Thread dig, Has anyone else modified their bonnet to fit a vent?

I've had to cut some of my bonnet re inforcement out to fit my turbo so I was thinking I'll put something really subtle in.

That way I can get rid of some excess heat/ have cool air onto the compressor housing

Old Pic Joey.

I do like that vent terry, though I don't think it will give me the turbo to under bonnet clearance,

I need something that slight pertrudes as appose to inserts

heres mine off ebay

Looks pretty sweet!!

[GTR_JOEY]

How much to buy and install?

[Charles89]

I've got a brand new carbon fibre NACA for sale if anyone is interested?

I know this is a Cosmetic threat, but the mention of cooling down the turbo triggered the memory of a tech article I read once on the benefits of reducing the amount of heat lost by using wraps and blankets and such.

Interesting read: (ignore the product placement, the theory is transferable)

Essentially turbine heat (of the exhaust gas) equals more power, and letting that escape ain't so good.

Cosmetically, I don't mind the look of these in the front near the airbox, but to me looks kinda weird up the back near the turbo.

Thanks Andrew.. Makes complete sense as hot air expanding is what drives the turbo.

I wanna know if it would be advantageous to have the cool air running over the compressor housing.. Surely it would
