Re: 285 whp!

Rally Bob:

Would really be interested in the insights Jack and team have about the overheating problem with the EG33. I have a sense that the problem is located in the engine, or at the inlet to the water pump. If it is in the engine, there might be a portion of the engine that is inadequately served by cooling channels, and overheats locally, causing local boiling of the coolant and steam pockets in the coolant stream under hard running. A second possiblity is that there are coolant passages that, because of their poor hydrodynamic design, cause local cavitation at high flow. Another possibility would be that at high rpms, the water pump is cavitating. The first problem probably isn't solvable, the second might be solvable by machining some of the coolant passages in the block. The third could be solvable by an electric water pump.

As I have continued to track my SVX, the overheating problem has gotten worse. Maybe I'm driving the car harder, or maybe something is deteriorating. Even the PWR radiator didn't seem to help. At this point, I have given up tracking it. Overcoming this issue is key to my keeping the car. Even though I do have a new track car, it's open and isn't really suitable for heavy rain. I loved being among the fastest cars on the track when it got wet. Loved passing Corvettes. But, soon as it dried out, my radiator boiled over.

Anyway, next year, I'm going to upgrade my closed trackable car alternative. I'll either go into a major refurb of the SVX, if the overheating can be overcome, or buy something different. So, the overheating issue is very important to me. Would love your insights.
