I don’t think so. I had a problem finding pulleys to get to 6% over. I have a friend who is going to look into getting some pulleys CNC’d and if we can get it done for even close to reasonable money (Id be willing to pay a hundred bucks for just a smaller water pump pulley to get me to 20% over) I’m going to speed my stuff up. Even though I have zero issues now, I want as much flow as I can get, because I believe that is another way to to reduce localized hot spots. When the flow is moving, you have more turbulence and that is good.
When I had my engine on the run in stand, I didn’t have a thermostat in it. I had to put one in because I couldn’t get any heat in it. Anyway, I took the cap off while it was running and even at just 6% over, the coolant was moving. Faster than I had ever seen before.
