I am using the dimpled ports and picked up .2 db's with them over the regular but hell .2 could have been a difference in air temp or humidity or a million other things.
im just going for regular aeroports. no sense in looking for 10ths when im going to be a daily beater.
the dimples on a golfball actually INCREACE air resistance.... just a friendly FYI. without the dimples the ball would go wherever it wants. with the dimples it gives you more control of the ball based on what spin you put on it and what type of ball you use(diferent balls have diferent diple patterns.)
based on that information the port should actually give you slightly more air resistance which should make the port "seem" longer than it is.
This makes me think of that Mythbusters episode when they dimpled the car.
the original aero ports are made in italy and very hard to get in the states ,i have 2 of them and have tried them both in the same box and the real aero's were louder
The theory is sound. You actually want turbulence at the terminus'. But you want laminar flow through the pipe. That's why they don't sell dimpled pipes (or want to dimple the entire slot port). I haven't tested these, but should be good for a few tenths. Probably not worth the added cost in a daily.
And FWIW, the dimples on a golf ball increase the turbulence, but decrease drag due to the size of the wake they create vs. a smooth ball. but... ladies like smooth balls :)
i kinda wish they made the dimpled ones in 6"...
guess this may qualify as taylorwin V.2 huh?
my grandpa was crazy good at golf. i **** ***. well not at mini golf. on the putting green i own. lol
