Turbosmart IWG75 Fiat 124 Spider/500T/L/X/Abarth 2012+ 10psi Outer Spring Fitted (TS-0629-1102)
This Improved 'working ratio' is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted, resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.
Upgrading with the same base pressure as the factory, you can expect a broader boost & torque curve through peak boost being achieved earlier in the RPM and being held longer into higher RPM. These improvements can be amplified with higher base pressures. However, tuning & recalibration is likely required.
Available In
7psi / 0.5 BAR: TS-0629-1072
10psi / 0.7 BAR: TS-0626-1102
Features
Proprietary Silicon Nomex Diaphragm
Choice of Springs from 3psi to 26psi (Optional)
High-Grade Billet Aluminum Construction
Stainless Steel Rods and Clevis
Turbosmart Unique Locking Collar System
Note: The 7psi version is suitable as a direct replacement and will work with the factory calibration. Alternative spring combinations will require supporting modifications or engine tuning/recalibration.
