I had the slobber tube extension installed two year ago when I was at Gaffney. Their suggestion because I always had them wet steam radiator and CAC. This past Oct. I got a high temp alarm while going "over the hump" from Parumph to LV. Okay it was probably 100 degrees outside and I was sparing the horses but thought I was keeping the r.p.m.'s high enough. I backed off and alarm cleared but I also reached the summit. It was all downhill from there. I did some research and am leaning toward still picking some 'junk' up between CAC and radiator. Hoping to get to Gaffney in the spring and we will see what we find.
I find it interesting they when the electric route first. I would have started where the physical act of cooling is initiated and worked back from there.
