Yet another test of the Beehive valvespring...
In the new Sept'04 Hot Rod.
They used the 1.445-inch diameter Beehive at 1.850-inch installed height. It reduced the seat pressure from 210 to 160, open pressure from 405 to 360. Testing was done on a hydraulic-roller cam.
The RPM at valve float increased from 5,800 to 6,600-plus RPM.
