those of you that have them, where did u mount them on your fc? got mine for xmas for the custom hood i made and i want to get an idea of where the best place to mount them on the fc is. pics of the spot would be beautiful *hint hint*

The factory instructions use an FC RX-7 as an example for placement:

I installed them on my old tiburon. Here's how I installed them.

Find hole in radiator core support where pin and catch will not end up on a structural part of the hood. Drill hole larger if needed.
Cut pin if too long. Clean end thread up.
Put black rtv silicone on top of pin and close hood.
Use punch where rtv is (if metal) and drill a pilot hole.
Use supplied template taped to hood and cut with a reverse cutting drill bit (forgot actual name. Home depot has them). Drill holes with a normal drill bit.
Use rivets to instead of supplied bolts if the hood is "double walled".

Tip: you can rotate the pin and have the catch angled of needed

I remembered. The bit is called a rotozip.

Horrible way to do it. Why not get 2 correct size holesaw bits to make the ends and then all you need to do is connect the tangents. Much easier, much more accurate, much less of a chance of ******* it up.

The real reason I'm here is to ask for pics of this custom hood you built.

ya..+1 post pics of the hood...and TT has the "ticket" for doing them latches.,they are a little more involved than just putting a couple holes in the hood.
...
I just installed hood pins on my FG hood and I measured the Distance over and over( I got **** about it.)..I used the top rad support.
I put a 1/8 bit through the hood and it in turn marked my spots to put the pins.
I had the hood open when I did this to make sure that the drill bit would hit the support in the area where I wanted it to.

ok ok i get the hint lol heres the pics







it no longer gray its now the same shade of primer as the rest of the car, and after taking these pics and looking at it a few times i decided i had to do this

TitaniumTT

Why a duct facing that way? That's more of a lower pressure zone.

Evil Aviator

Yes, but it will still get ram air and it looks neat that way.

TitaniumTT

Yes, but ram air for what? Is this just to circulate air through the bay? Or is there an airbox in that location?

You haven't seen the hood I built, have you Evil?

yea its just to circulate air through and cool things down

The only hood of yours that I have seen was the one on the car you drove to DGRR 09.

That will increase drag and possibly cause the front end to get light at high speed, and there will be no gains. If you don't have an intake or heat exchanger for that duct to feed, then you are better off blocking it off like you see on production cars that have fake hood scoops or fake brake ducts.

TitaniumTT

Ah yes, the bone stock hood. I went a little crazy with a jigsaw, welder, bender and a dream


Do you remember how my setup was? I decided to take your advice above and duct it specifically for the heat exchanger












Didn't help all that much while at speed becuase I ducted it as tight as possibly BUT it does seem to help with heatsoak. Thoughts? Critisim

Evil Aviator

Oh yeah, that will work. Maybe the flared lip is creating turbulence and hindering the flow a bit at high speed? Hmm, I always wondered why those Japanese tuners do that, as you never see flared lips on aircraft vents. Also, the cross-sectional area is quite large and there is only a couple inches of duct wall. I wish I had the resources to put one of those hoods in a wind tunnel to see what is happening.

Geez, it must have taken you forever to make that vent. It does look good.

Wow Evil.... checked out your pics. Incredible job on your hood. Very professional and beautiful end result!!

Evil Aviator

That's TitaniumTT's custom hood. All of his stuff looks good.

My hoods are:
- Stock TII hood with the guts ripped out for engine clearance.
- Stock vert hood with a slight crease from when the previous owner's wife ran into the back of a truck.

Wow seriously impressive work by TitaniumTT.

Here's where we mounted the pins.





We have a ViS CF Tii hood so that would be different but we marked it like previously mentioned and then drilled a hole so the pin came thru and then centered the template on the pin.

Good luck
