2023

Billy Blair is a man with a lot going on. He owns a pool building company that brings in a serious amount of business in Southern California and that allows him to play around with some other fun things like cable TV shows and, well, performance boats. We’ve seen a few of his boats over the years and they are always extremely well appointed and often understated in many ways.

All summer you’ve dreamed of passing all those boats that have blown by you since June. Now that time has come. You plunk down a large stack of greenbacks for a nasty supercharger and wrench all weekend bolting it in. Now comes the moment of truth. As you tear down the lake, all eyes are on the gauges, and the oil pressure is heading south too quickly. What could be wrong? You let off the throttle for a bit and all the vital signs return to normal.

We’ve ran into this exact scenario before. We installed an R-Tech Supercooler on the ProCharged Dorr’s Marine Engine 502cid motor in our Baja 250ES. The install was a huge success with a whopping 9mph increase in top speed. The boat worked well, but what we weren’t expecting was the huge increase in oil temperature from the gain in horsepower. If we had stayed on the throttle for a good 5,000-plus-rpm run, the oil temperature would have shot for the moon and oil pressure would have dropped to an uncomfortable level, forcing us to back out—what fun is that?
