You MUST have a bypass-type of valve to convert an Exa-Pump** to a turbocharger oil pressure pump for creating fully independent/standalone turbo system set-ups.
The Exa-Pump® Pressure Bypass Valve is a compact, reliable, inexpensive, and easy-to-use add-on bypass valve solution for any Exa-Pump®*. This bypass valve is infinitely adjustable from 10psi-40psi for covering uses with either journal-bearing or ball-bearing turbocharger styles. One Exa-Pump with this bypass valve can supply a single turbocharger or twin turbocharger set-ups. Important to note that with the bypass valve installed the pump's ability to scavenge oil is not affected - it can still be mounted above the turbocharger. Also note this bypass valve can also be retrofit to any regular-size Exa-Pump previously made over the years. Installation typically in under 10-minutes.
**Regular-size Exa-Pump only, not Exa-Pump "Mini"
