What do u think about aero fans wheel hub?
This one by @Alan_Dove
I think calling it an aero war is a bit of a stretch personally.

The bodywork certainly didn’t win any of the mains this week, so yeah this isn’t a aero formula yet. What fairings was Turney using? Previous homologation KG.
The wheel fans feel gimmicky but certainly a cool little idea.
Great idea, love to see people trying new things! This is a simple, brilliant and cheap idea that I don’t see creating any “aero war” at all…think about it, wheel manufacturers could have embedded the concept into their casting to begin with, and it would be called…“evo” rim without any complaint. Love it! Is it effective/worth it? No idea, but it’s clever

The front wheel fairing trick may play a part on some surfaces or in higher temps. Maybe let you start higher and maintain versus planning for the heat/buildup. Don’t think that was an issue most were having when it came time for mains this weekend. Looked to be cool and slick which wouldn’t be the place for wheel cooling.
Do all the fairing differences even matter much? Nope. Tiny fractional difference. I see a lot of parallels to fishing tackle in the bodywork stuff. Fishing tackle is designed as much or more to catch fishermen as it is fish!

Until we get drivers out of the kart, or at least out of the wind… gains elsewhere will be incremental.
Everyone’s looking for a couple thousands here or there, but it’s hard to measure.
Front tire deg was an issue for many people I talked to. This could possibly aid it.
Previous homologation Eurostar (Parolin) Dynamica. We haven’t seen the new Eurostar yet.
I like that’s its 3d printed so theoretically anyone could do it relatively cheaply. I’d like to see it ducted (also doable with a 3d printer).
Do i think it’ll make any difference (or a positive difference)? Given that it must be draggy, I’m not sure the cooling is worth the drag. Hard to know without simulation or testing.
turbo fans, on a kart! A project I started early this year, felt like it would be cool to see something like that on a go kart.
did it make a difference?
about a tenth and a half
tires were marginally cooler (0.5 psi - 1 psi lower), but hard to check rapidly because of the design.
It was tested on a cadet kart
I want to adapt it to a senior rim and revise a few parts of the design overall, hard balancing this and school exams…
This I like more, because its as much about drag reduction as cooling.
I tend to drive rears off based on setup preference and driving style.
Thought this was a cool idea but I run solid wheels (MXC) and can’t help but think the impact will be minimal on them with nowhere for the air to go.
A tenth and a half is a lot, that feels like it needs more testing. In my head, the benefit wouldn’t be outright speed but consistency and keeping the tires from falling off as quickly, I can’t wrap my head around how that would translate to straight laptime gain. I love the idea of turbofans in general, being able to put them on a kart would be pretty sick.
Unrelated but I’ve thought about cutting white vinyl to make whitewall tires just for the hell of it, maybe if I start getting back to a kart track consistently I’ll see if I can do it. Turbofans with whitewalls would certainly be a stylistic choice at the minimum

If every magic trick that was worth a tenth actually improved lap times by a tenth, I would beat the field by 5 seconds a lap…

Turbo fans and RWB “idlers” spray painted on the sidewall. Then you could bolt a second rear bumper on top of your rear bumper and you’d have quite the tribute to Nakai in kart form.
