Thread: home made winch bar

Rhys what boost guage are you using? If the performance is a lot better the reading may be out. However I don't think there's much risk of overboost. Monitoring EGTs accurately is far more important.

If you want to try another T3 start looking out for a T3 fitted to a Saab or Volvo. They seem to have both used a similar T3 with a low exhaust AR.

cheers everyone

Waste gated turbos use a smaller turbine (impeller size or housing A/R) to spin up with the exhaust produced at lower load/rpm but needs the waste gate to open to control boost and exhaust pressure at higher load/rpm. With the larger turbine the boost pressure is a limited by the energy in the exhaust.

Back out the full load fuel screw on the side of the injection pump to increase the fuel rate and thus the boost pressure.
