R1 lip... how effective and what is the vent for?
To me this piece is cosmic. I hope it is both functional and cosmetic. Please someone enlighten me. I have an idea to use the vent for the intake of it isnt really doing anything else. Brakes? I dont see how. Down force? Would be cool, but I dont see it making a significant difference. Maybe slightly by deflecting air which in theory could help.
I have possibly found some low profile ducting for a skunk works project
also there seems to be some railing underneath. Am I perhaps missing some sort of ducting it comes from factory?

Montego. Your awesome. Sorry you had to link it. I should've searched damnit. Agrees with everything I am thinking so I appreciate it!

Now if I can just find a good video or accurate diagrams of the nose and hood for flow. I have researched it a bit on the site and not too many people agree of which part the air separates and becomes a low pressure. Read on why I am wondering is the attached pic. I know a few have mounted naca ducts on their hoods, but they all seem to be back too far. This pic is what I am curious about. If this duct in its position will maintain function throughout the speed ranges of day 0-150mph. I will continue to search, but I would love to find a video of such or CLEAR diagrams.

Lol, no cutting factory hood, but I am going vented hood and considering something similar to pic with a fiberglass ks style hood. I will try some other ducting 1st though, but I will be going vented hood eventually. I am astounded by the temps I am seeing with my experiment.

Re-amemiya makes sleek light kit with duct for intake. You could probably snake a 2" tube from the lip to the intake, but I think you'd be swimming upstream and cutting things. I think it would be cool to get some hose connections made for the stock brake ducts, and to backing plates for the stock brakes. The stock 16" brakes aren't really good for more than an auto-x or spirited drive, without some ducting.

Thx Narfle, I am looking into that for sure. I am in the middle of making a back plate for my pettit Intake right now. Trying to isolate the filters a bit.
I am undecided what to do with the brakes at this stage. I haven't had her on the track yet, but I have heard they get a hurtin out on them.

Thx Sgt. I never saw or heard of them off hand. I will start looking around.

FWIW regarding brake ducts, your pads should be heat matched to the conditions. e.g. if you don't have ducting, you may need a high heat pad if you are creating a lot of brake heat.
It might be easier to get brake pads matched for high heat vs. installing brake ducts.
For example: https://www.tirerack.com/images/pdf/...und-Charts.pdf
I run DTC-60s in the front which i found were awesome unducted. I have since ducted the fronts and not sure if the heat range of the pads is now too hot. I just bought in IR temp reader and will be checking (whenever i can get back on the track). (It should be noted that i found these pads aren't meant for the street. You just don't generate the heat needed to provide any stopping force)
Also, brake ducts are really unnessary for a street car (again if you have the right pad for your use)

Nice!! Looks like a lot of work. Doesn't look like it would be as much work to run it up to the slot for the intake though . This is kind of what I had in mind for the intake to begin in with. I will be on the drag strip before the track so I take and my temps are more important as of now.
My temp logging is coming along nicely and I will be posting some stuff up soon. A mod like this to the intake will be pretty easy to see if it is a go or a no. I think the temp will show an immediate change if it is worth it. As of now the avg. Intake temp is only 4°F different than the temp around my uim. This included traffic and a bit of heat soaking. The avg. with no heat soak or heavy traffic is about 10°f difference.

Tom I dont recall seeing any brake duct in your build thread. I will have to go back and look at it again. You have the factory ducting?

Remember the FD has really good stock brakes. They will take anything you can give them on the street or at a drag strip, especially with good pads. You really only need to look into more serious brake ducting and larger brakes when doing SERIOUS track time where you are going to triple digit speeds and slowing down hard repeatedly for 30+ minutes.
I beat the hell out of my stock brakes on the Dragon at Deal's Gap every year and have yet to have them fade on me. But, again, there's a HUGE difference between the heat you generate there and real, dedicated track use. Even at the drag strip slowing down from triple digit speeds you'll be fine.
I will say that it's worth having the proper R1 brake ducts with the R1 lip so it looks correct instead of just seeing the ground through the duct.

Thx Dale. It will be awhile before I get to serious tracking. Drag strip and back road blasting for awhile. I am not into looks as much as function. I agree looking through them doesn't make me feel complete in that aspect. Dont get me wrong, she is a incredible looking creation and I want to keep her looking that way. Minimize Frankenstein.

Got it. Thx Tom. I think you did pretty damn good on it. I will start searching for a duct I guess.... or 2.
