We were playing with a db meter today and on the A weight setting it’s idling around 80db 40cm back at a slight angle. On
the way up to 4000rpm it peaks over 100db and at 4000 it is in the high
90’s. Will really need to keep a close eye on that and do some research
on exact testing conditions for SVA. I think it’s pretty boarder line
right now. I did find blocking one of each of the pipes on either side
with my hand made it significantly quieter (by ear anyway) So I may
just need to block those off for the test
