I don't like telling anyone what to do, I try to provide information so the viewer can make an informed decision. Using the videos information as the basis for my opinion, I won't be looking to purchase high volume oil pumps. I will be using standard volume ones and making improvements... Which I will have to show at a later date.
Please understand your question is vague. So I'll give you the short answer. YES. Regardless if it's your Kawasaki 18hp lawnmower or 32v Mercruiser ZR1 LT5. The engine needs as much oil flowing through it as possible. Thin oil. 5-20, 5-30, 0-20, etc. 25 years as an ASE Master, 17 years as a Ford Automotive and Diesel Senior Master technician and 28 years building(1996 to present,these credentials overlap) race cars is the experience that let's me say, "YES".
Sorry, I didn't realize you were passing on someone's material. I thought these were your ideas. I'll make a few contradictory statements in hopes that you'll search out what's right. Let's begin. Pressure is resistance to flow and they are directly related. The more pressure you have the more resistance to flow. The less pressure the less resistance to flow. So your statement ending at 3:42, "your pressure doesn't change....you just have more flow," is false. The oil clearances in the engine will determine the pressure reading you see. You stated that correctly. However, if flow is increased then pressure is decreased. Pressure being equal to resistance of flow. We'll start there.
You are referring to flow out of a system. The pump, which I am referring to, is increasing flow into the system, which will cause the pressure to rise if that flow is not checked. Hence, the need for a relief valve. The spring pressure ultimately dictates the pressure as the bearing gap only changes with temperature, yet that is by a small amount. So, set restriction with variable flow into that system will equal rising pressure if the flow is not bypassed. In fact, there are numerous examples of exceeding 120psi at idle when a bypass valve is stuck shut. And you are right, this is nothing new. It's just a greatly misunderstood subject. I'm sorry my wording is not constructive to your understanding of it.
So do we need high volume oil pumps if most of the flow is going down the bypass?
