The oil pressure is the result from the oil pump from Katech. We had a oil pressure problem and were running 15 PSI at idle with the LS 7 which I was told that it was the minimum pressure required from Chevrolet, we seized the motor, we were running around 45 to 55 psi with the stock pump at higher RPM, so the problem was when it idled. I contacted Katech and this is what they recommended, their high volume pump. It had just come out, and talking to them, they said they developed the high volume pump due to the low idle pressures when running the oil cooler and dry sump system. We did discuss all the routing and size of the lines with Katech also. I am not sure about if you have too much pressure, I will have to get back with Katech and ask them unless Fran knows this answer. I have been told by the original motor builder that the oil temperature should not exceed 240 degrees or the oil will start to break down. I do not know if this is true or not. I have found the problem with the automotive industry is the amount of wrong info you are given, so all I can do is talk to the people in technical departments, explain what is going on and go with what they recommend. I can say this pump is what is being run in the Katech engine they build for the Corvette race team. I can also tell you from experience that 15 PSI at idle is not enough pressure for the exact set up I had. Randy I agree all you need to do is provide oil between the surfaces, not flood them. I have found that oil weight is a direct effect to oil pressure. The motor builder we used here in Atlanta said to run 20W-50 VR1 Racing oil which I do. I will need to check out if we need to change weight oil. I think this discussion on oil is very helpful to prevent oil failure issues for everyone before it happens, it gets very expensive, like I have already experienced, we had to replace everything in the motor except the block and bare heads, and intake.
