Tial Q spring choice

Post by roortube »

Who runs what spring in their Tial Q? My engine idles at ~16 in/ng vac, but frequently operates at more vac than that when commuting. I'd like to avoid the valve being open during cruise but still get good response. Suggestions :idunno:

My car idles with 15in/mg, which according to the spring chart is the white spring(-8). However, I'm using the black spring(-6) for the best response up here at 9k' alt. From what I've read, the chart is a guideline or starting point but just use the weakest spring possible without getting any valve creep.
