What do you think of it? I have a turbo, so the placement is perfect for me. The owner of supras.nl (from which I btw brought my turbo last summer) thinks that the cold air should enter trough the front grille and from underneath, and the hot air should be let out trough the air vent on the above pictures.

Other suggestions for any air vents etc. are welcome.

In theory cold air is at the base of the windshield so it should work well. I have often thought of putting louvers in my hood over the Turbo. How much did you get the scoop for ? Or did you get the whole hood? It looks like a MA70 in the picture.

Im sorry if it sounds like its my hood. Its not. Yes the picture is of a MA71 (owner of www.supras.nl) -- I dont even know where to get that scoop :-(

Again - if you guys have other suggestions for where to install a scoop or vent and what it should look like, I would really much like to hear them.

im a fan of the NACA ducts...

im not really sure how to describe them, so i stole pictures :D
http://www.butlerbuilt.net/page23.html

they work in low pressure areas, and they really flow, but theyre typically for intake.
it seems like your looking for more of a hot air exhaust, so these might not work as well for you.

personally, im getting a metal one moulded/cut into my hood for a ram air intake, hopefully itll look good, and perform well. :)

Those always remind me of the vent for the Turbo 208ZX.

if you are looking to cool your engen bay just take the rubber of the back of the engen bay and add some washers to lift up the hood at the hood mounts . then the cold air that sits at you winsheald will flow in your bay and cool the hoal thing for the cost of 4 washers http://www.jblmk3.com/id50.htm their is a step by step. Dave
Has anyone with a MKII done this Mod? I've always wondered if this will work/help on our cars?

If you do the washer-under-hood modification, you wont want to use your "fresh air" setting on your ventilation system. There is usually a seal at the back of the hood, and the ventilation system draws from there when on "fresh". It all boils down to what is more important to you...

when your parked anyways, when at speed air from the base of the hood will be sucked into the engine bay. This may cause handling issues at high speeds, generally you want to do the opposite for good high speed stability.

If you want a good scoop for cooling purposes, a cfx hood might do the trick. You can rig up some ducting from the main scoop to anywhere in the engine bay you want. Saving 30 pounds off the front end is always nice too...

Yup, I did it when my 2JZ was having overheating issues in warmer weather. It definitely made a difference, especially on the highway! When stopped at the lights you could actually see the heat haze coming up from the base of the windscreen, so it's obviously effective at removing heat.

Yeah Pat... I've seen your Supra and the mk4 intake several times now - it looks sooo great... I would love that on my own too! But, the price on such mk4 intake is probably high :shock:
