95db@50 ft, unloaded 3500 rpm
That isn't too bad. A small HP low backpressure muffler should handle it easily. The small block cars will have it a lot easier the the BIG BLOCK's, as always. LRP is 85-89 (depending on who you talk to), at the side of the track, anywhere they want. Usually, somewhere like just before the brake area on the front, out on No-Name, or just over the crest of the uphill, all are areas of high RPM/load and full throttle. NHIS is at start finish, same high RPM/load, full throttle but allow 99 (also enclosed by the grandstand/wall and pit wall...like a sound tunnel with reflected pressure waves).
This will be a convenient test area for Road America too. And we can all go over to McJohnnies house for dinner and TnT's!
