Hydro-Boost Noise

OK - I put a hydro-boost on my '71 Cutlass Supreme to get better braking power. When I accelerate,a noise is created that sounds as iff a fan belt is slipping and "catches up". It starts as a high pitched squeel, then lowers in frequency until it stops. Belt is tight and dry. Brakes work fine. Almost sounds like it is associated with the hydro boost building pressure. Any one have any ideas or had this problem before?

Sounds like you need a insulator on a metal hose, check to make sure all lines are not resting on the body, I ran hydro boost for years and never had that problem, My motor home is still using a hydro boost that I installed (1973 Barth)
