Personally I would move that center vent closer to the radiator for more effective cooling $.02

It's should be 15" from the front of the hood.

Yep like I said, closer to the radiator. Having just measured my hood, that pic puts the lowest edge at about 27 1/2" from the front of the hood measured from the hood center line ;)

Yeah, this is not how they will be installed, the post was just for fun ;) I may even use a thermographic camera if I found one with my track mates before installing to maximize their effect.

No need for the camera, sounds like the instructions have done the research for you. The radiator is going to give off the most heat & you want to vent in a low pressure area of the hood. The more you vent the radiator, the more engine heat it will absorb, keeping things cool ;)

Yeah, you can see the heatwaves just at idle!

Ok, dumb question as I haven't installed mine yet. What do you you do when you wash your car? My car is new and the engine bay is pristine, I really don't want a bunch of water down in there.

If the engine is cool. You can put a sheet of plastic over the engine.

Yep, thought about that but sometimes I'm lazy and I take my car in to get it washed and waxed.

I was thinking of using a beach or using vinyl carpet wrap to cover the vents. The wrap is cheap and won't hurt the paint for what little will go on it.

You also put cling wrap over the vents. Just don't hit it with too much water.

There a number of creative ways to deal with washing the car. So far it has not been issue for me. Just go off road once on the track and that will be worst than water to clean up. Ask me how I know, LOL!

Video please. :rofl2:

Try rubbing off rubber marks from tire bits. :eek:

You know I have some video, I just need to edit and upload it...I one other from this past weekend. I am sharing way to much...but I am a fan of Ricky Bobbie! First or crash LMAO!!!:stirthepot:

That is what I will be spending this weekend doing. Getting all those rubber marks off the car. Part of me likes the look...because race car!!!

:rofl2:

Where did you get that splitter and side blades??

They did their work and I will go with their instruction, but if I can use one for free, it will not be a bad idea, specially that I am installing Mishimito Rad now and it may differ a little.

I got them from AeroFlow Dynamics: https://www.aeroflowdynamics.com

I went on the website and did not see anything for the 09-14 Nismo. I called the guy and he said he would need someone with a 09-14 nismo to come by the shop so he can make a template..... WTF...

That is really odd. It does look like they change their website from when I ordered mine. When I placed my ordered for the side blades it was for the Nismo 09-14 version 2.

The ones on the site look just like the ones I have installed. I don't know if they changed the dimension or not. I just went back and check my order in my email and I don't know if the image and detail comes directly from their website but list them as the Version III and the same picture from their web site. The pictures on the web site now are different than when I ordered my blades in Sept.

I just took a hard look at the pictures on the site and they are of a Nismo. The side skirts are a dead give away.

I got blasted by some rocks when a guy went off track and flipped them out to me, ended up with a bunch of chips and a broken windshield. I might need to pick this up before I repaint my hood...

Damn dude that sucks, I use trackarmour!! It’s the best stuff not pricy and protects your paint.. here’s a link

TrackSpec Phase I
 

Disclaimer: This isnt a how-to, just providing some info that might help others.

Tools:

Harbor Freight 4" corded angle grinder [HF #60373]
SAS adjustable Face Shield [HF #46526]
Safety Glasses
Dust mask
Diablo 4"x .040" (1mm) Metal Cut Off Wheel [Home Depot #247559]
Blue painters tape
Moving blankets [HF]
Plastic
Exacto knife
2 testosterone filled sacs

Tool Notes:

Cut Off Wheel - I purchased 2 but you'll only need 1.

Safety - I used a face shield and safety glasses. I used a dust mask and some ear plugs too. Make sure you re-adjust the angle grinder shield to best protect you.

Exacto knife - Used to cut and peel off the template guide lines. I spent a good amount of time doing this.

Prep Notes:

Blankets/Plastic - You'll want to cover the entire engine bay and from the top the windshield forward. The aluminum dust gets everywhere.

Masking - I taped off a huge swath of each side for the side vents. Only on the top, I did not mask the underside of the hood.

Cutting Notes:

General - Let the tool do the work. Dont push to vigoursly trying to cut through faster. For each straight edge I made some back and forth motions, slowly and carefully, across the entire length to start a groove/cut line. I then plunged about 1/4 of the way from a corner, backed into the corner then proceeded the rest of the length.

Corners - The corners are a bit tough. Just keep an eye on your cut line and dont overshoot. Most of the corners turned out ok but 2 of them I had to take a longer look at to do them properly.

Finishing notes:

I vacuumed all the dust up from the enginer bay and all around. I used a dremel with a cylindrcal sanding disc to smooth out the edges. Although this was good I am going to get a small file as I need to smooth our the space between the ribs that were cut. I will also paint anything cut and let it dry before finishing the install.

I spent about 2 weeks agonizing over using different angle grinders or a jigsaw. I went with the angle grinder because of the many videos I watched and it was noted it was more likely faster.

Additional Notes
 

Some new notes and observations:

On my Z, a 2009, the outer most edges of the vents where the rivets must go are inside of a underhood rib. It'll be difficult to hold a washer in between the rib and the hood skin unless you cut the rib back some or cut some access holes. I chose to make holes and a use a special tool but I believe cutting it back or cutting an access section may be easier.

What I ended up doing was marking where the middle 2 rivet holes would be by using a long piece of painters tape. The outer corner rivet holes were marked by drilling straight down. You may be able to do this for the middle holes as well. I drilled small holes, 1/8", from the underside. I then took a step drill bit and drilled a larger hole. Be careful because you dont want to go through the top of the hood, I only stepped through 3 or 4. I worked up to a 1/2 inch hole using regular drill bits. I then used a 1/4" ratchet extension with a rivet taped on the end and used it to hold the backer washer in place while I used the rivet gun. The needle nose pliers I used were too thick to open up enough to hold the washer in place. Some tape was left behind but no one will see it.

Additional template notes - On the template there are 4 squares in each corner and these represent the corner rivets. You need to keep these spots marked on the car as it'll help your square up the vent placement. Luckily I center punched these holes from the template and had them marked.

Riveting - I did this by myself but if you can get someone to assist that would definitely make this part easier. There is a note in the instructions that mention you should tape around the rivets to prevent the rivet gun from jumping and making a mark. Absolutely do this.

Installed the center section. :tup:

More pic's of center section. :tup: Still have to do the side vents.

Nice Job
Looks great.
Cut holes in my Cf hood for low profile hood pins.
Nerve wracking.You can not screw up.

Side vents installed. :D

Finally got time to install them, by hiring a friend to do the install :icon17: It wasn't hard having the right equipments.

I know this is a super late reply, but I installed mine, and after a few weeks of off/on rain here in TX, I killed one of my plugs. Now what happened was, water leaked down on cylinder 2, and it went past the coil boot insulator, and did have some build up. So I threw on a very minute bead of silicone to help seal it up. But just wanted to give you guys a heads up. My Z is my semi daily driver (I have another car, but prefer to drive the z, I'm sure you guys understand lol), and does NOT get parked in a garage.

Mine is out in the rain right now. Have eastwest's Z parked in my garage for the night.

Hmmm, I went around and put dielectric grease all the connectors, didn't really thing about actually pulling the coils off and under them. I guess I better do that too.

Aren't you worried about the silicone making it tough to get the coils out when the time comes to change the plugs?
