The noise whine from my supercharger is good, but really loud. At Blyton I trip the meter at 93db, so am loath to go to other tracks such as Bedford, only to be kicked off because of the whine. Exhaust noise is no worries, passing ok at Cadwell static check.
How can I reduce this whine (other than taking my right foot off the pedal), still keeping the power delivery?
Would a different air filter help (I use a pipercross cone filter)?
Any suggestions gratefully recieved.
