Once I get mine fitted I'll do a db check....I have an iPhone app that's pretty accurate so will let ya know buddy.

Downloaded an app tonight Tony so will get a sound reading when I go back to work Tuesday. Will have one of the lads set her to 6000 rpm. What sort of distance were they away and at what angle?

At 4500rpm 45 degrees at 1m I registered 89db valves closed and 98db valves open
