Cooling air inlet duct opening.

[Flyboy66]

I am cutting the lower cowl for the radiator scoop. I would like to see the finished work (painted or not) of how people contoured the inlet, if anyone is willing to share. Did you use super fil on the edges? I was going to round the inlet. Do most make the transition a sharp corner, or a rounded edge? Does it affect airflow either way?

I did see tropicals work. If you did it same way as he did, no need to reply.
