I like.

Correct traditionally we see the vents going the other way....I did the same thing seen reposted in post #64 just that I didn't completely cut the vent out. Rather I bent the vent flap level to the ground. It's not to catch air as an intake but rather keep air moving throughout the engine bay. The nismo RS concept vents are placed so perfectly on the nismo racecar. If you crouch down and look at them you'll see that air is hitting the intake pipe/TB/manifold full on...

Is the back (against the windshield) open also?

Love the look.

If you want a cheap way to test under hood temps go to Walmart and buy a cheap battery powered oven/meat temperature gauge. Get one that is meant to be placed outside of the oven with a long hi temp cord attached to the meat thermometer. Or even better, a wireless unit.

Depending on the length of the cord, you may need to zip tie the gauge to your windshield wipers so you can see it through the wind shield.

I used this method to see what type of under hood temps I was getting in the master cylinder compartment (after multiple slave/clutch master cylinder failures at the track).

What I found out is that temps spike rapidly any time the car is not moving. And that it is vital to open your hood AND plastic brake and clutch master cylinder compartment cover immediately after getting off track.

They also make stickers with dots that turn color to show what temps you hit. I can't remember where I found them, but they're out there.

lessons learned from this is (1) I should have moved it to the edge of the hump...I slighty cut into it. Aesthetically it would of look ten times better. (2) bending the flaps would be easier if I cuted/trimmed guide on the backside of the hood with a dremel. Would of helped bend the flap easier than using force. Other than that having the proper tools made it really easy to do this.

Next is similair style on the fenders like the GTR racecars..because I'm a ricer

I got a OBDII read out and I've noticed that temp drops quicker when moving than before...

Syno do you have a picture of how the underside of yours worked out? Did you pick that spot for alignment with some of the stock bracing on the underside?

Yes I did. I wanted to cut though only 1 layer and not through the bracing. I ended up cutting a little though because I needed an inch of back cut to have room to glue the mesh to the hood. The front bracing also bends down and away from the hood and that natural bend line was easy to follow.

Yes it looks like crap! I used dikes and I cut and pulled and tore the metal off because I didn't want to make more of a mess with metal shavings from grinding and I don't own cutting shears. But I don't care, no one sees under there.

As seen that's also as far forward as you can go anyways (right where the bracing bends down). Any further and you're over the radiator shroud that has no point to vent.

What did you use for the edging? Looks very clean

Then used a sanding stone to smooth the edges and debur. On the inside I used dikes to cut the reenforcement back an inch so I get room to glue the mesh to.

I also laid down a strip of metal as a guide for the wheel so my lines where straight. You can see it in the pic in post 11.

First page.

I think he ment the rubber edging

Ah, door edge trim from autozone.

Who wants to order something like this and see how it looks?

$250... could be worth a shot.

I like how this looks...might cut the hole then get the hood repainted(stone chips, thanks PA) that way I do not have to worry about the edges rusting...unless I missed it in the thread was there any significant heat reduction other that you know heat is coming out of it? like oil temps or water temps?
