This setup spring is used with the Nuke Performance 50mm blow-off valve to calibrate its setting to your needs. To get the effect you want from your new blow-off valve you will need to use the correct setup for your current engine specification. Engine vacuum should be measured at idle and with the engine up to operating temperature. Nuke has three different springs to choose from, all designed for perfect fitment and performance in combination with our 50 mm blow-off valve. Check the chart below to get to know which spring setup you should go with. Spring rates:
