but I bristled a bit at the suggestion that I had given misinformation
I never quoted or said which information was wrong... but there is incorrect information given in this thread...

if you compare the force exerted by two springs
why introduce more variables? this is a simple system.. a force acting on a spring. i.e. the waste gate diaphragm acting on a spring.. If you take the spring, and make it shorter... the spring rate goes up! nothing suspicious or tricky... its what happens... so now you have your waste gate diaphragm acting on a spring with a higher rate... your low boost threshold is higher..

The longer the wire is the lower the spring rate. As the wire get shorter, such as when cutting the coil, the spring rate increases.
Quoted from Eaton... spring mfg..

the helical spring is analogous to a torsion bar, not a lever
Yes kinda maybe yes..
