Product Description.
Custom tailoring your TiAl waste gate to perform how you want it to. Wastegate springs are available for most popular TiAL wastegate models, in a wide variety of spring pressures. Springs install easily with simple hand tools.
The 0.25 thru 0.6 bar springs are small OD and the 0.7 thru 1.0 bar springs are large OD. You can achieve higher pressure by installing both large and putting a smaller spring in the same gate. Simply add the two spring values together to get the new pressure.
