Perranwell had to come from 2-0 down to maintain their unbeaten start to the season on Saturday.
The visitors stunned Dave Fisher's men with goals by Joff Bunt and Shaun Lawrence before the home side started to regain their composure and pulled a goal back just before the break through Mike Brewer's free-kick.
The game then turned on its head when Perranwell won two penalties in a three minute spell at the start of the second half.
Both were converted by Mike Brewer to complete his hat-trick and there was then only going to be one winner.
Midway through the half TJ Wilson made it 4-2 and Steve Brewer added number five from an acute angle.
Jake Harvey completed the scoring by heading home a Darren Martin cross as Perranwell ended the game in total command.

Perranwell: S Easterbrook; D Martin, TJ Wilson, H Gibbon, J Hoon, S Selley, J Harvey, S Brewer, M Brewer, I Boon. Subs: C Adams, D Senior, C Grose
