So i popped off the banana muffler & fired her up on the driveway, ferking heck thats loud. I reckon 105-110db. Presumably thats how loud it'd stay with megaphones or some straight pipe!! Dang. Sound good though (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) just need earplugs. Question is how loud is too loud for AX / track venues. circa 95db?? Didn't see anything specific in PCA or SCCA rules. |

fyi just pinged the PIR (Portland) folks here's their response...
103 measured 50 feet from trackside for most events. Drags after 10 p.m. and Monday events are 90 db...the permanent monitor is almost at the 1/8th mile marker on the drag strip, on the west end of the 2nd grandstand. Clubs during race events usually also measure on the back straight near Turn 8. Hmmm open mufflers or a shorty straight through muffler might not be that far from 103db...
