PIR events range from bicycle races to car shows, drag racing, sports cars, motorcycle road racing and motocross.
Their popular Late Night Drags, run most Friday and Saturday nights from April through October, let you run for fun, race your friends or test and tune. Their regular Wednesday night NHRA ET bracket racing program is for points and purse. For a slow-speed tour of the track, come to the Holiday Light show evenings between Thanksgiving and Christmas for a 5-mph view of great light displays.
You don’t need to belong to a particular club to join in. For your fee (they vary, but plan on $250-$350) you will get a 20 minute session each hour. Clubs handle their own registration, and a list of clubs and their contact info is below.
There is on-site parking for 2500 cars and another 2000 spots within easy walking distance. The PIR road course is 1.967 miles long with 12 turns.
In a 1989 agreement with North Portland neighborhood groups, PIR acknowledged the negative sound impact on nearby neighborhoods. They set up a neighborhood trust fund whereby PIR agreed to contribute cash to a trust managed by North Portland Neighborhood Services. These funds have been made available to the public via North Portland Neighborhood Services with an annual grant cycle for community projects and events.
Four varianced events include one event at 110 dB, two at 112 dB and one at 115 dB. At a 115 dB level trackside(the Portland Vintage Racing Festival weekend of July 27-30), sound levels at the closest residence to PIR should be 70-75 dB, equaling normal traffic noise levels measured for homes along Columbia Boulevard. It is 10 dB higher than basic City Code allows for commercial/industrial noise to a residence.
The Columbia River Classic/All British Field Meet (112db), occurs on the weekend of September 2-3. PIR operates a fixed microphone, 50 feet from the track, just past the “B” bleacher on the front straight. This spot was chosen by an independent noise consultant to best capture highest sound levels from the various kinds of events held at PIR.
