SBR T-25 wastegate actuator

[Ginglingston11]

hey guys, i have noticed just recently my cars not holding boost anymore. i have a stock car with minor mods. i have a mbc hooked up and the boost cranked to 22psi (yes i know thats alot on a t-25 and i dont wana hear it because my car held 22 psi for over a year and not one problem and believe me i beat on my car everytime i start it up) so anyway my car will hit 23psi and drop immediately to 15-16psi and hold there. i think its my wastegate actuator and i noticed SBR has one for the t-25 im just looking for something to hold me over until im done saving for my new setup. let me know if u guys think its the actuator or not? oooo and im not leaking any oil

Not worth the money for a t25, its not the actuator its the fact that the t25 is so small and isn't able to keep up the airflow in the higher rpms. Its normal for a t25 set at 16 psi to drop to 12 to 13 psi by redline. Only thing you can do is get a larger turbo. Im surprised your t25 has lasted as long as it has since you are way out of its effiency range and just blowing hot air, do you actually think you are making more power at that kind of boost instead of 16 psi which people normally run, which would still be in its effiency range. Some guy get away with abit more but only if you have an upgraded IC to cool the super heated charge down more.

On a bolt-ons car a T25 will not hold anymore than 15psi after 5500-6000 rpms.

Ps Check for Boost Leaks.
