Did someone say gyros? Damn, I'm hungry.

 

do vortex generators actually do anything?

 

Yes, at high speed. But the drag-lessening effect is minimal, especially when you consider rolling friction of tires, drag-inducing protruberances like rear-view mirrors, spoilers, etc.

On aircraft they can reduce fuel consumption noticeably in the long-run, averaged over several trips, but in a car I doubt you'd ever notice any gains in mileage or speed at all.

 

Yeah, they are quite useful on jet aircraft.

Probably not worth it unless you plan on fitting a jet engine into your 8.

Just wanted to post that, ya, the new 09s have shark fins from factory. Dont know about the R3.



So what yall think now?

 

hahaha... priceless

 

If I can get any HP , I'm getting it . hahahahahaaha...........

 

Ugh I think I see many 09's and shaved sharkfins in the near future
Maybe it's just me, but It just looks like it was stuck on the car with 3m adhesive, like a pep boys item.

 

I still don't like it, and and they probably put a hole in the roof to make sure you could never take it off... Still, it is a better place for a sat radio reciever.
