was curious if anyone knew if the k5la takes much more air over the k3la. would a person need a bigger tank to support the two extra horns?
Yes. 2 more horns eats 66% more air.
5 gallons is about the minimum for a K3 and 8.5 gallons for a K5.
I had 8-9 gallons for my K5 and wouldn’t want any less.
here is a vid of going from 200psi to empty, enough honk time imo!~
but if you had a 8.5 gallon on a k3 - woo wee!
