Looks good, but it wouldn’t last much on the l trails I usually ride.

Why?
Just use a proper (not resin only) and larger brake disc instead.

What is the cfm of that nozzle going at 20mph?

Replace those terrible excuses for rotors.

While a neat idea, the rotor needs to be cooled way more. After a descent, you can still touch a caliper with your hand briefly, but a rotor will burn you right away.

Unless you’re going at Moto GP speeds, this is just silly.

Magura rotors are standard 2mm with wear limit of 1.8mm. The shimano’s you have a default thickness of 1.8 , just updating the rotors to proper magura storm at least would give better performance upgrade imo.

Does it somehow clip on? Or how is it secured?

Cool. I think the cooling ability of a caliper is not much better with a scoop compared to just air brushing; I think you might find real help in aiming to cool the rotor or to cool the pads (stop glazing). Too lazy with CAD to do that though…

Not really sure that it would do much on the steep trails, as you end up going slower, and using the brakes more, but still, cool little project especially if you have done all the math to go with it related to airflow etc.

Put some Galfers on there

Useless, sorry…

The frontal area of the intake is minuscule, and seems smaller than the exhaust, meaning the exhaust speed will be lower than the intake… and the air will never make it to where you think it needs to go.
For something like that to work you’d need a SIGNIFICANTLY bigger intake, and bring the air much closer to what you’re trying to cool down.
