i just put some new jets into mr peepers, and was rewarded with a stable idle!



the iphone app db meter was pegged at 150db....

is that a free app? I'll have to borrow a phone when i get mine running.





150 sounds pretty unrealistic though https://www.nopistons.com/forums/pub...1047683561.gif

yep its free, made by hearo's the ear plug people...

It reads high, I was using it for some air conditioner sound testing, and it was about 50% high compared to a real DB meter.

My p-port car at the track was 116 db at the starting line.

that is not surprising, they want to sell earplugs.

150db is crazy loud

drove it for the first time today, either i'm deaf, or its not that loud in the car https://www.nopistons.com/forums/pub...>/rolleyes.gif

Yeah, I'd be a tad skeptical that it's as loud as 150. Crazy that you can use an iphone as a db meter, though.

based on that chart its between motorcycle and pain

LOL







194 loudest sound possible



How do they know that? What could make this?
