Andy M's problem
http://www.saabscene.co.uk/ubb/ultimatebb....3/t/000761.html
got me wondering: is there a problem with running a dump valve (of whatever type) that has a 'strong spring'?
Provided the system is still able to release pressure in-extremis, is this actually a good way to run a car - allowing boost/pressure levels to stay as high as possible for as long as possible, before releasing only as much pressure as is neccessary (with a small PHSST) to ensure no turbo stall?
And what of running a spring too soft?
Is this the 'hard' and 'soft' setting of adjustable valves? And if it is, why would you want to be able to change?
