CPP Hydroboost problems

[CPPAaron]

Info from Our supplier:

It’s not the hydroboost unit making the noise, instead being the March PS pump and reservoir (being where the problem is). What this gentleman needs to do is to reduce the flow on the pump by either installing the Heidt’s PS101 valve or swap out the actual PS pump output fitting in the pump to one with a smaller orifice (which will slow the pump flow down back to stock levels):

Reducing pump flow back down to stock levels will handle a good majority of the issue, though the installation of this reservoir below in place of the March remote reservoir is also HIGHLY RECOMMENDED:

We have had some customers experience difficulties over the years when using hydroboost systems with mini pumps and the typical aftermarket remote reservoirs (low on capacity and do not offer proper de-aeration engineering). Some have managed to get their setups running decently, though most have found that the only way they could get the PS system to work right is by swapping out the remote reservoir to this unit from PSC with the internal filter that has the excellent side effect of straining air out of suspension in the fluid:

You also need to make 100% certain that all fittings, hose and adapters between the reservoir and the PS pump have a MINIMUM ½” inner diameter, otherwise the PS pump will cavitate and always run noisy (yes, I am only talking about the pump feed hose between the reservoir and the PS pump)(all other hoses in the PS system will be AN-6 or 3/8). Some customers I have worked with have stated that the remote reservoirs are shipped with inadequate AN-8 sized feed nipple with less than a 7/16 ID = guaranteed cavitation issues per the bottleneck inside of the adapters (the factory usage of these pumps ran a minimum 5/8 ID in the pump feed by comparison).
