Stillen's Brake Cooling Kit

Nikon FM

I have access to a very basic lathe and milling machine (not cnc). I bought a big chunk of black Delrin and am going to have at it in the next two weeks.............................just got tired of waiting and really hate the look of the DIY stuff so far.

Stuff to make:
2xInterface pieces to OEM front grill with the two pieces removed....will utilize OEM fastner location at top.

2xflange to penetrate fenderwell liner

2xflange/duct to target back side of rotors without interfering with wheel movement

Not sure how long this will take but will hopefully be able to knock it out within a month..

Keep us posted on your progress. 90% of it I could put together by modifying off the shelf racing parts, but it is the hub flange duct that needs to be very specific to our cars and is the PITA bit.

I was thinking of going with a 3 inch intake, 2-inch reducer (increase air velocity and make it easier to route the duct) and then figuring out a solution for the hub.

Where would you initiate the 3" intake? Popping out the pieces outboard of the fangs without additional cutting is what I'm going for to keep the look clean….possibly would minimize the flow performance though?

I was going to reduce the x-section area from the fender liner flange to the end of the duct nearest the rotor to increase the velocity.

This is not going to be a quick turn around based on my current schedule but I'll show pics when I'm closer.

I was planning on initiating at the fang. The fang isn't round but the shape is smooth enough that I think it would be efficient even if the shapes aren't a perfect match.

Putting the reducer at the fender liner would be a good place for it, there seems to be enough room up to that point for the 3" duct.

Yeah, the transition to a round pipe will occur just after/behind the fang opening and should be the size of a standard ID for a hi temp duct (not some crappy dryer hose)….something like this:

Yep, love that McMaster web site. They did a brilliant job designing it and putting in all the data.

This is what I was thinking to screw in behind the fang.
