[Healeys] Non Healey Question...Blower Bentley

[steveg at abrazosdata.com (Steve B. Gerow)]

Mike,
Quick perusal of my copy of The Grand Prix Car by Laurence Pomeroy: all the 
roots-blown cars have these popoff valves on the manifolds. The blower is 
positive displacement so all that intake has to go somewhere on deceleration.
