You might need to add more pins behind the headlights, dzus fasteners at least.

That sounds right. I paid just under $70 shipped.

2nd picture for an idea. It looks clean and would only cost 10-15 dollars from the hardware store.

shameless plug.

I have an R56 MINI scoop up FS in the classifieds.

I will probably do a vent when my car begins to see more track time.

Someone asked for underhood shots. I forgot to peel off that red tape before riveting it down... I have some TB clearance issues up front so the vent is pretty far forward. It looks like a good spot for airflow with it being right behind the radiator. The hood is stiff enough that I'll probably not reinforce it, but it flexes a bit when raising and lowering. You can shave off some of the honeycomb area if you want another 1/4" of clearance. I might do that if the hose clamp on the TB coupler rubs.

Can you post a more direct under hood shot, like perpendicular to the vent?

Here is a pic of what i had, it help keep the air going into my turbo cold.



Its hard to see but its that piece of aluminum on the hood. Its on the dip of the hood so that it wouldn't stick out into the air stream so much.

Ha, I had one of those Ford vents on my Civic.

http://www.d-series.org/forums/diy-f...r-install.html

I didn't put a whole ton of thought behind my choosing of the location for it, I just ballparked where the low pressure zone on the hood "should" be and stuck it there. Plus with it being FWD, it was also ventilating the hell out of the turbo that was cooking my hood.



Ignore the dryer duct, it was temporary. Car was my DD and had to drive it to work while I finished the actual 4" intake.

I don't know if you consider this DIY since I installed a pre made set of louvers but here is my hood.







The louvers are made by this company.

Hoping the hood will come out about like this. The bump in the vent should intensify the venturi effect, helping to pull the air out of the radiator.
Is there more pictures of his car?
Im really liking his hood louvers. and bumper naca duct intake thing. ive been looking into ways to cut up the bumper but make it look good too.

I already have the mini scoop reversed just want to get some more air in/out on the driver (supercharger) side.

Also want to get more air flowing thru the intercooler which it seems like a hole in the bumper will be the best solution to doing so...

Just as a public service announcement: don't use fasteners like that on a hood. Nothing worse than watching a car burn while people try to find a dzus wrench... nevermind if something happens on track when your tool is in the pits.

They make ones that look like wing nuts that will create a tiny amount of aero drag but at least a corner worker can open the hood. Always need to plan for the worst case scenario.

Where are you guys getting these GT500 vents? I keep seeing references to a $32 or $54 price on other forums, but best price I can find is closer to $64. PN is AR3Z-16C630-AA if that helps anyone.

For refrence, my local Ford stealership parts dept wants $128

Ford quadrupled the price over the last few years. I paid a little under $80 for mine after shipping, which was the best price I could find at the time.

DAMN YOU FORD! DAAAAMN YOUUUUU!!!!

I've been thinking about picking up an extra hood and a '500 vent, mostly for the funsies. My car needs a 3rd panel of a different color before anyone will take it seriously anyway.

This thread and others like it on other Miata sites and the S2000 forums led me to doing some hood vents. I did one large one right behind the radiator and before the engine block and some triangular venting on the driver's side. They will be painted black so they don't look so ghetto. Disregard the black stripes, we did a vent on my buddy's AE86 hood and he painted them on while forgetting my hood is aluminum and will not rust. My whole car is being painted soon so that will be gone. So far we have both noticed a reduction in fumes in our cars and watched the heat pour out of there while we drive. My buddy reports reduced drag, but I think that's all in his head

So rain wise would this be bad to do if I get a lot of rain where I live?
