When you add boost you need stronger valve springs..If your gunna be that anal with saying valve springs then there should be different classes for guys who changed diff gears or do work to the gearbox as thats a performance issue,not a reliability issue

That's the whole issue in our racing world, there are no rules you can say and do as you please. Until there are such rules in place like in say ANDRA drag racing and scrutineered by people who know the game until then it's run what you brung.......
