Has anyone ran both in a S366 or similar? I can pick up a billet wheel for a good price and was considering it if it will make a noticeable difference in sound.
Seriously though if you want a whistle. Put the john deere cut turbine from the airwerks 177281 or 177275 you can keep the divided housing for spoolup with a cut turbine it will flow a little better up top and whistle.
kinda like going to a 10 blade from a 13 blade on our 3788avnt.
call evan or phillip I am sure one of the boys will hook you up
