k_pt in my experience radiator height compared to the engine is all but meaning less. So long as the fill point is the highest point. I know guys that run V8 Chevys in airboats and they put the radiator under the engine. I have a v6 Samurai with the radiator lower than the engine and I don't have any problems with it. You just need to make sure you have the fill point high enough.
Not sure what you mean about the boost piping it has no mounts to the engine just rubber couplings. Also I don't know what ASV stands for.
PickleRick I made the hub on my lathe. I wish I had a mill. I have a powerful drill press that I use like a make shift mill sometimes though.
ok, always thought the radiator at to be at the same level as the engine, thanks for the explanation.
About the boost piping, I don't see any rubber between the engine and the intercooler, wich means, all the vibration that comes from the engine, will go through the piping and end up on the Intercoller.
ASV is anti shudder valve, cuts the air that enter the engine, when you turn off, to avoid engine shaking when you turn off the engine.
