This is maybe going to sound like a weird dumb question, but here goes.......... Don't shoot me too hard! There seems to be a lot of controversy over what intake valve spring pressures to run in the face of high boost pressures in the intake runner. Some say just run what the cam manufacturer recommends. Some say add spring rate, or else the valves won't be controlled proper. Some use a rough rule of thumb to add X pressure for Y boost, especially if taking an existing boosted engine from an old boost level to a new much higher boost level. Others say just try what 'ya got and see if it works, which seems a bit unscientific. Seems to me like a confusing topic with fuzzy logic. Anyone want to jump in with some thoughts? Thanks.
