I had my r33 gts mapped to run 1.1 bar with the spec at the bottom of the page. However just recently I have not been able to get more than 0.7 bar of boost.
The car seems to run fine at lower boost but won’t get over 0.7 bar. Even if I remove the boost line to the actuator the car will noot boost past 0.7. Initially I thought it was a boost leak but I tested the system up to 1.2 bar with a compressor (blocked the intake) and it held 1bar of boost with no problems. I have checked the preload on the actuator and tested to boost controller and all seem to be working fine. I am running out of options, has my turbo got a mechanical problem, there seems to be no other option
Dyno’d at 357.5 at the hubs running 1.1 bar.
