Verus Engineering Brake Cooling Kit

Due potentially low price/simplicity of install, such kits may find much wider customer share. Meanwhile i myself probably will wait for few more prioritized spendings to clear and then aim for full kit.

I wonder if such a kit could actually deliver more air flow...? Seems like a good idea from this end.

Do you mean more air flow than stock?
There's already data on these forums that the porsche ducts work.

Or do you mean more airflow than long brake ducts from the front bar? The control arm ducts might deliver more air, but effectiveness could only be measured by have the same car on the same track with the same driver do the same lap times on the 2 different setups. If you do that then there's 2 ways to measure - use race pads and measure temps or use street pads and measure time it takes to fade.

Probably impossible for Velox to make money on such a kit given the Porsche scoops work well enough, are easy to install, and cost less than $30

I meant the long brake ducts and the front. Wind tunnel testing with a pitot tube to measure air speed, than translating that to air volume, would likely be the only way to get reliable data. There's just too many variable in having a driver on track.


But, as the other guy said, the Porsche ones cost $30. There's not nearly enough demand for brake cooling to support either type of testing for a $30 product.

They achieve two completely different things different ways, so volume of air is absolutely irrelevant.

They cool the brakes by directing air to them, correct? And the cooling rate will vary directly with the air flow? What do they do differently? Or do you just mean that they direct the air to different locations on the rotor?

I too am confused

Ultimately, this is the case here, I see no reason to compete with a unit like this.

The Porsche scoops, or anything similar, directs air towards the rotor surface. The rotors get the vast majority of their cooling from the inner vanes. Our unit forces the air into the center part of the rotor, which then shoves ambient air throughout these vanes. This cools the rotor significantly more than throwing air towards the rotor. Is directing air towards the brakes significantly better than nothing, most definitely!





The two styles of cooling are vastly different, with one being far superior for heat rejection.

Hope this clears this up a bit?!?!

Thanks,

What if you used both?

[Tokay444]

Even rotor cooling is critical, and the only way to do that is to direct air through the center.
They are far more susceptible to thermal cracking with uneven cooling solutions.

I've done this in the past and it works. I don't anymore because 1) the hoses are in the way of mounting the scoop, 2) I found with the scoop I got less pad wear on the inside than on the outside, requiring pad swaps.

Which backs up the uneven cooling concerns.

While the front end was off last weekend, I added some mesh to the fog light inlets. It's not very noticeable, it shouldn't impede flow, and will catch anything large that otherwise may make its way to the rotor.





I sandwiched it between the fog light duct and the 3" hose. The hose clamp holds it in place and it is holding up well so far.

Should have some shots of some AP Racing brakes with this kit shortly as well !



Thanks,
Eric

We installed the AP Racing/Essex Sprint kit with our brake cooling kit and fitment couldn't be any better .
