Oil Pump FAQ
Q: What is the turn-around time on a pump?
A: 2-3 weeks
Q: Can I get my exact pump returned to me?
A: Yes but it extends the turn-around time.
Q: How long will the performance of the pump continue?
A: The performance of the pump should remain at the higher level throughout the service life of the engine.
Q: For race engines, should the pump be re-examined during tear downs?
A: It would be advisable ESPECIALLY if the teardown is for a failure and not a routine service. Re-inspection of pumps being used in race engines is routine for us. The service charge is for this is minimal.
Q: What improvement can I expect?
A: Test consistently showed flow increases above 20%. With a cold engine it is common to see the oil pressure above the bypass valve value at IDLE (60-80 lbs). With the engine at operating temperature, the oil pressure will typically be above the bypass valve value on a 6000 rpm rev. Of course, clearances inside of the engine affect the oil pressure as well as piston cooling jets, 3.2 liter chain tensioners, etc.
Q: Can I just install a 964 pump or a Turbo pump as opposed to using a ported and polished pump.
A: Yes, and there is a machining procedure to accommodate the different pump. There is however a caveat to installing an over-sized pump in a different generation engine case/system. Download and read our discussion on the subject.
Q: What is the warranty?
A: As with all race/performance components, warranty is limited to the failed portion of the pump or the pump entirely.
Q: How often are core charges applied?
A: Rarely. Most certainly they are applied if the corrosion is excessive from submersion in water or the engine has had a rod bearing failure and the connecting rod has struck the top of the pump.
Q: Suppose the pump is partially damaged.
A: Upon inspection of your core and we discover a portion is damaged beyond repair, we will stop and notify you to discuss options.
Q: Is it normal for the pump to be stiff when rebuilt?
A: Yes, a combination of the friction reducing coating and the preservative often cause a stiff spot. This in no way affects the performance once the engine is started.
Q: What types of payments are accepted?
