i have been working on porting the outlet of my blower using a rotary file on a router. so far i have removed the H-Bridge opened up the outlet and just cleaned everything up.
Question #1 on the outlet itself after porting it it leaves a sharp 90* angle. will this cause turbulence inside the blower and slow the air going into the lim down?
#2 what should i do with the slits? i have heard if people filling them in with epoxy i don't know if thats a good idea though
